Abstract
An in situ forming foam for medical applications and a method for making same is described, the method comprising the steps of: preparing a first component, Composition A, comprising an acidic solution of a polycationic polymer selected from the group comprising polymeric amines and polysaccharides; preparing a second component, Composition B, selected from the group comprising a metal carbonate, a metal bicarbonate or a mixture of a metal carbonate and a metal bicarbonate; maintaining said first and second components separately prior to mixing; and mixing said first and second components at an intended site of application. The foam is a mechanically robust but flexible and resilient material wherein the degree and nature of the porosity may be controlled.
Claims51
A method of making a foam material, the method comprising the steps of preparing two separate constituents designated as Composition A and Composition B, wherein
- Composition A comprises an acidic solution of a polycationic polymer selected from the group consisting of polymeric amines and polysaccharides and
- Composition B comprises a component selected from the group consisting of metal carbonates, metal bicarbonates, and mixtures of metal carbonates and bicarbonates,
- said Compositions A and B being mixed together and upon reaction therebetween forms said foam material.
