Abstract:
The present disclosure relates to a methods and systems for high speed laser surgery. In some implementations, the combination of mid-infrared (mid-IR) laser radiation with micro-scanning technology allows for large tissue ablation rates with minimal thermally affected zones, where micro-scanning distributes the heat generated by laser surgery over a large tissue area. Micro-scanning technology is compatible with hollow core fiber technology which can be implemented to deliver near diffraction limited mid-IR laser beams into the vicinity of the target area. Micro-scanning technology is compatible with hand tools for direct replacement of mechanical surgical tools such as scalpels as well as robotic surgery. Micro-scanning technology is also compatible with endoscopic beam delivery and can be combined with endoscopic tissue analysis. Tissue analysis can be performed with optical imaging technology as well as other analytical tools such as mass spectrometers.
Abstract:
Catheter systems of the invention are directed to the removal of occlusions, such as thrombi and plaque, within blood vessels. In certain aspects, catheter systems of the invention include an elongate body defining a first lumen and comprising a distal portion, an inner member configured for insertion into the first lumen, the inner member comprising an energy source configured to deliver therapeutic energy to a treatment site; and a cooling element coupled to the energy source. The cooling element may include a heat sink, a thermoelectric cooler, or combination thereof.

Abstract:
The present invention relates to a portable endoscope system and, more specifically, to an endoscope system having a handle and a probe detachably provided at the handle, comprising: a lighting unit using an LED as a light source such that a light irradiates towards a front side thereof; an imaging unit for forming an image of the forward light irradiated by the lighting unit so as to display the image on an external imaging apparatus; and a laser unit for carrying out treatment on an affected part displayed on the imaging unit, wherein the lighting unit, the imaging unit, and the laser unit are provided to be integrated with the handle. According to the present invention, since there is no need for a separate external imaging apparatus except for a monitor or the like, the endoscope system can be used regardless of the location and is easy to carry. Furthermore, the endoscope system is manufactured in a compact shape and size, thereby providing a functional effect for facilitating the operation thereof.
Abstract:
Catheters for ablation and removal of occlusions from blood vessels are provided. Laser cutting systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Pulsed aspiration systems are provided operable to remove ablated, cut, or dislodged material without excessive or unnecessary removal of blood and fluid. A helical or partially-helical inner surface structure is provided in the catheter operable to remove dislodged material. Distal features of the catheter devices comprise arrangements of laser ablative or mechanical cutting features that generally provide enhanced surface areas and cutting functions. Spiral or helical arrangements are provided to aid in cutting operations. Catheter systems comprise distal end features adapted to cut and remove at least portions of an occlusion that generally correspond to dimensions of an inner lumen of a catheter.
Abstract:
A catheter for debulking of an undesired deposit from an inner surface of at least one of a blood vessel wall and a stent located in a blood vessel, the catheter having a tip section comprising: circumferentially-directed laser optics; and a circular-action cutter, wherein said circumferentially-directed laser optics is configured to transmit laser radiation for modifying an area of the undesired deposit thereby preparing said area for penetration of said cutter, wherein said cutter is configured to cut through said modified area and thereby debulk at least a part of the undesired deposit. In addition, a catheter for pacemaker and ICD (Implantable Cardioverter Defibrillator) lead extraction is disclosed.
Abstract:
The present invention is directed to techniques in the field of surgical systems, devices, and methods of use for skin reduction, tightening, or excision, and more particularly, to methods, systems, and devices for removing skin in tissue reduction laser surgery for the removal of skin wrinkles, laxities, or the like with minimal scarring after healing. The systems, devices, and methods of the present invention are adapted to control laser light energy to irradiate tissue such that the laser reduces, such as through vaporization, tissue in laser surgery. The present systems are adapted to use at least one laser device in conjunction with conventional and novel excision array shaping means, fiber optic light guides, distribution cylinders, stepping motors, computer programs, surgical techniques or the like therefor.
Abstract:
A multiple target ophthalmic surgery instrument is comprised of a single primary optic fiber that transmits laser light to the instrument, and a plurality of additional optic fibers that receive the laser light from the primary optic fiber and project the laser light as a plurality of beams from the plurality of additional optic fibers. In this manner, the instrument splits the single laser light beam received from a single laser light source into the multiple of laser beams and targets the multiple laser beams at multiple spots of a surgical site in the eye.
Abstract:
A system and method for treating target tissue including a light source for generating a beam of light, a plurality of optical fibers, a deflection device configured to selectively deflect the light beam into the input ends of the optical fibers, one optical fiber input end at a time, and a probe having a tip with the output ends of the optical fibers and configured for insertion into target tissue. The probe tip is configured to sequentially project spaced apart spots of the light beam from the output ends as the deflection device deflects the light beam into the optical fibers. One or more moving or static deflecting optics at the probe tip can 0 be used to statically or dynamically deflect the beam exiting the optical fibers.
