A sports bottle includes a generally cylindrical hollow vessel having a liquid chamber formed therein and a closed end bottom. The generally cylindrical vessel further defines a reduced diameter neck portion and an upper chamber terminating in an upwardly facing mouth. The upper chamber supports a porous antisplash element preferably formed of a coarse porous foam material plastic or the like. An elongated tubular straw extends from the bottom surface within the vessel upwardly through the neck portion and through the antisplash element and beyond the mouth to form an upwardly extending end which receives a flexible mouth tube which is preferably curved toward the user when the sports bottle is secured to a conventional bicycle. In alternate embodiments, the antisplash element within the upper chamber of the vessel is formed of a plurality of tubular members defining passages therethrough and grouped together to form a generally cylindrical multipassage combination. In still further alternate embodiments, a flexible planar member having a plurality of flexible generally triangular segments is secured to the mouth portion of the vessel to provide an antisplash element. In a still further alternate embodiment, a generally planar valve member is pivotally supported within the mouth portion of the vessel and is pivoted to an open position as liquid is poured into the vessel mouth.

The invention provides a motor drive unit for use in conjunction with an atherectomy device which limits the torque exerted on a drive cable for rotating a cutting blade in the device. In a preferred embodiment, a motor drive unit includes a motor having a shaft coupled to the drive cable for rotating the cutting blade, a power supply coupled to the motor and a switch for selectively connecting the power supply to the motor. A torque control circuit connected to the power supply and the motor controls the torque exerted by the motor when the switch is closed, whereby the current to the motor is continuously increased from zero to a start-up level, the start-up level being the minimum current sufficient to turn the cutting blade. Usually, the torque control circuit will include a resistor and a capacitor connected to a power supply in parallel with the motor, wherein a gradually decreasing portion of current from the battery is diverted through the RC circuit to charge the capacitor such that the current to the motor is at the start-up level when the capacitor is charged. The motor drive unit further includes a power MOSFET for discharging the capacitor when the switch is opened to reset the circuit.
