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 delivery system comprising:

a medical electrical lead that includes a lumen;

a mapping guidelet inserted through the lumen, the mapping guidelet includes

an elongated member that includes first, second, and third coated segments, a proximal uncoated segment, and an active distal segment, at least one of the first, second, and third coated segments comprises hydrolytically stable polyimide;

a programmer coupled to the uncoated segment.

2. The medical delivery system of claim 1 wherein the mapping guidelet solely uses a single elongated member adapted to pass the lead to a coronary vein of a patient.

3. The medical delivery system of claim 1 wherein the mapping guidelet aids in delivery of the lead by simultaneously guiding and electrically mapping potential sites for placement of the lead into a vein or artery of a patient.

4. The medical delivery system of claim 1 wherein one of the first, second and third coated segments comprises one of hydrolytically stable polyimide, polytetrafluorethylene (PTFE), and parlyene.

5. The medical delivery system of claim 1 wherein the mapping guidelet being unipolar in its sensing ability.

6. The medical delivery system of claim 1 wherein the mapping guidelet being bipolar in its sensing ability.

7. The medical delivery system of claim 1 wherein the active distal segment of the mapping guidelet being treated with one of titanium nitride and a platinum black oxide.

8. The medical delivery system of claim 1 wherein the mapping guidelet continuously senses R-waves during movement of the mapping guidelet in at least one coronary vein location.

10. The medical delivery system of claim 1 wherein the mapping guidelet aids in delivery of the lead by simultaneously guiding and electrically mapping potential sites for placement of the lead into a vein or artery of a patient.

11. The medical delivery system of claim 8 wherein one of the first, second and third coated segments comprises one of PTFE, and parlyene.

12. The medical delivery system of claim 8 wherein the mapping guidelet being unipolar in its sensing ability.

13. The medical delivery system of claim 8 wherein the mapping guidelet being bipolar in its sensing ability.

14. The medical delivery system of claim 8 wherein an active distal segment of the mapping guidelet being treated with one of titanium nitride and a platinum black oxide.

9. A medical delivery system adapted for placement of a lead through a coronary vein of a patient comprising:

a medical electrical lead that includes a lumen;

a mapping guidelet inserted through the lumen, the mapping guidelet includes a partially insulated elongated member configured to pass the medical electrical lead through the coronary vein of a patient, the partially insulated elongated member being insulated with hydrolytically stable polyimide,

wherein the mapping guidelet does not require both a stylet and a guidewire for placement of the lead.
