OCULAR IMPLANT CONTAINING A TYROSINE KINASE INHIBITOR
The invention relates to a sustained release biodegradable ocular implant containing a tyrosine kinase inhibitor dispersed in a hydrogel for the treatment of a retinal disease for an extended period of time.
SIZE-EXCLUSIVE DOSE-CONTROLLABLE DRUG DELIVERY IMPLANT
An implant device includes a polymer tube including an enclosed inner space, and a mixture of a hydrogel and a plurality of nanoparticles within the enclosed inner space. Each of the plurality of nanoparticles includes a shell, payload within the shell, and one or more photothermal agents on a surface of the shell. A wall of the polymer tube includes one or more layers of nanoporous polymer sheets including a plurality of pores. The dimension of the nanoparticles is greater than the dimension of the pores, and the dimension of the payload is smaller than the dimension of the pores.
Miniature Fixed and Adjustable Flow Restrictor for the Body
A microfluidic flow restrictor that uses micron-sized beads to impede flow is described. The flow rate can be adjusted by adding or removing the beads using injection needles through self-sealing ports, one injection needle injecting or aspirating beads and another injection needle pushing or pulling fluid from outside of a bead trap within the flow restrictor. In alternative embodiments, the beads or other filler material can be trapped in a manifold bead trap such that they block a subset of fluid channels of the flow restrictor, allowing fluid to flow freely through the rest of the fluid channels. The flow restrictor can be integrated with a contact lens or implantable medical device for use in dispensing liquid therapeutic agents at flow rates of microliters per minute or moving body fluids at a controlled rate from one part of the body to another.
SURGICAL HANDPIECE WITH ROTATABLE CANNULA HEAD
A microsurgical instrument includes a cannula head rotationally coupled to a handpiece. A cannula head connector at a distal end of the handpiece rotationally couples to a handpiece connector at a proximal end of the cannula head. The cannula head connector and handpiece connector rotate coaxially about a longitudinal center axis passing through a cannula extending from the cannula head, providing an adjustable cannula angle between the cannula head and handpiece. The cannula head is securely retained to the handpiece without slippage changing the cannula angle, and the cannula angle is easily changed to a new value by deliberate rotation of the cannula head.
DEVICE AND SYSTEM FOR INJECTING BIOLOGICAL TISSUE
A device, kit, and method for aspirating graft tissue and delivering the graft tissue to a target delivery site. An injector comprises a cylinder and a plunger that is both linearly and rotatably advanceable and retractable within the cylinder. A kit comprises an injector, a cartridge, and a cartridge coupling element that connects the cartridge to the injector. The kit may also include a container that is configured to retain a cartridge and to facilitate connection between the injector and the cartridge. The container includes at least one fluid barrier that prevents spillage of storage solution from the container when the injector is at least partially inserted into the well of the container.
Methods, systems, and compositions for maintaining functioning drainage blebs associated with foreign bodies
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.
Amniotic or placental device for ophthalmic use as a dressing with refractory center section
A biodegradable lens-shaped patch useful for healing and treatment of ocular conditions is disclosed. The patch is formed from a biodegradable carrier which carries amniotic extract and/or placental extract. The lens-shaped patch may be shaped in the form of a conventional contact lens and it is applied to a corneal surface to enhance healing thereof. After a certain period of time, the patch dissolves on its own and it need not be removed from the eye by a clinician. In an embodiment, the patch includes a clear central section that may be refractory, and a biodegradable peripheral section.
HYDRO-CONTACT LENS
An eye treatment device includes the following: a goggle frame, having at least one cavity, configured to surround and be spaced from an eye; a corrective lens along a face of the goggle frame; and an inlet formed in an upper portion of the goggle frame, the inlet fluidly communicating the cavity to an external environment; further including: a sealing material along a perimeter of the goggle frame for forming a hermetical seal against skin around a socket of the eye, wherein the sealing material is a portion of a suction cup; and further including a tapered stopper for fluidly sealing the inlet, wherein the corrective lens is made from gas permeable material.
IMPLANTS WITH CONTROLLED DRUG DELIVERY FEATURES AND METHODS OF USING SAME
Disclosed herein are drug delivery devices and methods for the treatment of ocular disorders requiring targeted and controlled administration of a drug to an interior portion of the eye for reduction or prevention of symptoms of the disorder. The devices are capable of controlled release of one or more drugs and may also include structures which allow for treatment of increased intraocular pressure by permitting aqueous humor to flow out of the anterior chamber of the eye through the device.
APPARATUS AND METHODS FOR OCULAR INJECTION
An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.
