The present disclosure relates to a medical anchor device and methods of use for providing an improved device for intraluminally directed vascular anastomosis. The anchor device includes a generally tubular graft having a flange disposed at one end thereof, where a portion of the graft extends through the flange.

An anastomosis device 3 includes a corrugated circumference section (20;120;120′), a top-side slender member (10a-1;110a-1), and a bottom-side slender member (10b-1;110b-12). The top-side slender member (10a-1;110a-1) is connected to one top section (20a-1;30a-1;120a-1) of the corrugated circumference section (20; 120;120′).

The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections so as to improve tissue viability, prevent tissue ...

The invention is an implantable magnetic anastomosis device having an exoskeleton that directs self-assembly. The design allows the device to be delivered in a linear configuration using a minimally-invasive technique, such as endoscopy or laparoscopy, whereupon the device self-assembles into, e.g., a polygon.

Embodiments of the invention provide systems and methods for using a tissue scaffold to facilitate healing of an anastomosis. One embodiment provides a tissue scaffold for placement at an anastomotic site within a body lumen comprising a radially expandable scaffold structure having lateral and mid portions, at least one retention element coupled to each lateral portion and a barrier layer.

A system for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally.

An organ anastomosis system 1 includes a pair of disc-shaped magnets 2 and 3 which pinch and compress adjacent organ walls 6a and 6b of an object by magnetically attracting each other with the organ walls 6a and 6b interposed therebetween so as to cause local apoptosis and form a continuous hole and an anastomotic part conglutinating around the peripheral part of the ...

An anastomosis device includes magnets coupled to a wire capable of changing shape from a straight wire into a coil when deployed within a body. The coil exerts compressive force upon layers of tissue caught between loops of the coil.

This disclosure provides novel hydrogels that can undergo multiple gel-sol transitions and methods of making and using such hydrogels, particularly in anastomosis procedures. The peptide hydrogels comprising a fibrillar network of peptides that are in an amphiphilic β-hairpin conformation.

A method for treating a patient may include establishing an anastomosis between a pulmonary artery and an aorta; and pumping blood from the pulmonary artery to the aorta when the pulmonary artery has a pressure lower than or equal to a pressure of the aorta.. .

A circular stapler is disclosed. The circular stapler includes a handle assembly, an elongate body, a cartridge assembly, a trocar, and a light source.

A circular stapler is disclosed. The circular stapler comprises a handle assembly, an elongate body, and a cartridge assembly.

Apparatus and methods are provided for treating a human condition by providing an appendage chamber having a thermal exchange member. Negative pressure may be applied to a human appendage when placed within the appendage chamber.

A tissue removal system is provided which enables optimally performing a full-thickness resection of a hollow organ while minimizing invasiveness. In this tissue removal system, a tissue pressing tool which has a tissue contacting part and which is guided into the abdominal cavity, and a resection and anastomosis device work together.

A seal element for sealing between tissue lumens includes a first material for allowing tissue ingrowth and a second sealant material.. .

Devices and methods can be used to treat long gap esophageal atresia, while obviating much of the delay and complexities associated with current procedures. The devices and methods involve actively stretching the esophagus portions with traction to promote growth of the esophagus portions.

A device for anastomosis of a tubular structure comprises first and second hollow members having a rigid part and an elastic part, and a connection member for interlocking the first and second members. The elastic parts are essentially circular rings, and are made of a polymeric, a biocompatible and/or biodegradable material.

The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections so as to improve tissue viability, prevent tissue ...
