A delivery catheter (12) for a stent valve (10), the delivery catheter having a distal portion (14) insertable into an anatomy, the distal portion comprising an accommodation region (18) for accommodating a stent-valve for delivery into the anatomy, the delivery catheter further comprising at least one sheath (20; 22) that is translatable between a closed position for at least partly closing the accommodation region and an open position for at least partly opening the accommodation region.

A flow regulator for a blood collection assembly includes a housing having an inlet and an outlet, which defines an interior space between the inlet and the outlet. A membrane having a first surface and a second surface is disposed at least partially within the interior space. The membrane has a first position where a flow path between the inlet and the outlet is substantially open, and a second position where the flow path between the inlet and the outlet is at least partially restricted. The membrane is configured to move between the first and second positions in response to a pressure differential acting on the membrane.

A lithotripsy device can comprise a handpiece, a lithotripsy probe extending from the handpiece, an energization source configured to deliver an energy to a distal end of the lithotripsy probe, a suction passage extending from the distal end of the probe and through the handpiece, and a capture device comprising a container comprising a storage space, an entry port configured to couple to the handpiece at the suction passage, and an exit port, and a capture element connected to the container and configured to facilitate capture of stone fragments within the storage space. A method can comprise fragmenting stones with a lithotripsy device, drawing a vacuum through the lithotripsy device to pull stone fragments and waste fluid therethrough, pulling the vacuum through a stone capture device connected to the lithotripsy device, depositing stone fragments within the stone capture device using a capture element, and drawing the vacuum through the device.

Needle assemblies and related methods in which a valve opener is pushed into a valve to open one or more slits parting a plurality of flaps on the valve to open the valve, creating an internal reaction force within the plurality of flaps. The plurality of flaps of the valve utilize the internal reaction force to retract back to a closed position following removal of the valve opener from the valve, thereby sealing the valve until reopened if reused. The needle assemblies each include a needle hub with a needle, a catheter tube with a catheter hub, the valve, and the valve opener positioned in an interior cavity of the catheter hub.

A lithotripsy device can comprise a handpiece, a lithotripsy probe extending from the handpiece, an energization source configured to deliver an energy to a distal end of the lithotripsy probe, a suction passage extending from the distal end of the probe and through the handpiece, and a capture device comprising a container comprising a storage space, an entry port configured to couple to the handpiece at the suction passage, and an exit port, and a capture element connected to the container and configured to facilitate capture of stone fragments within the storage space. A method can comprise fragmenting stones with a lithotripsy device, drawing a vacuum through the lithotripsy device to pull stone fragments and waste fluid therethrough, pulling the vacuum through a stone capture device connected to the lithotripsy device, depositing stone fragments within the stone capture device using a capture element, and drawing the vacuum through the device.

A catheter assembly is provided with a catheter, a catheter hub, and a valve body (medical valve) provided in the catheter hub. The valve body includes a hollow main body provided with a distal end surface and a fixing portion for fixing the valve body to the catheter hub. At least a part of an outer peripheral surface and at least a part of an inner peripheral surface of the main body are inclined with respect to a central axis of the valve body. The main body of the valve body includes a distal end slit provided on the distal end surface and a side slit provided on the outer peripheral surface of the main body and continuously extending from the distal end slit.
