Patent number: 6725081Abstract: A device and method for precisely delivering dosage of radiation from a radiation source to a treatment site of a vessel is provided herein. In one embodiment, the device includes a catheter which inserts into a vessel lumen of the body. The catheter includes an adjuster section for altering a portion of the radiation emitting radially from the radiation source so that the radiation source delivers an asymmetrical radiation profile to the vessel. The device can also include a catheter supporter which inhibits rotational deformation in the catheter between a catheter distal end and a catheter proximal end. This allows the delivery section to be precisely rotated to properly position the adjuster section within the vessel lumen.Type: GrantFiled: June 6, 2001Date of Patent: April 20, 2004Assignees: Volcano Therapeutics, Inc., The Cleveland Clinic FoundationInventors: Jay P. Ciezki, Eugene J. Jung, Jr., Eric J. Lee, Emin M. Tuzcu, James D. Savage, Martin S. Weinhous

Patent number: 6626816Abstract: A delivery device and method for delivering a dosage of radiation from a radiation source to a treatment site of a vessel is provided herein. The delivery device includes a catheter and a delivery area. The catheter is suitable for being inserted into a vessel lumen of the vessel and includes a delivery lumen for receiving the radiation source. The delivery area also receives the radiation source. The delivery area includes an attenuator section for attenuating a portion of the radiation emitting from the radioactive area so that the delivery area emits an eccentric radiation profile. The delivery device can also include a catheter supporter which inhibits rotational deformation in the catheter between a catheter distal end and a catheter proximal end. This allows the delivery area to be precisely rotated to properly position the attenuator section within the vessel lumen.Type: GrantFiled: July 12, 2000Date of Patent: September 30, 2003Assignees: Jomed Inc., The Cleveland Clinic FoundationInventors: Jay P. Ciezki, Eugene J. Jung, Jr.

Patent number: 6494835Abstract: A method for providing intravascular brachytherapy includes the step of positioning a radiation source within a target area to be radiation and orienting the attenuator found on the catheter. Once the attenuator or shield is properly oriented, a reference or normalization point or marker (508) is selected. This reference marker (508) can placed, as one example, on the external elastic lamina closest to catheter (100) and can serve as a reference point for the brachytherapy treatment. Several other points of interest can be is selected (504, 506, 510) on the image (500) or images that have been gathered of the treatment site, with dosage levels (512, 522, 520 and 518) being display automatically on the display (406) close to the IVUS image (500).Type: GrantFiled: February 16, 2000Date of Patent: December 17, 2002Assignees: Jomed Inc., Cleveland Clinic FoundationInventors: Jay P.
