A blood vessel dissecting device is disclosed, which includes at least two dissecting devices, which are inserted into a living body along a blood vessel to dissect tissue in a direction of alignment thereof with the blood vessel. The at least two dissecting devices include a first dissecting device and a second dissecting device. The first dissecting device and the second dissecting device are disposed juxtaposedly in the living body, and a branch vessel branched from the blood vessel is located between the first dissecting device and the second dissecting device.

A method and device for perforating an aortic valve to remove excessive calcium deposits on aortic valve leaflets improves the implantation of TAVI replacement valves in patients. By removing excessive calcium deposits, the radial pressure exerted by implanted TAVI replacement valves is reduced, such that there is less blood leakage around the valve and less stress on the cardiac conductive system. A device with a collapsible punch is inserted into the aortic valve. The punch is separable such that the aortic valve leaflets are positioned between at least two elements of the punch. The two elements then compress together with the leaflets between them, causing the aortic valve to be perforated. A circumferential ring of the remaining aortic valve and calcium deposits are left to provide stability for the TAVI replacement valve.

In a tool, a blade head configured to releasably connect to a handle includes a first molded article; and a second molded article that interfaces the first molded article; wherein the second molded article includes: a connector end portion that is integrated within the second molded article so that the connector end portion is seamless; the connector end portion has a channel therein; and the channel is configured to releasably connect about the handle.

A blood vessel dissecting device is disclosed, which includes a dissecting device which, when being inserted into a living body along a blood vessel, dissects tissue in a direction of alignment thereof with the blood vessel, and a cutting device which, when being inserted into the living body along the blood vessel, cuts tissue surrounding the blood vessel in a direction of alignment thereof with the blood vessel. The cutting device includes a main body section which is inserted into the living body and holds the tissue between itself and the dissecting device, and a cutting section which cuts the tissue held between the main body section and the dissecting device.
