Endoluminal Multi-Luminal Surgical Sheath And Method
US Patent:
6328730, Dec 11, 2001
Filed:
Mar 26, 1999
Appl. No.:
9/276679
Inventors:
William W. Harkrider - New Iberia LA
International Classification:
A61M 2500
US Classification:
604523
Abstract:
A radially non-deformable surgical access catheter with a central lumen surrounded by plural peripheral lumens, the lumens being rigidly connected to each other to provide axial stiffness for the catheter as well as rotational stiffness for the catheter so that the catheter may be rotated about its longitudinal axis to place the instruments in any of the peripheral lumens into operational proximity to preselected tissue. Methods are also disclosed.
Endoluminal Knife
US Patent:
2002007, Jun 13, 2002
Filed:
Dec 12, 2000
Appl. No.:
09/733995
Inventors:
William Harkrider - New Iberia LA, US
International Classification:
A61B017/32, A61B017/22
US Classification:
606/159000, 606/172000
Abstract:
A device and method for cutting tissue to a precise depth in which a surgical blade with a rounded cutting edge, including a guard to limit the depth of penetration of the blade, is operatively connected to a handle. The device and method are particularly adapted to an endoluminal knife for cutting only the intima and media layers of a blood vessel wall during a endarterectomy procedure where the non-incised tissue is protected by the guard as the blade passes along the vessel to the point of incision. The angle of the blade may be fixed relative to the handle, or may be controllably varied by a movable cord catheter from an axial, non-contact position for the insertion and removal of the device into the artery to a radial or longitudinal, cutting position once the blade is in the desired location. Once the blade is embedded into the tissue, the device may be rotated by the handle, or by the rotation of the lumen or multilimenal catheter through which the knife has been inserted into the artery.
Endarterectomy Loop
US Patent:
6146397, Nov 14, 2000
Filed:
Apr 6, 1999
Appl. No.:
9/286653
Inventors:
William W. Harkrider - New Iberia LA
International Classification:
A61B 1722
US Classification:
606159
Abstract:
An endarterectomy instrument and method for the treatment of alterosclerosis including a loop and a handle formed from a single strand of wire, the wire of the handle being twisted together to increase the rigidity thereof, but being sufficiently flexible to avoid perforation of the outer layer of the vessel. The angle and shape of the loop may be varied to fit the vessel. In some embodiments, the loop may be compressible to facilitate insertion through a small diameter lumen of a catheter.
