Abstract
A device for relieving synovial fluid pressure in a capsule surrounding a body joint includes a valve for placement in the capsule surrounding the joint for regulating passage of synovial fluid from the capsule. The valve can include a valve housing defining a passage between an interior and exterior of the capsule and a valve member disposed within the valve housing for regulating synovial fluid pressure within the capsule by permitting synovial fluid to drain from the capsule when a predetermined synovial fluid pressure is exceeded. The valve housing can be secured to the capsule with inlet and outlet flanges disposed at opposite ends of the housing and, additionally, by use of openings formed in the outlet flange to allow passage of sutures and to promote integral tissue fixation over time.
