Visualizing ablation device and procedure

InactiveUS6902526B2Prevent slippingRelieve low back painEar treatmentLaproscopesSurgical departmentTarget tissue

A medical needle set for visualized tissue ablation within a subject's body includes a cannula and components configured for inclusion in the cannula, including a trocar for occlusion of the cannula lumen during needle placement, and a visualizing ablation probe used for simultaneous endoscopic viewing and ablation of tissue sites with a laser beam. The cannula can include a tissue-gripping surface for stabilization of the needle set on the target tissue. A surgical system for tissue ablation includes a visualizing ablation needle set operably connected to an endoscope and a laser. A surgical procedure using this system permits simultaneous visualization and ablation of tissues, including those of the facet joints of the spine.

Action/counteraction superimposed double chamber broad area tissue ablation device

ActiveUS20160338752A1Easy to implementOvercome limitationsUltrasound therapyDiagnosticsEnergy transferEngineering

A non-linear ablation device includes two opposing surfaces, which are associated with two overlying and separate compartments. A first compartment of the two overlying and separate compartments is configured to emit or resorb energy. A second compartment of the two overlying and separate compartments is configured to either resorb or emit energy to oppose a direction of energy transfer of the first compartment. Other embodiments of the non-linear ablation device are further disclosed.

Microwave Device For Tissue Ablation

ActiveUS20150038956A1Good mechanical resistanceIncreased mechanical toughnessSurgical needlesSurgical instruments for heatingDielectricElectrical conductor

A microwave device for the ablation of biological tissues including a coaxial antenna, including an internal conductor, surrounded by a layer of dielectric material, an external conductor coaxial to the dielectric metal tip electrically connected to the internal conductor, and a quarter wave impedance transformer including a sleeve made of dielectric material having a proximal end covered with a layer of metal, the metal extending over nearly a quarter wavelength of electromagnetic field in the dielectric at the operating frequency of the device or of odd multiples of the quarter wavelength, the layer of metal material being connected electrically to the external conductor.
