First Claim
Patent Images
1. An intravascular medical device (IVMD) comprising:
- an intravascular housing having a proximal end and a distal end;
a circuit configured to operate the IVMD contained within the housing;
a first lead coupled with the distal end and having a fixation member at a distal end of the lead;
a second lead coupled with the distal end of the housing;
an elongated tether coupled with the proximal end of the housing;
a first tether lumen extending through the tether;
a first housing lumen extending through the housing;
a first lead lumen extending through the first lead; and
a second lead lumen extending through the second lead.

Abstract
An implantable medical device is configured so that all of the major components including a housing and attached leads are disposed within the vasculature of a patient. A tether extends from the housing of the device to an implant location where the tether is secured to tissue outside of the vasculature. In this manner, an intravascular medical device may be implanted at a location remote from final placement, delivered via the vasculature and anchored at the initial entry point.
