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.

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.

Drug delivery catheter

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.

A method for providing a conductive metal deposit on the surface of a dielectric substrate by applying a composition comprising a mixture of a salt and amine or amide compound to the substrate and subjecting the composition to a continuous wavelength laser beam.

Laser direct writing

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.
