| 20090036834 | ELONGATE MEDICAL DEVICE HAVING ENHANCED TORQUE AND METHODS THEREOF - An elongate medical device such as a guidewire, that may comprise a first elongate member having a proximal end, a distal end and a lumen there between, a second elongate member having a proximal end and a distal end, the second elongate member at least partially disposed in the first elongate member, a first connection between first elongate member and the second elongate member at the proximal end of the first elongate member, a second connection between the first elongate member and the second elongate member at the distal end of the first elongate member, and a third connection between the first elongate member and the second elongate member, the third connection disposed at a point between the first connection and the second connection, wherein the third connection is substantially at a location selected by the Method for Enhancing the Ratio of Torsional Stiffness to Transverse Flexibility. | 02-05-2009 |
| 20090124974 | Mechanical Volume Control for Injection Devices - A needleless fluid delivery system allowing for selective control of amounts of therapeutic fluids that are administered to treatment sites within a patient. The fluid delivery system includes an injector source and an access device. The fluid delivery system generally includes an adjustable volume control system for selectively metering the amount of therapeutic fluid to be delivered to the treatment location. The adjustable volume control system generally includes a mechanical stop system with a plunger member and a stop member, wherein the plunger member and stop member physically interact to restrict a plunger insertion length which simultaneously controls an amount of therapeutic fluid expelled by said plunger. | 05-14-2009 |
| 20090259213 | INJECTION TUBE FOR JET INJECTION DEVICE - A non-metal, polymeric tubular device for delivering a therapeutic fluid to a treatment site within a patient. The non-metal, polymeric tubular device can be fabricated using suitable high strength polymers and in some versions can be reinforced through the inclusion of reinforcement materials or braiding. The non-metal, polymeric tubular device can be fabricated so as to have a burst strength exceeding at least about 2,000 psi. The non-metal, polymeric tubular device can be fabricated so as to have distention properties, wherein an orifice or jet port located at a distal end of the polymeric tubular device retains its shape and/or size without suffering swelling that can have a detrimental impact on a fluid jet used to deliver the therapeutic fluid at the treatment site. | 10-15-2009 |
| 20110160754 | SPRING-LOADED ANASTOMOSIS DEVICE AND METHOD - An anastomosis device and related methods for performing an anastomosis procedure, such as rejoining a urethra with a bladder following a radical prostatectomy. The engagement structures each have deployable tines for grasping the tissue proximate to the end of the biological lumen and the opening in the bodily organ. The anastomosis device also has a positioning apparatus for dynamically maintaining the engagement structures in proximity throughout a healing process such that tissue to be joined remains in approximation. | 06-30-2011 |
| 20110270216 | METHOD AND APPARATUS FOR COMPENSATING FOR INJECTION MEDIA VISCOSITY IN A PRESSURIZED DRUG INJECTION SYSTEM - A needleless injection system is provided to deliver therapeutic fluids to an internal treatment site in a patient, where the system is pressurized and is capable of compensating for differences in injection media viscosity and mechanical system characteristics. In one aspect, a needleless therapeutic fluid injection system is provided that includes modular, interchangeable components. In particular, the system includes a console that generally includes the electronic and/or hydraulic control components for the system, an injection chamber, and a shaft or catheter tube. | 11-03-2011 |
