摘要:
A marking apparatus includes a selectively inflatable balloon. The balloon includes an external lumen adapted for connection to a vacuum source. The external lumen includes ports for creating a vacuum at the ports sufficient to draw walls of the gastric cavity into contact with the external lumen. The balloon is further provided with RF energy delivery devices. In accordance with an alternate embodiment, a marking apparatus includes an elongated, hollow body, the hollow body including a proximal end and a distal end. The hollow body includes at least one suction trough in which a plurality of holes is disposed to draw suction on tissue. The at least one suction trough extends along a substantial portion of the hollow body as it extends from its distal end to its proximal end.
摘要:
An inflatable medical instrument for tissue damage in gastric reduction surgery includes a main chamber composed of a biocompatible material capable of being selectively inflated. The medical instrument also includes a longitudinally extending tab member secured to an outer surface of the main chamber, a series of suction holes are formed along the tab member and an electrode is mounted on the tab member. The present invention also provides a method for forming a tissue junction used in defining a gastric pouch including damaging opposed tissue layers, apposing the tissue layers and fastening the tissue layers to allow the tissue layers to heal together.

摘要:
A cartridge containing a fastener. The cartridge has an elongated sheath containing at least one tissue penetrating member. The penetrating member at least partially houses a fastener. The fastener has at least two anchors connected together by a non-resilient flexible suture which does not resist deformation under compressible loads. The cartridge further includes a means for deploying the anchors, wherein the means is movable within the sheath.
摘要:
A device for deploying fasteners including a handle and at least one actuator. The handle is connected to an elongated hollow housing having distal and proximal ends. The device has a first cartridge containing at least one fastener releasably connectable to the handle. The device also includes an elongated pusher movable through the hollow housing from the proximal to the distal end to deploy the fasteners. The device further includes a deforming member for deforming the pusher at a proximal end thereof while advancing the pusher to the distal end of the housing.
摘要:
Endoluminal sleeve device (1) for internally lining a section of the GI tract, comprising a sleeve (2) configured for deployment inside a GI tract, the sleeve (2) having walls of a flexible material defining a sleeve lumen (3), a proximal end (4) defining a proximal lumen opening (5), and a distal end (6) defining a distal lumen opening (7), a tubular anchoring portion (8) forming said proximal lumen end (4) and defining anchoring seats (9) delimited each one by an annular collar (11) forming an opening through which adjacent tissue portions (12) can be pulled into the anchoring seats (9), expansion means adapted to act on the tissue portions (12) arranged in the anchoring seats (9) such that the tissue portions (12) expand to a dimension greater than the opening of the annular collar (11).

摘要:
A reloadable device for deploying fasteners. The device has a handle and at least one actuator. The handle is connected to an elongated hollow housing having distal and proximal ends. The device has a first cartridge containing at least one fastener releasably connectable to the handle. The fastener has at least two anchors connected together by a non-resilient flexible suture which does not resist deformation under compressible loads. The device also includes a means, adjacent the handle, for facilitating removal of the first cartridge from the handle and replacing it with a second cartridge.
