Particles, such as particles including a polymer including vinyl formal monomer units, and related compositions and methods, are disclosed.

Polymeric particles comprising vinyl formal, vinyl alcohol and vinyl acetate monomer units

Coil assemblies and related components and methods are disclosed. The coil assemblies can include two or more embolic coils having one or more different coil parameters.

Coil assemblies, components and methods

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.

Tissue treatment

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.
