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. |
