Abstract
The present disclosure relates to reticulated elastomeric matrices, and more particularly to at least partially degradable elastomeric elements that are compressible and exhibit resilience in their recovery and that can be employed in diverse applications including, without limitation, biological implantation, especially in humans.
Claims17
A reticulated matrix comprising (a) a soft segment comprising a polycaprolactone copolymer polyol and (b) a hard segment comprising an isocyanate having cross-linking and optionally having a chain extender, the reticulated matrix having a continuous-interconnected void phase, wherein the reticulated matrix is configured to be implantable and at least partially degradable, wherein the continuous-interconnected void phase extends from an interior portion to an exterior surface of said matrix;
- wherein a path through the void phase can be drawn in a substantially linear direction across an entirety of said matrix beginning at any portion of an exterior surface of said matrix containing said void phase.
A process of making a reticulated matrix comprising a foaming by reacting isocyanate with polyol in presence of a blowing agent to form a porous reaction product, and thermally reticulating of the porous matrix to form the reticulated matrix, wherein the reticulated matrix is configured to be implantable and at least partially degradable wherein the reticulated matrix having a continuous-interconnected void phase, wherein the continuous-interconnected void phase extends from an interior olio to an exterior surface of said matrix;
- wherein a path through the void phase can be drawn in a substantially linear direction across an entirety of said matrix beginning at any portion of an exterior surface of said matrix containing said void phase.
