ADJUSTABLE GUIDEWIRE RECEIVING MEMBER
An intravascular device delivery system has an elongated member with an outer sleeve and a distal cap longitudinally fixed to a guidewire receiving member. The guidewire receiving member is moveable longitudinally relative to the outer sleeve to move the distal cap relative to the outer sleeve.
1 . An intravascular device delivery system, the system comprising:
an elongated member with a proximal end, a distal end, and a longitudinal axis therebetween, the elongated member including:
an outer sleeve extending from the proximal end to the distal end,
a guidewire receiving member extending from the proximal end to the distal end, and
a distal cap longitudinally fixed to the guidewire receiving member and configured to engage with a distal end of the outer sleeve.
2 . The system of claim 1 , further comprising a handle connected to the proximal end of the guidewire receiving member.
3 . The system of claim 2 , wherein the handle includes a proximal end plate that is longitudinally moveable relative to a body of the handle.
4 . The system of claim 3 , wherein the proximal end plate is selectively fixable longitudinally relative to the body of the handle.
5 . The system of claim 4 , wherein the guidewire receiving member is selectively fixed to the proximal end plate.
6 . The system of claim 1 , wherein the distal cap has a proximal taper.
7 . The system of claim 1 , wherein the proximal taper comprises a thread.
8 . The system of claim 1 , wherein the guidewire receiving member is a cable tube.
9 . The system of claim 1 , further comprising a guidewire having one or more torque transmission features protruding in a transverse direction from a longitudinal axis of the guidewire.
10 . The system of claim 9 , wherein the distal cap comprises complementary receiving recesses.
11 . The system of claim 1 , wherein the distal cap and the outer sleeve comprise complementary mechanical connection features.
12 . The system of claim 11 , wherein the complementary mechanical connection features comprises complementary threads on the distal cap and the outer sleeve.
13 . The system of claim 11 , wherein the complementary mechanical connection features comprises complementary pins and slots.
14 . The system of claim 11 , wherein the complementary mechanical connection features comprises snap-fit locking features.
15 . The system of claim 1 , wherein the distal cap comprises a distal cap end portion and a distal cap ring, the distal cap end portion being received by the distal cap ring coupled to the guidewire receiving member.
16 . The system of claim 15 , wherein the guidewire receiving member comprises a cut pattern.
17 . The system of claim 1 , wherein the distal cap comprises a proximal tapered end and a distal tapered end.
18 . The system of claim 1 , wherein the distal cap comprises a distal cap end portion and a distal cap proximal portion, the distal cap end portion mechanically engaging with a locking ring selectively mounted to the guidewire receiving member.
19 . The system of claim 18 , wherein the locking ring slidable cooperates with the guidewire receiving member.
20 . The system of claim 18 , further comprises complementary recess in one of the distal cap end portion and the distal cap proximal portion and a protrusion in the other of the distal cap end portion and the distal cap proximal portion.
21 . The system of claim 20 , further comprising a fixing material to attach the distal cap end portion and the distal cap proximal portion to the guidewire receiving member.
