Abstract
The present disclosure describes methods and apparatus for forming medical devices comprising a stent member and a graft member. Such devices can include graft members that are bonded to the stent member in a selective manner. The selective bonding can allow for greater flexibility, curvature, and conformity of the device within the body of a patient.
Claims66
A stent-graft comprising:
- a stent member;
- a graft member having an inner surface and an outer surface;
- and
- a bonding member, wherein the bonding member fixedly secures a portion of the stent member to a portion of the graft member.
1 more element
A method of making a device comprising:
- providing a substantially tubular mandrel having an outer surface and a longitudinal axis, wherein the mandrel includes a slot extending through the outer surface along the longitudinal axis, and an orientation member disposed within the slot, wherein the orientation member is perpendicularly displaceable within the slot relative to the outer surface of the tubular mandrel;
- displacing the orientation member below the outer surface of the mandrel;
- positioning a graft member over the mandrel;
- positioning a stent member over the mandrel;
- displacing the orientation member above the outer surface of the mandrel;
- and
- orienting the stent member relative to the orientation member.
4 more elements
An article for manufacturing a stent-graft comprising:
- a substantially tubular mandrel comprising an outer surface, a longitudinal axis, a slot, and an orientation member,
- wherein the orientation member is located within the slot and is substantially parallel to the longitudinal axis of the tubular mandrel, and is capable of being perpendicularly displaced relative to the outer surface of the tubular mandrel, and
- wherein the orientation member comprises a plurality of ribs, and wherein the position of each of the plurality of ribs correlates to a desired stent pattern.
A method of making a stent-graft comprising:
- providing a tubular mandrel having an outer surface, at least two forks, and at least one slot;
- positioning a stent member over the outer surface of the mandrel, the stent member having a pattern defining a plurality of apices;
- positioning a graft member over the outer surface of the mandrel;
- applying heat to the portion of the stent member and portion of the graft member located along the at least one slot to form a partially bonded stent-graft;
- and
- removing the partially bonded stent-graft from the mandrel.
3 more elements
An article for manufacturing a stent-graft comprising:
- a tubular mandrel having an outer surface and at least two forks, wherein the outer surface of the at least two forks comprises a grooved section comprising a plurality of grooves.
