Composite Staple for Completing an Anastomosis
First Claim
1. A method of performing a procedure on a vessel having a previously made opening, the method comprising:
- providing a composite staple having a plurality of vessel engaging members and a binding structure holding each of the plurality of vessel engaging members in a predefined spatial relationship with respect to each of the other vessel engaging members, the binding structure including at least one bioabsorbable element configured such that at least one vessel engaging member is free to move with respect to at least one other vessel engaging member after the bioabsorbable element has resorbed, and wherein each vessel engaging member has two diametrically opposed arms extending out of the binding structure;
positioning at least one vessel engaging member at a location proximate the opening;
holding a distal portion of the at least one vessel engaging member in a first configuration;
penetrating the distal portion of the at least one vessel engaging member into tissue adjacent the opening; and
permitting the distal portion of the at least one vessel engaging member to move to a second configuration to close the opening.

Abstract
An anastomosis staple comprising of a plurality of vessel engaging members and a binding structure holding the vessel engaging members together is described. The binding structure has at least one bioabsorbable element. The binding structure is rigid enough to allow for deployment and quickly resorbs to avoid problems associated with intimal hyperplasia and physical hindrance of secondary interventional procedures. The vessel engaging members may be comprised of superelastic or shape memory metal and are independent from one another. The members may be equidistant from one another and embedded within the binding structure. The composite staple can preferably serve as a drug delivery vehicle.
