Proposed is a filter fixing module mounted to a handpiece cooling device having a connecting unit such that a refrigerant supply unit is coupled thereto, the filter fixing module including a body having a support surface formed in a plate shape, and a receiving surface formed on an edge of the support surface and protruding in a first direction relative to the support surface so as to prevent removal of a filter received in the support surface, and a grip unit connected to the body, wherein the grip unit comprises a first grip member and a second grip member extending in directions opposite to the protruding direction of the receiving surface relative to the body.

A method and system for lesion formation assessment in tissue that has undergone an ablation procedure. In one embodiment, a method of assessing lesion formation comprises: recording a baseline impedance measurement from an area of tissue with a medical device; ablating the area of tissue with the medical device; recording a post-treatment impedance measurement from the area of tissue with the medical device; identifying at least one amplitude characteristic of the baseline impedance measurement and identifying at least one amplitude characteristic of the post-treatment impedance measurement; comparing the at least one amplitude characteristic of the baseline impedance measurement and the at least one amplitude characteristic of the post-treatment impedance measurement; generating an indication of efficacy based on the comparison, the indication of efficacy being one of sufficient lesion formation and insufficient lesion formation; and re-ablating the area of tissue if the indication of efficacy is insufficient lesion formation.

Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and/or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.

A method of performing bariatric surgery using a robotic surgical system includes positioning a gastrectomy device in a selected location in a stomach; applying an adherent material to the stomach along a desired transection line; and cutting the stomach along the desired transection line delineated by the adherent material.

A method of manufacturing a catheter tip by electroplating a conductive material over an insert comprising a negative to a domelike shape thereby forming a shape of the catheter tip comprising a dome with the domelike shape, selectively positioning a plurality of irrigation holes between outer and inner surfaces of the catheter tip, removing the insert thereby leaving the catheter tip and the plurality of irrigation holes, and electropolishing the catheter tip. In other examples, the insert is not removed and instead the step of electroplating causes the insert to be encapsulated with the conductive material thereby forming the catheter tip.

A catheter system for ablation of tissue around a blood vessel, e.g., the pulmonary artery, to reduce neural activity of nerves surrounding the blood vessel. The catheter system includes an elongate shaft having a proximal portion coupled to a handle, and a distal portion. The distal portion includes a transducer and an expandable anchor, which may be actuated to transition between a collapsed delivery state and an expanded deployed state where the anchor centralizes the transducer within the blood vessel. The transducer may be actuated to emit energy to reduce neural activity of the nerves surrounding the blood vessel. Systems and method are further provided for confirming that neural activity of the nerves surround the blood vessel has been sufficiently reduced.

Apparatus, systems, and methods provide access to the renal pelvis of a kidney to treat renal nerves embedded in tissue surrounding the renal pelvis. Access to the renal pelvis may be via the urinary tract or via minimally invasive incisions through the abdomen and kidney tissue. Treatment is effected by exchanging energy, typically delivering heat or extracting heat through a wall of the renal pelvis, or by delivering active substances.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

An optical probe includes: an optical fiber; a reflecting portion; and a traveling direction changing portion changing a traveling direction of a laser beam of a first wavelength that has transmitted through the reflecting portion to a direction different from a traveling direction before transmitting through the reflecting portion. Further, the traveling direction changing portion is configured by a bending structure having a structure in which a portion on a distal end side of the optical fiber is bent, and the reflecting portion is provided closer to a proximal end side of the optical fiber than the bending structure.

An apparatus includes a balloon adapted to be placed adjacent a calcified region of a body. The balloon is inflatable with a liquid. The apparatus further includes a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the calcified region adjacent the balloon. The shock wave generator includes a plurality of shock wave sources distributed within the balloon.
