A61B 17/08

US Classification:

606153

Abstract:

A medical instrument for engaging tissue includes a flexible shaft, a tissue piercing coil at a distal portion of the shaft, and a tissue stabilizer positioned over the shaft and biased in a distal direction such that as the tissue piercing coil enters tissue, the tissue stabilizer is urged against a surface of the tissue. A medical instrument for reconfiguring tissue includes a flexible shaft defining a lumen housing actuating controls, and a distal actuating assembly with a sealing portion configured to substantially seal the shaft lumen from contact with bodily fluids. A cartridge assembly includes first and second members configured for releasable attachment to a medical instrument, and a holder configured to receive the first and second members and to be released from the first and second members upon action of the first and second members attaching to the medical instrument.

International Classification:

A61B 17/04

US Classification:

606139

Abstract:

A method includes advancing an apparatus having an elongated member transorally into the stomach. The apparatus includes a distal end effector having first and second members configured to engage tissue. The first and second members are movable relatively toward one another generally in a first plane. The method includes moving the distal end effector relative to the elongated member in the first plane such that the distal end effector is retroflexed out of alignment with the elongated member to position the first and second members for engagement with the tissue. At least one of the first and second members carries a fixation device for fixing engaged portions of tissue together.

International Classification:

A61B 17/10

US Classification:

606142, 606205

Abstract:

An instrument for reconfiguring stomach tissue includes a sealing member that seals a section of a tissue manipulator from contact with bodily fluids. The tissue manipulator includes a first portion that is configured for releasable coupling to an actuating member and a second portion configured to receive an implant to be deployed within the patient. The tissue manipulator also includes a rectangular member and a cavity for receiving a coupler of the actuating member. The tissue manipulator has a first member with tissue penetrating elements and a second member with engaging elements configured to deflect the tissue penetrating elements upon relative movement of the first and second members. The actuating member includes a tissue penetrating element support positioned to limit bending of the tissue manipulator. The instrument includes an actuating mechanism that is configured to move at least one of the first and second members of the tissue manipulator.

International Classification:

A61B 17/068

US Classification:

2271751, 227 19

Abstract:

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.

US Classification:

2271751, 227 19

Abstract:

A surgical fastener applying device having a handle with a trigger pivotably attached thereto and movable within a trigger plane. The trigger has a bottom portion extending from the handle and a top portion disposed within a housing of the handle. The device has a staple housing with a proximal end attached to the handle, a distal end extending therefrom and a longitudinal axis therebetween. The housing has a firing bar disposed within, and the trigger is coupled to the firing bar. The device has a link member with a first end pivotably attached to the top portion of trigger, the link member has a second end comprising a slidable pin. The pin engages a three dimensional cam path disposed within the housing. The link member follows distal and proximal movement of the top portion of the trigger, and the pin slides perpendicular to the trigger plane to follow the three dimensional cam path.

Abstract:

A fastener applying device including a staple housing having a proximal end attached to a handle, a distal end, and a longitudinal axis therebetween. There is at least one fastener within the housing. The device also includes an anvil movable within the staple housing.
