A suture for facilitating tying of knots includes a length of suture material fixed to a needle. At least part of the length of the suture material is resiliently biased to a coiled state which is straightenable under applied tension but which returns to its coiled state when released. In use, part of the suture material is drawn through a region of tissue so that portions of the suture material lie on opposite sides of the tissue. A knot is then formed in the suture material by passing one of the portions through at least one resiliently-formed coil formed in the other of the portions, and pulling tight the suture material.

A method of suturing a wound using a length-control technique. The method includes the step of placing a first pass of suture having barbs, with a first pre-attached needle, completely through the skin of the wound, from the undersurface to the outside, at a shallow angle just beyond one apex of the wound. The method also includes the step of placing the opposite end of the suture, with a second pre-attached needle, completely through the skin of the wound, from the undersurface to the outside, at a shallow angle just beyond the opposite apex of the wound. When the skin is pushed down on the suture, the suture pulls both apices towards the center of the wound to connect both apices to each other.

A training kit is provided for practicing aortic valve reconstruction. The aortic valve reconstruction training kit is provided with a blood vessel model and multiple valve leaflet models, and the blood vessel model has a base-capped or base-uncapped cylindrical form having an opening formed on at least the top part thereof. The blood vessel model also has a valve ring part which is formed in the middle of the cylinder and to which the valve leaflet models can be sutured. By using the training kit, it becomes possible to practice a suturing technique that is believed to be the most difficult in aortic valve reconstruction, namely, a technique of accurately suturing a new valve leaflet to a valve ring part, to which an abnormal valve leaflet has been attached, of a cylindrical aorta while viewing the inside of the aorta from above.
