An ophthalmological device for processing a curved treatment face in eye tissue comprises a scanner system with a plurality of scan axes configured to move the focal spot to target locations in the eye tissue. A circuit is configured control the scanner system to move the focal spot to target locations along a processing path, defined by treatment control data, to process the curved treatment face in the eye tissue. The circuit is further configured to perform a feasibility check, using the treatment control data and scan capabilities of the scanner system, defined by scan performance characteristics of each particular scan axis. In case the feasibility check indicates that moving the focal spot along the processing path exceeds the scan capabilities of the scanner system, the circuit adjusts the treatment control data.

20220387106 · 2022-12-08 ·

A catheter system (100) for treating a treatment site (106) within or adjacent to a vessel wall (108A) or a heart valve includes a light source (124), a first light guide (122A), a second light guide (122A), and an optical alignment system (257). The light source (124) generates light energy (224A, 224B, 324A, 324B, 424B). The first light guide (122A) receives the light energy (224A, 224B, 324A, 324B, 424B) from the light source (124). The first light guide (122A) has a guide proximal end (122P). The second light guide (122A) receives the light energy (224A, 224B, 324A, 324B, 424B) from the light source (124). The second light guide (122A) has a guide proximal end (122P). A multiplexer (223) directs the light energy (224A, 224B, 324A, 324B, 424B) toward the guide proximal end (122P) of the first light guide (122A) and the guide proximal end (122P) of the second light guide (122A). The optical alignment system (257) determines an alignment of the light energy (224A, 224B, 324A, 324B, 424B) relative to at least one of the guide proximal ends (122P). The optical alignment system (257) adjusts the positioning of the light energy (224A, 224B, 324A, 324B, 424B) relative to the at least one of the guide proximal ends (122P) based at least partially on the alignment of the light energy (224A, 224B, 324A, 324B, 424B) relative to the at least one of the guide proximal ends (122P).

Laser-assisted transdermal delivery of nanoparticulates and hydrogels

A laser treatment system includes a laser device configured to produce a laser beam at a wavelength in an ultraviolet spectrum to provide for tissue ablation, a lens configured to focus and direct the laser beam to a site to form an opening in a surface of the site, a valve connected to a first channel, and a nozzle that emits the laser beam and controls delivery of at least a first substance and a second substance to the site. A portion of the first channel is disposed within a first sidewall of the nozzle to deliver the first substance, and a second channel unconnected with the valve is disposed within a second sidewall of the nozzle to deliver the second substance.

Treatment using low intensity laser therapy
09782221 · 2017-10-10 · ·

Deep Tissue Low Intensity Laser Therapy or Treatment (DT-LILT) as described here is a novel methodology through which selective destruction of nociceptive (pain) nerves can be brought upon by a medical laser delivery system using the phenomenon of absorption and cell resonance. Using this method nerve cells that transmit pain can be selectively destroyed leaving the surrounding tissues intact as no heat is generated. The delivery system incorporates a fine needle through which a 703 nm (range 690 to 710) pulsed wave low intensity laser is delivered deep into the body, directly to the area of pain causing selective destruction of pain nerves. Laser devices based on this methodology should be used only by the physician or equivalent professional community since diagnosing and defining the area of pain is critical to providing successful pain relief.
