Stryker Corporation, the artifical hip manufacturer, has received a subpoena regarding the agency’s probe into Stryker’s sale of medical device prodcuts to foreign countries. Stryker was one of five medical device companies to settle with the federal government and avoid prosecution over kickbacks to doctors in exchange for using their hip implants. Stryker has been in the news recently after it recalled its Trident PSL and Trident Hemispherical Acetabular Cups used in hip replacement surgery. Stryker has known about problems with the hip devices since at least January 2005 when it began receiving complaints from patients who had received the hip replacement devices. The problem with the hip replacement components are two-fold involving manufacturing processes as well as issues regarding defective design.
