  • Patent number: 9480468
    Abstract: A vascular closure system (10) includes a dual lumen tube (14), an inflatable balloon (16), and a distal sealing assembly (18). The dual lumen tube includes a proximal end portion, a distal end portion, a first lumen, and a second lumen. The first lumen is coupled in fluid communication with an inflation fluid and has a first distal opening at a distal end of the dual lumen tube. The second lumen extends from the proximal end portion to the distal end portion. The inflatable balloon is mounted to the dual lumen tube in fluid communication with the first lumen, and is inflatable within a vessel to temporarily seal closed a tissue puncture. The distal sealing assembly includes a distal sealing member (74) positioned distal of the inflatable balloon, and is detachable from the distal sealing assembly at a location exterior and adjacent to the vessel.

  • Publication number: 20150119978
    Abstract: In some embodiments, an apparatus includes a catheter assembly and a handle assembly that can be removably coupled to the catheter assembly. A valve holding tube defines a lumen configured to receive a prosthetic mitral valve in a compressed configuration and can be removably coupled to a distal end portion of the handle assembly. The valve holding tube can be received within a hub of the catheter assembly when coupled to the handle assembly. The actuator when actuated is configured to cause the tensioning unit to travel along a traveler strap of the catheter assembly moving the handle assembly distally such that a distal end of an elongate shaft of the handle assembly moves the prosthetic mitral valve distally out of the valve holding tube and out a distal end of the sheath such that the prosthetic mitral valve is free to move to a biased expanded configuration.
