Abstract

Apparatus and methods for replacing a heart valve within a vessel. The apparatus includes a replacement heart valve and a plurality of commisure stabilizers connected to the commisures of the heart valve in a removable manner. The commisure stabilizers position and stabilize the commisures in the proper positions as the replacement heart valve is secured within the vessel. The commisure stabilizers may be removed following securement of the replacement heart valve within the vessel. An expansion or retraction device of the invention assists in properly positioning the valve within the vessel.

Claims

1. A method of implanting a replacement heart valve including an annular base and a plurality of commisures extending from spaced apart positions of the annular base, the method comprising:

inserting the replacement heart valve into a patient,

connecting at least one commisure stabilizer to each of the commisures of the replacement heart valve either before or after inserting the replacement heart valve,

leaving a central opening between the commisure stabilizers sufficiently sized to introduce a suturing implement therethrough,

suturing the commisures to the patient by introducing the suturing implement through the central opening and using the commisure stabilizers to orient the commisures of the replacement heart valve, and

removing at least a portion of the commisure stabilizers from the patient leaving the secured replacement heart valve in place within the patient.

2. A method of implanting a replacement heart valve including an annular base and a plurality of commisures extending from spaced apart positions of the annular base, the method comprising:

connecting three commisure stabilizers of a positioning and stabilizing device to the respective three commisures of the replacement heart valve,

inserting the replacement heart valve and the connected commisure stabilizers into a patient,

leaving a central opening between the commisure stabilizers sufficiently sized to introduce a suturing implement therethrough,

suturing the commisures to the patient by introducing the suturing implement through the central opening and using the commisure stabilizers to orient the commisures of the replacement heart valve, and

removing at least a portion of the commisure stabilizers from the patient leaving the secured replacement heart valve in place within the patient.

3. A method of implanting a replacement heart valve including an annular base and a plurality of commisures extending from spaced apart positions of the annular base, the method comprising:

inserting the replacement heart valve into a patient,

connecting at least one commisure stabilizer to each of the commisures of the replacement heart valve either before or after inserting the replacement heart valve,

securing the commisures to the patient while using the commisure stabilizers to orient the commisures of the replacement heart valve, and

removing only a portion of the commisure stabilizers from the patient while leaving a remaining portion thereof and the secured replacement heart valve in place within the patient.
