    Abstract: A two phase method for reducing the formation of biofilm includes an evacuation of ambient air from a region about the surgical or treatment site, to extract airborne or aerosolized bacteria ejected from the site by the treatment. The extracted bacteria are prevented from settling back onto the cleansed tissue surface, thus at least reducing colonial bacteriological growth and concomitantly exuded biofilm material. A second phase involves the attachment of one or more ultrasonic transducers to the patient over or near a surgical treatment site after the surgery is terminated. Each applied ultrasonic transducer is used to vibrate the patient's tissues at the treatment site to disrupt biofilm formation.

Thanks to its multi-cell structural design, it favors its placement and reduces the risk of migration, extrusion, exposure and extraction. As it is an arrangement with structural holes, it provides a higher percentage of the volume for its vascularization; it also houses inside a Reticular Fibrovascular Core System, which has a structure based on multilevels equipped with micro-reticular tissue and an intra-level communication based on filaments; with the capacity to contain medicines and/or technology by presenting a dual-system of two screw-on pieces, being able to manufacture in different structural designs and biocompatible materials.

  • Patent number: 11607338
    Abstract: Devices, systems, and methods for performing an ophthalmic procedure in an eye are disclosed. The devices include a hand-held portion and a distal, elongate member coupled to the hand-held portion having a lumen operatively coupled to a vacuum source. A drive mechanism operatively coupled to the elongate member is configured to oscillate the elongate member. When in use, the device is configured to aspirate ocular material from the eye through the lumen. The drive mechanism retracts the elongate member with a retraction speed profile and advances the elongate member with an extension speed profile. The retraction speed profile is different from the extension speed profile.

  • Patent number: 11596547
    Abstract: Embodiments of the invention provide hydrodissection and/or PCO prevention or reduction in a patient undergoing eye surgery. In one embodiment, the invention is a surgical device for cutting and excising a portion of tissue, for example in performing a lens capsulotomy. A capsulotomy tip is inserted into an eye through an incision in the surface of the eye. The capsulotomy tip includes a suction cup to provide suction to the lens capsule. Then suction is applied via the suction cup to secure the capsulotomy tip to the eye. In some embodiments, after the capsulotomy tip is secured to the lens capsule, a cutting element of the capsulotomy tip is used to cut a tissue of the eye. Fluid is pushed through the capsulotomy tip and the capsulotomy tip is removed from the eye. Moreover, disclosed is an intraocular lens (IOL) to be used in conjunction with the surgical device.

  • Patent number: 11590026
    Abstract: A method of controlling an eye surgical laser is disclosed for the separation of a volume body with predefined posterior and anterior interfaces from a human/animal cornea. The method including controlling the laser with a control device, the laser being configured to emit pulsed laser pulses in a predefined pattern into the cornea. The posterior and anterior interfaces of the volume body are defined by the predefined pattern and are generated by an interaction of the individual laser pulses with the cornea through photodisruption. The control device controls the laser beam such that both interfaces are generated via a continuous, uninterrupted sequence of laser pulses. A treatment device is disclosed with at least one eye surgical laser for the separation of a predefined corneal volume with predefined interfaces of a human/animal eye by photodisruption and with at least one control device for the laser(s).

  • Patent number: 11540948
    Abstract: A vibrating tissue separator suitable for use in separating a lenticule established by a femtosecond laser during a smile procedure may include a surgical implement such as a blunt spatula mounted on a handle that carries a haptic actuator for applying vibratory motion to the surgical implement. A damping arrangement may be provided to isolate the surgeons hand from the vibrations which would otherwise be transmitted through the handle. The actuator may apply a linear vibration along the axis of the handle which applies a lifting and chopping motion to the tip of a surgical implement having a bend. The tip may be suitable to the tissue being separated. For example, for SMILE lenticule separation, a blunt or semi-sharp spatula, blunted wire or loop may be used. The direction of vibration at the tip may be changed by rotating the implement in a plane other than the plane of the bend or by rotating an actuator such as an LRA with respect to the handle.
