A method and apparatus that reduces the time and trauma associated with tissue removal procedures such as Ultrasound Assisted Liposuction, which emulsifies and then extracts unwanted adipose from a patient's target zone. Emulsification and suction are optimized and performed in a synchronous manner by a single apparatus to improve the outcome and minimize, if not eliminate, the limitations, risks and complications caused by current state of the art techniques.

A temperature sensing system for an electrosurgical instrument able to detect temperatures internal and/or external to the electrosurgical instrument. Temperatures detected by a temperature sensor are processed by a monitoring module which prompts action to reduce temperatures where appropriate. The temperature sensing system is particularly useful for electrosurgical instruments which combine rotary shaver arrangements and RF electrode arrangements, where suction is used to remove RF heated saline from the surgical site. Without monitoring the temperature of the electrosurgical instrument and/or the surgical site, there is a risk of burning the patient if the RF heated saline becomes too hot as the electrosurgical instrument may not be adequately insulated.

An energy source is offset from an elongate probe axis with an extension. The amount of offset of the energy source can be controlled by varying an amount of offset of the extension. The energy source rotated and translated at the offset distance to resect tissue. In some embodiments, the probe is configured to receive a second treatment probe comprising a second energy source, in which the second energy source is rotated and translated relative to the first treatment probe, which can improve positional accuracy and stability. The energy source and the extension can be coupled to a linkage to offset the energy source, and to translate and rotate the energy source with varying amounts of offset. The linkage can be coupled to a processor and one or more of the energy source moved in accordance with a treatment profile.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

A cooling radiofrequency ablation probe for delivering electrical and thermal energy to tissue of a patient's body is provided. The probe comprises a handle having an upper portion, a lower portion, and a Luer connector. The probe further comprises an extended electrocap assembly interfacing with one end of the handle, and a cable-tubing assembly interfacing with another end of the handle. The cable-tubing assembly includes an electrical cable that terminates at an electrical connector and a dual-lumen fluid tubing that terminates at inlet and outlet fluid connectors. An active tip of the extended electrocap assembly is configured to deliver the electrical and thermal energy to the tissue of the patient's body.

Medical devices such as osteotomes are provided. The medical device may include inner and outer members that form a working end portion. Distal end portions of the inner and outer members can cooperate to allow deflection of the working end portion. Medical devices including indicators are also provided. The indicator may communicate a direction of deflection of the working end portion to a practitioner. Additionally, medical devices including torque release mechanisms are provided. The torque release mechanism may uncouple a first portion of the medical device from a second portion of the medical device when an amount of torque applied to the medical device exceeds a predetermined value. The torque release mechanism may limit damage to components of the medical device during use of the medical device.

An electrosurgical device including the disclosure describes an electrosurgical device including an elongated body having a tubular section extending from a proximal end to a distal end and defining an evacuation channel configured to evacuate tissue from the distal end to the proximal end, a curette at the distal end of the tubular section, wherein the curette defines a perimeter cutting edge that forms a distal opening to the evacuation channel, a plasma cutting electrode defined by the perimeter cutting edge of the curette, where the plasma cutting electrode is configured to operate in a monopolar configuration to deliver radio frequency (RF) plasma energy to adjacent tissue to cut a volume of the target tissue, and a dielectric coating on at least a portion of the curette, the dielectric coating electrically insulating the curette from target tissue and the volume of cut target tissue, wherein the dielectric coating comprises a ceramic material.

An ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil. The ultrapolar electrosurgery blade has a non-conductive planar member with opposing planar sides, a cutting end, and an opposite non-cutting end, first active and return electrodes located on one opposing planar side, and second active and return electrodes located on the other opposing planar side.

A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.

A precision forward-looking image-guided diagnostic and therapeutic surgical probe and needle insert for microsurgery in support of imagery, neurology, neurosurgical procedures, and ophthalmic surgical applications comprising an introducer needle (stylet), a fiber carrier, a therapeutic conduit, and a spirographic method for scanning a target and associated algorithms to create and render a reconstructed image for display to a physician in real-time or near real-time. The probe implements Optical Coherence Tomography (OCT) to provide high-resolution extended imagery of an intended therapeutic or target tissue. A separate therapeutic conduit provides surgical access for therapeutic devices such as a cutting or ablation laser, an RF electrode for locally heating tissue, a lumen for local injection of neurolytics/paralytics, placement of electrodes for neuromodulation, and deployment of a micro-endoscopic imaging tool. A third working channel supports the delivery of neurolytic and other fluids.
