Stent Delivery Catheter With Bumpers For Improved Retention Of Balloon Expandable Stents
US Patent:
6468299, Oct 22, 2002
Filed:
Jun 7, 2001
Appl. No.:
09/878061
Inventors:
Richard S. Stack - Chapel Hill NC
Denise Ching - San Jose CA
Denise Ching - San Jose CA
Assignee:
Advanced Cardiovascular Systems, Inc. - Santa Clara CA
International Classification:
A61F 206
US Classification:
623 111
Abstract:
An improved balloon catheter which includes bumpers located adjacent to the proximal and distal ends of the catheter balloon. The bumpers form a recessed pocket into which a stent crimped onto the catheter balloon is mounted. The recessed pocket formed by the bumpers securely retains the stent on the balloon and minimizes undesired contact between the stent and arterial walls and lesions during advancement of the stent within a patients vasculature.

International Classification:
A61M029/00
US Classification:
606200000
Abstract:
A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which can be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, is capable of enabling at least one operator to control the delivery and removal of an embolic protection device to a position in a patient's vasculature distal to an interventional procedure site, to enable the exchange of the delivery and recovery system. The system, in another embodiment thereof, includes a delivery system and a recovery system which are capable of enabling the delivery and recovery of an embolic protection device so as to maintain a clinically acceptable profile and flexibility through the patient's vasculature.
Guidewire With Variable Coil Configuration
US Patent:
6139511, Oct 31, 2000
Filed:
Jun 29, 1998

William J. Boyle - Temecula CA
Richard S. Stack - Chapel Hill NC
Assignee:
Advanced Cardiovascular Systems, Inc. - Santa Clara CA
International Classification:
A61B 500
US Classification:
600585
Abstract:
The present invention is directed to a guidewire having an elongate core member with a proximal section and a distal section. The distal section has at least one tapered segment, wherein the elongate core member tapers distally to a reduced diameter. Preferably, the tapered segments of the distal section of the elongate core member are marked with radiopaque markers to indicate where a tapered segment begins or ends. A proximal coil having a rectangular cross section and at least one distal coil having a round cross section are disposed around at least a portion of the distal section of the elongate core member. The proximal end of the proximal coil is attached to the distal section of the elongate core member. The distal coils can be made of a material that is radiopaque or non-radiopaque. If one of the distal coils is radiopaque, it may be made from a radiopaque material or it may be made of a hollow tube of non-radiopaque material that is filled with material that is at least partially radiopaque.
Bioabsorbable Stent And Method Of Making The Same
US Patent:

James H. McElhaney - Durham NC
Assignee:
Duke University - Durham NC
International Classification:
A61M 2900
US Classification:
606198
Abstract:
A bioabsorbable stent for placement at the locus of a stenotic portion of a body passage, such as a blood vessel, which is flexible and compliant for safe and effective delivery to the site of the stenotic portion of, for example, a blood vessel, and so as to avoid the disadvantages of chronic implantation, such as arterial rupture or aneurism formation while exposed to the continuous stresses of a beating heart. The stent is formed from a bioabsorbable material and is porous or has apertures defined there through to facilitate tissue ingrowth and encapsulation of the stent. The stent is encapsulated and biodegrades or bioabsorbs within a period of days, weeks or months as desired following encapsulation to thereby minimize the likelihood of embolization or other risks of the dissolved material and to avoid the disadvantages of chronic implantation.

623 2365
Abstract:
A device for inducing weight loss in a patient includes a tubular prosthesis positionable at the gastro-esophageal junction region, preferably below the z-line. In a method for inducing weight loss, the prosthesis is placed such that an opening at its proximal end receives masticated food from the esophagus, and such that the masticated food passes through the pouch and into the stomach via an opening in its distal end.

US Classification:
606079000
Abstract:
A system for accessing the interior of a vertebral body or the intervertebral disc space above or below the vertebral body is disclosed. The system comprises a steerable cutting means for creating a path within or through the vertebral body to allow access for other devices to deliver a therapy, and may be housed within a flexible catheter shaft. The steerable cutting means may create a path to allow access to a device for removing tissue, and/or additional a devices for delivering a therapy, such as, for example, a filling material and/or a prosthesis. A method of accessing the interior of a vertebral body or the intervertebral disc space using the system, and a method of treatment of spinal disorders using the system are also disclosed.

International Classification:
A61M029/00
US Classification:
606/200000
Abstract:
A device for trapping plaque against the vascular wall includes a tubular-shaped net which is made from a blood-permeable and biocompatable material having expandable members attached to each end of the tubular net. The expandable members are placed in their expanded position within a blood vessel to maintain the tubular net against the area of plaque to be treated with an interventional procedure. A balloon angioplasty procedure or stenting procedure is subsequently performed within the inner lumen formed in the tubular net. The tubular net prevents any emboli which may be created during the interventional procedure from entering into the bloodstream.

US Classification:
623 2364, 128898
Abstract:
A prosthetic device is described that is positionable within the gastro-esophageal junction region of a patient. The prosthetic device includes a proximal opening and a distal orifice that is adjustable in size prior to and/or following implantation. During use, the prosthetic device is attached to tissue of the gastro-esophageal junction region of the patient, with the device positioned such that food ingested by the patient passes from the esophagus through the proximal opening into the interior of the prosthetic device, and eventually exits the prosthetic device via the distal opening.
