Arterial filter

A catheter system in which a silicone rubber catheter tube may be secured to the cylindrically shaped relatively smooth stem of a rigid plastic fitting. A rigid plastic sleeve is adapted to extend over the tube when the latter is fitted onto the stem of the fitting to create a fluid tight seal between the tubing and the fitting. In another embodiment, a boot may first be disposed over a portion of the silicone rubber tubing and then extended over the connection of the rigid sleeve and rubber tubing and plastic fitting. In still a further embodiment a combination boot-sleeve may be employed and sealed to a fitting by means of an ultrasonic weld.

Catheter system

A device including a valving mechanism which can be operated by one hand, the device includes a housing which surrounds a resilient block of material. The housing may be squeezed to depress and deform the resilient block. Passageways extend through the resilient block to conduct liquid therethrough. A first passage includes a solid valve positioned therein. Compression of the resilient block causes displacement of the valve and distortion of the block material to break the seal around the valve. Additional material is provided strategically in this first passage to insure against leaks from system overpressure. A second passage includes a capillary to allow continuous low volume flow not controlled by an operator.
