Appl. No.:

09/724914

Inventors:

Thomas J. Clement - Redmond WA
Edward I. Wulfman - Woodinville WA
Craig E. Lawson - Redmond WA

Assignee:

Pathway Medical Technologies, Inc. - Redmond WA

International Classification:

A61B 1714

US Classification:

606180, 606159, 606171, 604 22

Abstract:

Intralumenal material removal systems are provided using an advanceable, rotatable and expandable cutter assembly. The intralumenal material removal system includes a cutter assembly positionable in the lumen of a mammalian subject and operably connected to system controls. The cutter assembly comprises a distal cutting head and an adjustable cutting assembly that is axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. The adjustable cutting assembly is adjustable between a smaller diameter condition and a larger diameter condition. The cutter may thus be introduced to and withdrawn from the material removal site in a retracted, smaller diameter condition that facilitates translation and navigation of the device through various lumens. The adjustable cutting assembly may be selectively expanded at the material removal site to facilitate cutting, removal and aspiration of the occlusive material.

Abstract:

The intralumenal material removal system includes a cutter assembly positionable in the lumen of a mammalian subject and operably connected to system controls. The cutter assembly is axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. One cutter assembly comprises an adjustable cutter that is adjustable between a smaller diameter condition and a larger diameter condition by rotation of the drive shaft in opposite directions. The cutter may thus be introduced to and withdrawn from the material removal site in a retracted, smaller diameter condition that facilitates translation and navigation of the device through various lumens. The adjustable cutting assembly may be selectively expanded at the material removal site to facilitate cutting, removal and aspiration of the occlusive material. One composite cutter assembly comprises both a distal, fixed diameter cutter and a proximal adjustable diameter cutter.

Abstract:

A memory exhaustion condition is handled in a data processing system having first and second regions of physical memory. The memory exhaustion condition is detected while the second region is mirroring at least part of the first region. In response to the memory exhaustion condition, memory mirroring is at least partially deactivated and at least part of the second region is utilized to augment the first region, such that the memory exhaustion condition is eliminated. In an illustrative embodiment, the data processing system compresses real memory into the first region of physical memory, and the memory exhaustion condition arises when the first region lacks sufficient available capacity to accommodate current requirements for real memory. The memory exhaustion condition is eliminated by compressing at least part of the real memory into the second region.

Inventors:

Edward Wulfman - Woodinville WA, US
Thomas Clement - Redmond WA, US

International Classification:

A61F002/06

US Classification:

623/001150, 606/157000

Abstract:

The present invention provides a radially expandable device for use in the occlusion and repair of an undesired dilation in a vessel, such as an aneurysm, while maintaining flow both through the vessel and through branches of the vessel that may be located in proximity to the aneurysm. This is achieved by having a device with a differential pore size, wherein the portion of the device positioned in proximity to the aneurysm is of substantially smaller pore size than that portion of the device positioned away from the aneurysm.

International Classification:

A61F 2/04

US Classification:

604 8

Abstract:

A medical treatment device includes an elongate member having an internal volume, a proximal end, and a distal end, the internal volume extending from the proximal end to the distal end. The medical treatment device further includes a first coupler and a second coupler, the first coupler and the second coupler coupled to the internal volume of the elongate member; a first joining member and a second joining member, the first joining member coupled to the first coupler and the second joining member coupled to the second coupler. The first joining member is configured to attach to a first biological matter location, and the second joining member is configured to attach to a second biological matter location, the second location being distal to the first location. The second coupler is configured for manipulation to align relative the first coupler such that the second biological matter location relocates adjacent the first biological matter location. The first joining member and the second joining member are configured to join the first biological matter location to the second biological matter location.

Appl. No.:

8/360207

Inventors:

Edward I. Wulfman - Woodinville WA
Thomas J. Clement - Redmond WA

Assignee:

Boston Scientific Corporation - Redmond WA

International Classification:

A61B 1732

US Classification:

606159

Abstract:

The invention is a device for medical applications for differentially cutting abnormal deposits from within a patient's vessels. The device comprises one or more diamond plated burrs or cuffs attached to a flexible drive shaft which rotates at a high speed. The drive shaft is placed over a preformed shaped guidewire so that the drive shaft conforms to the shape of the guidewire, which has been preformed into a gentle "S" or "cork-screw" shape. The guidewire may be rotated at low speed.

International Classification:

A61B 1732

US Classification:

128305

Abstract:

An electromechanical system which may be used in conjunction with spinning catheters, such as those which have differential cutting burrs, includes an electric prime mover which attaches to an advancer assembly. The advancer assembly has an off-axis drive and apparatus for loading a catheter unit, which is driven through a catheter engagement coupling. The catheter assembly can also include one or two lumens with access ports at the advancer assembly, whereby medicines may be injected or pressure readings may be obtained from the vessel.
