TARGET IDENTIFICATION WITH OPTICAL FEEDBACK SIGNAL SPLITTER
20210338325 · 2021-11-04 ·

A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

20230329786 · 2023-10-19 ·

The present disclosure relates to a fat-removing surgical instrument. The present disclosure additionally arranges/provides, on a lipolyzed fat suction passage of a wave-guide tube, an optical fiber support which is made from an insulating material and which supports optical fibers in a restrained state while fixed to the wave-guide tube, so that the optical fibers are prevented from being deformed and coming in contact with the wave-guide tube, and thus, the optical fibers are induced, even though a variety of factors (for example, weight, contact with human tissue and the like) are applied to the optical fibers during fat removal surgery, to effectively avoid coming in direct contact with the wave-guide tube and being damaged thereby, while a series of deformations (for example, a curved shape and the like) are inhibited/controlled, on the basis of forceful restraint of the optical fiber support.

METHODS AND DEVICES FOR OPTOACOUSTIC STIMULATION

A tapered fiber optoacoustic emitter includes a nanosecond laser configured to emit laser pulses and an optic fiber. The optic fiber includes a tip configured to guide the laser pulses. The tip has a coating including a diffusion layer and a thermal expansion layer, wherein the diffusion layer includes epoxy and zinc oxide nanoparticles configured to diffuse the light while restricting localized heating. The thermal expansion layer includes carbon nanotubes (CNTs) and Polydimethylsiloxane (PDMS) configured to convert the laser pulses to generate ultrasound. The frequency of the ultrasound is tuned with a thickness of the diffusion layer and a CNT concentration of the expansion layer.

Laser apparatus for treatment of a cataractous lens

An apparatus for aiding the removal of cataracts in which an optical fiber delivers sufficient optical energy of the correct wavelength, pulse duration to achieve controlled non-thermal and non-acoustic dissolution of hard cataract tissue.

LASER RESECTOSCOPE FOR MINOR CALIBER

20220331161 · 2022-10-20 · ·

A treatment probe for treating an eye of a patient includes an elongate body that defines a handle and a treatment fiber that is housed within the elongate body. The treatment fiber is configured to deliver treatment light energy to the eye. A contact member is disposed on an end of the elongate body. The contact member has a contact surface for positioning on a surface of the eye, two side edges that are positioned on opposite sides of the contact surface, and a fluid channel. The contact surface conforms to the shape of the eye's sclera and the two side edges are shaped to direct fluid that is present on the surface of the eye toward the fluid channel when the contact member is moved laterally across the surface of the eye. The fluid aggregates within the fluid channel and contacts a distal end of the treatment fiber.

Optimization of BPH treatment using LEP (laser enucleation of prostate)

Apparatus for the treatment of a target tissue with a laser beam in which the target tissue is immersed in a liquid medium within a body lumen. The laser device is configured to provide one or more laser pulses which are configured by a controller to have an energy sufficient to form one or more vapor bubbles in the liquid medium at the distal delivery end of the fiber. The one or more pulses are configured by the controller to: first, cause a vapor bubble to be formed distally of the distal end portion of the endoscope and around the distal delivery end of the optical fiber; second, cause a second bubble to be formed distally of the first bubble; and, third, inflate the second bubble as the first bubble has begun to collapse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the distal delivery end of the fiber and the target tissue.

Optical measurement device, catheter kit, and optical measurement method

A light measurement device measures the intensity of laser light output from a catheter tip end portion of a catheter having a built-in optical fiber. The light measurement device includes a light receiving part which receives the laser light output from the catheter tip end portion and a mounting part which is disposed at a position facing the light receiving part. The mounting part defines a position of a tubular hoop, which accommodates the catheter, with respect to the light receiving part. In a state in which the position of the hoop is defined by the mounting part, the light measurement device obtains the intensity of the laser light by inputting the laser light to the light receiving part.
