Publication number: 20060264849Abstract: A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip.Type: ApplicationFiled: May 3, 2006Publication date: November 23, 2006Inventors: George Lopez, Thomas Fangrow, David Arnold, Bruce Hubrecht, Alison Brummett, Thomas Gustus, Dennis Bui

Publication number: 20050055017Abstract: The malleable cryosurgical probe includes a cryostat assembly and a cryoprobe assembly. The cryostat assembly includes an elongated shaft assembly having a bellows portion thereof and a closed distal end. The shaft assembly includes at least one freezing portion comprising the bellows portion, at least one thermally insulated portion and a thermally insulating element positioned about the thermally insulated portion. A cryostat is operably associated with the elongated shaft assembly. It includes a cryostat inlet for receiving gas entering the cryostat, a cryostat outlet and a heat exchanger positioned between the cryostat outlet and the cryostat inlet. The heat exchanger receives gas from the cryostat inlet and provides heat transfer between gas flowing within the cryostat and fluid exterior thereto. At least one Joule-Thomson nozzle is in fluid communication with the cryostat outlet. The at least one Joule-Thomson nozzle expands gas expelled therefrom.Type: ApplicationFiled: July 21, 2004Publication date: March 10, 2005Inventors: Sanford Damasco, Dennis Bui, Xiaoyu Yu

Patent number: 6413269Abstract: A stent delivery catheter. The catheter includes an inner catheter tube and an outer catheter tube which are rotatable relative to each other. The inner catheter and outer catheter include recesses to receive the ends of the stent, permitting pull wires to engage the stent ends without need to for the pull wires to extend radially beyond the bounds of the catheter or requiring the stent ends to protrude it into the lumen of the inner or outer catheter.Type: GrantFiled: July 6, 2000Date of Patent: July 2, 2002Assignee: Endocare, Inc.Inventors: Dennis Bui, Jay J. Eum, Paul W. Mikus
