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.

22. A sheath for use in implanting an implantable medical device within a living body, comprising:
-
an elongated body having a proximal end and a distal end, and an inner lumen to receive the implantable medical device;
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 (23, 24, 25, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
