A golf driver has a head which includes an alpha-beta titanium alloy body and a crown formed of a beta titanium plate which is thinner than the body and brazed to the body. The face of the club head comprises a variable-thickness beta titanium faceplate that is plasma welded to the body. Heat generated during the plasma welding causes the thin border region of the faceplate to become even more flexible to enhance the spacing action of the faceplate. Two weights are attached at the toe and heel, respectively, of the body to minimize twisting of the body during an off-center hit. Two additional weights are disposed in the sole of the body in locations causing the center of gravity to be displaced toward the heel and the back side of the club head. A graphite shaft of the driver has at least four sections of different stiffness, defining three bending points, to increase the flex action of the shaft and enable an oversized driver to return to an address position at the moment of impact.

An ultrasound simulator to train radiologists and technologists to locate and recognize patent and fused cranial sutures. The model is formed, for example, using specially fabricated heads or from life-sized plastic doll heads. Simulated suture lines are cut in the heads in anatomically correct positions. The typical end-to-end morphology of the sagittal and metopic sutures and the typical beveled appearance of the paired coronal and lambdoid sutures are created by angling the cutting blade. The hypoechoic appearance of patent sutures in ultrasound images is simulated by filling the gaps that were formed by cutting with a hypoechoic material. Fused echoic sutures are simulated by leaving that portion of the doll's head uncut, or by filling the openings with an echoic material. When imaged using ultrasound, the portions cut and filled with a hypoechoic material are readily distinguishable from uncut portions, and from portions cut and filled with an echoic material.

A stent-graft has a closed web end configuration in which endmost stent crowns do not extend beyond an end or edge of a tubular graft. In order to couple the stent-graft to tip capture fingers or prongs of a delivery system, the stent-graft includes a ring woven between the endmost crowns of an end stent. When end stent is in a compressed delivery configuration, sections of the ring between adjacent endmost crowns form attachment loops that longitudinally extend beyond the end of the tubular graft for engaging the tip capture fingers of a delivery system. When the end stent is in an expanded fully deployed configuration, the attachment loops retract back to the stent so that the ring is a circular band having a diameter substantially equal to the expanded diameter of the stent.
