Abstract
A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, at least one elongated portion, first and second end effectors, and a tip. Each end effector is disposed adjacent a distal portion of the at least one elongated portion. Each end effector includes a first jaw member and a second jaw member, and at least one jaw member is movable toward the other jaw member. The tip is disposed in mechanical cooperation with the elongated portion. A distal end of the tip extends distally beyond a distal-most end of the first end effector. The first end effector is movable independently of the tip, and the second end effector is movable independently of the tip.
Claims13
A vein harvesting device, comprising:
- a handle assembly;
- at least one elongated portion extending distally from the handle assembly;
- a first end effector disposed adjacent a distal portion of the at least one elongated portion, the first end effector including a first jaw member and a second jaw member, at least one jaw member movable toward the other jaw member;
- a second end effector disposed adjacent a distal portion of the at least one elongated portion, the second end effector including a first jaw member and a second jaw member, at least one jaw member movable toward the other jaw member;
- and
- a tip disposed in mechanical cooperation with the elongated portion, a distal end of the tip extending distally beyond a distal-most end of the first end effector, wherein the first end effector is movable independently of the tip, and wherein the second end effector is movable independently of the tip.
A method of endoscopically harvesting the saphenous vein and surrounding pedicle, the method comprising:
- using a vein harvesting device including:
- a handle assembly;
- at least one elongated portion extending distally from the handle assembly;
- a first end effector disposed adjacent a distal portion of the at least one elongated portion, the first end effector including a first jaw member and a second jaw member, at least one jaw member movable toward the other jaw member;
- a second end effector disposed adjacent a distal portion of the at least one elongated portion, the second end effector including a first jaw member and a second jaw member, at least one jaw member movable toward the other jaw member;
- and
- a tip disposed in mechanical cooperation with the elongated portion, a distal end of the tip extending distally beyond a distal-most end of the first end effector;
- endoscopically inserting at least a portion of the vein harvesting device adjacent the saphenous vein of a patient;
- bluntly dissecting tissue adjacent the saphenous vein with the tip of the vein harvesting device;
- at least one of sealing and cutting tissue surrounding the pedicle with the first end effector of the vein harvesting device;
- at least one of sealing and cutting tissue surrounding the pedicle with the second end effector of the vein harvesting device;
- and
- removing at least a portion of the saphenous vein and pedicle from the patient.
