Publication number: 20070106199Abstract: 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.Type: ApplicationFiled: October 31, 2005Publication date: May 10, 2007Inventors: Daniel Krivoy, Mohsen Shahinpoor, David Soltanpour

Patent number: 7090696Abstract: 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.Type: GrantFiled: January 16, 2003Date of Patent: August 15, 2006Assignee: Environmental Robots, Inc.Inventors: Mohsen Shahinpoor, Parsa Shahinpoor, David Soltanpour

Patent number: 7060094Abstract: 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.Type: GrantFiled: January 12, 2001Date of Patent: June 13, 2006Assignee: Ophthalmotronics, Inc.Inventors: Mohsen Shahinpoor, David Soltanpour

Patent number: 6682500Abstract: 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.Type: GrantFiled: April 25, 2001Date of Patent: January 27, 2004Inventors: David Soltanpour, Mohsen Shahinpoor

Patent number: 6511508Abstract: 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.Type: GrantFiled: August 4, 2000Date of Patent: January 28, 2003Assignee: Environmental Robots, Inc.Inventors: Mohsen Shahinpoor, Parsa Shahinpoor, David Soltanpour
