  • Tissue treatment
    Patent number: 7611542
    Abstract: A method of treating tissue includes placing substantially spherical polymer particles in the tissue. The particles include an interior region having relatively large pores and a first region substantially surrounding the interior having fewer relatively large pores than the interior region.
    Type: Grant

  • COMPRESSIBLE PARTICLES
    Publication number: 20090169641
    Abstract: Disclosed herein are methods that include providing a first particle having pores, the first particle having a first compression test value, and partially cross-linking the first particle to form a second particle having pores, the second particle having a second compression test value that is larger than the first compression test value by 25% or more, where a maximum dimension of the first particle is 5,000 microns or less, and a maximum dimension of the second particle is 5,000 microns or less.

  • Blood-tight implantable textile material and method of making
    Patent number: 7329531
    Abstract: An unmodified textile material is combined with a mixture including a non-colloidal polysaccharide slurry to form a blood-tight implantable textile material. A substantially porous unmodified textile material is impregnated with a biocompatible, bioresorbable slurry to make an implantable textile material, preferably in the form of a vascular graft. Sodium alginate is a preferred polysaccharide to use in the mixture, which serves as a viable alterative to collagen impregnation and coatings of vascular grafts.
