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.

The present disclosure relates to a laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to the lens.

A catheter system for treating a vascular lesion within or adjacent to a vessel wall includes an energy source, a plurality of energy guides and a system controller. The energy source generates energy. The plurality of energy guides receive energy from the energy source. The system controller controls the energy source so that the energy is sequentially directed to each of the plurality of energy guides in an advancing wavefront. The system controller controls a firing rate of the energy source to each of the plurality of energy guides. The system controller can control a firing sequence to the plurality of energy guides so that the advancing wavefront is generated toward the vascular lesion from near the balloon proximal end and from near the balloon distal end. The system controller can control the energy source so that light energy from the energy source is alternatively directed to at least two of the plurality of energy guides at a different firing energy level from one another. The energy level can be based on pulse width, wavelength and/or amplitude of the energy pulse(s).

The present invention is directed toward a method for treating a vascular lesion within or adjacent to a vessel wall. The method includes the steps of generating energy with an energy source; receiving the energy with a plurality of energy guides; and controlling the energy source with a system controller of a catheter system so that the energy from the energy source is sequentially directed to each of the plurality of energy guides in a first firing sequence.

The method can include the system controller controlling a firing sequence to the plurality of energy guides so that an advancing wavefront is generated toward the vascular lesion from near a balloon proximal end and/or from near a balloon distal end. The system controller can control a firing energy level, which can be dependent at least partially upon the pulse width, the wavelength and/or the amplitude of the energy pulses.

A catheter system for treating a treatment site within or adjacent to a vessel wall includes a light source, a balloon, a light guide, and an optical analyzer assembly. The light source generates light energy. The balloon is positionable substantially adjacent to the vascular lesion. The balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The light guide receives light energy from the light source at a guide proximal end and guides the light energy toward a guide distal end and into the balloon interior. The optical analyzer assembly is configured to optically analyze light energy emitted from the guide proximal end of the light guide.

A method for treating a treatment site within or adjacent to a vessel wall or a heart valve, includes the steps of (i) generating light energy with a light source; (ii) positioning a balloon substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior that receives a balloon fluid; (iii) receiving the light energy from the light source with a light guide at a guide proximal end; (iv) guiding the light energy with the light guide in a first direction from the guide proximal end toward a guide distal end that is positioned within the balloon interior; and (v) optically analyzing with an optical analyzer assembly light energy from the light guide, wherein the light energy that is analyzed moves in a second direction that is opposite the first direction.

Certain embodiments of the present disclosure provide a thermally robust laser probe assembly. The probe assembly comprises a cannula through which one or more optical fibers extend at least partially for transmitting laser light from a laser source to a target location.

A light radiating device (1A) performs solidification or cauterization of a biological tissue (PL) by radiating a light beam (BM). A light source (10A) emits the light beam (BM). An optical waveguide (20A) is a member being provided with a reflection surface (21A) totally reflecting the light beam (BM) on an inner circumferential side wall, causing the light beam (BM) emitted from the light source (10A) to enter a part enclosed by the inner circumferential side wall from one end, and sending the light beam (BM) to the other end. A catoptric system (30A) reflects the light beam (BM) sent to the other end of the optical waveguide (20A) and condenses the light beam (BM) on the biological tissue (PL).

A method for assembling a plurality of optical fibers and lenses in a support structure for an ablation catheter includes providing a support structure with a proximal end, a body, and a distal end, wherein the distal end includes a plurality of alignment orifices or slits. A plurality of optical fibers are threaded through the alignment orifices or slits, such that each optical fiber is threaded through a corresponding alignment orifice or slit. An adhesive material is applied at each alignment orifice or slit to secure the optical fibers, and the plurality of optical fibers are then cleaved at the distal end to remove portions of the fibers extending out of the distal end. Finally, a lens is attached to each of the ends of the plurality of optical fibers.

A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve within a body of a patient includes an energy source, an inflatable balloon, an energy guide, and an acoustic sensor. The energy source generates energy. The inflatable balloon is positionable substantially adjacent to the treatment site. The inflatable balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The energy guide receives energy from the energy source and guides the energy into the balloon interior. The acoustic sensor is positioned outside the body of the patient. The acoustic sensor senses acoustic sound waves generated in the balloon fluid within the balloon interior. The acoustic sensor generates a sensor signal based at least in part on the sensed acoustic sound waves. A system controller receives the sensor signal from the acoustic sensor and controls operation of the catheter system based at least in part on the sensor signal.
