Patent number: 8888812Abstract: An apparatus for sealing a passage through tissue includes a plug including external threads, a lumen extending between its proximal and distal ends, and an annular collet slidably disposed within the lumen. The plug is carried on a distal end of a handle device that includes an inner member with a distal end that is slidable axially within the lumen of the body for moving the collet into a reduced cross-sectional region of the lumen, thereby compressing the collet to seal the lumen, and for deploying the plug from the handle device. During use, the plug is delivered into a passage through tissue over a guide wire. Once a desired location is reached, the plug is deployed from the handle device, thereby compressing the collet and sealing the lumen. The guide wire and handle device are removed, leaving the plug to seal the passage.Type: GrantFiled: November 14, 2011Date of Patent: November 18, 2014Inventors: Richard S. Ginn, Daniel T. Wallace, Robert C. LaDuca

Patent number: 8409248Abstract: An apparatus for sealing a passage through tissue includes a bioabsorbable, threaded plug carried by a delivery device. A guide wire is receivable through lumens in the plug and delivery device that includes wings on a bioabsorbable distal portion. With the wings collapsed, the guide wire is advanced through the passage into a blood vessel, the wings expanding once located within the vessel, and the guide wire is withdrawn until the wings contact the vessel wall. The plug is threaded into the passage over the guide wire until the plug is disposed adjacent the wings. The distal portion of the guide wire is secured to the plug, e.g., by compressing a collet within the plug lumen that seals the lumen, and is severed from a proximal portion thereof. Thus, the plug and distal portion are deployed with the plug sealing the passage.Type: GrantFiled: July 9, 2010Date of Patent: April 2, 2013Inventors: Richard S Ginn, Daniel T Wallace, Robert C LaDuca

Patent number: 8066664Abstract: A catheter capable of articulating in two and three directions is provided. Articulation at the distal tip of the catheter is facilitated by applying selective tension on a steering wire disposed in a lumen that resides peripheral to a central working lumen. Tension on the steering wire through the peripheral lumen causes the catheter tip to bend while the central working lumen resists compression.Type: GrantFiled: December 12, 2006Date of Patent: November 29, 2011Assignee: Taheri LaDuca LLCInventors: Robert C.
