MEDICAL DEVICE FIXATION ANCHOR HAVING IMPROVED COMPACTION AND DELIVERY
A medical fixation device having a device attachment portion, a compression bearing portion and a barb portion. The barb portion is separated from a device constraining means by the incorporation of the compression bearing portion.
1 . A method of deploying an implantable medical device, the method comprising:
arranging a constraining sheath at a targeted site, the constraining sheath configured to constrain the implantable medical device and at least two flexible anchors in a constrained configuration and bear against a compression bearings of the at least two anchors to separate barb portions from the constraining sheath; and
advancing the implantable medical device from the constraining sheath to allow the at least two flexible anchors to extend outwardly relative to the implantable medical device and penetrate a tissue at the targeted site with the barb portions of the at least two flexible anchors.
2 . The method of claim 1 , wherein the compression bearing portion is configured to effect separation of the barb portion relative to the exterior surface of the body portion.
3 . The method of claim 1 , wherein the compression bearing portion is configured to deflect the barb portion relative to the exterior surface of the body portion in response to contact with a constraining member.
4 . The method of claim 3 , wherein the compression bearing portion is configured to move the barb portion of the at least anchors inwardly in response to contact with the constraining member.
5 . The method of claim 1 , wherein the barb portion does not contact the exterior surface of the body portion in the constrained configuration.
