Abstract: A medical device may include a handpiece having a housing and a drive system arranged within the housing. The drive system may be adapted to operate a tool in direct contact with human matter of a patient at a treatment site. The device may also include a suction system integrated into the drive system and configured to remove human matter from the treatment site. The device may also include a motor removably attached to the housing and configured for delivering rotational power to the drive system while avoiding contact with the human matter.

Abstract: A handheld surgical instrument having a handpiece and a shaft extending from the handpiece is provided. The instrument includes a cutting implement disposed at a distal end of the shaft and an articulation portion disposed proximate to the cutting implement. The articulation portion includes a set of first slits and a set of second slits opposite the first set of slits. The articulation portion also has first and second passageways disposed in the slits along with first and second flat pull wires disposed in the passageways. The instrument also has an articulation control assembly that includes an articulator having first and second anchor points coupled with the first and second flat pull wires. The articulator moves the first flat pull wire in a first direction and moves the second flat pull wire in a second direction opposite the first direction during actuation.

Abstract: The present disclosure includes, among other things, a surgical forceps device and system. The device can include first and second opposing jaws with correlating jaw flanges meeting at a pivot point, and a distal wire guide situated within the device proximal of the jaw flanges. Wiring can run on an outside surface of the jaws, through the distal wire guide, and be routed internally as the wiring extends proximally down the device. The wire guide can act as a spacer to help guide the wiring in the device.

Abstract: Electrosurgical devices that reduce surgery time while still adhering to surgical standards are provided. An electrosurgical device can include a tripolar configuration. A primary electrode can be used to generate a vapor pocket. A secondary electrode can be activated after the vapor pocket is generated. The vapor pocket can be steered to be between the primary and secondary electrodes and a surgery target.

Abstract: A one-way lung valve for sealing fluid passageways in ventilatory airways. The valve includes a frame and a flexible membrane having respective opposed inner and outer surfaces and is supported by the frame. The flexible membrane is configured to transition between a compressed configuration and an occluding configuration in the ventilatory airways. The respective opposed inner and outer surfaces includes one or more features on the inner and/or outer surface to prevent the flexible membrane from forming one or more air gaps when the flexible membrane is in the occluding configuration position.

Abstract: Systems, devices, and methods for automatic control of laser treatment of target structure in a body of a subject based on acoustic feedback in response to delivery of laser energy to the target are disclosed. An exemplary laser energy delivery system comprises a laser system to direct laser energy at a body target, and a controller circuit to receive an acoustic signal in response to delivery of laser energy to the target, and to measure acoustic properties from the acoustic signal. The control circuit may generate control signals for controlling the laser system to adjust laser energy output, or for controlling an actuator to adjust a position of a laser fiber distal end relative to the target to achieve a desired therapeutic effect.
