Abstract: A medical insertion device includes an introducer assembly, a needle, and a housing. The introducer assembly includes a dilator coaxially disposed in a sheath, the dilator removably engaged to the sheath in an insertion configuration. The needle is coaxially disposed in the dilator, the needle having a distal tip and a proximal end coupled to a needle hub. The housing may be removably engaged to the dilator. The needle hub is movably disposed in the housing between a first locked position, a second locked position, and a third locked position.

Abstract: The present invention provides an exercise apparatus having a frame that extends between a front end and a rear end, and is designed to rest upon a floor surface. The frame supports an inclined rail at an angle of greater than five degrees relative to the floor surface. A seat is slidably secured relative to the rail, and the angle of inclination opposes rearward movement of the seat. A load resistant line means is secured at one end to the seat and at another effective end relative to the frame to further oppose rearward movement of the seat.
