OESOPHAGUS STENTS (GEN-I)

A comprehensive selection of self-expanding stents for bypassing oesophageal
stenoses. The stents are characterised by very high flexibility and are available with and without covering. The working diameter of the stent is 20. 24 or 28 mm while lengths vary of between 60 and 140 mm. Therefore, the optimum solution is always at hand for every indication.

SpecificCharacteristics

• Self-expanding
• Nitinol mesh with atraumatic ends
• Excellent positional stability
• High radial force
• Resistant and elastic covering
• Fully covered stents available
• Parylene coated
• High radiopacity
• Extraction threads for removal and repositioning
• Guide wire-compatible up to 0.035 inches

Practicable

The stent adapts to the oesophageal wall in the best
possible manner thanks to its atraumatic shape and high
radial force. Furthermore, the stent possesses excellent
radiopacity and can be positioned with good visibility and
precision at significant points with the aid of the additional
X-ray markings.

Positionally Stable Design

The oesophagus stent is extremely positionally stable.
Its self-expanding Nitinol wire adapts itself perfectly to
the patient’s anatomy and the atraumatic ends ensure a
maximum hold.

Diameters up to 28mm

Three different diameters:
20. 24 or 28 mm in the central section. The stent end is
6 mm wider in each case.

Five Standard Lengths

Short stents
measuring 60 and 80 mm, medium lengths of 100 and
120 mm and long versions of 140 mm.

Radiopaque Markers For Secure Insertion Of Stents

All of our esophagus stents are equipped with up to 10 radiopaque markers. They are clearly visible under radiological control and thus enable a secure and precise stent release.

With And Without Covering

Depending on the model, the stents have a protective covering. Choose between a complete covering from one stent end to the other, a partial covering in which the ends remain free and a cover-free stent.

Point Of No Return

A mark on the delivery system shows the “point of no return” at stent placement.

Introducer For Precise Release

All stents are preloaded on the easy-to-manipulate introducer, which allows rapid and precise stent release. The system also allows you to bring the stent into the desired position even when in the oral cavity during release.

SPECIFICATIONS

CARDIA-UMBRELLA-STENT

A specially designed stent perfectly tailored to the challenging anatomical diagnosis of the cardia. Its unique design gives the stent extremely high positional stability and prevents its migration in both the gastric and oral directions. Since the lower oesophageal sphincter lies between the bulbous section and the distal end of the stent we have implemented a special feature which is an “opened umbrella” type shape to facilitate this anatomical challenge. Furthermore, the stent does not protrude into the stomach as a result of this umbrella-shaped design, ending directly behind the oesophageal gastric junction. The risk of pressure necrosis is thus significantly reduced and any potential patient discomfort is decreased.

Specific Characteristics

• Unique umbrella design
• Self-expanding
• Nitinol mesh with atraumatic ends
• Excellent positional stability
• High radial force
• Resistant and elastic covering
• Fully covered stents available
• High radiopacity
• Extraction threads for removal and repositioning
• Guide wire-compatible up to 0.035 inches

Together with the high radial force, the spherical proximal end and the complete covering, the innovative umbrella design guarantees ideal hold in the area of the cardia. Radiopaque markers in prominent positions ease the placement of the stent under radiological view.

DUODENUM STENTS

The self-expanding Nitinol stents are used to bypass stenoses in the duodenum. Their spherical ends adapt perfectly to the anatomy of the duodenum, thereby guaranteeing maximum positional stability. Stents with and without covering are available depending on the indication. The duodenual stent is preloaded on a TTS introducer (through-the-scope) as standard. Insertion is therefore carried out through the working channel of the endoscope and release of the stent is observed endoscopically. X-ray markings on the introducer and on the stent itself ensure optimum radiological visualisation.

Specific Characteristics

• Spherical ends
• Self-expanding
• Nitinol mesh with atraumatic ends
• Release under endoscopic observation
• Excellent positional stability
• Resistant and elastic covering
• High radiopacity
• Extraction threads for removal and repositioning
• Guide wire-compatible up to 0.035 inches

With a diameter of 20 mm and different lengths of 60.
80. 100 or 120 mm, the range of duodenual stents always
provides the right size for your patient.

SPECIFICATIONS

BILIARY DUCT STENTS

The high expansion force of the Nitinol wire mesh accounts for an excellent positional stability. The resistant cover prevents the stent from growing into the tissue. The product range comprises two stent lines and offers a first-class solution that suits all requirements: the classic line and the platinum line. The comprehensive platinum line is especially distinguished by its extraordinary high radiopacity.

Specific Characteristics

• Self-expanding
• Available for TTS and PTCD
• Classic- and Platinum-Line
• Nitinol wire mesh with atraumatic ends
• Release under visual endoscopic control
• Enormous position stability
• Resistant and elastic cover
• High radiopacity
• Guiding wire passable to a maximum of 0.035 inches

The Classic-Line is perfectly suited for all standard interventions. With two different approaches consisting of TTS and PTCD, it perfectly meets every requirement. These stents are made of highly flexible Nitinol wire mesh. Ten additional radiopaque markers account for the good visibility of our Classic-Line stents under fluoroscopy. Our product range comprises uncovered and partially covered stents.

PTCD For Percutaneous Access

In case of therapeutic interventions into the biliary duct, it sometimes occurs that a transpapillary access cannot be accomplished. In such cases MICRO-TECH offers PTCD systems (percutaneous transhepatic cholangio drainage) as the ideal solution.

