Compositions are described comprising a polymer; a non-physiological pH solution; and a visualization agent; wherein the polymer is soluble in the non-physiological pH solution and insoluble at a physiological pH. Methods of forming the solutions and polymers are disclosed as well as methods of therapeutic use.

Polymeric treatment compositions

Polymeric compositions are described comprising a biocompatible polymer including a biodegradable linkage to a visualization agent and a non-physiological solution; wherein the biocompatible polymer is soluble in the non-physiological solution and insoluble in a physiological solution. Methods of forming the solutions and polymers are disclosed as well as methods of therapeutic use.

Devices for the occlusion of body cavities, such as the embolization of vascular aneurysms and the like, and methods for making and using such devices are described.

Embolization device constructed from expansile polymer

Devices for the occlusion of body cavities, such as the embolization of vascular aneurysms and the like, and methods for making and using such devices. The devices may be comprised of novel expansile materials, novel infrastructure design, or both. The devices provided are very flexible and enable deployment with reduced or no damage to bodily tissues, conduits, cavities, etceteras.

Polymers are described herein comprising: a reaction product of a prepolymer solution including at least one macromer and at least one visualization agent; and an active agent electrostatically bound to the polymer filament or chemically bound to the at least one monomer; wherein the polymer filament does not include metallic support members.

Polymers including active agents

Polymeric compositions are described comprising a biocompatible polymer including a biodegradable linkage to a visualization agent and a non-physiological pH solution; wherein the biocompatible polymer is soluble in the non-physiological pH solution and insoluble at a physiological pH. Methods of forming the solutions and polymers are disclosed as well as methods of therapeutic use.

Described herein are apparatus, compositions, systems and associated methods to occlude structures and malformations of the vasculature with radiopaque hydrogel filaments with delayed controlled rates of expansion. Further described is a device for implantation in an animal comprising a difunctional, low molecular weight ethylenically unsaturated shapeable macromer; an ethylenically unsaturated monomer; and a radiopaque element, wherein said device contains no support members. Methods of forming such devices are also disclosed.

Embolic devices

Polymer filaments including pharmaceutical agents and delivering same

Described are devices for implantation comprising a hydrogel filament wherein the hydrogel filament includes a low molecular weight ethylenically unsaturated macromer, an ethylenically unsaturated monomer, and a visualization agent. Methods of making and using these devices are also described.
