Abstract

The medical lead delivery device more easily and quickly delivers a lead to or through the coronary vein of a patient'"'"'s heart. The medical lead delivery device includes an elongated body, a controller, a first and second spring, and a sleeve. The elongated body includes a proximal end and a distal end. The controller is disposed at the proximal end and provides enhanced control of the distal tip of the elongated body.

Claims

1. A medical lead delivery device comprising:

an elongated body extending from a proximal end to a distal end; and

a slideable controller comprising a proximal end and a distal end, wherein the slideable controller defines a channel extending from the proximal end to the distal end configured to receive the elongated body, wherein the slideable controller is slideably adjustable along a length of the elongated body, wherein the slideable controller is configurable between an engaged position and a disengaged position, wherein the elongated body is clamped in the channel of the slideable controller when the elongated body is located in the channel and the slideable controller is in the engaged position, wherein the elongated body is released when the slideable controller is in the disengaged position, and further wherein the slideable controller is removable from the elongated body.

2. The medical lead delivery device of claim 1, wherein the slideable controller is configured to provide increased control over the distal end of the elongated body.

3. The medical lead delivery device of claim 1, wherein the slideable controller further comprises a body and a lever movably coupled to the body.

4. The medical lead delivery device of claim 3, wherein the lever is movable to clamp down on the elongated body when the slideable controller is in the engaged position.

5. The medical lead delivery device of claim 3, wherein the lever is movable to release the elongated body when the slideable controller is in the disengaged position.

6. The medical lead delivery device of claim 3, wherein the elongated body is clamped in the channel between the body and the lever of the slideable controller using an interference fit when the slideable controller is in the engaged position.

7. The medical lead delivery device of claim 3, wherein the slideable controller further comprises a pin coupling the lever to the body such that the lever is pivotally moveable about an axis defined by the pin between the engaged position and the disengaged position.

8. The medical lead delivery device of claim 1, wherein the elongated body is clamped in the channel of the slideable controller using an interference fit along a length of the elongated body when the slideable controller is in the engaged position.

9. The medical lead delivery device of claim 1, wherein the elongated body comprises conductive material, wherein the medical lead delivery device further comprises at least one coil extending from a proximal end to a distal end and surrounding at least a portion of the elongated body, wherein the distal end of the at least one coil is located closer than the proximal end of the at least one coil to the distal end of the elongated body, wherein the proximal end of the at least one coil is coupled to the elongated body.

10. The medical lead delivery device of claim 1, wherein the medical lead delivery device further comprises an insulative material surrounding at least a portion of the elongated body.

11. The medical lead delivery device of claim 1, wherein one of the distal end and the proximal end of the slideable controller comprises a tapered exterior surface extending inward towards the channel.

12. The medical lead delivery device of claim 1, wherein one of the distal end and the proximal end of the slideable controller comprises a tapered interior surface extending inward towards the channel.

13. A medical lead delivery device comprising:

an elongated body extending from a proximal end to a distal end, wherein the elongated body comprises conductive material;

at least one coil extending from a proximal end to a distal end and surrounding at least a portion of the elongated body, wherein the distal end of the at least one coil is located closer than the proximal end of the at least one coil to the distal end of the elongated body, wherein the proximal end of the at least one coil is coupled to the elongated body; and

a slideable controller slideably adjustable along a length of the elongated body, wherein the slideable controller is configurable between an engaged position and a disengaged position, wherein the elongated body is clamped in the slideable controller when the slideable controller is in the engaged position, and further wherein the elongated body is released when the slideable controller is in the disengaged position.

14. The medical lead delivery device of claim 13, wherein the slideable controller further comprises a body and a lever movably coupled to the body.

15. The medical lead delivery device of claim 14, wherein the lever is movable to release the elongated body when the slideable controller is in the disengaged position.

16. The medical lead delivery device of claim 14, wherein the elongated body is clamped between the body and the lever of the slideable controller using an interference fit when the slideable controller is in the engaged position.

17. The medical lead delivery device of claim 13, wherein the elongated body is clamped in the slideable controller using an interference fit when the slideable controller is in the engaged position.

18. The medical lead delivery device of claim 13, wherein the medical lead delivery device further comprises an insulative material surrounding at least a portion of the elongated body.

19. The medical lead delivery device of claim 13, wherein the slideable controller comprises a proximal end and a distal end, wherein the slideable controller defines a channel extending from the proximal end to the distal end configured to receive the elongated body, and further wherein one of the distal end and the proximal end of the slideable controller comprises a tapered interior surface extending inward towards the channel.
