Claim:
1. A biodegradable implant, said implant comprising: a tubular biodegradable case comprising a bioabsorbable polymer, said biodegradable case having a first longitudinal end, a second longitudinal end, and a wall, wherein the wall extends along a longitudinal axis between the first longitudinal end and the second longitudinal end, wherein the wall includes a first portion comprising a plurality of pores having a designed first pattern of distribution such that the designed first pattern of distribution comprises a first sub-portion having designed pores and a second sub-portion not having designed pores, wherein each of the first sub-portion and second sub-portion covering a contiguous section of the wall and extending substantially from the first longitudinal end to the second longitudinal end, and a second portion, wherein the second portion of the wall has no designed pattern of distribution of pores, wherein the second portion covering a contiguous section of the wall and extending from the first longitudinal end to the second longitudinal end, wherein the second portion is wider than a widest one of the second sub-portion along a width perpendicular to the longitudinal axis, and wherein the case is designed to at least partially surround an absorbable matrix and protect the absorbable matrix from a substantial portion of compression forces, wherein the first portion with the first pattern of distribution of the plurality of pores extends along about one-half of the wall.
