Abstract: A golf swing muscle strengthener apparatus (90) for strengthening the muscles used in the downswing of the golf swing. The apparatus includes a swing plane adjustment element (50) secured at an adjustably elevated position above the ground by a frame element (20) and support arm element (40). The swing plane adjustment element (50) houses a swing arm assembly (70) adjustable to various swing plane positions. The swing arm assembly (70) is operatively coupled to a resistance means, and has a swing arm (63) shaped to circumvent the golfer's upper torso and head. The swing arm (63) exhibits pivotal rotation around a central axis of rotation and has a pad element (80) attached at its distal end for accepting the golfer's forearm. The golfer's forearm presses against the pad element (80) at the peak of the backswing, and rotates the swing arm assembly (70) during the downswing phase of the golf swing.

Abstract: A stent and stent catheter for intra-cranial use. The stent is a rolled sheet stent and is releasably mounted on the distal tip of the catheter by means of a non-sliding retention and release mechanism. The non-sliding release mechanism is operated remotely at the proximal end of the catheter by means of a linear translator. The stent is rolled tightly on the distal tip of the catheter and flexibility of the tightly rolled stent is promoted by ribbed or slatted construction (or, alternatively, slotted construction) in which the various layers of the stent are provided with numerous slats which counter align when the stent is expanded to form an imperforate wall from a plurality of perforate layers.
