Two-part implantable cardiac lead
First Claim
Patent Images
1. A method of implanting a cardiac lead, the method comprising:
- advancing an outer lead portion into a coronary vessel, the outer lead portion having a longitudinal lumen and a terminal connector located at a proximal end, wherein the terminal connector defines an internal bore and is adapted to couple with a cardiac function management device;
advancing a conductive member of an inner lead portion through the longitudinal lumen until it extends beyond a distal end of the outer lead portion, then advancing the pin over the conductive member until a pin mechanically engages with the internal bore of the terminal connector and the pin attaches to a proximal end of the conductive member.

Abstract
Methods of implanting a two-part cardiac lead in a heart are disclosed. The two-part cardiac lead has inner and outer portions and a pin. The inner and outer lead portions are separately advanced to a location of interest within the vasculature of a patient. The pin is attached to a proximal end of the inner lead portion and can provide a connection between the inner and outer lead portions.

10. A method of implanting a cardiac lead, the method comprising:
-
advancing an outer lead portion into a heart or a coronary vessel, the outer lead portion having a longitudinal lumen, a terminal connector located at a proximal end, and a sleeve connected to the terminal connector, wherein the terminal connector defines an internal bore and is adapted to couple with a cardiac function management device; advancing a conductive member of an inner lead portion through the longitudinal lumen; and attaching a pin to a proximal end of the conductive member, such that the pin mechanically engages and couples to the sleeve and is electrically insulated from the terminal connector by the sleeve. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of implanting a cardiac lead, the method comprising:
-
advancing a guide catheter to a desired location in or near a heart; advancing an inner lead portion having a conductive member through the guide catheter; advancing an outer lead portion having a longitudinal lumen and a terminal connector located at a proximal end of the outer lead portion over the inner lead portion, wherein the terminal connector defines an internal bore and is adapted to couple with a cardiac function management device; and attaching a pin to a proximal end of the conductive member, such that the pin mechanically engages and couples to the internal bore of the terminal connector. - View Dependent Claims (17, 18)
