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 neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

The expandable sheath and system (10) for intravascular insertion of a medical implement includes a cannula (70) for entering a lumen of a vascular vessel of a patient, a guide wire (72) insertable into the lumen, an introducer and dilator (62) adapted to follow the guide wire (72) into the lumen, an expandable sheath (40) positioned on the introducer and dilator (62), with the expandable sheath (40) being adapted to be positioned in the vessel, and an extension collar (76). The medical implement is received within the vessel by passing through the sheath (40) upon separating the introducer and dilator (62) therefrom. In one embodiment, a linear array of perforations (50) formed through the expandable sheath (40) allow for expansion. Alternatively, an external slit (16) may be provided for selective expansion of the sheath (40).

Methods and devices for performing transjugular carotid flow reversal are provided. A flow reversal sheath is advanced through a transjugular carotid fistula. An occlusion balloon is inflated, causing carotid inflow to be diverted through the sheath and through a flow reversal region positioned in the jugular vein. After reversal of blood flow, a carotid intervention is performed.
