The medical device control apparatus using the handpiece motion comprises a handpiece which is connected with a medical device body to perform a procedure; a gesture detector which is provided in the handpiece and detects the motion of the handpiece to recognize the gesture of the handpiece; an alarm unit which alarms that a mode of the medical device body is changed from a first state to a second state or parameter values are controlled according to the gesture of the handpiece; control switch which is provided in the handpiece to change the mode of the medical device body or control the parameter values output by the medical device body; and a connection cable which connects the medical device body and the handpiece.

A fractional handpiece and systems thereof for skin treatment include a passively Q-switched laser assembly operatively connected to a pump laser source to receive a pump laser beam having a first wavelength and a beam splitting assembly operable to split a solid beam emitted by the passively Q-switched laser assembly and form an array of micro-beams across a segment of skin. The passively Q-switched laser assembly generates a high power sub-nanosecond pulsed laser beam having a second wavelength.

A system for creating separation between biological surfaces may comprise a hollow body configured for delivery of a fluid to a target location, a fluid supply in fluid-communication with the hollow body, a control element configured to control the delivery of a fluid through the hollow body, at least one first sensor configured to measure at least one parameter of the fluid flowing through the hollow body, at least one second sensor configured to measure at least one parameter of an environment of the hollow body, a feedback control module configured to receive information from one or more of the at least one first sensor or the at least one of the second sensor to control at least one operational function of the system.

A treatment apparatus includes a motorized subsystem in a handpiece housing having a rotating output shaft, an axial cam driven in rotation by the output shaft, and a push rod linearly driven by the axial cam. A cartridge is removably attachable to the handpiece housing and includes a cartridge housing, a needle assembly, a piston in the housing engaging the needle assembly and linearly driven forward by the push rod, and a first biasing member urging the piston rearward.

The present invention relates to a pathology treatment apparatus comprising: an ultrasound generator device (1), a remote control unit (2) for delivering electricity to the device (1) during at least an activation cycle and determining and controlling the operating parameters thereof, each activation cycle (50) being preceded by a standby cycle, means (31, 32) of electrical connection between the device (1) and the control unit (2), notable in that the control unit (2) is programmed to detect a fault with the electrical connection between the device (1) and the said control unit (2) during at least a standby cycle.

An in vivo temperature control system has a monitor for the internal temperature of a biological organ such as the esophagus, and for directly controls the temperature in the organ side depending on the monitoring. The in vivo temperature control system includes: a catheter insertable into a living body; a temperature probe containing a temperature sensor, the probe being insertable into the catheter; a liquid storage section for storing a temperature-controlled liquid; a pump for supplying the liquid from the liquid storage section to the catheter; and a control section for controlling driving of the pump based on a signal detected from the temperature probe; wherein the control section controls the pump when the signal has reached a preset threshold, and the pump is driven such that the liquid in the liquid storage section is released to the outside through the catheter.

A surgical instrument includes a housing having an elongated shaft extending distally from the housing and configured to support an end effector assembly at a distal end thereof. The end effector assembly including first and second jaw members, each jaw member including a tissue sealing plate disposed thereon. A force gauge is disposed on one or both the tissue sealing plates of the first and second jaw members. The force gauge is configured to measure a force associated with the one (or both) tissue sealing plate and communicate the force measurement to an electrosurgical energy source. The electrosurgical energy source is configured to correlate the force measurement to an amount of tension on tissue disposed between the first and second jaw members and alert a user if the amount of tension falls outside a particular range.

A surgical instrument includes a housing having an elongated shaft extending distally therefrom and configured to support an end effector assembly at a distal end thereof. The end effector assembly includes first and second jaw members each having a tissue sealing plate disposed thereon and adapted to connect to an electrosurgical energy source for delivery thereto upon activation thereof. A sensor is disposed on one (or both) of the tissue sealing plates and is configured to communicate data relating to tissue disposed between the first and second jaw members to the electrosurgical energy source for correlation to a resonance frequency of the tissue. The resonance frequency of the tissue, in turn, is used to adjust one or more parameters associated with the delivery of electrosurgical energy to the tissue upon activation thereof.

An intravascular catheter for nerve activity ablation and/or sensing includes one or more needles advanced through supported guide tubes (needle guiding elements) which expand to contact the interior surface of the wall of the renal artery or other vessel of a human body allowing the needles to be advanced though the vessel wall into the extra-luminal tissue including the media, adventitia and periadvential space. The catheter also includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened needles are advanced to penetrate into the vessel wall. Electrodes at the distal ends of the guide tubes allow sensing of nerve activity before and after attempted renal denervation. In a combination embodiment ablative energy or fluid is delivered to ablate nerves outside of the media.

Example electrosurgical devices and systems are disclosed. An example electrosurgical device includes a body, an electrosurgical electrode secured to the body, the electrosurgical electrode including a distal tip. The electrosurgical device also includes a shroud translatable relative to the electrosurgical electrode between a first position and a second position, a first magnetic component which is operably connected to the body, and a second magnetic component which is operably connected to the shroud, wherein the first and second magnetic components magnetically interact to releasably maintain the shroud in the first position.
