Abstract
An embodiment of the present invention relates to an apparatus and method for placement of surgical fasteners. An embodiment of the apparatus comprises an insertion assembly, a handle, and a delivery catheter. The insertion assembly may be a force member, or propulsion assembly, which is integrated within a handle itself attached to a delivery catheter. The apparatus may provide for delivery of at least one fastener through a catheter assembly and its subsequent deployment at a surgical site.
Claims28
An apparatus for placement of surgical fasteners, comprising:
- an insertion assembly having a proximal end and a distal end;
- a handle housing the proximal end of the insertion assembly;
- and
- a delivery catheter attached to a distal end of the handle and housing the distal end of the insertion assembly.
An apparatus for placement of surgical fasteners, comprising:
- a force member having a proximal end and a distal end;
- and
- a handle, within which the force member is integrated and wherein a distal end of the handle is attached to a delivery catheter.
An apparatus for placement of surgical fasteners, comprising:
- a propulsion assembly;
- and
- a handle, within which the propulsion assembly is integrated, and wherein a distal end of the handle is connected to a delivery catheter.
A method for placement of surgical fasteners, comprising the steps of:
- accessing a surgical site with a delivery catheter;
- positioning a force member within the delivery catheter;
- drawing back a pull knob of the force member, thereby extending an expansible member disposed in the mid-section of the force member;
- and
- releasing the pull knob, thereby transmitting energy stored in the expansible member to a piston and thereafter to at least one fastener at a surgical site.
A method for placement of surgical fasteners, comprising the steps of:
- accessing a surgical site with a delivery catheter;
- feeding a force member through the delivery catheter;
- applying manual force to a force rod of the force member to advance at least one fastener;
- separating the force member from the at least one fastener, thereby deploying the fastener;
- and
- withdrawing the force member through the delivery catheter from the surgical site.
A method for placement of surgical fasteners, comprising the steps of:
- accessing a surgical site with a delivery catheter;
- positioning a propulsion assembly within the delivery catheter;
- activating a laser connected to an optical fiber having a hollow core;
- advancing the optical fiber, thereby creating a treatment specific hole at the surgical site;
- deactivating the laser;
- loading at least one fastener into the hollow core of the fiber;
- propelling the at least one fastener to the surgical site by a propellant that enters the hollow core through an inlet;
- and
- withdrawing the optical fiber from the surgical site, thereby deploying the at least one fastener at the surgical site.
A method for placement of surgical fasteners, comprising the steps of:
- providing a delivery catheter extending between a point of proximal access to a distally positioned surgical site;
- positioning a portion of the insertion assembly containing at least one fastening means within the delivery catheter;
- advancing the delivery catheter and insertion assembly housed therein to a surgical site;
- forming a treatment specific hole in a surgical component and tissue by the advancement of a portion of the insertion assembly;
- inserting at least one fastener to an intraluminal side of the surgical component and the adventitial tissue layer;
- and
- deploying the at least one fastener by removing the insertion assembly.
A method for placement of surgical fasteners to occlude a vessel, thereby effecting a reduction in blood flow through the vessel, the method comprising the steps of:
- gaining access to a surgical site;
- creating a treatment specific hole in one or more vessel walls at the surgical site;
- inserting at least one fastener through the treatment specific hole;
- and
- deploying the fastener within the material matrix at the surgical site.
