A method for treating pelvic pain and or chronic prostatitis, and or overactive bladder symptoms. Energy, preferably in the form of infrared or near infrared wavelength light may be applied across the vaginal tissue or rectal tissue to treat pelvic pain and or chronic prostatitis. This method of energy application may cause local heating, alteration of cellular respiration, and alterations of local blood flow resulting in decreased muscle spasm, and or decreased pain, and or decreased overactive bladder symptoms. The method of the present invention may effectively treat chronic pelvic pain and or the symptoms of chronic prostatitis. The method of the invention may combine massaging of tissue with irradiation of same.

A microsurgical probe employs an optional probe support structure; an optical fiber for providing a feed path for an emission wavelength; a chemical feed path for delivering a chemical; a resonator motor; and a probe accessory tool. A microsurgical system additionally employs a sensor and an artificial intelligence (AI) system to assess conditions based on data provided by the sensor. The system can be employed to remove tumor tissue that is interwoven with healthy tissue. This system can also be employed to fertilize old, inflexible ova.

A method for displaying real-time ablation growth projections is provided. The method includes applying, by a processor, an ablation model to image data of a patient. The ablation model is based on a position of an ablation probe, and the ablation probe is coupled to the processor. The method also includes displaying, on a display coupled to the processor, a projected ablation zone on the image data. The projected ablation zone is based on ablation parameters and the position of the ablation probe. The projected ablation zone includes a margin showing a confidence level. The method further includes ablating by the ablation probe. The ablating is based on an evaluation of the projected ablation zone with respect to a target. A system for performing a microwave ablation procedure is provided. A non-transitory computer-readable storage medium storing instructions is provided.

A medical apparatus includes a probe configured for insertion into a body of a patient and comprising a plurality of electrodes configured to contact tissue within the body. The medical apparatus further includes an electrical signal generator configured to apply between one or more pairs of the electrodes sinusoidal radio-frequency (RF) signals of first and second types in alternation. The signals of the first type have a first voltage sufficient to cause irreversible electrophoresis (IRE) in the tissue contacted by the electrodes and a first power that is insufficient to thermally ablate the tissue, and the signals of the second type have a second power sufficient to thermally ablate the tissue contacted by the electrodes and a second voltage that is insufficient to cause IRE in the tissue.

The present invention enables fabrication and mass production of a bubble-jetting chip that includes a desired number of bubble jetting portions of the same size having bubble-jetting outlets of the same size. Mass production is enabled by fabricating a bubble-jetting chip comprising a substrate and a bubble-jetting portion formed on the substrate, the bubble-jetting portion comprising: an electrode that is formed of a conductive material; an insulating portion that is formed of an insulating photosensitive resin, is provided so as to sandwich the electrode, and includes an extended section that extends beyond the tip of the electrode; and a space that is formed between the extended section of the insulating portion and the tip of the electrode.

A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be 0 into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

A catheter has a distal assembly with at least one loop with ring electrodes. A single continuous puller wire for bidirectional deflection is pre-bent into two long portions and a U-shape bend therebetween. The U-shape bend is anchored at a distal end of a deflectable section which is reinforced by at least one washer having at least two holes, each hole axially aligned with a respective lumen in the deflectable section. Each hole is centered with a lumen so that each puller wire portion therethrough is straight and subjected to tensile force only. A proximal end of the support member is flattened and serrated to provide a better bonding to the distal end of the deflectable section.

A robotic surgical arm includes a puck containing motors to drive an end effector. A tool assembly attached to the puck generates ultrasonic and/or radio frequency energy to apply to tissue disposed between the jaws of the end effector. The tool assembly can include modular components such as a modular shaft that can include an ultrasonic transducer, nonvolatile memory, wireless interface, and/or a power source. The power source allows the modular shaft to communicate wirelessly with the robotic arm. The tool assembly can be moved from one robotic arm to another while remaining powered by the power source. The tool assembly can include sensors to determine a location or movement of the tool assembly after being detached from the robotic surgical arm. The modular shaft can be moved from a robotic arm to a handle manually controlled by a surgeon and back again to the robotic arm.

Techniques for High-Frequency Irreversible Electroporation (HFIRE) using a single-pole tine-style internal device communicating with an external surface electrode are described. In an embodiment, a system for ablating tissue cells in a treatment region of a patient's body by irreversible electroporation without thermally damaging the tissue cells is described. The system includes at least one single-pole electrode probe for insertion into the treatment region, the single-pole electrode probe including one or more tines. The system further includes at least one external surface electrode for placement outside the patient's body and configured to complete a circuit with the single-pole electrode probe. The system also includes a control device for controlling HFIRE pulses to the single-pole tine-style electrode and the skin-surface electrode for the delivery of electric energy to the treatment region. Other embodiments are described and claimed.
