  • Rigid annuloplasty device that becomes compliant after implantation
    Patent number: 6159240
    Abstract: A band-shaped annuloplasty device (e.g., C- or D-shaped ring) that is relatively rigid during handling and implantation and becomes relatively complaint after implantation. Preferably, the device includes a core material that softens after implantation.

  • Process for making biomedical devices utilizing thermoplastic hydrophilic gels
    Patent number: 5002792
    Abstract: A method for making biomedical devices employing thermoplastic hydrogels on an operant surface thereof is described. The method generally involves heating a thermoplastic hydrogel to a temperature in the range of 50.degree. C. to about 95.degree. C. to a fluid flowable state, dispensing the fluid hydrogel onto the biomedical device and cooling the hydrogel to a substantially solid state. Microwave heating is preferred.

  • Hydrophilic pressure sensitive biomedical adhesive composition
    Patent number: 4593053
    Abstract: Novel, hydrophilic, skin-compatible, pressure sensitive, solid, adhesive gel hydrogel composition comprising 25 to 50 weight percent polyvinyl pyrolidone (PVP) preferably having a molecular weight in the range of about 100,000 to 600,000, 2 to 5 weight percent polyvinyl alcohol (PVA) preferably having a molecular weight in the range of about 150,000 to 300,000, about 5 to about 40 weight percent humectant, about 3 to about 50 weight percent water, about 0 to about 50 weight percent of an ionic species. In a preferred aspect, the composition of the invention is utilized in an iontophoresis device to provide a hydrophilic gel matrix from which a drug is iontophoretically delivered.
