Abstract
A percutaneous harvesting device for the harvesting of tubular body members from a body is disclosed. The percutaneous harvesting device includes an endovascular guide for sufficiently straightening the tubular vessel to be removed and a perivascular cutting tool that is inserted over the endovascular guide. The cutting tool is advanced along the length of the tubular body member to be removed and it cuts body tissue (wherein the tubular body member is positioned inside the body tissue) as it is advanced. The body tissue is thus dissected from the body and can then be extracted percutaneously and rapidly from the body by pulling the endovascular guide, and the tubular body member and surrounding body tissue, from the body.
Claims20
A device for removing a tubular body member from a body, the device comprising a cutting tool that includes:
- (a) a cutting head having (i) a leading edge comprising an annular cutting blade, and (ii) an attachment section;
- and
- (b) a body section having a proximal end, a distal end and an inner passage extending therethrough, the distal end operable to couple to the attachment section of the cutting head.
An apparatus for harvesting a tubular body member, the apparatus comprising:
- (a) an endovascular component having a diameter smaller than the diameter of the tubular body member, the endovascular component capable of being inserted into the tubular body member;
- (b) a cutting tool comprising:
- (i) a tubular body section;
- (ii) a cutting head attached to the tubular body section, the cutting head having a leading edge comprising an annular cutting blade;
- and
- (iii) an opening extending through the cutting tool;
- wherein the opening is sized to allow the tubular body member and some body tissue surrounding the tubular body member to fit inside.
A method for removing a tubular body member from a body, the method comprising the steps of:
- making a first incision;
- accessing and dividing a first end of the tubular body member near the first incision;
- making a second incision;
- accessing and dividing a second end of the tubular body member near the second incision;
- inserting an endovascular component into the first end of the tubular body member;
- moving the endovascular component through the tubular body member and out the second end so that the endovascular component has a proximal end exposed at the first end of the tubular body structure and a distal end exposed at the second end of the tubular body structure;
- securing the proximal end of the endovascular component and the distal end of the endovascular component and straightening the tubular body member by applying force to each end of the endovascular component;
- positioning a cutting tool having a leading edge comprising an annular cutting blade and an inner cavity extending therethrough so that the endovascular component is inside the inner cavity;
- advancing the cutting tool from the first end to the second end, the cutting tool cutting through and dissecting body tissue as it moves, wherein the tubular body portion is positioned within the dissected body tissue;
- and
- removing the dissected body tissue including the tubular body member.
