A bone fastener comprises a first member comprising a first surface defining an implant cavity. The first member includes a first part being non-rotatable relative to the first surface and a second part including a second surface defining a portion of the implant cavity and a slot. A second member is configured to penetrate tissue and is connectable with the first member. The first member is rotatable relative to the second member in a first plane of a body and the second part is movable relative to the first part in a second plane of the body such that the first part is relatively translatable in the slot. Implants, systems, instruments and methods are disclosed.

An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

An electrosurgical instrument may comprise a pair of jaw members configured to move between an open position and a closed position. In the closed position, the pair of jaw members may be configured to exert a gripping force on material placed between working surfaces of the pair of jaw members. A first jaw member of the pair of jaw members may comprise a first electrode, and a second jaw member of the pair of jaw members may comprise a second electrode and a third electrode.

An electrosurgical probe includes an elongated shaft assembly having a proximal end, a distal end, and a longitudinal axis. A distal housing is mounted on the distal end of the shaft and optionally includes a laterally open window where a plane of the window is generally perpendicular to the longitudinal axis of the shaft. An interior channel extends axially through the shaft and further through an interior of the housing to the window in the housing. An electrode member with a serrated or other elongated edge may extend longitudinally across the window and may be configured to reciprocate the elongated edge longitudinally relative to the window.

An arthroscopic tissue resecting probe includes an elongated shaft having outer and inner sleeves which are formed from an electrically conductive material extending about an axis to a working end. Outer and inner resecting windows are formed in the sleeves in the working end. The working end includes a ceramic body having a collar portion extending fully around a region of the outer sleeve proximal to outer resecting window. A radiofrequency (RF) electrode is disposed on an outer surface of the ceramic body and is spaced-apart from the outer resecting window.

Provided are medical devices, systems and methods for retrieval and/or extraction of a corpus located in a tubular organ. Systems of this disclosure are configured for carrying out various procedures for removal of occlusive corpus from tubular organs, for example thrombectomy.

An arthroscopic cutter according to one embodiment of the present disclosure includes an elongated outer sleeve that extends about a longitudinal axis with an interior bore having an open distal end. An inner sleeve is rotatable in the interior bore in the outer sleeve. The inner sleeve carries a distal housing having a longitudinal metal member and a longitudinal ceramic member that respectively form longitudinal-extending sides of the housing around an inner channel that communicates with a negative pressure source. The arthroscopic cutter also includes an electrode that is disposed in an outer surface of the longitudinal ceramic member.

A biopsy marker may include three shaped portions arranged sequentially along an axis, each shaped portion having a first surface and a second surface parallel to the first surface. A first narrow portion connects a first of the three shaped portions to a second of the three shaped portions. A second narrow portion connects the second of the three shaped portions to a third of the three shaped portions. The first narrow portion is twisted about the axis such that the first surface of the first shaped portion is at a first angle to the first surface of the second shaped portion. The second narrow portion is twisted about the axis such that the first surface of the second shaped portion is at a second angle to the first surface of the third shaped portion.

A fluid management system includes a pump connectable to a fluid source. An inflow line removably connects to a cannula for delivering a fluid flow from the pump into a surgical site, such as a joint cavity. A flow pressure sensor is coupled to measure flow pressure in the inflow line and produce a measured pressure value, A controller is connected to the pump and the flow pressure sensor, and the controller maintains a pressure set point by controlling a pump speed based on a backpressure-adjusted pressure value calculated by subtracting a backpressure value selected from a backpressure table from the measured pressure value. The BAPV is monitored to determine whether the BAPV deviates outside an initial BAPV range, and corrective measure are taken should such deviations occur.

A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having sharp edges formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high speed to cut bone and other hard tissue. An electrode is carried in a surface portion of ceramic cutting member for cautery or radiofrequency ablation of tissue when the sleeve and cutting member are is a stationary position.
