System and method for placing an implantable medical device within a body
First Claim
1. A system for positioning a cardiac lead coupleable with an implantable medical device (IMD) implantable within a living body, the system comprising:
- an elongated body having a lead delivery lumen through which the lead may be deployed and the elongated body withdrawn over the deployed lead;
a flow-directed member coupled to the elongated body; and
a pressure measuring device coupled to the elongated body to obtain pressure measurements so that a location of one or more portions of the elongated body is determinable based upon the pressure measurements and the lead is deployable at the location through the elongated body.

Abstract
A system and method for positioning an implantable medical device (IMD) within a living body is disclosed. The IMD includes a flow-directed member that is deployed within the body to carry the IMD via the flow of blood. The flow-directed member may be an inflatable member such as a balloon, or a mechanical member such as a parachute structure that deploys within the body. The IMD further includes a pressure measuring device and a pressure monitor to obtain pressure measurements at one or more locations within the body adjacent the IMD. The pressure measurements are used to estimate the location of at least a portion of the IMD relative to the body to aid in positioning the IMD in the body without the use of a fluoro-visible media.

14. A sheath for use in implanting a cardiac lead within a living body, comprising:
-
an elongated body having a proximal end and a distal end, and an inner lumen to receive the cardiac lead;
a flow-directed member coupled to the distal end;
a pressure measuring device coupled to the elongated body to measure pressure at one or more predetermined points adjacent the elongated body when the elongated body is located within the living body; and
a pressure monitor coupled to the pressure measuring device to estimate a position of at least a portion of the elongated body relative to the living body. - View Dependent Claims (15, 16, 17)

18. A method of positioning an implantable cardiac lead within a living body, utilizing a lead delivery catheter that includes a flow-directed member and a pressure measuring device, comprising:
-
a.) introducing a portion of the lead delivery catheter into the living body;
b.) deploying the flow-directed member;
c.) utilizing the pressure measuring device to obtain one or more pressure measurements;
d.) utilizing the one or more pressure measurements to position the lead delivery catheter within the living body;
e.) deploying the cardiac lead; and
f.) withdrawing the lead delivery catheter. - View Dependent Claims (19, 20, 21, 22, 23, 24)
