  • Patent number: 8454691
    Abstract: A surgical procedure is described for the restoration of eyelid function in individuals suffering from ptosis or upper eyelid droop syndrome that makes a patient unable to voluntarily fully raise an eyelid. The surgical procedure includes implantation and suturing of eye drop (pH) activated and actuated fibrous contractile and expansive artificial muscles such as pH active hydrogels of polyacrylonitrile (PAN) artificial muscles that are surgically implanted and sutured under the superior palpebral conjunctiva in a serpentine parallel configuration with respect to the tarsal (meibomian) glands of the upper eyelid and anchored to the tissues of superior fornix.

  • Publication number: 20120116505
    Abstract: The present invention includes an ophthalmic device and system of mounting for correcting hyperopia, myopia and presbyopia. The present invention includes a limbus ring mountable in an encircling relation to a central optic zone of a cornea on a limbus annulus surrounding the cornea. In the limbus ring defines a substantially annular toroid defining a first average diameter that is selectable and has a hydrophilic coating disposed thereon. The inner radius of the limbus ring is selectable such that, upon mounting on the limbus annulus, the limbus ring causes the limbus annulus to contract or expand thereby causing the curvature of the cornea and the eye length to increase or decrease. The mounting system of the present invention is adapted to receive a limbus ring and further adapted to selectively place the limbus ring on a limbus annulus.

  • Publication number: 20070106199
    Abstract: An implantable, miniature pump assembly having a flexible elastic bladder actuating assembly. The bladder, in the non-flexed state, has an elongated, substantially rectangular profile, with a predetermined internal volume or capacity. Influent and effluent conduits extend in opposite directions from respective end portions of the bladder. Each of the conduits include one way valves disposed therein to limit fluid flow to a single direction into and through the bladder. Contraction and expansion of the bladder by means of energy harvested from the dynamic environment in which it is implanted in response to ambient random dynamic motion creates alternating pressure and vacuum within the bladder, alternately drawing fluid into the bladder through the influent conduit, and forcing fluid from the bladder via the effluent conduit.

  • Patent number: 7090696
    Abstract: Correction of eye refractive errors like presbyopia, hyperopia, myopia, and astigmatism using either pre-tensioned or transcutaneously energized artificial muscle implants to change the axial length and anterior curvatures of the eye globe by bringing the retina/macula region to coincide with the focal point. The implants are scleral constrictor bands, segments or ribs for inducing accommodation of a few diopters, to correct refractive errors on demand or automatically. The implant comprises an active sphinctering band encircling the sclera, implanted under the conjunctiva and under the extraocular muscles to uniformly constrict the eye globe, to induce active temporary myopia (hyperopia) by increasing(decreasing) the length and curvature of the globe. Multiple and specially designed constrictor bands enable surgeons to correct astigmatism.

  • Publication number: 20060167422
    Abstract: Discussed is a method and apparatus of correcting retinal detachments by heat-shrinking a specially designed scleral band equipped with a snap-on custom-made buckle for scleral indentation over the retinal tear region. The heat shrink band is made from a heat shrink material such as a polymer or an alloy and is equipped with a custom-made buckle to perfectly fit the topological geometry of the retinal detachment region over the underlying choroid and the sclera, the conjunctiva and within the Tenon's space wherein the band is heat shrunk to create a perfect buckle over the retinal tear region to reattach the retina to the choroid and cause absorption of the subretinal fluid. Conventional, laser, microwave, Joule or radio-frequency (RF) heating means are also discussed.

  • Patent number: 7060094
    Abstract: Surgical correction of presbyopia and hyperopia by a circularly distributed assembly of mini-bridges implanted between the interior surfaces of the ciliary muscle and the exterior surface of the lens capsule, for augmenting the transmission of the contraction force of the ciliary muscle/zonule assembly to the lens capsule. The lens is symmetrically squeezed by mini-bridges acting in concert with the ciliary muscle thus changing the curvature of the lens. The mini-bridges are composite synthetic muscles comprising either passive biocompatible mini-bridges made with polymeric gels, silicone polymers or a composite, electromagnetically or mechanically deployable mini-bridges, inflatable balloons or synthetic muscles. The surgical procedure comprises using a ciliary muscle relaxant to stretch the lens/zonules/ciliary muscle assembly.

  • Patent number: 6682500
    Abstract: Implantable, pressure adjustable diaphragm pump systems which are scalable and are characterized by a common type of actuating mechanism. The pumps may be inductively and transcutaneously powered via adjacent, mutually inductive electromagnetic coils. Alternatively the pumps may be effectively “self” powered using a synthetic muscle attached to a local bending or twisting force. The pumps may be used in a range of applications from mechanical applications to medical applications such as intraocular pressure control for glaucoma patients, bodily fluid drainage control, and drug delivery systems. These pump systems each include a pumping chamber having an anterior end attached to an implantable influent conduit. In the case of an ocular pressure control device, the influent conduit is inserted into the anterior chamber of the eye.

  • Patent number: 6589198
    Abstract: Self-powered, bio- implantable, pressure adjustable mini-pump systems for medical applications including body fluid pressure control, drainage control, and drug delivery systems. The mini-pump systems include a primary mini-pump chamber having an anterior end attached to an implantable intake conduit. The device of the invention is further equipped with an adjustable variable flow valve or shunt in the form of a first cantilever slab, in combination with an anterior end one-way valve in the form of another cantilever slab. The posterior end of the mini-pump chamber is connected to a drainage conduit, via another one-way valve. Opposing diaphragm elements in the form of a pair of oscillatory flexing miniature ionic polymer metal composite IPPC artificial muscles, is used to vary the volume of the primary mini-pump chamber and thereby effect pumping action.

  • Patent number: 6511508
    Abstract: Surgical correction of human eye refractive errors such as presbyopia, hyperopia, myopia, and stigmatism by using transcutaneously inductively energized artificial muscle implants to either actively change the axial length and the anterior curvatures of the eye globe. This brings the retina/macula region to coincide with the focal point. The implants use transcutaneously inductively energized scleral constrictor bands equipped with composite artificial muscle structures. The implants can induce enough accommodation of a few diopters, to correct presbyopia, hyperopia, and myopia on demand. In the preferred embodiment, the implant comprises an active sphinctering smart band to encircle the sclera, preferably implanted under the conjunctiva and under the extraocular muscles to uniformly constrict the eye globe, similar to a scleral buckle band for surgical correction of retinal detachment, to induce active temporary myopia (hyperopia) by increasing (decreasing) the active length of the globe.

  • Publication number: 20020182162
    Abstract: A new topical drug for enhancing hair growth or diminishing hair loss or alopecia, which comprises a mixture of a nitric oxide (NO) donor such as nitrovasodilators like minoxidil (RogaineRTM), nitroglycerin, L-arginine, isosorbide dinitrate, or nitroprusside, and a cyclic guanosine 3′,5′-monophosphate (cGMP) specific phosphodiesterase type 5 (PDE5) inhibitor such as sildenafil citrate (ViagraRTM) in a dermatologically acceptable solution mix. In this manner there will be increased vascular circulation and blood circulation to the hair bulbs and follicles and the effect of the combined compounds is enhanced synergistically.
