A method for conducting intrabody surgery by means of a surgical device having a cutting arrangement actuated by a driveshaft and rotationally supported by the guide wire. A receiving cannel extends through the cutting arrangement and movably receives the guidewire. A plurality of sensors is provided within the cutting arrangement to emit signals capable of changing parameters depending on the composition of the occlusion, so as to allow the control unit to generate signals controlling operation of the cutting arrangement. The method includes the steps of detecting parameters within the intrabody area by the sensors to controlling operation of the cutting arrangement with the power and control unit.

A tool has a handle and an elongate shaft that extends distally from the handle. A distal portion of the shaft is inserted into a subject during a surgical procedure. An optical fiber delivers laser energy to a tip at the distal portion of the shaft. The tip includes a mechanical cutting mechanism including a moving part that absorbs the laser energy, thermally conducts the absorbed energy to tissue that is disposed between the moving part and another part, and moves with respect to the other part in order to cut tissue that is disposed between the parts using a mechanical force that is lower than a mechanical force that would be required to cut the tissue in the absence of the laser energy. Other embodiments are also described.

An endoscope includes a handle including a handle housing, an irrigation inlet port adapted to receive irrigation fluid, and an irrigation channel; and an insertion cord extending distally from the handle. The insertion cord includes an insertion tube; a bending section extending from the insertion tube; a distal tip extending from the bending section and including a tip housing; a camera at least partially enclosed in the tip housing; interstitial space within the insertion tube in fluid communication with the irrigation channel; and at least one interstitial flow opening in fluid communication with the interstitial space and adapted to discharge the irrigation fluid.

Systems, devices, and methods for identifying a target in a body using a spectroscopic feedback from the target are disclosed. An exemplary surgical feedback control system comprises a feedback analyzer configured to receive a reflected signal from a target in response to electromagnetic radiation directed at a target, and a controller in operative communication with the feedback analyzer. The controller can generate a control signal to a surgical system to perform a predetermined operation based upon the received reflected signal, including determining a composition of the target, or programming a laser setting to direct laser energy to the target.

Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first office action, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.

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.

Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.

A power supply device for a high frequency treatment instrument to treat living tissue includes an output unit to supply high frequency power to the treatment instrument's electrode, a distance information acquisition unit to acquire a distance between the living tissue and the electrode, a determination unit to determine whether the distance satisfies a first condition, and an output control unit to control the output unit so that its output is placed in a controlled state if the distance satisfies the first condition and so that the output is set to a first output level higher than an output level in the controlled state if a second condition is satisfied after the output is placed in the controlled state.

A medical apparatus includes a treatment device configured to be capable of treating a subject by applying energy to the subject, an optical fiber including a light emitting face for emitting light into the subject, the optical fiber being connected to the treatment device, and a shield portion that is disposed in front of the light emitting face of the optical fiber, the shield portion being configured to expose the light emitting face when the treatment device does not perform a treatment operation and to shield the light emitting face when the treatment device performs the treatment operation.

A deflectable sheath or dilator or catheter used for cardiac procedures; it has a shaft with one or more lumens; an optical fiber for use in channeling light used for visualization of calcification, heart tissue architecture or the progress of the cardiac procedure; the sheath or dilator or catheter includes an additional optical fiber for use as part of an ultrafast laser for calcium removal on or in heart valve tissue or for performing surgical intervention of the heart, or where the optical fiber is configurable for propagating a photon beam as part of an ultrafast laser for removing calcium on or in heart valve tissue or for performing surgical intervention of the heart.
