Abstract
A tissue fastening device includes a body including a plurality of sidewalls defining a channel, an anvil having a proximal end and a distal end and pivotally coupled to the body and the anvil moves between an open position and a closed position, and a locking mechanism to lock the anvil in the closed position.
Claims14
A tissue fastening device comprising:
- a body including a ramp and a sidewall, wherein the sidewall includes a slot that extends along a longitudinal axis of the body;
- an anvil pivotally coupled to the body, wherein the anvil is configured to move between an open position and a closed position, and wherein the anvil includes a pin;
- and
- a wire coupled to a proximal end of the anvil;
- wherein the ramp includes (i) a sloped surface on a distal end of the ramp and (ii) a top surface parallel to a bottom surface of the body, wherein the body and the anvil are configured such that movement of the wire in a proximal direction causes the anvil to slide along the sloped surface of the ramp and the pin to slide proximally along the slot of the body, so that the proximal end of the anvil moves onto the top surface of the ramp, thereby locking the anvil in a closed position.

A tissue fastening device comprising:
- a body including a ramp and a sidewall, wherein the sidewall includes a slot that extends along a longitudinal axis of the body;
- an anvil pivotably coupled to the body at a pivot, wherein the anvil includes a pin;
- and
- a wire coupled to a proximal end of the anvil, wherein the body and the anvil are configured such that proximal movement of the wire moves the proximal end of the anvil proximally along a sloped surface of the ramp and onto a top surface of the ramp in order to transition the anvil from an open position to a closed position and to lock the anvil in the closed position, and wherein the body and the anvil are configured such that the proximal movement of the wire moves the pin proximally through the slot.
1 more element
A tissue fastening device comprising:
- a body including:
- a ramp, wherein the ramp includes two ramp bodies defining a channel between the ramp bodies;
- and
- a sidewall, wherein the sidewall includes a slot that extends along a longitudinal axis of the body;
- an anvil including a pin, wherein the anvil is pivotally coupled to the body by the pin engaging the slot and sliding relative to the body within the slot, wherein the anvil is configured to move from an open position to a closed position as the pin slides proximally through the slot;
- and
- a wire coupled to a proximal end of the anvil, wherein the wire extends through the channel in the open position of the anvil, wherein the proximal end of the anvil is distal to the ramp in an open position of the anvil, wherein proximal movement of the wire causes the proximal end of the anvil to move proximally, up a sloped surface of the ramp and onto a top surface of the ramp, thereby closing the anvil.
