US Patent:

49767100, Dec 11, 1990

Filed:

Nov 15, 1988

Appl. No.:

7/271511

Inventors:

Robert A. Mackin - Phoenix AZ

International Classification:

A61B 1736

US Classification:

606 15

Abstract:

A transparent plastic collapsible balloon is attached to the distal end of a flexible bronchoscope or angioscope. The inflatable balloon has a cavity or "working well" at its distal end which communicates by means of a tube with the central channel of the angioscope. Separate channels of the angioscope allow inflation of the balloon after it has been introduced into a vein or artery and visualization of tissue against which the distal end of the balloon is pressed. A laser fiber, forceps, or other instrument can be passed through the central channel of the angioscope, and through an opening in the distal end of the balloon into the working well cavity to allow lasing or other procedures to be performed on tissue abutted by the balloon and isolated by the working well cavity, and to also allow direct visualization of such procedures. Accurate visualization of the operation of lasing, use of the forceps to obtain biopsies or to remove foreign objects, and other intravascular procedures can thereby be achieved.

International Classification:

A61B 1736

US Classification:

606 15

Abstract:

An angioplasty catheter includes a light source and eyepiece connected by a cable to a proximal portion of a stiff inner catheter of the angioplasty catheter. A plurality of optical fibers carrying light from the light source are attached to or embedded in the stiff inner catheter and terminate just inside an inflatable transparent balloon of the angioplasty catheter to illuminate the interior of the balloon and the walls of an artery, and plaque or other obstruction in the artery. A plurality of optical fibers with distal ends in the proximal portion of the balloon are embedded in or attached to the stiff inner catheter and have proximal ends connected to the eyepiece to enable a physician to view the walls of the artery and the plaque or obstruction before, during, and after an angioplasty procedure.
