Abstract
An improved non-toxic soft tissue filler is provided. The soft non-toxic tissue filler consists of textured surfaced spherically shaped solid particles of a size range of between about 32 and 90 microns (depending on the concentration that is desired) that are suspended evenly in a gel as a carrier. The solid particles are preferably a non-ceramic cured polymer such as polymethylmethacrylate (PMMA). The gel is a combination of a cellulose polysaccharide such as carboxymethylcellulose (CMC) and an alcohol such as polyvinyl alcohol (PVA) dissolved in water or some other solvent. The filler is used by injection in order to augment a patient's soft tissue as well as to correct soft tissue defects.
Claims19
A tissue filler product comprising between about 10 and 30 weight percent of histocompatible solid particles of a non-ceramic curable polymer and between about 90 and 70 weight percent of degradable gel as a carrier in which said particles are suspended, said gel comprising a polysaccharide as an emulsifier in an amount between about 0.5 and 5.0 weight percent, a dissolvable alcohol in an amount between about 0.5 and 10.0 weight percent, and the balance being water.
A tissue filler product comprising between about 1 and 30 weight percent of polymethyl methacrylate particles and between about 90 and 70 weight percent of a degradable gel as a carrier in which said particles are suspended, said gel comprising carboxymethyl cellulose as an emulsifier in an amount between about 2.0 and 2.5 weight percent, polyvinyl chloride in an amount between about 4.0 and 4.5 weight percent, and the balance being water.
A tissue filler system comprising a tissue filler made from histocompatible solid particles of methacrylate polymers suspended in a gel as a carrier;
- the gel comprising a cellulose polysaccharide as an emulsifier, a dissolvable alcohol, and the balance being water;
- the tissue filler being in three distinct concentrations with the first concentration comprising said solid particles with a diameter of between about 32 and 52 microns, the second concentration comprising said solid particles with a diameter between about 53 and 74 microns, and the third concentration comprising said solid particles with a diameter of between about 75 and 90 microns.
