Abstract: A cervical tissue sampling device (10) to allow women to collect tissue samples at home for transmission to a laboratory by mail or other means includes a cylindrical barrel (12) having an open circular front end (14) and an open circular rear end terminating in a radially extending irregularly shaped finger grip flange (16). A plunger assembly (33) slidably received within the barrel (12) includes a circular brush (34) and surrounding circular sponge (40) for collecting cervical tissue and mucus. The brush (34) and sponge (40) collection assembly is detachably secured to the plunger (33) shaft by a quick release connection (52, 54, 56, 58, 60, 62). In use, the barrel (12) is inserted by a female into her vagina (v) with the sponge (40) and brush (34) disposed in a retracted condition within the barrel (12). After insertion, the plunger (33) is moved to an extended condition and rotated to collect tissue and mucus samples on the brush (34) and sponge (40). After the samples have been collected, the sponge (40) and brush (34) are detached from the plunger shaft (33) and mailed in a sealed container to a laboratory for analysis.

Title: Balloon catheter shaft design
Inventor: JORDAN AMANDA
IPC: A61F2/958
Filed: 2005-06-28
Abstract: A balloon catheter for medical treatment of a patient, including therapeutic dilatation or deployment of medical devices such as stems or grafts. The balloon catheter has an "over-the-wire configuration, including a proximal hub defining an inflation port and a guidewire port, a flexible shaft defining an inflation lumen and a guidewire lumen, a balloon near a distal end of the catheter, and a distal guidewire port. At least a portion of the shaft has an inner tubular body defining at least a portion of the guidewire lumen, surrounded by an outer tubular body defining at least a portion of the inflation lumen. A proximal portion of the inner body is reinforced by a hypotube, which provides much greater column strength and torsional stiffness.  A distal end of the hypotube provides a graduated flexibility transition with a distal spiral-cut segment, in which the pitch of the spiral cut pattern decreases to provide increasing flexibility.

Abstract: The present invention offers a novel control system for a multiphase motor.  The control system involves energization circuitry for energizing each phase winding, and a control circuit for defining phase currents for individual phases of the motor to generate control signals applied to the energization circuitry for energization of the phase windings. When at least one phase of the motor fails, a mode selection circuit enables the control circuit to operate either in a non~correction mode or in a fault-correction mode. In the non-correction mode of operation, phase currents for phases that remain operational are maintained unmodified. In the fault-correction mode, the phase currents for the remaining phases are modified in accordance with pre-set parameters.
