Claims20
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,
- a 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 adopts a first non-linear configuration and effects a separation between the barb portion and a constraining member, and
- wherein in the expanded state, the compression bearing portion adopts a second non-linear configuration and the barb portion is adapted to penetrate a vessel wall.
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,
- a 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 is curved relative to the barb portion and effects a separation between the barb portion and a constraining member, and
- wherein in the expanded state, the compression bearing portion is curved relative to the barb portion and the barb portion is adapted to penetrate a vessel.
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.
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 protrudes away from 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 protrudes away from the second longitudinal axis and the barb portion is adapted to penetrate a vessel.
