A Y-shaped stent, or bifurcated stent, for stenting bifurcated vessels consists of a first generally cylindrical distal branch defining a first flow path for fluid flow, and a second generally cylindrical distal branch defining a second flow path for fluid flow. The first and second distal branches

A Y-shaped stent, or bifurcated stent, for stenting bifurcated vessels consists of a first generally cylindrical distal branch defining a first flow path for fluid flow, and a second generally cylindrical distal branch defining a second flow path for fluid flow. The first and second distal branches are interconnected by one or more bending elements at a carina junction, each of the bending elements being flexible such that the first and second distal branches are capable of pivoting about the bending elements at the carina junction, thus defining an angle of varying degree. A generally cylindrical proximal branch defines a third flow path for fluid flow. The proximal branch is attached to the first and second distal branches proximate the carina junction such that the first and second distal branches and the proximal branch are in communication with each other.

The accessory of claim 1 wherein said tee height setting device includes: a mounting bracket mounted to a housing of said ball teeing mechanism for undergoing pivotal movement relative to said housing between an upwardly extending storage position and a downwardly extending use position; a tee height adjusting element mounted to said mounting bracket so as to undergo rotation in order to move said element longitudinally along said mounting bracket; and a pair of guide pins mounted on said mounting bracket in a generally side-by-side relation with one another and adjacent to said tee height adjusting element and extending outwardly beyond said mounting bracket and said tee height adjusting element such that said guide pins can be pushed into the ground until said tee height adjusting element contacts the ground to set the height at which the tee will be implanted into the ground by the ball teeing mechanism. 3. The accessory of claim 2 wherein said guide pins are also adapted to be inserted into the ground for replacing and repairing divits in a playing surface. 4. The accessory of claim 2 further comprising: an annular quiver element fitted over said shaft and having at least one radial slit therein; and a ball marking element removably fitted into said one slit of said quiver element, said ball marking element having a tab with an opening which can receive an end of one of said guide pins to place said ball marking element on the ground and also to pick up said ball marking element from the ground. 5. The accessory of claim 1 wherein said ball retrieving device includes: an elongated member pivotally attached at one end to a housing of said ball teeing mechanism; and an expandable element attached to an opposite end of said elongated member and being capable of flexing so as to fit around a ball in the cup and underlie the ball for lifting the ball from the cup. 6. The accessory of claim 5 further comprising: a lying tee retrieving device pivotally mounted to said elongated member of said ball retrieving device and being mo
