The invention comprises an atherectomy probe for mechanically cutting core prostatic tissue to alleviate the condition of benign prostatic hyperplasia (BPH) or for use in orthopedic procedures. The blade shapes and lengths are adaptable but in a preferred embodiment the device includes an end-cutting bur tip. The cutting motion may be one of: guillotine (incising between two parallel edges), radial reciprocating (changing radial directions and cuts between two horizontal edges), circular (continuously radial in one direction), and end-cutting, etc. The power source used to drive the blade may be one of: pneumatic, hydraulic, manual mechanical, electrical, solar, etc. The probe also includes several channels that may be used for providing live aspiration and removal of severed tissue and fluids, as well as insufflation of gases and optionally, pharmaceuticals and/or a secondary therapy. The instrument is designed for use in open, endoscopic, and minimally invasive transurethral or transperineal surgical procedures.
A probe for mechanically cutting comprising:
A device for use in performing a surgical procedure through a natural bodily lumen comprising a balloon sheath for luminal protection, through which one or more surgical instruments can be passed, the sheath comprising columnar supports along a longitudinal length thereof and a clear, lubricated tip at a distal end to facilitate anatomic visualization during insertion, wherein the tip can be peeled away following delivery, and wherein the sheath is capable of being tubular-rolled in its deflated condition and unrolls upon inflation with a coolant fluid.
A method of treating benign prostatic hyperplasia comprising:
