Abstract

An intravascular device includes a shaft having a body defining a major lumen and a plurality of minor lumen. The minor lumens are spaced about the major lumen. The major lumen and the plurality of minor lumen extend from a proximal end of the body to a distal end of the body. One or more wires may extend through the major lumen and/or minor lumen.

Claims

1. An intravascular device, the device comprising:

an elongated body having a proximal end and a distal end, at least part of the elongated body being made of a body material and having a length therebetween;

a major lumen defined by the elongated body and extending from the proximal end to the distal end;

a plurality of minor lumen defined by the elongated body and extending from the proximal end through at least a portion of the length of the elongated body, the minor lumen being fixed relative to the major lumen in transverse cross-section; and

a reinforcement layer connected to the elongated body, the reinforcement layer including a reinforcement material having a greater elastic modulus than the body material.

2. The intravascular device of claim 1, further comprising an outer jacket.

3. The intravascular device of claim 2, wherein the outer jacket includes a first material in a distal region and a second material in a proximal region, the first material having a lower elastic modulus than the second material.

4. The intravascular device of claim 1, further comprising a radiopaque material in a distal portion of the elongated body.

5. The intravascular device of claim 1, wherein the elongated body has a uniform outer diameter along the length from the proximal end to the distal end.

6. The intravascular device of claim 1, wherein the elongated body is a monolithic extruded body.

7. The intravascular device of claim 1, further comprising a compression coil located in the major lumen.

8. The intravascular device of claim 7, wherein the compression coil extends from the proximal end to the distal end.

9. The intravascular device of claim 1, wherein at least two of the plurality of minor lumen are positioned substantially opposite one another relative to the major lumen.

10. An intravascular device, the device comprising:

an elongated body having a proximal end and a distal end, at least part of the elongated body being made of a body material and having a length therebetween;

a major lumen defined by the elongated body and extending from the proximal end to the distal end;

a plurality of minor lumen defined by the elongated body and extending from the proximal end to the distal end of the elongated body, the minor lumen being fixed relative to the major lumen in transverse cross-section; and

a medical device connected to the distal end of the elongated body.

11. The device of claim 10, wherein the medical device is a replacement heart valve.

12. The device of claim 10, further comprising a control wire, the control wire extending through one of the plurality of minor lumen and being operably connected to the medical device.

13. The device of claim 12, wherein applying a longitudinal force upon the control wire imparts a force to the medical device, causing a portion of the medical device to move relative to the distal end of the elongated body.

14. The device of claim 10, further comprising a reinforcement layer connected to the elongated body, the reinforcement layer including a reinforcement material having a greater elastic modulus than the body material.

15. A delivery catheter system, the system comprising:

a shaft including;

an elongated body having a proximal end and a distal end, at least part of the elongated body being made of a body material and having a length therebetween,

a major lumen defined by the elongated body and extending from the proximal end to the distal end,

a plurality of minor lumen defined by the elongated body and extending from the proximal end through at least a portion of the length of the elongated body, the minor lumen being fixed relative to the major lumen in transverse cross-section, and

a reinforcement layer connected to the elongated body, the reinforcement layer including a reinforcement material having a greater elastic modulus than the body material;

a handle operably connected to the proximal end of the elongated body; and

a control wire connected to the handle extending through at least one of the plurality of minor lumen from the proximal end of the elongated body to the distal end of the elongated body.

16. The system of claim 15, further comprising a lining material positioned between at least part of the wire and a surface of the minor lumen through which the wire extends.

17. The system of claim 15, further comprising a medical device connected to the distal end of the shaft.

18. The system of claim 15, wherein the distal end of the shaft includes a radiopaque marker thereon.

19. The system of claim 15, further comprising an outer jacket located on an outer surface of the elongated body and extending along at least a portion of the length of the elongated body.

20. The system of claim 15, wherein the handle is configured to apply a longitudinal force to the wire.
