US Patent:

51354985, Aug 4, 1992

Filed:

Apr 2, 1990

Appl. No.:

7/503720

Inventors:

Robert J. Kam - San Jose CA
Rolf A. Faste - Stanford CA
Anthony J. Castro - San Francisco CA

International Classification:

A61M 3700

US Classification:

604140

Abstract:

A means for elimination or compression of trapped air spaces in osmotically powered pumps is disclosed in which the housing of the pump is constructed of movable portions so that movement of the said housing portions will force air out of the device or compress it to such an extent that activation of the pump will result in the minimum lag time between activation of the pump and infusate flow.

International Classification:

A61M 2900
A61B 1700

US Classification:

606159

Abstract:

An athetectomy catheter is disclosed having a composite cutter which is capable of cutting material, including hardened plaque, from a biological conduit. The composite cutter has a cutter and a sensor mount. The cutter has a proximal end and a distal end with a cutting edge. The proximal end of the cutter bonds with the sensor mount. The sensor mount is adaptable for holding a sensor and attaching to a cutter torque cable of an atherectomy catheter. Typically, the atherectomy catheter has a cutter housing with a window. The composite cutter is positioned in the cutter housing and moves in response to movement of the cutter torque cable to cut material from the biological conduit via the window.

Devices For Vascular Intervention - Redwood City CA

International Classification:

A61M 3100

US Classification:

604 53

Abstract:

A device and method for the localized treatment of vasculature with drugs and medicaments is described herein. Centrifugal force is used to drive a material from a reservoir to the outer surface of the application device and thereby deliver the treatment substance to the chosen area.

Assignee:

Devices for Vascular Intervention - Santa Clara CA

International Classification:

A61B 1732

US Classification:

606170

Abstract:

An intravascular directional atherectomy device is disclosed. The apparatus comprises a catheter body having a distal end, a proximal end and an axial lumen therebetween. A housing having an open interior and an aperture on a lateral side thereof is attached to the distal end of the catheter body. An atheroma severing device is disposed within the housing. The device includes a cutter that is slidably disposed on a saddle which is connected to the housing. A track member is disposed in the axial lumen of the catheter body and has a distal end connected to the housing. Slidable movement of the atheroma severing device severs the stenotic material that has been urged within the aperture. The saddle enables the inflexible portion of the housing to be minimized in order to fit in the very tortious regions of biological conduits.
