Abstract: A system is provided comprising a robotic instrument for use with a tool. In some versions, the robotic instrument comprises a hand-held portion to be held by a user and a tool support movably coupled to the hand-held portion to support the tool. A plurality of actuators operatively interconnect the tool support and the hand-held portion to move the tool support in three degrees of freedom relative to the hand-held portion. An optional constraint assembly may operatively interconnect the tool support and the hand-held portion to constrain movement of the tool support relative to the hand-held portion in three degrees of freedom. A guidance array assists users in positioning the tool and/or portions of the instrument.

Abstract: An aspiration system to control vacuum pressure in an ultrasonic surgical handpiece to result in improved control responsiveness during aspiration. The system comprises a console including a vacuum pump. The system includes a cassette comprising a joint that divides a vacuum path into at least two flow paths. A first joint port couples to a first flow path. A second flow path is coupled to a second joint port, a third flow path is coupled to a third joint port, and a fourth flow path is coupled to a port on a surgical waste receiver. A first sensor senses pressure in the fourth flow path and provides a waste receiver pressure signal. A second sensor senses pressure in the third flow path and provides a tip pressure signal. The controller controls a position of a first vent valve and a second vent valve based on the waste receiver pressure signal and the tip pressure signal, respectively.

Abstract: Inverting tube thrombectomy apparatus for removing clot that are configured to prevent compression of the apparatus that may separate the distal end of the apparatus from the clot and may make it difficult to advance the apparatus to engage with the clot, particularly in a tortious vessel. The apparatuses and methods of using them described herein may be adapted to prevent tension in the flexible tube that is rolling and inverting over the distal end of the inversion support catheter when capturing a clot. Also described herein are inverting tube thrombectomy apparatus that are configured to reload either automatically or manually within the vessel to capture additional clot material.

Abstract: A device (10) for collecting and processing bone fragments is disclosed. The device comprises a chamber member (12), a press member (14), an intake port (16), and a vacuum port (18). A compression surface (20) and a filter support surface (22) configured to support a filter are defined by said chamber and/or press member. The intake port is on the chamber and/or press member and is configured to receive a composition comprising bone fragments. The vacuum port is on the chamber and/or press member. The chamber member and the press member are rotationally coupled with one another. The composition is acquired through the intake port and collected between the compression surface and the filter support surface. The application of rotational force to the chamber and/or press member in a first direction moves the compression surface and the filter support surface together to compress the composition therebetween to compact, and further remove filtrate from the composition.

Abstract: A system (30) for dispensing curable material. A lead screw (62) is rotatably fixed relative to a first control surface (60) and includes external threads (94). A locking nut (90) includes internal threads (92) threadably engaging the external threads. An engagement feature (98) of the locking nut is adapted to be selectively engaged with an actuator (120) having a second control surface (122). The threads provide for rotation of the locking nut about a translation axis when the actuator is in a disengaged position. Rotation of the locking nut permits the lead screw to move proximally along the axis and the compressed curable material to at least partially decompress within a dispensing volume. The threads further provide for distal advancement of the lead screw along the axis when the actuator is in an engaged position rotatably fixing the locking nut about the axis. Methods for operating and packaging the curable material dispensing system are also described.

Abstract: A surgical system and a method of operating a surgical system are disclosed herein. The surgical system comprises a surgical console, a control device, and a dongle. The surgical console operates a surgical device and comprises a connection port. The control device communicates with the surgical console to remotely control the surgical device. The dongle physically couples to the connection port of the surgical console. The control device comprises a first communication device and a radio frequency (RF) reader, and the dongle comprises a second communication device and a passive RF device. The RF reader receives the pairing information from the passive RF device in response to the passive RF device being with a threshold proximity of the RF reader. The first and second communication devices wirelessly connect based on the pairing information, enabling the control device to wirelessly communicate with the surgical console to remotely control the surgical device.

Abstract: A thermal control unit supplies temperature controlled fluid to a patient to control the patient's temperature. The thermal control unit includes a fluid outlet, fluid inlet, heat exchanger, pump, patient core temperature probe port, auxiliary sensor port, and controller. The controller receives patient core temperature readings from the patient temperature probe port and auxiliary sensor readings from the auxiliary sensor port. The controller may control a temperature of the circulating fluid in both a feedback manner using patient core temperature readings and a feedforward manner using readings from the auxiliary sensor. The auxiliary sensor may measure a characteristic of the patient's tissue indicative of thermal resistance, and/or the auxiliary sensor may measure a temperature of the patient's tissue at an intermediate depth. The controller may use the intermediate temperature to predict arrival at a target patient temperature. The auxiliary sensor may be an ultrasonic sensor, infrared sensor, or the like.
