Devices and processes (e.g., improved Plasticized Melt Flow processes (PMF)
or improved Phase Separation Polymer Concentration (PSPC), etc.) used to make resorbable
and non-resorbable structures for treating and/or healing of tissue defects are
disclosed. Among the advantages of using these improved processes are the preservation
of molecular weight and the broadening of the processing conditions for temperature
sensitive polymers and therapies This reduction in processing temperature, pressure
and time can help to preserve the molecular weight and/or integrity of the final
product or any additive incorporated therein. The present invention relates to
an improved porous implant wherein the pores of the implant present a second modeling
material on their surfaces. This second material provides a textured or roughened
face to the internal surfaces of pores. Additionally, this second material can
be incorporated in sufficient quantity to, among other things, create a microporous
network connecting interior closed cell pores with the exterior of the device.
