Abstract
A kit for implantation of material into a body, a kit for extraction of tissue from a body and a tissue transplantation kit. A method for implanting material into a body, a method for extracting tissue from a body and a method for transplanting tissue into a body.
Claims9
A tissue transplantation method for extracting tissue from a first site of a body and implanting the extracted tissue into a second site of the body, comprising the steps of:
- opening the skin of the body at the first site of the body, inserting an extraction tube into the opening of the skin;
- thereafter, cutting off the tissue to be extracted at an entrance end of the extraction tube with a cutting member or avulsion member while the extraction tube is present in the body;
- subsequently, removing the extraction tube with the tissue present inside;
- thereafter, placing a penetration rod having a blunt penetration tip in an implantation tube;
- subsequently, making a cavity in the body at a second site with the combination of the penetration rod and a first end of the implantation tube;
- thereafter, removing the penetration rod from the implantation tube;
- thereafter, inserting the extracted tissue to be implanted into a second end of the implantation tube, which tube is disposed in and maintains the made cavity;
- and
- as a last step, removing the implantation tube from the cavity, leaving the tissue to be implanted in the cavity of the body.

A method for transplanting tissue of a body, using a tissue transplantation kit, wherein the tissue transplantation kit comprises:
- an extraction kit comprising an extraction tube having a sharp entrance end, for extraction of tissue and a cutting member or avulsion member for cutting off the tissue to be extracted at the entrance end when the extraction tube is positioned in the body, the extraction tube comprising a container for housing the extracted tissue, and
- an implantation kit comprising an implantation tube, a penetration rod and the container, the penetration rod being blunt in its penetration tip and positionable inside the implantation tube for making a cavity in the body, the implantation tube maintains the made cavity, the container being insertable into the implantation tube when the penetration rod is not present therein,
- the method comprising the steps of:
- opening the skin of the body at a first site of the body, inserting the extraction tube into the opening of the skin;
- thereafter, cutting off the tissue to be extracted at the entrance end of the extraction tube with the cutting member or avulsion member while the extraction tube is present in the body;
- subsequently, removing the extraction tube with the tissue present inside;
- thereafter, placing the penetration rod having the blunt penetration tip in the implantation tube;
- subsequently, making a cavity in the body at a second site of the body with the combination of the penetration rod and a first end of the implantation tube;
- thereafter, removing the penetration rod from the implantation tube;
- thereafter, inserting the extracted tissue to be implanted into a second end of the implantation tube, which tube is disposed in and maintains the made cavity;
- and
- as a last step, removing the implantation tube from the cavity, leaving the tissue to be implanted in the cavity of the body.
