Abstract
An implant delivery system is described, having a distal tip and outer sheath that remain in a fixed position during implant delivery. A pusher mechanism within the sheath pushes an implant out of a gap between a distal end of the sheath and the distal tip.
Claims15
A vascular prosthesis delivery device comprising:
- an inner tube accommodating a guidewire;
- a prosthesis;
- a pusher element movable over the inner tube, the pusher element accommodating a proximal portion of the prosthesis;
- a tip member movable over the inner tube and having an interior passage, the tip member accommodating a distal portion of the prosthesis;
- and,
- a distal enlargement positioned at a distalmost end of the inner tube;
- wherein the passage of the tip member is configured to at least partially, distally pass over the distal enlargement and to limit further distal movement of the tip member during prosthesis delivery.

A vascular prosthesis delivery device comprising:
- an inner tube accommodating a guidewire;
- a prosthesis;
- a pusher element movable over the inner tube, the pusher element accommodating a proximal portion of the prosthesis;
- a tip member movable over the inner tube, the tip member accommodating a distal portion of the prosthesis;
- and
- a distal enlargement located near a distal end of the inner tube;
- wherein the tip member has a passage having a smaller inner diameter section and a larger inner diameter section, such that the larger inner diameter section is configured to distally move over the distal enlargement and the smaller inner diameter section is configured to limit further distal movement of the tip member during prosthesis delivery.

A vascular prosthesis delivery device comprising:
- an inner tube accommodating a guidewire;
- a prosthesis;
- a pusher element movable over the inner tube, the pusher element having recesses accommodating a proximal portion of the prosthesis;
- a sheath disposed over the inner tube and the pusher element;
- a tip member movable over the inner tube, the tip member having an inner passage and recesses accommodating a distal portion of the prosthesis;
- and
- a stop member positioned at a distalmost end of the inner tube and having a diameter larger than the inner tube;
- wherein the stop member is configured to pass at least partially within and engage the inner passage of the tip member to limit further movement of the tip member during prosthesis delivery from the sheath.
