Abstract
An improved new method of making a multi-component implant comprising a solid hydrogel, a porous hydrogel, and a porous rigid base suitable for implantation into a mammal, to treat, repair or replace defects and/or injury biological tissue as well as the implant made from the improved method. The invention also includes an improved method for making devices, constructs, and materials comprising a hydrogel and a porous rigid material. The invention also includes a mold and kits for performing the methods.
Claims12
A method of making, manufacturing and/or producing an implant suitable for implantation into a mammal for the treatment, repair or replacement of defects or injury in biological tissue, comprising the steps of:
- a. placing a porous rigid base into a well in a mold;
- b. placing a porous hydrogel in the well on top of the porous rigid base;
- c. placing a first lid on the mold;
- d. introducing or injecting a first polymer into the well of the mold;
- e. freezing the mold to about −20° C. for about 4 to 24 hours and subsequently thawing the mold at about 23° C. for about 4 to 12 hours;
- f. removing the first lid;
- g. placing a second lid on the mold;
- h. introducing or injecting a second polymer into the well of mold;
- and
- i. freezing the mold to about −20° C. for about 4 to 24 hours and subsequently thawing the mold at about 23° C. for about 4 to 12 hours.
