摘要:
The invention provides biodegradable implants sized for implantation in an ocular region and methods for treating medical conditions of the eye. The implants are formed from a mixture of hydrophilic end and hydrophobic end PLGA, and deliver active agents into an ocular region without a high burst release.

摘要:
Described herein are formulations and methods for treating, inhibiting, preventing, delaying onset, or causing regression of a disease or condition relating to vascular permeability.
摘要:
Described herein are liquid rapamycin formulations. Described herein are methods of treating or preventing diseases or conditions, such as choroidal neovascularization, wet AMD and dry AMD, and preventing transition of dry AMD to wet AMD, using the liquid rapamycin formulations described herein.
摘要:
Implants and microimplants are provided comprising homogeneous mixtures of active ingredient and bioerodible polymer, including microimplants having diameters of 0.019 inches or less and which can be delivered to the eye using self-sealing methods. Methods of manufacturing the implants and microimplants are provided that yield batches of highly uniform implants and microimplants within very narrow tolerance ranges.
摘要:
Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are liquid formulations which deliver a variety of therapeutic agents, including but not limited to rapamycin, to a subject for an extended period of time; liquid formulations which form a non-dispersed mass when placed in an aqueous medium of a subject; non-dispersed mass-forming liquid formulations which form a gel or gel-like substance in an aqueous medium; liquid formulations, comprising a therapeutic agent and a plurality of polymers; and methods for delivering therapeutic agents to a subject for an extended period of time using the liquid formulations. The liquid formulation may be placed in an aqueous medium of a subject, including but not limited to via intraocular or periocular administration, or placement proximate to a site of a disease or condition to be treated in a subject. A method may be used to administer rapamycin to treat or prevent angiogenesis, choroidal neovascularization, or age-related macular degeneration, or wet age-related macular degeneration in a subject. The liquid formulations may comprise rapamycin or other therapeutic agents.
摘要:
Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are solid drug delivery systems and methods for providing extended delivery of therapeutic agents to such tissues. A solid drug delivery system may be placed in a subject, including but not limited to placement between the sclera and the conjunctiva or transscleral placement. Described methods may be used to administer rapamycin to treat or prevent angiogenesis, choroidal neovascularization, age-related macular degeneration, or wet age-related macular degeneration in a subject. The solid drug delivery devices may comprise rapamycin or other therapeutic agents. Also described are methods of treating ocular diseases or disorders by administering an antiproliferative agent, including but not limited to rapamycin, proximal to an ocular device.
摘要:
Diseases and conditions associated with tissues of the body, including tissues in the eye, can be effectively treated by administering therapeutic agents to those tissues. Described herein are self-emulsifying formulations and methods for delivering therapeutic agents to such tissues. A self-emulsifying formulation may be delivered to an aqueous medium of a subject, including but not limited to the vitreous. A method may, for instance, be used to administer rapamycin or related compounds to treat or prevent choroidal neovascularization associated with age-related macular degeneration, or to treat dry AMD. A self-emulsifying formulation may also be administered systemically, such as orally, to treat transplant rejection in a subject. A self-emulsifying formulation may comprise rapamycin, related compounds, or other therapeutic agents.
摘要:
An apparatus and methods for delivering ocular implants or microimplants. The apparatus is ergonomically designed for ease of use, and a simple manual depression of an actuator produces proportional movement of a linkage causing the implant or microimplant to be ejected through a cannula disposed at the desired location in the eye. Small gauge cannulas are provided for self-sealing methods of delivery.
摘要:
Particles emitted by radio-isotopic by-products of nuclear fission are used as a power source at the cathode of a magnetron system. Particles include high energy electrons having a large associated EMF. In the system a radial electrical vector E, between the cathode and anode, interacts with an axial magnetic vector B vector to produce an E×B force that rotates the particles about the system axis. These emissions are within a set range of velocities. The angular velocity and geometry of a rotating field, known as a space charge wheel (SCW), may be modulated by an external RF inputs to cavities of an anode block and the use of concentric biasing grids between the cathode and anode block. The SCW induces LC values into cavities of the anode, exciting them and producing electrons resonance which may be used to generate power.
