An intestinal intraluminal reconstruction and resection device includes a mechanism for intussusception of the bowel, a bowel anastomosis mechanism and a mechanism for severing the resected bowel. The surgical device allows the user to carry out intraluminally an anastomosis first, prior to resection of the intestine or any hollow viscus, therefore not exposing the dirty intraluminal content to the clean abdominal or thoracic cavities. The above is achieved by first intussuscepting the hollow viscus, then anastomosis and finally intraluminal resection.

A two piece anastomosis device for attaching two organs together and creating a passage between the organs is disclosed. The anastomosis device has a first tissue clamping ring and a second tissue clamping ring that are brought together to clamp tissue therebetween and cut off the flow of blood to the tissue. The tissue clamping rings are locked together with an adhesive, and over time, causes the clamped tissue to necrose and slough off. The sloughed tissue creates a passageway through the anastomosis device. A method of using the fastener to create a bypass passageway between the stomach and small intestine is disclosed.

An apparatus for performing anastomosis between a graft vessel and a target vessel may include a connector holder having spaced-apart arms, and a member connected to the connector holder, where the member is insertable through an opening in a wall of the target vessel at least partially into the lumen of the target vessel. One or more connectors, such as staples, may be deployed from each arm to connect the graft vessel to the target vessel. One or more connectors may be deformable against the member.

A combination medical device comprising a circular stapler instrument (4) and one or more portions of preformed buttress material (16) adapted to be stably positioned upon the staple cartridge (12) and/or anvil (14) components of the stapler (4) prior or at the time of use. Positioned buttress material(s) (16) are delivered to a tissue site where the circular stapler (4) is actuated to connect previously severed tissue portions. An embodiment of the invention allows tissue portions to be joined without the use of sutures. The buttress material (16) is made up of two regions, one of which serves primarily to secure the buttress material (16) to the stapler (4) prior to acuation, and one of which serves primarily to form the improved seal. The former region is severed and discarded upon activation of the circular stapler (4) to form anastomoses, while the remaining material secures and seals the newly connected tissue. Methods of use and preparation of the buttress material (16) are also described.

Devices for attaching a first mass and a second mass and methods of making and using the same are disclosed. The devices can be made from an resilient, elastic or deformable materials. The devices can be used to attach a heart valve ring to a biological annulus. The devices can also be used for wound closure or a variety of other procedures such as anchoring a prosthesis to surrounding tissue or another prosthesis, tissue repair, such as in the closure of congenital defects such as septal heart defects, tissue or vessel anastomosis, fixation of tissue with or without a reinforcing mesh for hernia repair, orthopedic anchoring such as in bone fusing or tendon or muscle repair, ophthalmic indications, laparoscopic or endoscopic tissue repair or placement of prostheses, or use by robotic devices for procedures such as those above performed remotely.

A method for forming an anastomosis between first and second organs in a patient using a hollow receptacle that is inflatable with magnetic material. The method may include forming openings through the first and second organs utilizing a hole-forming instrument inserted into the organs through a natural orifice in the patient. The hollow receptacle may be supported on a catheter assembly that is also inserted through the patient's natural orifice and through the openings in the first and second organs and is positioned within the second organ. The hollow receptacle is then inflated with magnetic material and magnetic force is applied within the force organ to draw the inflated receptacle toward the first organ such that the inflated receptacle retains the second organ in sealing contact with the first organ while maintaining the alignment between the first and second openings to create an anastomosis between the first and second organs.

The invention relates to a binding mechanism of a surgical binding apparatus, which is placed at the head of the surgical binding apparatus and includes a nail pin, a nail pushing plate and a nail block. The nail pushing plate and the nail pin are installed inside the binding apparatus body. The positions of the nail block and the nail pushing plate are opposite. The invention is characterized in that the working faces of nail pin, the nail pushing plate and the nail block are not at the same plane and at least present a step-type fall distributed structure. When the structure is adopted to form an anastomoses opening, the distance between two lines of nails is enlarged; the elasticity of the anastomoses opening which is formed in the operation is increased and is more close to the physiological characteristic of the tissue, which is in favor of the prompt recovery of the tissue. When the nail block is set out from an anastomoses ring or a content object is put through the anastomoses ring after binding, the elasticity of the anastomoses ring becomes larger to allow the nail block or the content object pass through and reduce the probability of damaging the anastomoses ring.
