Abstract
Apparatus and methods for a stone fragment suction device are provided with fluid flow paths at a distal tip to encourage creation of turbulence or a vortex to enhance stone dust or debris removal via directed flow using targeted fluid exit conduits. An apparatus includes a steerable access sheath having a proximal end and a distal end, a tip at the distal end, directed flow channels at the distal tip, and a suction conduit positioned within a central lumen of the steerable access sheath from the distal end to the proximal end, the steerable access sheath containing an outer lumen surrounding the central lumen with one or more channels therethrough, the steerable access sheath may further include a radiopaque material at the distal end or along a length of the steerable access sheath to enable tracking with a remote fluoroscopic device.
