  • Patent number: 11103657
    Abstract: Systems and methods for reducing pathogens near an implant are discussed. In some cases, the methods include reducing contaminants in a portion of a patient that has an implant and that is disposed interior to a closed surface of skin of the patient. The method can further include placing a conduit in the closed surface of skin and flowing an antimicrobial fluid into that portion of the patient to contact the antimicrobial fluid with a surface of the implant and tissue adjacent to the implant. In some cases, the antimicrobial fluid is then removed from the portion of the patient having the implant. As part of this method, biofilm near the implant can be mechanically, ultrasonically, electrically, chemically, enzymatically, or otherwise disrupted. Other implementations are described.

  • Patent number: 10959771
    Abstract: Aspects of the present disclosure are presented for a single surgical instrument configured for grasping tissue, performing sealing procedures using electrosurgical or ultrasonic energy, suctioning fluid, and providing irrigation. An end effector of the surgical instrument may include multiple members arranged in various configurations to collectively perform the aforementioned functions. The suction and irrigation elements may comprise one or more fluid paths configured to deliver fluid to or evacuate fluid from a surgical field. In this way, a user, such as a clinician or surgeon, may rely on a single surgical instrument to perform these tasks typical in surgery while having an extra hand available and so as to not need to divert his or her concentration away from the surgical site in order to access multiple devices. Further, the timing for performing each of the functions may be made quicker, due to not needing to switch using multiple devices.

The stylus allows a practitioner to maintain focus on the treatment location while adjusting placement and force. This is because a light signal is emitted in the vicinity of the distal end of the stylus, proximate the treatment location on the patient. Alternatively, an audible or a tactile signal is employed for feedback. As a safety feature, the stylus is provided with means to allow it to collapse at forces above the acceptable limit.

  • Patent number: 9492320
    Abstract: Shunt devices and a method for continuously decompressing elevated intraocular pressure in eyes affected by glaucoma by diverting excess aqueous humor from the anterior chamber of the eye into Schlemm's canal where post-operative patency can be maintained with an indwelling shunt device which surgically connects the canal with the anterior chamber. The shunt devices provide uni- or bi-directional flow of aqueous humor into Schlemm's canal.

  • Patent number: 9433725
    Abstract: A hand piece having an irrigation portion and an aspiration portion that are releasably coupled is disclosed. In an assembled configuration, the irrigation portion and the aspiration portion are coupled such that the hand piece may be manipulable by a user as a single unit. In a separated configuration, the irrigation portion and the aspiration portion may be utilized separate from each other. The irrigation portion and the aspiration portion may be freely moved between the assembled configuration and the separated configuration.

  • Patent number: 9387041
    Abstract: An apparatus and method for laser-assisted machining (LAM) of bone without raising the temperature of the surrounding bone is discussed. The method of LAM of bone involves determining a target bone needing to be machined an then scanning a high power density laser beam along the bone at a machining rate that produces low-heat affected zones (HAZ) on the target bone. The process and apparatus is advantageous over conventional technologies because it provides a chemically clean, coherent, and monochromatic beam to the region to be machined.

  • Patent number: 9351871
    Abstract: Embodiments described herein provide ophthalmic surgical instruments. One embodiment provides an instrument including an infusion sleeve, aspiration tube, and infusion/aspiration tip. The sleeve can include a body defining an infusion channel. The tube can be in the infusion channel and define an aspiration channel. The tip can conform to the distal end of the tube. The tip can seal a gap between the sleeve and tube and can include a flange with a profile (e.g., a tapered portion) corresponding to the profile of the sleeve. The sleeve and tip can be keyed such that the sleeve directs fluid in one direction and the tip draws fluid perpendicularly from that direction. The tip's aspiration channel can extend distally beyond its aspiration port. The tip can extend to a point adjacent to an infusion port of the sleeve. A disposable component (including an aspiration tube and infusion/aspiration tip) for use with instruments is provided.

  • Patent number: 9144517
    Abstract: A control device for an ophthalmic surgical system includes a flow determination device for determining an actual value of fluid flow in an aspiration line. The aspiration line is coupled to a handpiece for phacoemulsification of an eye lens and an occlusion determination device determines whether there is an occlusion because of a particle of the eye lens at a suction opening of the aspiration line. An evaluation unit establishes a hardness of the particle in dependence on the determined actual value of the fluid flow in the aspiration line should the occlusion determination device have determined that an occlusion is present, and, dependent on the hardness, determines a first value of ultrasound energy, which can be supplied to the handpiece by an energy source. A control unit actuates the energy source, during the occlusion, so that it outputs the determined first value of the ultrasound energy.
