An instrument to facilitate hands-free illumination of an eye for a surgical procedure. The instrument includes an optical end of unique architecture and surfacing such that the instrument may be left immobile while sufficiently illuminating an eye interior with greater than 100° of wide beam spread angle provided. Further, the grind surfacing provided to the end cone of the optical end provides enhanced light distribution.

Methods and apparatus for wide angle chandelier illuminator

Multi-spot laser probe handpiece

In some embodiments, a vitrectomy probe may include an inner cutting tube reciprocating in an outer tube. The outer tube includes a side port and the inner tube includes a distal cutting port, and, in some embodiments, an additional side port. In some embodiments, the inner tube may also include a flat upper edge that cuts across the outer tube side port. In some embodiments, a diaphragm drives the inner tube and may have an open-stroke side with a lower hardness material than a closed-stroke side. In some embodiments, an aspiration tube coupled to the vitrectomy probe may include a first aspiration tubing and a second aspiration tubing with a lower hardness than the first aspiration tubing. In some embodiments, the vitrectomy probe may be coupled to pneumatic tubing that is stepped or tapered.

Vitrectomy probe

Embodiments disclosed herein provide devices, systems, and methods for illuminating inside an eye globe. More particularly, the present disclosure relates to ergonomic chandelier illumination systems for illumination of a surgical site during ophthalmic surgery, the chandelier illumination systems having improved flexibility, profile, and light coupling efficiency. In certain embodiments, a malleable chandelier illumination probe, which is bendable by a surgeon to any desired angle, is disclosed. In certain other embodiments, a preformed chandelier illumination probe, which is preset to a desired angle using a heating method, is disclosed. In certain other embodiments, a method for belling and binding two optical fibers to create a dual chandelier output with improved light coupling efficiency, which is capable of being used with a single connector, is disclosed.

Ergonomic chandelier endo-illumination probe

Certain aspects of the present disclosure provide a probe comprising a tube, wherein one or more optical fibers extend at least partially through the tube for transmitting at least one of a laser light and an illumination light from a light source to a target location. A distal end of the tube comprises a flat-walled morphology, and a protective window with a round edge is press-fit to the distal end. The flat-walled morphology of the distal end of the tube has a reduced diametric interference sensitivity, thus allowing a wider range of tolerances between the window and the tube walls for effective press-fitting.

Ophthalmic probe assembly with flat wall tube

The present disclosure relates to a laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to the lens.

Multi-spot laser probe with multiple single-core fibers

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores, a cladding surrounding the plurality of cores, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding, and a coating surrounding the cladding, a distal end free of the coating and having a reduced diameter. The MCF also comprise an annular gap formed between the distal end of the MCF and the inner surface of the cannula, wherein the concentricity of the distal end of the MCF with the inner passage of the cannula is maintained.

Multi-core fiber for a multi-spot laser probe

A method of manufacturing an articulating ophthalmic surgical probe includes providing a cannula having an outer diameter of 20 Ga or less and a slotted tip, permanently attaching a pull wire to the slotted tip, permanently attaching a metal anchor to a distal end of the pull wire, positioning a weld pin within a handle assembly that is sized to fit within a single hand, and welding the metal anchor to the weld pin within the handle assembly.

Manufacturing an articulating ophthalmic surgical probe

Embodiments of endo-illuminators and related methods are disclosed. One embodiment of an illuminator can comprise a cannula defining a passage, an optical element disposed at an end of the cannula, and an optical fiber running through the passage with the distal end of the optical fiber in contact with the optical element. The optical fiber includes at least a heat preconditioned distal portion that terminates in the distal end that is in contact with the optical element. One embodiment of a method can comprise inserting an optical fiber through a proximal portion of a cannula and optical element assembly until the distal end of the optical fiber contacts the optical element, heating a distal portion of the optical fiber to between a softening temperature and a melting temperature for a period of time to cause the distal portion to axially shrink and moving the optical element so that the optical element is in contact with the distal end of the optical fiber when the distal portion of the optical fiber has axially shrunk. Moving the optical element so that the optical element is in contact with the distal end of the optical fiber when the distal portion of the optical fiber has axially shrunk can comprise applying a force to the cannula and optical element assembly to maintain the optical element in continuous contact with the distal end of the optical fiber while the optical fiber axially shrinks.

Preconditioned illuminator system and method

Embodiments of endo-illuminators and related methods are disclosed. One embodiment of an illuminator can comprise a cannula defining a passage, an optical element disposed at an end of the cannula, and an optical fiber running through the passage with the distal end of the optical fiber in contact with the optical element. The optical fiber includes at least a heat preconditioned distal portion that terminates in the distal end that is in contact with the optical element.

Devices for affixing sutures, grafts and tissues to bone, and soft tissue such as periosteum. Such devices are designed to be deployed and selectively positioned at a target site and remain seated thereat. The devices are further provided with attachment structures for securing sutures, grafts, synthetic materials or tissues thereto which facilitates the ability of such devices to remain more firmly in position.

Systems for securing sutures, grafts and soft tissue to bone and periosteum

Devices for affixing sutures, grafts and tissues to bone, and soft tissue such as periosteum. In a first embodiment, the invention comprises a piton member implantable within bone having a post or eyelet formed thereon to which the suture or tissue may be attached. The piton member is designed to become more firmly secured within the bone when pressure is applied to a first axis pushing the piton member into the bone, but may be easily removed when such force is applied in a generally opposed direction. In a second embodiment, the invention comprises affixation devices that are designed to detachably ensnare with periosteum. Such devices are provided with attachment structures, such as one post, eyelet or other means for securing sutures, grafts, synthetic materials or tissues.

A portable, ambulatory infusion pump for use with standard pre-filled infusion medicament containers is powered by a miniature compressed gas cylinder coupled to a mechanical pressure regulator which supplies regulated gas at a substantially constant pressure to an inflatable bladder. The bladder is positioned between a substantially rigid pressure surface and a moveable pressure transfer plate and pushes against the transfer plate when inflated. A pre-filled medicament container is positioned over the pressure transfer plate and is squeezed between the transfer plate and the pump housing cover as the plate is displaced in response to inflation of the flexible bladder. A safety interlock assembly is connected between the pressure regulator and the inflatable bladder and prevents inflation of the bladder unless the housing cover is completely closed. Upon inadvertent opening of the pump, the internal pressurization system is vented to atmosphere.