TTS Stents For Routine Interventions

We offer uncovered as well as partially covered biliary duct stents in three different lengths. All stents can be placed through the working channel of the duodenoscope over the inserted guide wire (TTS – through-the-scope).

Introducer System For An Exact Release

Additional radiopaque markers on the distal end of the introducer system and on the tip of the pusher catheter provide for additional orientation. In the endoscopic image, the tip of the pusher catheter can be unambiguously and easily distinguished from the proximal end of the stent. The permanent visual endoscopic control of the stent‘s proximal end considerably facilitates the exact release of the stent.

Ten Platinum Radiopaque Markers

In order to achieve improved visibility under X-ray control each stent bares a total of ten radiopaque markers: four markers located at each end, and two in the middle of the stent. The two radiopaque markers in the middle guarantee for the controllability of the stent‘s optimal position during deployment.

Specifications

BILIARY-STENT (GEN-II)

Thanks to its slim design, the system can be pushed almost frictionless through the endoscope and released easily in the bile-duct. A high flexible, specially developed Nitinol wire and the tantalum markers ensure optimal placement under X-ray vision. The range of stents are available in lengths from 40 to 100 mm as well as fully, partially and uncovered stents. Uncovered and partially covered variants are produced with a “point-of-no-return” that allows to re-insert the stent into the sheath again and make the repositioning much easier.

Specific Characteristics

• Slimmer introducer set
• Point-of-no-return for uncovered and partially
covered stents
• Stent system does not need to be flushed
before application
• Stent with tantalum marker for good visibility
under X-ray

Specifications

SHOW-METAL-STENT

Indicated for applications in the bile duct and is suitable for both short and long wire systems. Time-consuming preparation and irrigation is no longer necessary. Made of flexible nitinol wire, the stent is designed to adapt ideally to biliary conditions. The atraumatic stent ends are characterized by their soft edges. For precise placement, there are overall 10 radiopaque markers on the stent itself and three more on the introducer set. The point-of-no-return (for uncovered and partially covered stents) allows resheathing of the stent which means it can be repositioned. The guide wire exit is located at approx. 30 cm. Our range includes stents with four different lengths of 40 to 100 mm and thus offers for each operation the ideal solution.

Specific Characteristics

• Short and long wire compatible
• No preparation or flushing necessary
• Easy handling
• Uncovered, partially covered and fully covered
• Available in a straight form
• Automatic guide wire exit
• Point-of-no-return
• Very good visibility through tantalum markers
• Very flexible application system facilitates the
placement

PLATINUM-LINE

Under X-ray control, they are more visible than ever before, making their release even safer and precise. The secret of their extremely good visibility lies in the specially developed Nitinol wire. Now with enhanced radiopacity, these platinum stents virtually glow in X-ray images. This accounts for extremely good visibility of the stent over its entire length under fluoroscopy.

Apart from the innovative Nitinol wire, each stent of the Platinum-Line is distinguished by two additional radiopaque markers which are located in the middle of the stent. This enables pinpointing the exact position of the stent‘s center line while the stent is being released. Additional radiopaque markers on the introducer system also facilitate orientation.

The biliary stents are 10 mm wide throughout and differ in length according to the indication: a choice of five lengths is available, namely 40. 60. 70. 80 and 100 mm.

Specifications

PSEUDOCYST STENT (GEN-II)

The Pancreastic pseudocyst stent is used for reliable drainage of endoscopically removed concrement. The design of the stent with its distal umbrella and proximal tulip shapes, ensures that during an eventual migration a dislocation would only occur into the stomach and not into the cyst. The large diameter of 16 mm in the middle of the stent allows for endoscopic removal of concrement. The 10.5 French TTS (through-the-scope) insertion system is brought into position through the working channel of the endoscope with the aid of a guide wire. When the stent is released, 4 radiopaque markers at each end of the stent guarantee excellent identification on radiological images.

Specific Characteristics

• Stent with complete silicone covering
• High degree of positional stabilityl
• Atraumatic tips
• High level of radial force
• Tantalum radiomarkers
• Guide wire passage up to 0.035 inches
• TTS insertion system with 3.5 mm diameter,
1,800 mm length, two x-ray markings, rinsing
attachment and lock to secure the introducer
set during transport, storage and insertion.

COLONIC STENTS TTS

Whereas OTW systems can be placed over-the-wire, TTS (through-the-Scope)colonic stents can be delivered though the working channel of the colonoscope. This way, application time is reduced dramatically. Due to the visible endoscopic control during placement stent deployment takes place in an even more controlled fashion. In comparison with OTW colonic and rectal stents, TTS applications are especially flexible and better suited for the curved segments of the colon, e.g. the right and left colonic flexures.

Specific Characteristics

• Self-expanding
• Nitinol wire mesh with atraumatic ends
• Flexible and positionally stable
• 10 Radiopaque markers for enhanced visibility
under X-ray
• Extraction threads for removal and repositioning
• Guide wire passable up to 0.035 inches

As a standard among TTS colonic stents, you can choose from four different lengths: 60, 80, 100, and 120 mm for stents without covering. In all other versions the stent end working diameter amounts to 25 mm and to 30 mm. The introducer system for TTS colonic stents has a diameter of 10 fr. (= 3.3 mm). It therefore fits to all working channels having a diameter of at least 3.6 mm.
