US Patent:

20070244413, Oct 18, 2007

Filed:

Apr 12, 2006

Appl. No.:

11/403043

Inventors:

James Biggins - Waltham MA, US

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61M 25/00

US Classification:

600585000

Abstract:

A medical guidewire having a core-to-tip construction that includes a core wire region surrounded by a flexible coil. The core wire having a distal tip segment that includes a proximal flat drop axially separated from a distal flat drop by a cylindrical or frusto-conical linking portion. The proximal and distal flat drops each having a pair of parallel planar surfaces, wherein the planar surfaces of the proximal flat drop are at an angle to the planar surfaces of the distal flat drop. The tip construction provides improved flexibility while maintaining columnar strength and providing excellent torsional characteristics.

Abstract:

A wear monitor for footgear can indicate when a shoe or component may have exceeded its expected useful life. The indication can be triggered by a measure of use, such as steps taken or distance accrued in the shoes, either through estimation or actual measurements. The monitor can take into account varies parameters related to the individual wearer of the shoe and environmental factors to more accurately determine when a pair of shoes has reached a wear out period. By employing sensors, the monitor can also be measure certain operating parameters of the shoe, such as the loss of a critical amount of resilience, and indicating to the wearer that the shoes are no longer adequate to protect the wearer from injury. The wear monitor can be fabricated into the shoe during manufacturing or can be a portable stand-alone device and can employ various technologies to provide a status indication to the wearer.

International Classification:

A61F 2/82

US Classification:

623 115

Abstract:

An endoprosthesis includes a stent structure having an elongate member longitudinal portions of which overlap to define the crossover structures. The stent structure may also include loop structures, which are contiguous with the crossover structures, through which a filament extends. A guard structure is secured to the stent structure and located adjacent to the crossover structures to obstruct displacement of the filament between the longitudinal portions of the elongate member of the crossover structures. A method for operating the endoprosthesis includes displacing the loop structures toward one another along the filament to displaced positions relative to the suture structure for reducing the respective profiles of the stent structure and patch structure.

Abstract:

A guiding catheter for placement in a patient's vessel. The catheter includes an elongate hollow shaft with open proximal and distal ends and a bore extending there through. The catheter shaft includes an inner liner, a metallic reinforcement layer overlying the inner liner, and a unitary outer jacket covering the reinforcement layer. A distal portion of the outer jacket of the catheter shaft is chemically softened to be more flexible than a proximal portion of the outer jacket. A connector fitting is mounted at the proximal end of the shaft in communication with the bore and a distal tip is attached to the distal end of the shaft. A method of manufacturing the guiding catheter is also disclosed.
