Title: Infusion balloon catheter
Inventor: SPARKS KURT D
IPC: A61F2/958
Filed: 1997-02-26
Abstract: Apparatus and method is disclosed relating to an infusion catheter for treating a subject region with a treatment solution. A guide catheter (10) allows the infusion catheter (12) to be inserted into the subject and placed near a treatment region within the vascular system.  A solution source is used to selectively inflate an infusion device. A  passageway (14) in the catheter body extends to an infusion device which has inner and outer chambers (140, 150). Holes in a wall of the inner chamber (140) route solution into the outer chamber (150) and holes (154) in the wall of the outer chamber (150) route the solution into a subject vasculature. Solution pressure in the inner chamber (140) is greater than the solution pressure in the outer chamber (150) due to the relatively greater area of the holes (154) in the outer chamber wall (152).

IPC: F15B15/08
Filed: 1998-10-23
Abstract: Internal bearings for a rodless piston assembly. The  internal  bearings  are  seated  on  inclined  rail structures of a transmission bracket.  Force applied to the  internal  bearings  causes  them to  slide  up  the inclined rail structures and press against the inner surface of the rodless piston bore.  As a result,  a radially inward force is applied to the transmission bracket. This radially inward force is transmitted to a saddle and external bearing assembly.   The internal bearings thus hold the saddle against the outer surface of the rodless piston cylinder.   Piston elements for rodless piston assemblies are movably coupled to the transmission brackets so that the piston elements float with respect to the transmission bracket.  The floating piston elements can self-align with the rodless piston bore

Abstract: A computationally efficient multiplication method and apparatus for modular exponentiation. The apparatus uses a preload register, coupled to a multiplier at a second input port via a KN bit bus to load the value of the "a" multiplicand in the multiplier in a single clock pulse. The "b" multiplicand (which is also KN  bits long) is supplied to the multiplier N bits at a time from a memory output port via an N bit bus coupled to a multiplier first input port. The multiplier multiplies the N  bits of the "b" multiplicand by the KN bits of the "a" multiplicand and provides that product at a multiplier output N bits at a time, where it can be supplied to the memory via a memory input port.

Abstract: A diaphragm valve for the water intake in irrigation systems or similar comprises a hollow body (1) having a port (1a) to connect a hydraulic or pneumatic system to the interior of the body of the valve and at least one ventilation opening through a side wall or walls of the body from the exterior to the interior of the valve. A diaphragm (7) is movably mounted within the interior of the body and normally closes the port. There is a bleed aperture through the diaphragm around the guide member (10) to a cavity (12) behind the diaphragm. When the pressure on the port side of the diaphragm falls below the external pressure, the diaphragm will move away from the port to open the port to fluid entering the interior of the body of the valve through the side wall(s) of the body of the valve, and the diaphragm will move to close the port when the pressure on the port side of the diaphragm is equalised whith the external pressure. Preferably the diaphragm comprises a thin flexible annular skirt (7c) extending from the periphery of the diaphragm with the distal edge of the skirt retained in an annular recess (8) around the cavity behind the diaphragm to movably mount the diaphragm within the interior of the body of the valve so that the diaphragm moves by flexing and/or folding of the skirt.
