In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.

A device for applying radiofrequency energy for sphincter treatment comprising a flexible outer tube, an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, and a plurality of electrodes movable with respect to the arms from a retracted position to an extended position. An advancer is slidably disposed within the outer tube to move the plurality of electrodes to the extended position. An actuator moves the advancer from a first position to a second position to advance the plurality of electrodes. An aspiration tube extends within the outer tube. An assembly includes an aspiration disabler having a first position to enable aspiration from a distal portion of the aspiration tube to a proximal portion and a second position to disable aspiration.

Devices, systems, and methods to generate a plan for an interstitial laser ablation procedure are disclosed. The systems may be configured as an interstitial optical mapping system including a catheter, an emitter optical fiber, an imaging optical fiber, a light source, and a processing unit. The emitter optical fiber and the imaging optical fiber are used to interstitially image a fluorescent dye associated with a tumor, including the tumor margin, at discrete imaging positions along a length of the catheter. The processor calculates a location of the fluorescent dye at each discrete position and creates an optical map representing the tumor. The optical map is used to generate an interstitial laser ablation plan that includes laser fiber pull-back positions.

Catheter systems, tools and methods are disclosed for the selective and rapid application of DC voltage pulses to drive irreversible electroporation for minimally invasive transurethral prostate ablation.

The needle assembly includes a distal portion, a proximal portion, and a junction member disposed between the distal portion and the proximal portion. The junction member includes a recess defined therein. The needle assembly also includes a rectifier element disposed in the recess. The rectifier element includes a first terminal electrically coupled to the distal portion and a second terminal electrically coupled to the proximal portion.
