A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measurable when filtered, and delivering a portion of the tissue back into the patient without the need to directly touch the tissue. During the same surgical procedure, the tissue can be mixed with a biocompatible agent before introduction into the repair site.

Tissue collection and delivery device and methods of use thereof

A surgical system for controlling fluid pressure during a surgical procedure is provided. Example systems include an inflow pump coupled to a fluid source and defining an outlet port. An inflow cannula is coupled to the outlet port of the inflow pump and includes a barcode disposed thereon. An endoscope extends from a proximal end to a distal end and includes a shaft. A camera is coupled at the proximal end of the endoscope and provides visualization of a surgical site through the shaft and output a corresponding imagery signal. A pump control unit is coupled to the inflow pump and controls an outlet pressure of the inflow pump. A camera control unit is coupled to the camera and to the pump control unit and receives the imagery signal and decodes the barcode and conveys information indicative of a pressure loss across the inflow cannula to the pump control unit.

Cannula identification for use with fluid management

A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measureable when filtered, and delivering a portion of the tissue back into the patient without the need to directly touch the tissue. During the same surgical procedure, the tissue can be mixed with a biocompatible agent before introduction into the repair site.

A surgical system includes a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument defines a second channel. A valve coupled to the first instrument controls fluid flow through the first channel, such that impedance of fluid flow through the first channel is substantially the same without the second instrument received in the first channel and with the first channel partially blocked by the second instrument. In another aspect, a surgical apparatus includes an outer member and an inner member received within the outer member to define a first channel therebetween. The inner member houses an optical lens and defines a second channel for receiving a surgical instrument. The first and second channels are configured such that a pump having an inflow rate of up to about 0.7 L/min connected to the second channel can maintain fluid pressure inside an organ.

Tissue resecting system

A system for treating tissue includes a device including a first member and a second member arranged to move relative to the first member to treat tissue. The system also includes a processor configured to automatically control movement of the second member relative to the first member using position control methodology. A method of treating tissue includes providing a device having a first member and a second member arranged to move relative to the first member, moving the second member relative to the first member, and automatically controlling the movement of the second member using position control methodology.

Powered surgical system

A fluid flow device includes a housing configured to releasably mate with a surgical control unit for controlling fluid flow during a surgical procedure. First and second ports measure fluid pressure within a fluid path provided within the housing. The fluid flow device includes a restrictor for restricting fluid flow at a restriction location along the fluid path. The first port is located upstream of the restriction location and the second port is located downstream of the restriction location. A fluid pump is provided within the housing.

Surgical fluid management

A dual function arthroscopic blade provides multiple cutting surfaces of differing cut aggressiveness for selective engagement of the desired cutting blade without retracting the instrument for changing cutting members to apply a different set of cutting edges, or blade. An inner rotating member within a stationary outer cutting member provide cutting edges defined by cutting windows on the inner and outer cutting members, and a rotational drive applies an oscillating rotation such that one of the cutting windows, corresponding to one of the sets of cutting edges, engages an extraction region such as tissue or bone. The use of different sized cutting windows allows variance in the aggressiveness of the cut, and allows selection of another cutting window by rotating the cutting member to align the selected cutting edges without requiring extraction and reinsertion in order to attach a different blade with a different cut aggressiveness.
