Described herein are devices used for treating a fistula, along with methods of treatment thereof, and methods of manufacturing the device.

This application discloses an occlusive device that includes a frame movable between a deliver condition and a blocking condition, the frame including a center region, a plurality of distal arms, a plurality of proximal arms, where both the distal and proximal arms curve away from the center region, with flexible sheet material couple to both the distal and proximal arms that block a lumen when the frame is in the blocking condition. Also disclosed is a method of manufacturing the occlusive device and a medical device incorporating the occlusive device.

Biocompatible wound closure devices including an elongate body and a plug member are useful for wound repair.

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

An implant 801 for closing an opening in tissue such as a fistula or a sinus comprises a coil having a substantially uniform outer diameter. The coil forms an internal passage having a diameter that tapers from a distal end to a proximal end. The implant 801 may be delivered using a non-tapered driver coil 820.

A fistula treatment system comprises a guide such as a guide coil 1101 which is adapted to extend partially around a tissue tract and an implant element 1102. The implant element 1102 is activated to draw tissue surrounding the tract inwardly.

Described are expanded collagenous materials and methods for their preparation and use. Certain expanded collagenous materials can be prepared by treating a first collagenous material with an alkaline substance under conditions effective to expand the first collagenous material, and recovering the expanded material. Expanded materials can exhibit beneficial persistence and tissue generation characteristics when implanted, and can be used in the formation of highly porous medical implant bodies which can be compressed to fractions of their original volume and will thereafter substantially recover their original volume.

The present invention is related to an apparatus to close and control the fistula especially in the enteroatmospheric fistulas occurred in surgical patients, characterized in that it comprises a silicon plug (1) that is made of silicon, and has a flexible, flat and circular shape; a2 connection part (2) that is integrated with silicone plug (1) made of same material and connecting the silicon plug to the suspensory band; at the other end of the connection part, a suspensory band (3) made of latex and having flexible circular form; and a bridge part (6) which is connected to the said structures in order to carry thereof, two surfaces of which are covered with thin sponge part (4), which has an easily bendable thickness and softness, and comprises an aluminum part (5) between sponge parts (4) at the center.

A drainage device may include a catheter including a proximal end and a distal end. The drainage device may further include a hub coupled to the proximal end of the catheter. The hub may include a fastener element configured to secure the distal end of the catheter. In some aspects, the fastener element may be a hinged element. In some aspects, the drainage device may further include a puncture element including a tip and an expander portion. In still other aspects, the puncture element may also include an attachment portion.
