Abstract

The present disclosure provides implants suitable for drug delivery. In embodiments, the present disclosure provides layered biodegradable drug delivery implants and systems and methods for making these implants.

Claims (28)

1. A system for forming a coaxial implant, the system comprising:

a first assembly for dispensing a first material;

a second assembly for dispensing a second material;

a sleeve defining first and second ends and defining a cavity therebetween for forming an implant, wherein the first and second ends are configured for operable engagement with each of the first and second assemblies; and

a centering post configured for operable engagement with the sleeve.

2. The system of claim 1 , wherein at least one of the first and second materials include at least one of a therapeutic agent and an active pharmaceutical ingredient.

3. The system of claim 1 , wherein each of the first and second materials comprises a hydrogel.

4. The system of claim 1 , wherein at least one of the first and second assemblies includes a mixing tip.

5. The system of claim 1 , wherein both the first and second assemblies include a mixing tip.

6. The system of claim 1 , wherein the first assembly is configured to mix at least a first and second component.

7. The system of claim 1 , wherein the sleeve includes a zipper for creating a seam in the sleeve.

8. The system of claim 7 , wherein the seam enables removal of the sleeve from about an implant formed therein.

9. The system of claim 1 , wherein the sleeve includes a non-circular cross-sectional profile.

10. A method of forming a coaxial implant, the method comprising the steps of:

providing a system including first and second dispensing assemblies, an implant forming sleeve having two ends, and a centering post;

selectively securing the first dispensing assembly with a first end of the implant forming sleeve and the centering post with a second end of the implant forming sleeve;

activating the first dispensing assembly to deposit a first material within the sleeve and about the centering post to form a first layer of the implant;

separating the centering post from the second end of the sleeve thereby creating a void with the first layer;

selectively securing the second dispensing assembly with the second end of the implant forming sleeve;

activating the second dispensing assembly to deposit a second material within the void to form a core of the implant; and

separating the first and second dispensing assemblies from the sleeve.

11. The method of claim 10 further including the step of removing the sleeve from about the implant.

12. The method of claim 10 , wherein at least one of the first and second materials include at least one of a therapeutic agent and an active pharmaceutical ingredient.

13. The method of claim 10 , wherein each of the first and second materials includes at least one of a therapeutic agent and an active pharmaceutical ingredient.

14. The method of claim 13 , wherein the therapeutic agent and active pharmaceutical ingredient in the first material and the second material are the same or different.

15. The method of claim 10 , wherein at least one of the first and second materials comprises a hydrogel.

16. The method of claim 15 , wherein at least one of the first and second materials comprises a biocompatible polymer.

17. The method of claim 10 , wherein each of the first and second materials comprises a hydrogel.
