摘要:
A tool that has an introducer having a space therein and a distal aperture at the distal end thereof, and a spike movable within the introducer, may be used in a surgical method for treating a vessel wall. A tissue plug may be removed from the vessel wall with the spike, whereby an opening remains in the vessel wall. The spike then may be moved within the space in the introducer in a direction away from the longitudinal centerline of the distal aperture. An object then may be delivered through the introducer and out of the distal aperture to the opening in the vessel wall.
摘要:
An anastomosis system for connecting a graft vessel to a target vessel includes spaced-apart arms, and an anvil connected to those arms, where that anvil has a blunt distal end. The anvil is insertable into the target vessel. One or more connectors, such as staples, may be deployed from each arm to connect the graft vessel to the target vessel.
摘要:
An apparatus for performing anastomosis between a graft vessel and a target vessel may include a trocar that may create an opening in the target vessel. At least part of the trocar may be expandable to allow an anastomosis device to pass through the distal end thereof. The apparatus may include a holder configured to hold the anastomosis device, and place and deploy the anastomosis device in the opening created by the trocar.
摘要:
A surgical tool for performing anastomosis between a graft vessel and a target vessel may include an anvil; a cutting element connected to the anvil; and an energy source connected to the cutting element, wherein the energy source is configured to deliver energy to the cutting element. A method for performing anastomosis with that tool may include placing an end of the graft vessel against a side of the target vessel; creating an opening in the wall of the target vessel at a first location; inserting an anvil through the opening from outside the wall of the target vessel into the lumen of the target vessel; creating an incision in the wall of the target vessel spaced apart from the first location; and connecting the graft vessel to the target vessel.
摘要:
A device for everting an end of a hollow tissue structure may include a mandrel and a collar proximal to the mandrel. The mandrel may be elastomeric and deformable. At least one of the collar and the mandrel may be movable relative to the other. Deformation of the mandrel everts the end of the hollow tissue structure.
摘要:
A method and system for performing anastomosis may use an anvil to control and support a tissue site during an anastomosis procedure involving tissue bonding techniques such as adhesive tissue bonding. Adhesive may be applied to mating surfaces of the graft and/or target vessels either before or after the vessels are brought into contact. Adhesive may be applied via an applicator associated with the anvil.
摘要:
A method for connecting a graft vessel to a target vessel, each vessel having a wall surrounding a lumen, may include providing a connector holder, associating an end of the graft vessel with the connector holder, positioning the connector holder outside of the lumen of the target vessel, outside the lumen of the graft vessel, and in proximity to the outer surface of the wall of the target vessel, and actuating the connector holder to secure the end of the graft vessel to the side of the target vessel.
摘要:
A surgical tool for performing anastomosis may include a handle and a tissue effector connected by a shaft, at least party of which may be flexible. The tissue effector may include a staple holder connected to an anvil.
摘要:
A minimally-invasive coronary artery bypass graft procedure may be performed with a splittable proximal anastomosis tool. A distal anastomosis tool may be used as well, where that distal anastomosis tool may include a staple holder having two spaced-apart arms, staples detachably held by the staple holder, and an anvil connected to the staple holder.
摘要:
A method for anastomosing a first vessel to a second vessel may include connecting an end of the first vessel to the side of the second vessel and creating an opening in the wall of the second vessel from within the lumen of the second vessel, where that opening allows fluid communication between the lumen of the first vessel and the lumen of the second vessel.
