Abstract
A device for delivering a prosthesis to a damaged body vessel includes first and second generally elongated members joined to each other along a length thereof. A distal end of each of the elongated members is insertable through an outer layer of skin to access the vessel. The distal ends are cooperatively maneuverable between a closed position for retaining the prosthesis during delivery to the vessel and an open position for releasing the prosthesis upon delivery. Each of the elongated members has a prosthesis retaining member disposed at a distal tip. The retaining members are configured for retaining the prosthesis in a constricted condition when the distal ends are in the closed condition for delivery of the prosthesis to the damaged vessel.
Claims11
A device for delivering a prosthesis to a damaged body vessel, the prosthesis of a type having a constricted condition for delivery to said damaged body vessel and an expanded condition upon deployment at the damaged vessel, the device comprising:
- first and second generally elongated members joined to each other along a respective length thereof, each of the elongated members having a proximal end accessible to an operator during use of said device, a distal end for insertion through a body opening from an outer layer of skin to access said damaged body vessel, and a pivot point intermediate said proximal and distal end along said length for joinder to the other elongated member, each of said distal ends extending to a distal tip, said elongated members arranged along said pivot point such that said distal ends are cooperatively maneuverable between a closed position for retaining the prosthesis during a delivery to said damaged body vessel and an open position for releasing the prosthesis upon said delivery;
- the first elongated member having a first prosthesis retaining member disposed at said first elongated member distal tip, and the second elongated member having a second prosthesis retaining member disposed at said second elongated member distal tip;
- said first and second prosthesis retaining members configured for retaining said prosthesis therebetween in said constricted condition when said distal ends are in said closed condition for delivery of said prosthesis at said damaged vessel.
6-15. (canceled)
A method for open surgical repair of a damaged portion of a body vessel, comprising:
- positioning a device having a prosthesis assembly loaded therein for delivery to said damaged vessel portion through an open air pathway, the device comprising first and second generally elongated members, each generally elongated member having a proximal end accessible to an operator, a distal end for insertion to said damaged vessel portion, and being joined to the other elongated member along a length thereof, each of the distal ends extending to a distal tip;
- said first elongated member having a first prosthesis retaining member disposed at said first elongated member distal tip, and said second elongated member having a second prosthesis retaining member disposed at said second elongated member distal tip, said elongated members arranged such that said distal ends are cooperatively maneuverable between a closed position having said prosthesis assembly loaded therein, and an open position;
- the prosthesis assembly comprising a prosthesis having first and second ends, and respective first and second sheaths configured for maintaining said first and second prosthesis ends in a constricted condition, each of said first and second sheaths including a tab member for selectively splitting said sheath;
- passing said distal ends of said device through said open air pathway to said damaged vessel portion with said distal ends in said closed position;
- maneuvering said distal ends such that said first sheath and said first constricted prosthesis end are inserted into a first side of said damaged vessel portion;
- maneuvering said distal ends such that said second sheath and said second constricted prosthesis end are inserted into a second side of said damaged vessel portion;
- pulling said first sheath tab member for splitting said first sheath, wherein said first prosthesis end expands to engage an inner surface of said first side of said damaged vessel portion;
- and
- pulling said second sheath tab member for splitting said second sheath, wherein said second prosthesis end expands to engage an inner surface of said second side of said damaged vessel portion.
