1. A system for treating tissue comprising:
- a probe configured for insertion through a skin into a tissue for mechanically cutting, the probe comprising a cutting core disposed in a housing, the cutting core having at least one sharp edge located at a distal port of the cutting core for cutting, the cutting core also having a channel formed therein for providing aspiration of fluid and bulk tissue from the distal port while the sharp edge is cutting;
a surgical console for controlling aspiration through a flexible tubing line connected thereto which is in fluid communication with the cutting core channel;
a pinch valve in fluid communication with the flexible tubing line for releasing aspiration in the flexible tubing line and cutting core channel so that aspired tissue may be selectively released from the distal port;
a sealing device on the probe for simultaneously tamponading, inducing hemostasis, and dilating a plurality of lumens, said device including a plurality of tamponading balloons configured for inflation with a coolant fluid; and
an inflatable sheath having a lumen therein sized to receive the probe.

Abstract
The invention comprises a system to alleviate conditions such as prostate cancer, benign prostatic hyperplasia (BPH), and the like. The system includes a probe for mechanically cutting tissue and a device for simultaneously tamponading, inducing hemostasis, and dilating a plurality of lumens while minimizing inflammation. The tamponading device has a plurality of balloons configured for inflation with a coolant fluid. Other components of the system include a luminally protective sheath, a microscopic end cauterizing probe, a surgical console, an identification-sensitive self-sealed cassette, and a plurality of flexible tubing lines with pinch valves thereon.

7. A system for treating tissue comprising:
-
a probe configured for insertion through a skin into a tissue for mechanically cutting, the probe comprising; a cutting core disposed in a housing, the cutting core having at least one sharp curved edge located in a distal region of the cutting core for cutting, the cutting core also having a channel formed therein for providing aspiration of fluid and bodily material while the sharp curved edge is cutting; a housing disposed around the cutting core, the housing having one or more openings in a distal region thereof that opens during the aspiration of fluid and bodily material; a transparent light sheath disposed around the housing, the light sheath having a plurality of grooves disposed on a surface of the transparent light sheath to provide a plurality of fluid pathways configured for conducting fluid towards a distal end of the housing while the channel of the cutting core is providing aspiration; and an opaque cover disposed around the transparent light sheath; and a device on the probe for simultaneously tamponading, inducing hemostasis, and dilating a plurality of lumens, said device including a plurality of tamponading balloons configured for inflation with a coolant fluid. - View Dependent Claims (8, 9, 10)

11. A system for treating tissue comprising:
-
a probe configured for insertion through an incision into a skin into a tissue for mechanically cutting, the probe comprising a cutting core disposed in a housing, the cutting core having at least one sharp edge located at a distal port of the cutting core for cutting, the cutting core also having a channel formed therein for providing aspiration of fluid and tissue from the distal port while the sharp edge is cutting; a surgical console for controlling aspiration through a flexible tubing line connected thereto which is in fluid communication with the cutting core channel; a pinch valve in fluid communication with the flexible tubing line for releasing aspiration in the flexible tubing line and cutting core channel so that aspired tissue may be selectively released from the distal port; a sealing device on the probe for simultaneously tamponading, inducing hemostasis, and dilating a plurality of lumens, said device including a plurality of tamponading balloons configured for inflation with a coolant fluid; a housing disposed around the cutting core, the housing having one or more openings or portals in a distal region thereof, at least one opening or portal being at least partially open at all times during the aspiration of fluid and bodily material; a grooved sheath disposed around the housing having a plurality of grooves disposed on an outer surface thereof to provide a plurality of fluid pathways configured for conducting fluid towards a distal end of the housing while the channel of the cutting core is providing aspiration; an opaque cover disposed around the grooved sheath; and a visualization system enabling external viewing of an area beyond the distal port of the cutting core. - View Dependent Claims (12, 13)
