Abstract: A Luer-activated valve constructed of a single-piece valve element with integral biasing base and ventilated riser disposed within a valve housing providing a valve seat and buttress for the biasing base.

Abstract: A flow control device in which a flow channel includes a flow control member in the form of a domed disk with legs by which the disk is seated to seal the channel. The control member can be acted upon by an internal actuator or plunger that extends into the flow channel where the plunger can be engaged by an external member such as a Luer fitting. The actuator or plunger may be of rigid or flexible construction.

Abstract: A flow control device in which flow channels converge in a housing containing an injection site and a pre-biased flow control diaphragm. The injection site may include a diaphragm. The diaphragm can be acted upon by an internal actuator or plunger that extends into one of the flow channels where the plunger can be engaged by an external member such as a Luer fitting. The actuator or plunger may be of rigid or flexible construction is at the entry position of an intermediate channel and extends to an output channel of the injection site.

Abstract: An endometrial sampler is provided for obtaining an endometrial sample for clinical analysis which is safe to use and reduces patient discomfort. The sampler includes a handle and a flexible plastic probe having grooves on diametrically opposite sides adjacent the distal end of the probe. Each groove has a pair of sharp edges with each edge formed at the intersection of the periphery of the probe and a sidewall of the groove with the two forming an acute angle at their intersection. The probe is of solid plastic, relatively small in diameter and can be bent before insertion into the uterus of a patient to reduce patient discomfort.
