Abstract
A composite material for positioning in the anatomy to form a selected function therein. The composite may be resorbable over a selected period of time. The composite may allow for selected bone ingrowth as absorption of the composite occurs.

43. A resorbable implant, comprising a member including a composite formed of:
-
a first material comprising a first resorbable material operable to be resorbed into an anatomy, the first material forming a scaffold having a plurality of pores and a plurality of continuous channels defined at least in part by a first sub-plurality of the plurality of pores, the plurality of channels extending through the scaffold; and a second material that is a resorbable polymer injected into the scaffold to substantially fill at least a sub-plurality of the plurality of continuous channels so that the polymer forms a continuous structure; wherein the second material is a polymer selected from the group comprising polylactic acids, polyglycolic acids, and combinations thereof, and forms about 55 wt % to about 65 wt % of the member; wherein the resorbable polymer is resorbed at a rate slower than a rate of resorption of the scaffold such that the resorbable polymer defines a support for bony ingrowth to maintain a selected strength of the member. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)

51. A resorbable implant, comprising a member including a composite formed of:
-
a scaffold of a first material having a plurality of pores in a surface of the scaffold and a plurality of continuous channels interconnecting at least a first sub-plurality of the plurality of pores, wherein the plurality of continuous channels extend through the scaffold between at least two of the plurality of pores; and a resorbable polymer to substantially fill at least a sub-plurality of the plurality of continuous channels so that the polymer forms a continuous structure within the scaffold; wherein the resorbable polymer is resorbed at a rate slower than a rate of resorption of the scaffold such that the resorbable polymer defines a support for bony ingrowth to maintain a selected strength of the member. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58)

59. A resorbable implant, comprising:
-
a single member having; a first material resorbable into an anatomy at a first rate to allow bone ingrowth; and a second material for resorbing into an anatomy at a second rate different than the first rate to support the bone ingrowth; wherein the first material and the second material are distinct and separately combined into the single member by positioning the second material within a structure formed by the first material. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66)
