Insert for distal end cap
An intravascular device delivery system has an elongated member, a guidewire receiving member, and a distal cap longitudinally fixed to a guidewire receiving member. The distal cap includes an insert having an elongate member, a rim member radially separated from the elongate member, and a wall member supporting the rim member, the wall member being disposed between the rim member and the elongate member.
1. An insert for a distal cap of an intravascular delivery device for a prosthetic heart valve, the insert comprising:
an elongate member comprising a lumen and a port;
a rim member radially separated from the elongate member, wherein a perimeter of the rim includes a circumferential groove;
a wall member supporting the rim member, the wall member disposed between the rim member and the elongate member;
a radiopaque marker received within the circumferential groove, the radiopaque marker being one of: a band, or a ring;
a guidewire receiving member extending through the lumen of the elongate member and extending both proximally and distally relative to the elongate member;
wherein the distal cap includes a molded portion configured to fully encase an outer surface of the insert and the radiopaque marker that are embedded within the distal cap.
2. The insert as recited in claim 1 , wherein the wall member comprises a plurality of holes.
3. The insert as recited in claim 1 , wherein the guidewire receiving member comprises a proximal section and a distal section, and wherein the distal section has greater flexibility than the proximal section.
4. The insert as recited in claim 3 , wherein the proximal section and the distal section are separate pieces adjoined to one another within the lumen of the elongate member.
5. The insert as recited in claim 1 , wherein the port is defined by a through-hole within at least one wall of the elongate member.
6. The insert as recited in claim 5 , wherein the port is positioned in a longitudinally central region of the elongate member and provides access to the lumen, the port being configured to receive glue or adhesive for bonding the insert and the guidewire receiving member.
7. 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:
a guidewire receiving member extending from the proximal end to the distal end,
an insert having (i) an elongate member comprising a lumen and a port, (ii) a rim member radially separated from the elongate member, wherein a perimeter of the rim includes a circumferential groove, and (iii) a wall member supporting the rim member, the wall member disposed between the rim member and the elongate member,
a radiopaque marker received within the circumferential groove, the radiopaque marker being one of: a band, or a ring,
a distal cap longitudinally fixed to the guidewire receiving member, the distal cap comprising a molded portion that fully encases an outer surface of the insert and the radiopaque marker such that the insert and the radiopaque marker are embedded within the distal cap.
8. The system of claim 7 , wherein the insert is adhesively bonded to the guidewire receiving member.
9. The system of claim 8 , wherein the insert comprises a plurality of spoke-like members extending between an elongate member of the insert and a rim member of the insert.
10. The system of claim 9 , wherein each of the plurality of spoke-like members is tapered.
11. The system of claim 7 , wherein the insert comprises a plurality of through-holes extending along a longitudinal axis of the guidewire receiving member.
12. The system of claim 7 , wherein the distal cap comprises one or more echogenic features that allow visualization under echocardiography techniques.
13. The system of claim 12 , wherein the one or more echogenic features include pores of a porous material or one or more chambers within the distal cap.
14. The system of claim 7 , wherein the guidewire receiving member comprises a proximal section and a distal section, and wherein the distal section has greater flexibility than the proximal section.
15. The system of claim 14 , wherein the proximal section and the distal section are separate pieces adjoined to one another within the lumen of the elongate member.
16. The system of claim 7 , wherein the insert is embedded within the distal cap such that a plane defined by a rim of the insert is substantially perpendicular with respect to a longitudinal axis of the distal cap.
17. The system of claim 7 , wherein the guidewire receiving member extends both proximally and distally relative to the elongate member.
18. 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:
a guidewire receiving member extending from the proximal end to the distal end, and a distal cap longitudinally fixed to the guidewire receiving member, the distal cap comprising an insert mounted to the guidewire receiving member and supporting a radiopaque marker, wherein the guidewire receiving member comprises a proximal section and a distal section, and wherein the distal section has greater flexibility than the proximal section.
