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 method for deploying fasteners including the steps of providing a device having 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 and an elongated pusher movable through the hollow housing from the distal to the proximal end for deploying the fastener from the distal end. The method includes increasing the stiffness of the pusher at a distal end thereof and advancing the pusher through the elongated housing to deploy the fasteners.

A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing having a proximal position and a distal position. When the anvil is in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop, wherein at least one fasteners is placed around the anvil when the anvil is in distal position. And a distal end of the anvil extends distal to the distal end of the staple housing. The applier further includes a first means for moving the anvil distally during a deployment of the at least one fastener, and a second means for moving the anvil distally during the deployment of the at least one fastener, wherein the second means is independent of the first means.

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.

An apparatus comprises a surgical instrument and a buttress configured to hold a fluid adhesive. In some versions, the buttress contains a two-part fluid adhesive where two fluid materials form a fluid adhesive when combined. In some versions, the buttress is configured to be compressed by the surgical instrument thereby pressurizing a portion of the buttress. Thereafter, the buttress may be severed and the pressurized region may be operable to urge the fluid adhesive to a tissue site.
摘要:
A surgical device comprising a clevis defining a longitudinal axis and a jaw comprising a first member and a second member. A slider is slidably engaged to the clevis, the slider comprising a pin. The pin is receiveably engaged in the first slot and the jaw is selectively moveable between a first position and a second position through longitudinal movement of the slider. In various embodiments, the first and second members are movable between an angular open position, a parallel open position, and a parallel closed position.

A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing, the anvil has a proximal position and a distal position. When in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop. At least one of the fasteners is placed around a portion of the anvil when in the distal position. The applier has a first mechanism for moving the anvil distally after a fastener has been deployed, and a second mechanism for moving the anvil distally after a fastener has been deployed. The second means is independent of the first means.

Methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided that includes a housing having at least one access or sealing port for receiving a surgical instrument, and a retractor removably coupled to the housing and having a working channel configured to extend into a body cavity. The housing can include releasably matable upper and lower portions, with the upper portion being configured to freely rotate 360° relative to the lower portion and to the retractor when the housing is mated thereto.
摘要:
A method of deploying a surgical fastener including the step of introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method involves moving the end segments of the fastener in a first manner away from each other while maintaining the fastener in a closed loop. The method also involves moving the end segments of the fastener in a second manner away from each other to open the loop. The method further involves forming the fastener into a second loop having a width greater than the width of the first loop.
