The invention is a system for monitoring and controlling tissue ablation. The system includes a controller configured to selectively control energy emission from an electrode array of an ablation device based on ablation feedback received during an ablation procedure with the ablation device. The controller is configured to receive feedback data from one or more sensors during the ablation procedure, the feedback data comprising one or more measurements associated with at least one of operation of the electrode array of the ablation device and tissue adjacent to the electrode array. The controller is further configured to generate an ablation pattern for controlling energy emission from the electrode array of the ablation device in response to the received feedback data.

A cutting device for cutting a sternum of a patient comprises a laser source, a beam adjusting structure, a support and a correction arrangement. The laser source is adapted to generate a cut laser beam. The beam adjusting structure is arranged for directing the laser beam along a predefined cut geometry at the sternum. The support carries the laser source. The support has a mounting structure adapted to be fixed to a rib cage of the patient such that the laser source is in a predefined position with respect to the sternum. The correction arrangement is adapted to automatically identify a movement of the laser source relative to the sternum causing the cut laser beam to deviate from the predefined cut geometry and adjust the position of the laser source relative to the sternum to correct the deviation of the cut laser beam with respect to the predefined cut geometry.

An electrosurgical system for treating biological tissue that comprises: an electrosurgical generator to supply microwave energy; a surgical scoping device having a steerable insertion cord for insertion to a treatment site; and an electrosurgical instrument dimensioned to fit within an instrument channel that is located within the insertion cord. The electrosurgical instrument comprises: a flexible coaxial cable arranged to convey the microwave energy; and a radiating tip portion connected at an end of the coaxial cable and configured to receive microwave energy. The radiating tip portion comprises: a coaxial transmission line for conveying the microwave energy; and a needle tip mounted at an end of the proximal coaxial transmission line, wherein the electrosurgical instrument is slidable within the instrument channel to extend the needle tip beyond an end of the instrument channel to puncture biological tissue; the needle tip is arranged to deliver the microwave energy into biological tissue.

Apparatus, including a probe, containing a first lumen and a second lumen and having a distal end that contacts tissue of a living subject. A fluid supply delivers a cryogenic fluid through the first lumen to the distal end and receives cryogenic fluid returning via the second lumen. A temperature sensor is located at the distal end. A pressure sensor located at a proximal end of the first lumen measures a pressure of the cryogenic fluid. A processor controls a delivery rate of the cryogenic fluid from the fluid supply, so that, when a temperature measured by the temperature sensor is less than a preset guard temperature, the delivery sate is a preset low rate, and when the temperature measured by the temperature sensor is greater than or equal to the preset guard temperature, the delivery rate is set in response to a pressure measured by the pressure sensor.

The present disclosure is directed to ablative devices comprising biocompatible materials in the form of a mesh to provide porosity to allow for the conveyance of conductive fluid to target tissue to be ablated. The mesh also increases the durability of the biocompatible material, reducing the amount of biocompatible material needed for both reusable devices and disposable ablative devices, such as ablative forceps and ablative probes.

The invention relates to a tissue ablation system including an ablation device having a deployable applicator, preferably, with a non-spherical head configured to be delivered to a tissue cavity and ablate marginal tissue surrounding the tissue cavity. The deployable applicator head is configured to be delivered to a tissue cavity while in a collapsed configuration and ablate marginal tissue surrounding the tissue cavity while in an expanded configuration.

A mastopexy implant for maintaining the breast in an elevated and aesthetically pleasing position includes a lower pole support comprising end portions which may be affixed to the chest wall or to a previously installed upper suspension strut. The implant is loaded in an insertion device. The insertion device is inserted through a small incision and into a subcutaneous pocket created in an inferior half of the breast. The lower pole support may have various constructs and in one embodiment includes a unitary conformable mesh having a plurality of arm or band members which are attached across the breast parenchyma and to the chest wall.
