An assembled blank may include a blank tip attached to a blank base, e.g., the blank tip may be welded to the blank base. The blank tip may be manufactured by modifying flat stock, e.g., tiers of blank tips may be manufactured by modifying tiers of flat stock. The blank tip may comprise a first forceps jaw, a second forceps jaw, and a blank tip aperture. The assembled blank may be disposed within a hypodermic tube and an actuation structure of a microsurgical instrument.

A device for reducing the incidence of surgical debris migration within a mammalian eye comprising an anterior portion, the anterior portion with an anterior inner surface and an opposing anterior outer surface, the anterior inner surface and the anterior outer surface terminating at an anterior edge that defines an open anterior end; and a posterior portion, with a posterior inner surface and an opposing posterior outer surface, the posterior inner surface and the posterior outer surface terminating at a posterior edge, the posterior edge defining an open posterior end; and a waist connecting the anterior portion and the posterior portion, the waist comprising a waist inner surface and an opposing waist outer surface; and an aperture extending from the open anterior end, through the waist, and to the open posterior end, the aperture bounded by the anterior inner surface, the waist inner surface, and the posterior inner surface.

An instrument for removing debris from an eye during the treatment of an ocular disorder has a swab and a rigid member. The swab includes a tip portion sized to provide access to the debris on an eyelid of the eye. The rigid member has a distal end portion affixed to the swab and a proximal end portion with a cross-sectional member profile. The cross-sectional member profile is non-circular and has a first groove. The first groove extends longitudinally along the proximal end portion for cooperating with a chuck such that rotation of the proximal end portion within the chuck is inhibited.

The invention relates generally to the field of medical devices and, more specifically, to a handheld device that stimulates the meibomian gland of the eyelid mechanically, and specifically stimulates the meibomian glands of the eyelid to treat Meibomian gland dysfunction, also known as Dry eye and chronic marginal eyelid inflammation.

Peristaltic pump assemblies that include two-part fluid chambers are provided. In some embodiments, a pump assembly can include a roller assembly and a two-part fluid chamber comprising a hard outer portion and a flexible membrane coupled to the hard outer portion. The hard outer portion includes a concave or bell-shaped curved surface and a flexible membrane attached to the hard outer portion and extending over the curved surface of the hard outer portion. The bell-shaped groove and the flexible membrane define the fluid channel, and a roller coupled to the fluid chamber and configured to deform the flexible membrane against the bell-shaped groove on the inner surface of the hard outer portion to collapse the fluid channel. The two-part construction of the fluid chamber can decrease the amount of stress experienced by the flexible membrane, thereby increasing the longevity of the fluid chamber.

Methods, systems, and compositions for maintaining functioning drainage blebs to reduce intraocular pressure (IOP) of an eye being treated for glaucoma. The methods, systems, and compositions feature the combination of a minimally invasive glaucoma surgery (MIGS) implant or procedure and the application of beta radiation to the bleb. The beta radiation can function to inhibit or reduce the inflammation and/or fibrogenesis that typically occurs after insertion of a MIGS implant and leads to bleb failure. By reducing inflammation and/or fibrogenesis, the MIGS implant and the blebs can remain functioning appropriately.

Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

An ophthalmic tool and methods are shown. Examples of ophthalmic tools include cannula removal portions that include one or more grippers. In use the grippers, a mandrel, and a tool base provide a surgeon with a level of control that facilitates removal of a cannula. Other examples include a wound visualization tool that may be in combination with a cannula remover.

Various membrane delamination devices for removing proliferative membranes from underling tissues are disclosed herein. In some implementations, the delamination device may include a first shearing part and a second shearing part. One of the first shearing part and the second shearing part may be moveable relative to the other of the first shearing part and the second shearing part. One or more of the shearing parts may include a plurality of teeth formed at a leading edge thereof. A shearing action produced by operation of the shearing parts may be used to sever fibers joining proliferative membranes from an underlying tissue.

The present disclosure provides medical devices for creating a channel in a biological soft tissue. The devices comprise an integral rotatable tool formed by an elongated distal member and a proximal shaft, the elongated member having a distal end portion and a proximal end portion, the distal end portion comprising a tissue piercing tip of a pyramid-like shape, and the proximal end portion comprising an elongated prism-like portion having at least three surfaces and respective prism edges, with at least one of the prism edges between the surfaces being configured as a tissue cutting blade, and the proximal shaft interfacing and extending from the prism-like portion and having a cross section larger than a cross section of the prism-like portion at the interface. In some embodiments, the device comprises an intermediate portion extending between the distal end portion and the proximal end portion and having a frustum shape, thereby forming a smooth transition between a base portion of the tissue piercing tip and the proximal end portion.
