Implant devices that differ by release profile and methods of making and using same |
摘要 |
Described herein are implant devices, kits comprising the implant devices, and methods of making and using the devices and kits. In one aspect, a plurality of implant devices comprises at least two implants that exhibit a different release profile of a bioactive agent. In another aspect, an implant device comprises one or more adjoined polymer bodies, wherein at least two of the polymer bodies provide a different release profile of a bioactive agent. In another aspect, a kit comprises one or more disclosed implant devices. In another aspect, methods of delivering a bioactive agent to a subject comprise administering to the subject one or more disclosed implant devices. |

1. An implant device comprising a polymer body having at least two portions that each comprise a bioactive agent therein and/or on a surface thereof, the bioactive agent being releasable from the at least two adjoined portions, wherein a release profile characterizes the release of the bioactive agent from each of the portions and wherein at least two portions differ by release profile by releasing a different amount of the bioactive agent over time, provided that the portions are not adjoined only in a core-sheath configuration, and wherein the polymer body comprises at least two cross-sectional portions; wherein said implant device is in the form of a rod, where at least two cross-sectional portions having different release profiles are formed on one end of the rod; wherein the implant device has a cumulative release profile of the at least two portions and the at least two cross-sectional portions. |
