1. A method of augmenting and/or reconstructing an anatomical shape, the method comprising acts of:
(a) positioning an implantable prosthesis including a three-dimensional, tissue infiltratable body of biocompatible material within an anatomical space, the body including a proximal end, a distal end spaced from the proximal end, and a hollow core extending through the body along a core axis from the proximal end to the distal end, the body including a plurality of chambers circumferentially arranged around the core axis, each of the plurality of chambers extending in a corresponding outward radial direction away from the hollow core;
(b) inserting a vascular flap pedicle of fascia along with corresponding blood vessels into the hollow core of the body; and
(c) positioning the blood vessels along the hollow core to provide capillary blood supply to the plurality of chambers.
2. The method according to claim 1 , wherein act (c) includes positioning the vascular flap pedicle in a distal portion of the body.
3. The method according to claim 1 , further comprising an act (d) of securing the proximal end of the body to fascia within the anatomical space.
4. The method according to claim 1 , further comprising an act (e) of placing autologous tissue in the plurality of chambers.
5. The method according to claim 4 , wherein the autologous tissue includes liposuctioned fat.
6. The method according to claim 4 , wherein act (e) is performed prior to act (a).
7. The method according to claim 4 , wherein act (e) is performed after act (a).
8. The method according to claim 4 , wherein act (e) is performed prior to and after act (a).
9. The method according to claim 1 , wherein the method includes augmenting and/or reconstructing the anatomical shape of a human breast.
