Abstract: A system for providing vascular access in a patient's body may comprise at least one hemostatic valve and at least one clamp to be used with a vascular graft. The vascular graft comprises a tubular body having a proximal end and a distal end, the proximal end being configured to be attached to a vessel in a patient's body. The at least one valve is configured to be attached to the distal end of the graft's tubular body and comprises a housing including a flexible membrane that allows a medical device to be inserted through the membrane into said vascular graft. The valve further comprises an introducer sheath configured to be inserted into the distal end of the graft's tubular body.

Abstract: The present disclosure includes a calculi fracture device having an acoustic transducer for transferring acoustic energy via a primary fragmentation probe to fracture a calculi mass into calculi fragments, an evacuation tube connecting the probe to a pressure source, and a secondary fragmentation device located in an evacuation pathway extending along the fragmentation probe and the evacuation tube to further break up the calculi fragments to inhibit clogging at a more proximal location in the evacuation pathway. A method of inhibiting clogging of a calculi fracture device can include receiving, from a primary fragmentation device, fragments of a calculi mass along a passage of a evacuation pathway of the calculi fracture device and further breaking up the calculi fragments along the passage of the evacuation pathway at a location that is more proximal to a primary fragmentation location.

Abstract: A system for providing vascular access in a patient's body may comprise at least one hemostatic valve (610) and at least one clamp (210) to be used with a vascular graft (110). The vascular graft (110) comprises a tubular body having a proximal end (110A) and a distal end (110B), the proximal end (110A) being configured to be attached to a vessel in a patient's body. The at least one valve (610) is configured to be attached to the distal end (110B) of the graft's tubular body and comprises a housing (616) including a flexible membrane (611) that allows a medical device (810) to be inserted through the membrane (611) into said vascular graft (110). The valve (610) further comprises an introducer sheath (615) configured to be inserted into the distal end (110B) of the graft's tubular body.
