METHOD FOR THE IMPROVEMENT OF MESH IMPLANT BIOCOMPATIBILITY
The present invention provides a method of fixating a mesh implant to a tissue of a subject comprising attaching said mesh implant to said tissue, covering said mesh implant by an antiadhesive barrier, wherein said antiadhesive barrier is attached to said mesh implant by a biocompatible adhesive.
Degradable Iron-Base Alloy Support
A degradable iron-based alloy stem comprises an iron-based alloy substrate and a degradable polymer in contact with the surface of the substrate. The weight-average molecular weight of the degradable polymer is in the range of [1, 100]*10.sup.4, and the polydispersity index of the degradable polymer is in the range of (1.0. 50]. The degradable polymer is selected from a degradable polyamino acid that can generate an acidic amino acid after degradation; or a mixture of the degradable polyamino acid and a degradable polyester, or a copolymer of monomers of the two; or a mixture of the degradable polyamino acid and a degradable polymer that does not generate acidic products after degradation, or a copolymer of the monomers of the two; or a mixture of the degradable polyamino acid, the degradable polyester and the degradable polymer that does not generate acidic products after degradation, or a copolymer of monomers of the three, or a mixture of a copolymer of monomers of any two of the three with the remaining one.
Thermoplastic sheet, a radiation mask of thermoplastic sheet and method for providing said sheet and said mask
The present invention relates to a thermoplastic composition suitable for manufacturing a thermoplastic sheet for producing a medical cast, such as a radiation mask. The composition has a polymeric component comprising a mixture of a styrene acrylonitrile copolymer and polycaprolactone, optionally together with a cross-linker and/or a filler, wherein the polymeric component comprises, 20 to 40 weight % of a styrene acrylonitrile copolymer and 80 to 60 weight % of a polycaprolactone, expressed in weight % of the polymeric component, wherein the thermoplastic composition has a glass transition temperature of 35° C.-80° C. The invention further relates to a thermoplastic sheet and to a medical cast, in particular a radiation mask, obtainable from said composition. In a final aspect, the invention relates to a method for producing said sheet and said radiation mask.
