Abstract

An assembly that includes an apparatus having an elongate body and an expandable/collapsible device, a tubular member defining a lumen configured to receive the apparatus, and a handle, fixedly connected to the elongate body and removably connected to the tubular member, configured to move at least one of the elongate body and the tubular member relative to the other.

Claims

1. An assembly, comprising:

an apparatus including an elongate body defining a distal portion and a proximal portion and an expandable/collapsible device carried by the distal portion of the elongate body;

a tubular member defining a distal portion, a proximal portion and a lumen configured to receive the apparatus; and

a handle fixedly connected to one of the proximal portion of the elongate body and the proximal portion of the tubular member and removably connected to the other of the proximal portion of the elongate body and the proximal portion of the tubular member, the handle being configured to move at least one of the elongate body and the tubular member relative to the other of the elongate body and the tubular member.

2. An assembly as claimed in claim 1, wherein the handle is fixedly connected to the proximal portion of the elongate body and removably connected to the proximal portion of the tubular member.

3. An assembly as claimed in claim 2, wherein the handle and tubular member include respective luer fittings.

4. An assembly as claimed in claim 1, wherein the elongate body comprises a catheter body.

5. An assembly as claimed in claim 1, wherein the expandable/collapsible device comprises a basket including a plurality of splines and at least one electrode on each spline.

6. An assembly as claimed in claim 5, further comprising:

an electrical connector mounted on the handle; and

a plurality of wires respectively connecting each of the electrodes to the electrical connector.

7. An assembly as claimed in claim 1, wherein the tubular member comprises a sheath.

8. An assembly as claimed in claim 1, wherein the tubular member includes a pre-bent distal portion.

9. An assembly as claimed in claim 1, wherein the tubular member includes a fluid port.

10. An assembly as claimed in claim 1, wherein the handle comprises a first handle member and a second handle member movable relative to one another.

11. An assembly as claimed in claim 10, wherein the first and second handle members are slidable relative to one another.

13. An assembly as claimed in claim 12, further comprising:

an electrical connector mounted on the first handle member; and

a plurality of wires respectively connecting each of the electrodes to the electrical connector.

15. An apparatus as claimed in claim 14, wherein the handle and tubular member include respective luer fittings.

16. An apparatus as claimed in claim 14, wherein the elongate body comprises a catheter body.

17. An apparatus as claimed in claim 14, wherein the expandable/collapsible device comprises a basket including a plurality of splines and at least one electrode on each spline.

18. An apparatus as claimed in claim 17, further comprising:

an electrical connector mounted on the handle; and

a plurality of wires respectively connecting each of the electrodes to the electrical connector.

19. An assembly as claimed in claim 14, wherein the handle comprises a first handle member and a second handle member movable relative to one another.

20. An assembly as claimed in claim 19, wherein the first and second handle members are slidable relative to one another.

12. An assembly, comprising:

an apparatus including an elongate catheter body defining a distal portion and a proximal portion and an expandable/collapsible basket carried by the distal portion of the catheter elongate body and having a plurality of splines and a plurality of electrodes supported on each spline;

a tubular member defining a distal portion, a proximal portion and a lumen configured to receive the apparatus, the proximal portion of the tubular member including a first mechanical fitting; and

a handle including first and second handle members that are slidable relative to one another, the first handle member being fixedly connected to the proximal portion of the elongate catheter body and the second handle member including a second mechanical fitting configured to be removably connected to the first mechanical fitting thereby removably connecting the tubular member to the second handle member.

14. An apparatus for use with a tubular member defining a distal portion, a proximal portion and a lumen and including a first connector carried by the distal portion of the tubular member, the apparatus comprising:

an elongate body defining a distal portion and a proximal portion;

an expandable/collapsible device carried by the distal portion of the elongate body; and

a handle fixedly connected to the proximal portion of the elongate body and including a second connector configured to removably connect to the first connector carried by the proximal portion of the tubular member, the being handle configured to move at least one of the elongate body and the tubular member relative to the other of the elongate body and the tubular member when the first and second connectors are removably connected to one another.

21. An electrophysiological procedure kit, comprising:

first and second tubular members defining a distal portion, a proximal portion and a predetermined characteristic, the predetermined characteristic of the first tubular member being different than the predetermined characteristic of the second tubular member; and
