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.
Claims8
A resorbable spinal 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;
- wherein the member is operable to be positioned between a first vertebrae and a second vertebrae.
