US Patent:

6695863, Feb 24, 2004

Filed:

Jan 8, 1997

Appl. No.:

08/767119

Inventors:

Kamal Ramzipoor - Union City CA
Gary Schneiderman - Walnut Creek CA

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61M 2900

US Classification:

606194, 60410305, 60410309, 604 9601

Abstract:

A dilatation catheter assembly which has a dilatation catheter with a sheath mounted on the catheter shaft having an inner lumen extending in the distal portion of the sheath which is configured to slidably receive at least a portion of the dilatation balloon on the distal end of the catheter. The position of the sheath is fixed with respect to the catheter, e. g. a friction fit or bonded in some manner, before the assembly is inserted into the patients vasculature with the distal portion of the sheath covering a portion of the balloon but leaving a portion of the balloon uncovered with a length equal to the stenotic region to be dilated so that the entire stenosis can be dilated at the same time. The distal portion of the sheath is preferably formed of a flexible polymeric tube with inelastic reinforcement to prevent substantial expansion thereof when the balloon is inflated.

Assignee:

Kyphon Sarl - Neuchatel

International Classification:

A61M 29/02

US Classification:

606192

Abstract:

An expandable surgical access device can include an elongate member comprising an expansion lumen between a proximal end and a distal end, and an expandable body operably attached to the distal end of the elongate member. The expandable body can be inserted to an internal location in a body in a collapsed configuration. When in a desired position, the expandable body can be expanded outward to an expanded configuration. In the expanded configuration, the expandable body can be adapted to protect adjacent anatomical structures and can have an internal diameter defining an operating lumen sufficient to allow passage of a cannula through the operating lumen. The expandable body may be further expanded inward to a constricting configuration whereby the expandable body can be adapted to constrict about and anchor the cannula in the operating lumen.

International Classification:

A61F 2/01

US Classification:

606200

Abstract:

A self-expanding basket for use in conjunction with an embolic filtering device has a proximal set of struts which are connected to a distal set of struts by a bending region which provides enhanced bending characteristics to the basket. The bending region can be formed by intermediate links which are extremely flexible and bendable to allow the basket to be delivered through tortuous anatomy. The intermediate links are extremely flexible and create a mechanical hinge-like connection between the proximal and distal strut assemblies. The basket thus is capable of substantial bending when being delivered through the patient's vasculature and will bend and conform to the patient's anatomy once positioned for filtering purposes. The intermediate links can also lengthen, when needed, when positioned in a curved vessel in the patient's vasculature, when needed. As a result, the basket will easily conform to a curved body vessel to maintain proper wall apposition of the filtering element with the wall of the body vessel.

Appl. No.:

10/025149

Inventors:

William Webler - Escondido CA, US
Gary Schneiderman - San Ramon CA, US
Douglas Seiffert - Pembroke FL, US

Assignee:

Advanced Cardiovascular Systems, Inc.

International Classification:

A61B001/00

US Classification:

600/121000

Abstract:

The invention is directed to apparatus, methods and systems including a sheath for use with intracorporeal optical imaging instruments such as imaging guidewires, catheters, or endoscopes. The invention provides a sheath suitable for guiding an enclosed instrument, that is effective to guide the placement within a patient's body and replacement to a distal position after retraction of the imaging instrument, as during an imaging scan. The sheaths may include at least a portion that is translucent to a desired wavelength of radiation. The translucent portion may have an index of refraction similar to the index of refraction of a bodily fluid such as blood plasma, or an artificial fluid suitable for introduction into a body lumen.

US Classification:

606 79, 606 96, 606104, 604 9601, 606102

Abstract:

A system for performing a medical procedure includes an introducer and a guide pin that include features that coordinate to indicate the distance the guide pin is extended beyond the tip of the introducer when both are deployed at a target location. By incorporating measurement features into the guide pin/introducer combination, accurate measurement capabilities are provided without requiring dedicated measurement tools.

International Classification:

B25B 2714

US Classification:

29270

Abstract:

A tool for applying a membrane on a small upstanding post like device, which tool incorporates a housing with means for securing the membrane across the top of the post with additional means disposed opposite the post for holding the membrane against the post and urging it down the side of the post, the housing being closeable to serve as a shipping container and a calibration cell for the device to be membraned with means to secure the post captive with little or no chance of its falling into a non-sterile environment.

Appl. No.:

8/705945

Inventors:

Gary Schneiderman - San Ramon CA

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61N 500

US Classification:

600 1

Abstract:

The invention is directed to a rapid exchange type intravascular catheter suitable for maintaining patency of a body lumen for a period of time sufficient to permit delivery of a radiation source to the body lumen. The catheter utilizes a reinforcing mandrel to improve the pushability and strength of the catheter as it tracks along a guide wire, and permits blood flow through an inflatable member while radiation therapy is being provided.

International Classification:

A61B 504

US Classification:

128644

Abstract:

For use with the human eye, especially, there is provided a relatively narrow, split, flexible partial ring adapted to fit against the portion of the eyeball behind the upper and lower eyelids. The corneal opening is of an extent so that despite normal excursions of the cornea, the cornea does not substantially contact the ring. The split ring is formed of highly flexible material so as to permit a substantially universal fit and at the same time exert minimal effect on the physiological parameters being measured. A sensor or other device is located on a widened portion of the carrier in contact with the palpebral conjunctiva. A conductor or other transmission device may lead from the device through a projection, preferably integral with the ring, and extending beyond the eyelids. The device carrier is a split ring and relies upon its shape and self-resiliency in order to maintain its position within the eye.
