A surgical tool for performing anastomosis may include a staple holder; a clip detachably connected to the staple holder; a length of suture, wherein a portion of the length of suture is held securely between the clip and the staple holder; and a needle connected to the suture. An incision may be made at one end of the graft vessel to form a flap. The needle may penetrate the wall of the graft vessel proximal to the incision, and the graft vessel may then be parachuted down the suture toward engagement with the clip. In this way, graft loading onto the clip is facilitated.

A single measurement tool is configured to measure at least two characteristics of a patient's vasculature during a surgical procedure such as a coronary artery bypass graft procedure. The measurement tool includes an indentation defined therein that is placed against a tubular structure such as the aorta to determine whether that tubular structure has a radius larger than or smaller than the radius of curvature of the indentation. The measurement tool may include a number of first recesses for measuring the diameter of a tubular structure. The measurement tool may include at least one second recess for measuring the wall thickness of a tubular structure.

A single measurement tool is configured to measure at least one characteristic of a tubular tissue structure during a surgical procedure. The measurement tool may include an indentation defined therein that is placed against a tubular structure such as the aorta to determine whether that tubular structure has a radius larger than or smaller than the radius of curvature of the indentation. The measurement tool may include a number of first recesses for measuring the diameter of a tubular structure. The measurement tool may include at least one second recess for measuring the wall thickness of a tubular structure.

A surgical tool may include a circular surgical stapler and an anvil initially disconnected and separate from the surgical stapler; where at least one of the circular surgical stapler and the anvil is magnetic.

A surgical method for treating a tissue structure having a wall and a lumen may include providing a substantially rigid anvil and a flexible tip affixed to and extending from the distal end of that anvil; making an incision in the wall of the tissue structure; inserting the flexible tip and at least a portion of the rigid anvil through the incision into the lumen of the tissue structure; and deforming at least one connector, introduced from outside the wall of the tissue structure, against the portion of the rigid anvil located within the lumen of the tissue structure.
摘要:
A surgical apparatus may include at least one feeder belt; a plurality of staples frangibly affixed to each feeder belt, where each staple includes two ends, a first end frangibly connected to a corresponding feeder belt and a second, free end; and a handle within which at least part of at least one feeder belt is received, where that feeder belt extends along a path within that handle that is at least partially nonlinear. A method for operating a surgical apparatus, including providing a surgical stapler including an end effector, a shaft, a handle and at least one feeder belt, where staples are frangibly affixed to each feeder belt; deploying a plurality of staples from the end effector; and advancing at least one feeder belt along a nonlinear path after deploying the staples, whereby fresh staples are moved into the end effector into position for deployment.

A method for closing an aneurysm in a blood vessel may utilize a staple having two or more tines, where those tines are oriented at least partially in the proximal direction. The method may include advancing the staple through the vasculature to a location within the aneurysm, plastically deforming the staple to a splayed configuration, penetrating at least one said tine of the staple in that splayed configuration into tissue in proximity to the neck of the aneurysm, and plastically deforming the staple to a closed configuration to close the aneurysm.

A method for connecting a graft vessel to a target vessel may involve advancing a guidewire of a surgical stapler into the target vessel through an opening at a first location on the target vessel, coupling a stapler cartridge carrying the graft vessel with an anvil of the surgical stapler, activating the anvil to staple the graft vessel to the target vessel at a second location on the target vessel, removing the guidewire from the target vessel, and closing the opening in the target vessel.
摘要:
One example of surgical apparatus for treating tissue may include an effector including at least two jaws movable toward one another, where the effector holds and is configured to deploy a of clips in a clip application mode, and where the jaws are configured to deliver energy to coagulate tissue in a coagulation mode, where said effector is switchable between clip application mode and coagulation mode. Another example of surgical apparatus for treating tissue may include an effector holding clips, and two fingers movable toward one another to close the clips one at a time, where each finger is a different pole of a bipolar coagulator. An exemplary method for treating tissue with a surgical apparatus may include placing the surgical apparatus adjacent to tissue at a location, selecting one of a plurality of operational modes of the surgical apparatus, where the operational modes include clip application mode and coagulation mode, and actuating the surgical apparatus according to the selected operational mode.
