Abstract
The invention is a resorbable, viscous to solid wax for the mechanical staunching of blood on hard body tissue, particularly bones, based on oligomers of glycolic acid and/or lactic acid and derivatives thereof with monofunctional and/or polyfunctional alcohols and/or corresponding carboxylic acids. The new waxes are characterized by containing body-compatible salts of organic and/or inorganic acids which are formed by corresponding reaction of any free carboxyl groups present in the oligomer wax and/or are incorporated in the wax in homogeneous distribution as added salts.
Claims24
A resorbable, body compatible viscous to solid wax for the mechanical staunching of blood on hard body tissue, comprising:
- at least one oligomer composition formed by the esterification of at least one acid selected from the group consisting of glycolic acid and lactic acid or such oligomers chain-terminated with at least one composition selected from the group consisting of monohydroxyl alcohols, polyhydroxyl alcohols and the corresponding carboxylic acids;
- and at least one body-compatible salt of an organic or an inorganic acid homogeneously distributed in the wax, the at least one oligomer composition being neutralized with a body-compatible salt forming composition.
