摘要:
Treatments and devices for generating and using interleukin-1 receptor antagonist (IL-1ra). An implantable device is loaded with adipose tissue and/or white blood cells and inserted into an inflammation site in a patient to produce interleukin-1 receptor antagonist in vivo. The implantable device has an enclosed or substantially enclosed body that defines an internal space. At least a portion of the body comprises a first bioresorbable material and a second bioresorbable material is within the internal space along with one or more voids. The second bioresorbable material includes an activation surface to activate adipose tissue and/or white blood cells loaded into the device to produce IL-1ra.
