    Abstract: The present invention discloses a method and a device or tooth pod for regeneration of teeth. In some exemplary embodiments, a method of implanting a tooth pod comprises of providing a tooth pod, implanting the tooth pod into an insertion point, and sealing the insertion point. The tooth pod comprises a composition of vitamin E oil and penicillin. In some exemplary embodiments, the tooth pod comprises of a permeable membrane defined by an outer layer and an inner layer, and a cavity defined by the space enclosed within the inner layer. In some exemplary embodiments, the device is a spherical pod. The tooth pod is implanted into the gum line at approximately ½ the depth of a tooth, which provides space to growth of tooth upwards and downwards. The blood fills the hollow space of the tooth pod and forms nerve roots. Thereafter, a new adult tooth is formed.

  • Patent number: 8399013
    Abstract: This invention describes a partially absorbable, fiber-reinforced composite in the form of a ring, or a suture-like thread, with modified terminals for use as a controlled delivery system of at least one bioactive agent, wherein said composite comprising an absorbable fiber construct capable of providing time-dependent mechanical properties of a biostable elastomeric matrix containing an absorbable microparticulate ion-exchanger to modulate the release of the bioactive agent(s) for a desired period(s) of time at a specific biological site; this can be a vaginal canal, peritoneal cavity, scrotum, prostate gland, an ear loop or subcutaneous tissue. Such drug delivery systems can be used for the local administration of at least one bioactive agent, including those used as contraceptive, antimicrobial, anti-inflammatory and/or antiviral agents as well as for cancer treatment.

  • Patent number: 8399012
    Abstract: A biodegradable biodelivery device is disclosed. The biodelivery device is formed from a polymer comprising the reaction product of a polyol and a polyacid. When exposed to water, the polymer degrades through hydrolysis. Of particular advantage, the polymer can be formed so as to be elastic and flexible. In one embodiment, the polymer is formed into a vaginal insert. As the polymer degrades, the polymer releases acid to a vaginal environment for decreasing the pH of the environment.

  • Patent number: 8226972
    Abstract: Drug delivery compositions which are suitable for vaginal administration for the treatment of diseases and disorders in the urogenital tract are described. The compositions may be in the form of a tablet, liquid suspension or dispersion, dried powder, topical ointment, cream, foam, suppository, or aerosol. The drug delivery compositions are administered directly to the vagina and do not require the use of a solid device. This method of administration reduces the systematic levels of the drugs.
