The implants may be made of different materials or made in different configurations such that such that a measured property at a first location on said implant is different than said same measured property at a second location on said implant. In one particular embodiment the implants may be a cosmetic penile implant. ## Claims ### Claim 1 An implant suitable for a desired animal or human body part or portion thereof wherein the implant comprises an implant body comprising one or more biocompatible materials wherein said one or more materials are selected or configured to facilitate tissue expansion while not substantially inhibiting normal anatomical movement and wherein said one or more biocompatible materials comprise internal pockets of inaccessible enclosed void spaces within the implant body configured such that a measured property of hardness at a first location on said implant is different than said same measured property at a second location on said implant. ### Claim 2 (depends on 1) The implant of claim 1 wherein at least one additional measured property at a first location on said implant is different than said same measured property at a second location on said implant. ### Claim 3 (depends on 2) The implant of claim 2 wherein said additional measured property comprises one or more of the following properties: (1) tensile strength; (2) tear strength; (3) compressive strength; and (4) elongation. ### Claim 4 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having both linear and radial compression capability. ### Claim 5 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having a durometer range of from about 0 to about 70 durometer on the Shore A scale. ### Claim 6 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having a tensile strength of from about 200 psi to about 800 psi. ### Claim 7 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having an elongation of from about 600% to about 1200%. ### Claim 8 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having a tear strength of from about 40 pounds per inch (ppi) to about 130 ppi. ### Claim 9 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having a compressibility and extensibility factor of up to about 25%. ### Claim 10 (depends on 1) The implant of claim 1 wherein said implant comprises one or more biocompatible materials having two or more of the following: (1) a durometer range of from about 0 to about 70 durometer; (2) a tensile strength of from about 200 psi to about 800 psi; an elongation of from about 600% to about 1200%; (3) a tear strength of from about 40 ppi to about 130 ppi; and (4) a compressibility and extensibility factor of up to about 25%. ### Claim 11 (depends on 1) The implant of claim 1 wherein said implant further comprises a hydrophilic agent. ### Claim 12 (depends on 1) The implant of claim 1 wherein said implant comprises a wall having a varying wall thickness. ### Claim 13 (depends on 1) The implant of claim 1 wherein said internal pockets vary in one or more of the following: geometry, size, depth, or location. ### Claim 14 (depends on 13) The implant of claim 13 wherein the said internal pockets are configured to result in one or more of the following: (1) reduce rigidity of at least a portion of the implant, (2) reduce the total weight of the implant, (3) increase elasticity of at least a portion of the implant, (4) increase extensibility of at least a portion of the implant, or (5) increase compressibility of at least a portion of the implant. ### Claim 15 (depends on 13) The implant of claim 13 wherein said internal pockets comprise those selected from compression pockets, elongation pockets, or both. ### Claim 16 (depends on 15) The implant of claim 15 wherein said internal pockets permit stretching of up to 500% compared to the same implant substrate (e.g., same polymer in same shape) without internal pockets. ### Claim 17 (depends on 1) The implant of claim 1 wherein said internal pockets comprise a honeycomb design. ### Claim 18 (depends on 1) The implant of claim 1 wherein said biocompatible material comprises a material that releases heat. ### Claim 19 (depends on 1) The implant of claim 1 wherein said biocompatible material comprises a material that absorbs heat. ### Claim 20 (depends on 1) The implant of claim 1 wherein one or more biocompatible materials have two or more of the following: (1) a durometer range of from about 10 to about 70 durometer; (2) a tensile strength of from about 200 psi to about 800 psi; an elongation of from about 600% to about 1200%; (3) a tear strength of from about 40 ppi to about 130 ppi; and (4) a compressibility and extensibility factor of up to about 25%. ### Claim 21 (depends on 1) The implant of claim 1 wherein the implant is configured in the form of a penis, testicle, or a breast. ### Claim 22 (depends on 1) The implant of claim 1 wherein the implant is configured in the form of a breast.
