Abstract: A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.

Abstract: A door power drive module includes a housing and a motor arranged in the housing. First and second gearboxes are arranged in the housing and are coupled in series with one another by a shaft member. The first gearbox connects the motor to the second gearbox. An output shaft is coupled to the second gearbox. A brake assembly is selectively connected to the shaft member. The brake assembly has a normally closed position in which the shaft member is grounded to the housing. The brake assembly includes an open position corresponding to one of a door closing mode and a door opening mode. The shaft member is configured to be rotatable relative to the housing in the brake open position in response to the motor driving the first gearbox. The brake assembly includes a holding torque in the normally closed position. A torque is applied to the brake assembly above the holding torque that permits the shaft member to rotate in any direction of rotation.
