An implant for the closing of defect openings in the body of a human or animal is proposed, with a load-bearing structure which, in a first operating state (primary form), has a great ratio of length to transverse extent along an axis (9) and, at least in a further operating state (secondary form), has a much smaller ratio of length to transverse extent along the axis (9), the load-bearing structure (1) being capable of being reversibly transformed from the secondary form into the primary form by exertion of a force against elastic material forces, the secondary form assuming approximately the form of a double disc with a proximal disc element (7) and a distal disc element (6) for receiving the surroundings of the defect opening between the disc elements, and the load-bearing structure (1) being formed essentially in one piece without joining connections, and a placement system.

A vial access transfer set for use with a bottle containing a medicinal fluid that provides a mechanism for securely attaching an administration set to the bottle and also provides a universal spike port to which any primary IV line can be readily attached. The vial access transfer set includes a novel, vented vial access adapter to which a length of tubing can be connected, the adapter comprising a top wall, a cannula connected to the top wall and a uniquely configured, resiliently deformable slitted skirt connected to the top wall and extending therefrom. With this construction, during the interconnection of the vial access transfer set with the bottle, the rubber septum of the bottle can readily be pierced by the cannula and the resiliently deformable skirt positively snapped into place over the neck portion of the drug vial or bottle to maintain the adapter in secure connection with the bottle. The apparatus is easy to use and positively prevents the accidental separation of the length of tubing carrying the medicinal fluid from the bottle.

A beverage maker is disclosed with a removable filter carrier, a receiver for the removable filter carrier, and a locking mechanism to selectively secure and seal the carrier to the beverage maker by way of lifting the carrier to engage a sealing surface. In use, the filter carrier is linearly inserted into the receiver via a front face of the beverage maker. The receiver may also include the locking mechanism. The locking mechanism includes a lever that is actuated to operate the locking mechanism. Actuation of the lever is translated to lift and clamp the filter carrier against the seal surface. In the ‘sealed’ position, the lever is selectively fixed in place until the user actuates the lever so as to release the filter carrier. In the ‘released’ position, the filter carrier is still supported by the locking mechanism but it may be selectively removed from the receiver. The locking mechanism reduces or eliminates conventional issues with securing a filter carrier to a beverage maker such as properly aligning the filter carrier so that it may be secured to the beverage maker, the filter carrier disengaging from the beverage maker during use, or not being able to remove the filter carrier after a brew cycle.
