  • Publication number: 20050143817
    Abstract: Implants are used in combination with an anti-scarring agent in order to inhibit scarring that may otherwise occur when the implant is placed within an animal. The agent may be any suitable anti-scarring agent, e.g., a cell cycle inhibitor, and may be used in conjunction with a second pharmaceutical agent, e.g., an antibiotic. Suitable implants include intravascular implants, a vascular graft or wrap implant, an implant for hemodialysis access, an implant that provides an anastomotic connection, ventricular assist implant, a prosthetic heart valve implant, an inferior vena cava filter implant, a peritoneal dialysis catheter implant, a central nervous system shunt, an intraocular lens, an implant for glaucoma drainage, a penile implant, an endotracheal tube, a tracheostomy tube, a gastrointestinal device, and a spinal implant.

  • Publication number: 20050142163
    Abstract: Implants are used in combination with a fibrosis-inducing agent in order to induce fibrosis that may otherwise not occur when the implant is placed within an animal or increase fibrosis between the implant and the host tissue.

  • Publication number: 20040225077
    Abstract: Compositions are disclosed that afford drug delivery from two-part polymer compositions that rapidly form covalent linkages when mixed together. Such compositions are particularly well suited for use in a variety of tissue related applications when rapid adhesion to the tissue and gel formation is desired along with drug delivery. For example, the compositions are useful as tissue sealants, in promoting hemostasis, in effecting tissue adhesion, in providing tissue augmentation, and in the prevention of surgical adhesions.

  • Publication number: 20040219214
    Abstract: A composition comprising a synthetic polymer, optionally in the presence of a drug, where the polymer comprises multiple activated groups. The multiple activated groups are reactive with functionality present on animal tissue, so that upon administration of the polymer to the tissue, the polymer binds to the tissue. Alternatively, the multiple activated groups are reactive with functionality present on a non-living surface, where the polymer binds to this surface to, e.g., increase the lubricity of the surface. When drug is present in the composition, the drug is then delivered to the site of polymer attachment.

  • Publication number: 20040197408
    Abstract: Formulations are formed of a diblock copolymer (X—Y) having a hydrophilic block X comprising residues of monomer x, and a hydrophobic block Y comprising residues of monomer y; an additive selected from an amino acid and an oligopeptide. Upon admixture with water, the formulations form drug delivery vehicles, preferably in micellar form. The inclusion of amino acid and/or oligopeptide provides for the formation of micelles at an enhanced rate, and/or provides the formation of micelles having an enhanced ability to incorporate drug(s), and/or provides the formation of micelles having advantageous physical characteristics.

  • Publication number: 20040199241
    Abstract: Silk-containing stent grafts are provided comprising an endoluminal stent and a graft, wherein the silk is induces the in vivo adhesion of the stent graft to vessel walls, or, otherwise induces or accelerates an in vivo fibrotic reaction causing said stent graft to adhere to vessel wall. Also provided are methods for making and using such stent grafts.
