Abstract: An intravascular miniature stent pump comprising an intravascular stent for implantation at an implant site within a blood vessel and a miniature pump mounted on the stent, wherein the pump allows an adequate blood flow to prevent clotting within a lumen of the stent, and wherein the blood flow is equal to or greater than a blood flow at the implant site before implantation.

Abstract: Golf club putter that has a raised center of gravity, to allow hitting a golf ball at an improved spot. The raised center of gravity is done by either changing the shape of the putter head, or the material layout of the putter head.

Abstract: An improved putter including a pair of runners attached to the bottom of the putter head. The runners take up less than the entire surface of the bottom of the golf club. They raise the blade of the putter above a ground surface. Their surface area is less than that of the bottom of the golf club, so the interaction with the ground is significantly reduced. This minimizes the interaction between the putter's blade and the ground during putting. The chances that the putter squarely strikes the ball without catching on the ground is increased. The runners also raise the blade to a level to at or near the golf ball's equator. This improves the probability of the blade striking the ball with an upward blow during a swing. The upward blow imparts a desirable top-spin roll on the ball. Undesirable spins which make the ball deviate from its intended path, such as back spin or side spin, are eliminated.
