Devices and methods for positioning and anchoring implantable sensor devices
First Claim
1. An anchoring system for anchoring an implantable medical device (IMD) in a bodily vessel of a patient, the anchoring system comprising:
- an anchoring structure adapted to be secured in the bodily vessel;
an attachment structure integrated with the anchoring structure, the attachment structure enabling attachment of the IMD to the anchoring structure; and
a positioning mechanism operable to position the anchoring structure at a desired location in the bodily vessel.

Abstract
Methods and systems provide for anchoring implantable medical device inside a bodily vessel. An anchoring structure can include a stent-like structure to which the IMD is attached. The stent-like structure is positioned at a desired location in the bodily vessel. The stent-like structure can be repositioned based on a measurement from the IMD. The IMD can include outwardly extending fins over which tissue can fibrose to affix the IMD to a wall of the bodily vessel. The stent-like structure can be made of a bio-absorbable material. The IMD can be attached to a stent-like structure by leads, by being lodged in a recessed diaphragm, by being embedded in mesh of the stent-like structure, or other methods. The stent-like structure can be balloon deployable to allow for controlled positioning and anchoring. The anchoring structure can include a vena cava filter.

15. A method for anchoring an implantable medical device in a bodily vessel, the IMD operable to measure a physiologic parameter within the bodily vessel, the method comprising:
-
attaching a first implantable medical device (IMD) to a stent-like structure, wherein attaching comprises securing at least a portion of the IMD in a structure integrated with the stent-like structure;
positioning the stent-like structure at a desired location within the bodily vessel; and
anchoring the stent-like structure at the desired location within the bodily vessel. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A method for anchoring an implantable medical device (IMD), comprising:
-
connecting a collapsible stent to an IMD operable to measure a physiologic parameter;
inserting a deflated balloon through the stent with the stent collapsed;
positioning the stent with the balloon and the IMD inside a bodily vessel;
while positioning the stent, obtaining measurements from the IMD;
at least partially inflating the balloon; and
selecting a location in the bodily vessel at which to secure the stent based on the obtained measurements. - View Dependent Claims (25, 26, 27)
