Abstract
Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exclusion device for an anatomical structure may include a first beam, a second beam, and/or at least one spring operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam and bias the first beam and the second beam in a closing direction. The spring may be operatively coupled to the first beam by a crimp connection.
Claims39
An exclusion device for an anatomical structure, the exclusion device comprising:
- a first beam including a longitudinal cavity;
- a second beam;
- and
- at least one spring received within the longitudinal cavity and operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam and bias the first beam and the second beam in a closing direction;
- wherein the at least one spring is operatively coupled to the first beam by a first crimp connection;
- wherein the first beam is configured to prevent rotation of the at least one spring with respect to the first beam;
- wherein the at least one spring is generally U-shaped and comprises a first end portion and a second end portion generally opposite from a connecting portion;
- wherein the longitudinal cavity receives the first end portion of the at least one spring;
- wherein the first beam comprises an outer wall generally opposite a clamping surface, the clamping surface generally facing the second beam;
- wherein the outer wall comprises an outwardly facing recess proximate the longitudinal cavity;
- and
- wherein the outwardly facing recess is configured to receive a tool therein for crimping the first beam and the at least one spring.
An exclusion device for an anatomical structure, the exclusion device comprising:
- a first beam;
- a second beam;
- and
- at least one spring operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam and bias the first beam and the second beam in a closing direction;
- wherein the at least one spring is operatively coupled to the first beam by a first crimp connection;
- wherein the at least one spring is generally U-shaped and comprises a first end portion and a second end portion generally opposite from a connecting portion;
- wherein the first beam comprises a spring cavity receiving the first end portion of the at least one spring;
- wherein the first beam comprises an outer wall generally opposite a clamping surface, the clamping surface generally facing the second beam;
- wherein the outer wall comprises an outwardly facing recess proximate the spring cavity;
- wherein the outwardly facing recess is configured to receive a tool therein for crimping the first beam and the at least one spring.
An exclusion device for an anatomical structure, the exclusion device comprising:
- a first beam including a longitudinal cavity intersected by a transverse hole;
- a second beam;
- and
- at least one spring operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam and bias the first beam and the second beam in a closing direction;
- wherein the at least one spring is operatively coupled to the first beam by a friction fit proximate the transverse hole;
- wherein the first beam is configured to inhibit rotation of the at least one spring with respect to the first beam.
