Delivery system and method for pulmonary artery leads
First Claim
1. A method of delivering a cardiac lead into a pulmonary artery, the method comprising the steps of:
- providing a delivery device having a distal end adapted for insertion into a venous system, the delivery device including an inflatable balloon positioned near the distal end;
inserting the delivery device at the distal end into the venous system;
inflating the balloon while within the venous system;
floating the balloon and delivery device along a blood flow path within the venous system through a heart and into the pulmonary artery; and
delivering the cardiac lead into the pulmonary artery using the delivery device.

Abstract
A delivery system and method for delivering a pulmonary artery lead into a pulmonary artery includes a delivery device having an inflatable balloon at a distal end. The device is inserted into the venous system, the balloon is inflated and the device is floated along a blood flow path within the venous system through the heart and into the pulmonary artery. The lead is delivered into the pulmonary artery using the device. In one embodiment, the device is a catheter that facilitates placement of an implantation catheter and/or a guide wire into the pulmonary artery for delivery of the lead. In another embodiment, the lead is mounted over the catheter. In yet another embodiment, the delivery device is formed at the distal end of the lead.

14. A delivery system for delivering a cardiac lead into a pulmonary artery, the delivery system comprising:
-
a delivery device having a distal end adapted for insertion into a venous system, the delivery device including an inflatable balloon positioned near the distal end; and
a cardiac lead configured for delivery into the pulmonary artery by use of the delivery device, such that insertion of the delivery device into the venous system and subsequent inflation of the balloon results in floatation of the delivery device along a blood flow path within the venous system through a heart and placement of the delivery device into the pulmonary artery. - View Dependent Claims (15, 16, 17, 18, 19)
