The cannula assembly also comprises a hub couplable to the head and having a housing with an inner wall. The inner wall comprises an undercut, and one or more distal ends of the corresponding one or more wings are configured to fit into the undercut and couple the hub to the head upon insertion of the head into the hub.

Abstract: A trocar-cannula insertion tool for ophthalmic procedures may include a cap with a body having a proximal end and a distal end opposite the proximal end. A marking element extends in a distal direction from the distal end of the body and includes at least one marking tip for forming one or more indentations on a patient's eye during an ophthalmic procedure. A manipulation element extends from the body in a direction different from the marking element and includes at least one manipulation tip for gripping a tissue of the patient's eye during the ophthalmic procedure. The cap may further include at least one window for exposing a photoluminescent cannula of the trocar-cannula insertion tool to light, enabling the cannula to absorb photons prior to insertion thereof.

Abstract: Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure. The infusion cannula includes a tubular body with a tubular inlet located at a proximal end of the tubular body and a tubular outlet located at a distal end of the tubular body. The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.

Abstract: A platform configured to secure a service loop of tubing from a fixed position surgical device. The platform allows for avoidance of taping and re-taping of service loops. Additionally, the platform provides stability to the surgical device so as to avoid unintentional changing of position or orientation of the device. This is of particular benefit for an infusion port during eye surgery and other similar devices where orientation of the installed device aids device performance.

Abstract: Embodiments disclosed herein provide devices, systems, and methods for instrument exchanges during ophthalmic surgery. More particularly, the present disclosure relates to valved cannula assemblies and methods of use thereof. A valved cannula assembly includes a cannula having a head at a proximal end of the cannula and a hollow rod extending from the head to a distal end of the cannula. The valved cannula assembly includes a valved hub coupled to the head and including a septum having two or more curved flaps configured to provide an opening for an instrument.

Abstract: In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.
