The cylindrical section can include a marking element configured to mark tissue at fixed positions relative to the cylindrical section. Marking can be performed with a variety of techniques.
Claims38
A tissue marking device comprising:
- a) a generally cylindrical section having a diameter approximately equal to the diameter of an aortic heart valve prosthesis, the cylindrical section comprising a marking element configured to mark tissue at fixed positions relative to the cylindrical section;
- and
- b) a handle attached to the cylindrical section.
A tissue marking device comprising:
- a) a generally cylindrical section having a diameter approximately equal to the diameter of an aortic heart valve prosthesis;
- b) a handle attached to the cylindrical section;
- and
- c) a marker having a marking tip that interfaces with the cylindrical section, wherein the marker is separately positionable from the cylindrical section.
A method for guiding the attachment of an aortic heart valve prosthesis, the method comprising marking the aortic tissue to guide the positioning of the prosthesis and the placement of suture.
A sizer comprising a prosthesis template and a handle extending from the a prosthesis template, the prosthesis template comprising a generally cylindrical section and a plurality of posts along the top edge extending upwardly from the generally cylindrical section around the circumference of the cylindrical section.
