  • Patent number: 9457090
    Abstract: Bioactive hydroforming luminal liner compositions are formed of an absorbable crystalline amphiphilic polyether-ester-urethane dissolved in a liquid derivative of a polyether glycol that undergoes transformation into a tissue-adhering, resilient interior cover or liner for the controlled release of its bioactive payload at clinically compromised conduits in humans as in the case of bacteria- and yeast-infected vaginal canals, esophagi, and arteries following angioplasty.
    Type: Grant
    Filed: April 7, 2014
    Date of Patent: October 4, 2016
    Assignee: Poly-Med, Inc.
    Inventors: Shalaby W. Shalaby, David Ingram, Georgios Hilas, Sheila Nagatomi
  • Patent number: 9006278
    Abstract: Controlled release systems release at least one pluribioactive antifungal drug exhibiting at least one additional bioactivity from the group consisting of spermiostatic, antineoplastic, antibacterial, antirestenotic and antiviral activities. The drug release system is designed for use as a spermiostatic contraceptive, intravaginal ringed-mesh which may also exhibit antiviral activity, an in situ-forming implant for treating different forms of cancer and topical film for treating or preventing bacterial and fungal infections.

  • Patent number: 8076388
    Abstract: Self-setting, absorbable bioactive polycyanoacrylate-based composites include at least one inorganic phosphate salt or a combination of at least one inorganic phosphate salt and calcium silicate in a cyanoacrylate matrix. The composites can be reinforced with single- or multicomponent absorbable, warp-knitted mesh, thus producing a broad range of absorbable, bioactive biomaterials suitable for use not only as preferred absorbable alternatives to the commercial non-absorbable polymethyl methacrylate bone cements, but also for repairing or replacing cranial and maxillofacial bone defects and other complex defects through guided bone regeneration.
