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.
Claims87
A composite staple effective for use in an anastomosis, comprising:
- 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;
- wherein each vessel engaging member has two diametrically opposed arms extending out of the binding structure.

A composite staple effective for use in an anastomosis, comprising:
- a plurality of vessel engaging members;
- and
- a bioabsorbable scaffold 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 scaffold being 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 scaffold has resorbed;
- wherein each of the vessel engaging members is at least partially embedded within the scaffold and has at least one arm extending out of the scaffold for effecting an anastomotic connection between a graft vessel and a target vessel, each vessel engaging member having a central body that is larger in diameter than the rest of the member to facilitate anchorage within the scaffold.

A composite staple effective for use in an anastomosis, comprising:
- a plurality of vessel engaging members;
- and
- a radially expandable bioabsorbable scaffold 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 scaffold being 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 scaffold has resorbed;
- wherein each of the vessel engaging members is at least partially embedded within the scaffold and has at least one arm extending out of the scaffold for effecting an anastomotic connection between a graft vessel and a target vessel, each vessel engaging member having a central body that is larger in diameter than the rest of the member to facilitate anchorage within the scaffold.

A composite staple effective for use in an anastomosis, comprising:
- 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 comprising a plurality of bridges and at least one bioabsorbable element, and being 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;
- wherein a pair of adjacent vessel engaging members is connected by at least one bridge, and at least one pair of adjacent vessel engaging members is connected to the at least one bioabsorbable element by bars embedded within the bioabsorbable element.

A composite staple effective for use in an anastomosis, comprising:
- a plurality of vessel engaging members, each vessel engaging member comprising a plurality of protrusions;
- and
- a bioabsorbable scaffold 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 scaffold being 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 scaffold has resorbed;
- wherein each of the vessel engaging members is at least partially embedded within the bioabsorbable scaffold, such that the plurality of protrusions extend beyond an outer surface of the scaffold for effecting an anastomotic connection between a graft vessel and a target vessel.
