Irrigated surgical guides and methods of manufacturing the same
Provided herein are surgical guides with internal channels for irrigation cooling. In one embodiment, an apparatus for guiding a surgical instrument includes a proximal side and a distal side. A first channel is configured to guide a material removal device, where the first channel extends from the proximal side of the apparatus to the distal side of the apparatus. A second channel configured to direct irrigation fluid, where the second channel extends from the proximal side of the of the apparatus to the distal side of the apparatus. The first channel is separate from the second channel. A method of performing a surgical procedure and a method of manufacturing a surgical guide are also disclosed. In certain embodiments, the surgical guides may be manufactured via additive manufacturing processes, including for example, three-dimensional printing processes.
PATIENT INTERFACE DEVICES AND METHODS AND SYSTEMS FOR COMBINED SONIC AND LASER APPLICATIONS

A pin, clip and ridge configuration for holding a window and maintaining an open reservoir of BSS in a PID. A PID for integrated systems and methods for performing laser and phacoemulsification operations. A PID for a reconfigurable system for performing a laser procedure in a laser configuration, and then being reconfigured into a phaco configuration, to perform a phacoemulsification, and then being reconfigured back to the laser configuration.
DEVICES, ASSEMBLIES, AND METHODS FOR REMOVAL OF A BODILY MASS
The present disclosure relates generally to devices, assemblies, and methods for removing a bodily mass from a body cavity. In some embodiments, a medical device may include a scope including a working channel and a sheath having a wall defining a lumen, wherein the sheath extends beyond a distal end of the scope. The medical device may further include a laser extending through the working channel, adjacent the sheath.
Hybrid laser cutter
A tool has a handle and an elongate shaft that extends distally from the handle. A distal portion of the shaft is inserted into a subject during a surgical procedure. An optical fiber delivers laser energy to a tip at the distal portion of the shaft. The tip includes a mechanical cutting mechanism including a moving part that absorbs the laser energy, thermally conducts the absorbed energy to tissue that is disposed between the moving part and another part, and moves with respect to the other part in order to cut tissue that is disposed between the parts using a mechanical force that is lower than a mechanical force that would be required to cut the tissue in the absence of the laser energy. Other embodiments are also described.
Laser energy delivery devices including distal tip orientation indicators
A laser ablation catheter includes a distal tip, and the distal tip includes a body that defines a longitudinal axis. A first orientation indicator is formed on the body, and a second orientation indicator is formed on the body. The second orientation indicator is disposed relative to the first orientation indicator such that when the distal tip is viewed in a first side view, the second orientation indicator and the first orientation indicator overlap and visually contrast with the body. A third orientation indicator is formed on the body, and the third orientation indicator disposed relative to the second orientation indicator such that when the distal tip is viewed in a second side view, the third orientation indicator and the second orientation indicator overlap and visually contrast with the body. The second side view and the first side view are substantially 90 degrees apart about the longitudinal axis.
SURGICAL DEVICE, LASER SURGERY SYSTEM, AND METHODS OF OPERATION THEREOF
Surgical devices and methods of operation thereof are provided herein. The surgical devices include interior walls defining a cavity that extends along a first axis and having an aperture at a first end of the surgical devices. The surgical devices include a backstop spaced apart from the aperture and having a surface opposing the aperture. The surgical devices include an arm that extends from the surgical device. The surgical devices are configured to receive a fiber waveguide into the cavity at a second end. The surgical devices of some embodiments include a surface for reflecting laser light from the fiber waveguide.
Minimally invasive treatment device for tissue resection
Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.
NON-SURGICAL SYSTEM FOR THE RETRACTION OF A PATIENT'S EYELID TISSUE, THAT CAN BE COUPLED TO ANY LASER GENERATOR
The invention relates to a non-surgical system for the retraction of the eyelid tissue of a patient meant to tighten the tissue without making an ablation, that is designed to be coupled to any laser generator equipment present in the market and wherein the laser generator supplies a laser beam in continuous mode to a handpiece.
The invention also relates to said handpiece.
The system is characterised by comprising a handpiece that can be coupled to a laser generator operating in a power range of 0.1 to 10 W and with treatment times of 0.1 to 5 s, and having one or more lenses that focus or collimate the laser beam to a small spot with a diameter of 0.5 to 5 mm. The system also comprises a timed pedal assembly with an electronic control unit associated with a timed pedal meant to compensate the delay time (t.sub.r) of the mechanical shutter and add it to the programmed emission time on the skin (t.sub.p), thereby compensating said delay time (t.sub.r) and allowing to obtain compensated laser beam pulses (t.sub.c), as well as incorporating a timed module to allow obtaining the required laser beam pulse times of 0.1 to 5 s.
DERMATOLOGICAL SYSTEMS AND METHODS WITH HANDPIECE FOR COAXIAL PULSE DELIVERY AND TEMPERATURE SENSING
Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first optical path, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.
Apparatus for selective treatment of tissue
A method includes depositing within a predetermined region of a target tissue with a plurality of dopant particles. The method also includes focusing a laser beam to a focal region that overlaps with at least a portion of the predetermined region. The focal region includes at least a first dopant particle of the plurality of dopant particles. The method further includes adjusting a first parameter of the laser beam to generate plasma within a plasma volume comprising the first dopant particle.
