Ablation and visualization systems and methods to access quality of contact between a catheter and tissue are provided. In some embodiments, a method for monitoring tissue ablation of the present disclosure comprises advancing a distal tip of an ablation catheter to a tissue in need of ablation; illuminating the tissue with UV light to excite NADH in the tissue, wherein the tissue is illuminated in a radial direction, an axial direction, or both; determining from a level of NADH fluorescence in the illuminated tissue when the distal tip of the catheter is in contact with the tissue; and delivering ablation energy to the tissue to form a lesion in the tissue.

Combined methods for treating a patient using time-varying magnetic field are described. The treatment methods combine various approaches for aesthetic treatment. The methods are focused on enhancing a visual appearance of the patient.

A laser tip, a laser treatment tool, a laser treatment device and a laser treatment system are provided for performing laser treatment surgery and minimizing any bleeding. A laser tip is attachable to a laser radiation opening located at the tip end of a laser transmission tube. The laser tip includes an attaching portion detachable from the laser radiation opening and a contact portion contactable with biological tissue. The contact portion is at the front of the attaching portion in the direction in which the laser light exits the laser radiation opening. An open space is located between the contact portion and the attaching portion, and a coupler couples a part of the contact portion and a part of the attaching portion. The contact portion has a reflective surface at a rear end thereof which reflects the laser light toward the coupler.

[Object] There is provided .a medical laser irradiation device and a medical laser irradiation method, both of which are capable removing plaque adhering to the angioendothelium more safely using laser light. [Solution] A medical laser irradiation device according to the present disclosure includes a first laser light source configured to emit a first laser light having a wavelength band that is selectively absorbed by plaque existing inside a blood vessel of a living body; a second laser light source configured to emit a second laser light having a wavelength band that is selectively absorbed by the plaque calcified and existing inside the blood vessel; and an optical fiber configured to coaxially guide the first laser light and the second laser light, and at least a part of which is inserted into the blood vessel.

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.

Aspects of this disclosure pertain to a device with an elongated body having a distal end. The distal end may comprise a port that permits discharge of a laser energy towards a tissue from an optical fiber located in the distal end. An exterior surface of the distal end may include a cauterization portion that permits discharge of a cauterization energy towards the tissue. In some aspects, the device includes an insulative portion that attaches the distal end to the elongated body and limits energy transfer therebetween. Related systems and methods are also disclosed.
