The access and RF ablation system can include an RF ablation probe, a stylet, a cannula, a needle, and a drill. The method of using the access and radio-frequency ablation system can include inserting portions of a combined stylet into a patient's body to create a pathway therethrough and position a distal end of the stylet and a distal end of the cannula adjacent hard and/or soft tissues requiring ablation or tissues adjacent thereto; pushing portions of the needle into, through, and out of an interior cavity of the cannula to position a curved distal end of the needle adjacent the distal end of the cannula in the pathway; lengthening the pathway in an angled and curved direction relative to a mid-longitudinal axis of the cannula by pushing the curved distal end portion of the needle further into the hard and/or soft tissues requiring ablation or the tissues adjacent thereto; guiding a drill using the needle to enlarge and/or further lengthen the pathway in the hard and/or soft tissues requiring ablation or the tissues adjacent thereto in an angled and curved direction relative to the mid-longitudinal axis of the cannula; pushing portions of the RF ablation probe into, through, and out of the cannula and into and through the pathway to position a distal end portion of the RF ablation probe adjacent the hard and/or soft tissues requiring ablation; and activating the RF ablation probe to ablate all or portions of the hard and/or soft tissues requiring ablation.

Electrical instrument for applying radiofrequency and/or microwave frequency energy to tissue, comprising: a distal part comprising an instrument tip for applying radiofrequency and/or microwave frequency energy to tissue, the instrument tip comprising first and second conductive elements; a coaxial feed cable comprising an inner conductor, a tubular outer conductor coaxial with the inner conductor, and dielectric material separating the inner and outer conductors, the coaxial feed cable being for conveying radiofrequency and/or microwave frequency energy to the distal part; wherein: the inner conductor is electrically connected to the first conductive element and the outer conductor is electrically connected to the second conductive element through a rotatable connection between the distal part and the coaxial feed cable that allows rotation of the distal part relative to the coaxial feed cable; and the instrument comprises an actuator for rotating the distal part in a first rotational direction relative to the feed cable.

The present disclosure relates to a bipolar catheter which enables a more precise surgical procedure by being configured to be able to evenly apply a high-frequency wave by an electrode tip being rotated inside a lesion area, and which can minimize damage to a surrounding tissue that can occur during an invasive surgery using a catheter, and which also enables a safer and more accurate surgical procedure compared to an existing surgical procedural method dependent on the medical technique of an operator, by electronically precisely controlling the position of the electrode tip within the lesion area.

An apparatus is disclosed for thermal therapy in a male prostate patient. The apparatus includes a long tubular element that is to be inserted into a patient's urethra so that a first tip end of it reaches up into the patient's diseased prostate. The elongated portion includes a narrow cylindrical tube within which an ultrasonic array is disposed along the long axis of the cylinder. Fluid is pumped into and out of a treatment zone of said patient as needed to control a temperature of a region in said treatment zone. A motorized driver is used to controllably rotate said elongated portion and the ultrasound array therein about the long axis of the apparatus so as to deliver acoustic energy to said diseased tissue. Various control and monitoring components may be used in conjunction with the present apparatus to design, control, and terminate the therapy.

An arthroscopic or other surgical system includes a handpiece and a probe. The handpiece carries a motor drive, and the probe has a proximal hub and an elongate shaft which extends about a longitudinal axis to a working end of the probe. The hub is configured for detachably coupling to the handpiece, and the motor drive is configured to couple to a rotating drive coupling in the hub when the hub is coupled to the handpiece. A first magnetic component is carried by the hub, and a second magnetic component is coupled to rotate with the rotating drive coupling.

An incision instrument includes an insertion section and a manipulation section. The insertion section includes a first insulating member and an incision section inserted within the first insulating member. The incision section includes a tubular shaped first conductive member which has conductivity; a second conductive member disposed in the first conductive member; a contact section provided on an outer circumference surface of the second conductive member; and a second insulating member fixed to a distal end of the first conductive member and having an opening section. The manipulation section includes a manipulation main body section and a handle member. The second insulating member is positioned between the contact section and the first conductive section in a state in which the second conductive member is protruded from the opening section of the second insulating member.

A tissue resecting device includes a handle, a shaft assembly movably attached to the handle, a housing secured to a distal end of the shaft, and an electrode. The electrode is disposed in the housing to move across a window, and at least one motor in the handle both reciprocates the shaft assembly relative to the handle and drives the electrode across the window.

Disclosed herein are systems and methods for locating and identifying nerves innervating the wall of arteries such as the renal artery. The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The methods includes evaluating a change in physiological parameters after energy is delivered to an arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using said method. Also provided are catheters for performing the mapping and ablating functions.

An apparatus for operating on tissue has a body, an elongate shaft, and an end effector. The elongate shaft extends distally from the body. The elongate shaft has an articulation section that is operable to selectively deflect the end effector laterally relative to the elongate shaft. The articulation section presents a first indication section and a second indication section. The first and second indication section may be configured to visually indicate the direction and degree of articulation of the articulation section. The first and second indication section may alternatively be configured to indicate the angular orientation of the end effector about the longitudinal axis. The body may further comprise a knob that is operable to rotate the shaft about the longitudinal axis. The knob may include a third indication section and a fourth indication section that align with the first and the second indication sections of the articulation section, respectively.
