Abstract:
1. A bioresorbable wall reinforcement implant comprising: a bioresorbable porous matrix including a collagen sponge which defines first pores, a bioresorbable porous three-dimensional knit which defines second pores, said porous matrix filling said three-dimensional knit and all the first and second pores being at least partially interconnected with one another, wherein said collagen comprises a mixture of at least one glutaraldehyde-crosslinked collagen which undergoes slow bioresorption in vivo having a degradation time ranging from approximately 3 months to about 12 months and at least one oxidized collagen which undergoes rapid bioresorption in vivo having a degradation time of up to approximately 8 weeks, wherein a concentration of the at least one glutaraldehyde-crosslinked collagen and the at least one oxidized collagen is provided at a ratio between 1:5 and 5:1.
