Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61M 5178

US Classification:

60416413, 606194

Abstract:

An improved guidewire for advancing a catheter within a body lumen which has a high strength proximal portion, a distal portion formed of superelastic alloy and a connector formed of superelastic alloy to provide torque transmitting coupling between the distal end of the proximal portion and the proximal end of the distal portion. The superelastic alloy elements are preferably cold worked and then heat treated at a temperature well above the austenite-to-martensite transformation temperature, while being subjected to longitudinal stresses equal to about 5 to about 50% of the room temperature yield stress to impart to the metal a straight âmemory. â The guiding member using such improved material exhibits a stress induced austenite-to-martensite phase transformation at an exceptionally high constant yield strength of at least 70 ksi for solid members and at least 50 ksi for tubular members with a broad recoverable strain of at least about 4% during the phase transformation.

International Classification:

A61M 2500

US Classification:

604265, 604104, 606 32

Abstract:

This is an implantable medical device assembly for use in surgical procedures. It is most preferably an implantable structure having stenting properties but only partially coated with or partially associated with a material causing a localized angiogenic response. One variation of is an artificial occlusion kit having the inventive implantable stenting structure situatable and vaso-occlusive devices. The implantable stenting structure is typically situated so to prevent migration of artificial occlusion devices or implants from an occlusion site, such as an aneurysm, and into an adjacent body space, such as a blood vessel.

International Classification:

A61M 29/00
A61M 25/00

US Classification:

604 9601, 604523, 604533

Abstract:

An intravascular catheter such as a dilatation catheter for angioplasty procedures having a removable distal shaft section. The catheter construction allows the original distal shaft section of the catheter to be removed and a replacement distal shaft section to be secured to the proximal section which is useful with angioplasty catheters when the dimensions of the balloon on the original distal shaft section are inappropriate for dilating a particular stenotic region. Such catheter construction is also useful when there is a need to implant a stent into a dilated stenotic region to maintain its patency.

International Classification:

A61N 1/00

US Classification:

607116, 607115, 607129

Abstract:

An expandable intravascular medical device comprises an arcuate spring configured to be expanded into contact with the inner surface of a blood vessel. Another medical device comprises an electrode support structure, e. g. , a non-tubular arcuate structure or a cylindrical member, and a plurality of resilient spring loops laterally extending from the support structure. The contact created between the loops and a blood vessel is sufficient to anchor the medical device within the blood vessel. In another embodiment, the medical device comprises an elongated member and two resilient spring arms extending distally from the elongated member. The arms are configured to be laterally moved towards each other to place the medical device in a collapsed geometry, and configured to be laterally moved away from each into contact with an inner surface of a blood vessel to place the medical device an expanded geometry.

International Classification:

A61N 1/00

US Classification:

607 45

Abstract:

A method of treating a neurological disorder in a patient is provided. The method comprises intravascularly delivering a stimulation lead within the head of the patient, and placing the stimulation lead adjacent brain tissue (e. g. , cortical brain tissue or deep brain tissue), the stimulation of which will treat the neurological disorder. The stimulation lead can be placed into indirect contact with the brain tissue (e. g. , through a blood vessel) or indirect contact with the brain tissue (e. g. , when placed within the ventricular cavity or by being introduced through an exit point within a vessel wall). Optionally, the method comprises implanting a source of stimulation within the patient's body, and then electrically coupling the proximal end of the stimulation lead, which conveniently extends from the access point within the circulatory system, to the implanted stimulation source. Using the stimulation lead, the brain tissue can then be stimulated in order to treat the neurological disorder.

Abstract:

A method of treating a disorder in a patient is provided. The method comprises delivering a stimulation lead within a blood vessel, intralumenally puncturing a wall of the blood vessel to create an exit point, and then introducing the stimulation lead through the exit point into direct contact with tissue the stimulation of which treats the disorder. Optionally, the method comprises implanting a source of stimulation within the patient's body, and then electrically coupling the proximal end of the stimulation lead to the implanted stimulation source. Using the stimulation lead, the tissue can then be stimulated in order to treat the disorder.
