Abstract: Methods of making an enhanced bioactive PRP implant include supplying a centrifuge container with a collagen-based scaffold pre-inserted onto a moveable filter within the vial. A centrifuge process for creating the PRP implant is followed, resulting in a PRP/collagen implant combination. Other biologics may be added to the container instead of or in addition to the collagen-based scaffold. Additionally, methods of fixing the PRP implant into place at the point of a tear or wound include applying the PRP implant adjacent to or within a meniscal tear, or underneath or on top of a rotator cuff tear. Suture or staples may then be routed either through or over the PRP implant to hold the implant in place.

Abstract: A cryogenic seal for vacuum-insulated pipe systems where the pipe system includes an inner pipe connected to an outer pipe by a bellows. The seal prevents cryogenic liquid from leaking from the inner pipe into the annular vacuum space between the inner and outer pipes in the event of bellows failure. One end of the bellows is connected to the inner pipe by a movable bellows ring and the other end of the bellows is attached to the outer pipe by a fixed bellows ring. A bellows guide is attached to the fixed bellows ring and receives the movable bellows ring in a sliding fashion. The seal may be positioned between the movable bellows ring and the bellows guide or between the fixed bellows ring and the outer surface of the inner pipe. The seal may also be positioned between the bellows shield and the movable bellows ring. The seal may be a leak control ring or the packed gland type.
