ORGAN WALL RETENTION MECHANISM FOR IMPLANTS

摘要

The application provides systems, devices and methods for anchoring implants within the human body, and more specifically to retention means for attaching sensory and other implants in a heart chamber. Displosed is a sensory implant (1000) comprising: (1) an elongated body (1100) enclosing a lumen and a sensory element (1200) disposed therein; (2) a proximal retention member (1400) coupled to said elongated body and comprising a plurality of projections (1420), each of said projections ending with a projection free end; and (3) a distal retention member (1300) positioned distally to said proximal retention member and coupled to said elongated body, said distal retention member comprising a plurality of legs (1320) originating at a distal end of a base portion, each of said legs ending with a leg free end, said distal retention member is self-expandable from a fully closed formation, in which said plurality of legs are substantially straighten and extend axially to said base portion and distally, to a predetermined non-stressed shape, in which said plurality of legs extend laterally to said base portion and proximally, wherein said distal retention member is configured for tissue ingrowth over said plurality of legs. The implant can be a pressure sensing implant and comprise scraping members to move away tissue.

1. A sensory implant comprising:
an elongated body enclosing a lumen and a sensory element disposed therein; a proximal retention member coupled to the elongated body and comprising a plurality of projections, each of the projections ending with a projection free end; and a distal retention member positioned distally to the proximal retention member and coupled to the elongated body, the distal retention member comprising a plurality of legs originating at a distal end of a base portion, each of the legs ending with a leg free end, the proximal retention member and the distal retention member are self-expandable from a fully closed formation, in which the plurality of projections and the plurality of legs extend axially to the base portion to a predetermined non-stressed shape, wherein projection free ends of the projections are configured to move away tissue that interferes with extension or anchoring of the projections.
