Medical device fixation anchors
First Claim
1. An implantable medical device, comprising:
- a frame comprising at least one elongate member; and
a fixation member comprising a first cuff, a second cuff, at least a first tissue engagement member configured to anchor to tissue at an implant site to thereby hold the implantable medical device in a position at the implant site, and a cuff joining member comprising an arcuate shape and connected at a first end to the first cuff and at a second end to the second cuff;
wherein the first cuff substantially surrounds a perimeter of a first portion of the at least one elongate member, the second cuff substantially surrounds a perimeter of a second portion of the at least one elongate member, and the cuff joining member does not substantially surround a perimeter of any portion of the at least one elongate member,and wherein the first and second cuffs each have a slip-fit relation with the at least one elongate member to allow for relative movement between the fixation member and the at least one elongate member in response to a bending of the at least one elongate member.

Abstract
An implantable medical device includes a frame that includes at least one elongate member. The implantable medical device also includes a fixation member that has a first cuff, a second cuff, a tissue engagement member configured to anchor to tissue at an implant site to thereby hold the implantable medical device in a position at the implant site, and a cuff joining member that has an arcuate shape and that is connected at a first end to the first cuff and at a second end to the second cuff. The first cuff substantially surrounds a perimeter of a first portion of the at least one elongate member, the second cuff substantially surrounds a perimeter of a second portion of the at least one elongate member, and the cuff joining member does not substantially surround a perimeter of any portion of the at least one elongate member.

23. An implantable medical device, comprising:
-
a frame comprising at least one elongate member; and a fixation member comprising a first cuff, a second cuff, a tissue engagement member configured to anchor to tissue at an implant site to thereby hold the implantable medical device in a position at the implant site, and an elongate joining member comprising a proximal end and a distal end, the elongate joining member connected at the proximal end to the first cuff and at the distal end to the second cuff, the elongate joining member further defining an arcuate shape between the proximal end and the distal end; wherein the first cuff substantially surrounds a perimeter of a first portion of the at least one elongate member, the second cuff substantially surrounds a perimeter of a second portion of the at least one elongate member, and the elongate joining member does not substantially surround a perimeter of any portion of the at least one elongate member, and wherein the first and second cuffs have a slip-fit relation with the at least one elongate member to allow for relative movement between the fixation member and the at least one elongate member in response to a bending of the at least one elongate member.

24. An implantable medical device, comprising:
-
a frame comprising at least one elongate member; and a fixation member comprising a first tubular member, a second tubular member, a tissue engagement member configured to anchor to tissue at an implant site to thereby hold the implantable medical device in a position at the implant site, and an elongate joining member comprising a proximal end and a distal end, the elongate joining member connected at the proximal end to the first tubular member and at the distal end to the second tubular member, the elongate joining member further defining an arcuate shape between the proximal end and the distal end; wherein the first tubular member substantially circumferentially surrounds a first portion of the at least one elongate member, the second tubular member substantially circumferentially surrounds a second portion of the at least one elongate member, and the elongate joining member does not substantially circumferentially surround any portion of the at least one elongate member, and wherein the first and second tubular members have a slip-fit relation with the at least one elongate member to allow for relative movement between the fixation member and the at least one elongate member in response to a bending of the at least one elongate member.
