6. A medical device including an anchor having an expanded state and a constrained state, the anchor comprising:
-
a device attachment portion for coupling to a medical device, the device attachment portion having a length and a first longitudinal axis extending along the length of the device attachment portion, a barb portion having a length and a second longitudinal axis extending along the length of the barb portion, and a compression bearing portion positioned between the device attachment portion and the barb portion, wherein in the constrained state, the compression bearing portion has a first apex that is offset relative to the second longitudinal axis and effects a separation between the barb portion and a constraining member, and wherein in the expanded state, the compression bearing portion has a second apex that is offset relative to the second longitudinal axis and the barb portion is adapted to penetrate a vessel. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
