Abstract: The present invention provides an improved cannula that can be used to reconstitute powdered drugs in a drug delivery system. Furthermore, the present invention provides a cannula and drug delivery system incorporating same. To this end, the present invention provides a cannula structure for use in a reconstitution device for reconstituting a powdered drug comprising a cannula having a first end and a second end, and defining a channel in an interior thereof between the first and second ends. The first end is closed and includes a member for piercing a septum. The cannula includes at least two slots providing fluid communication between the channel and an exterior of the cannula. The slots are located in juxtaposition to the first end and have a width, as measured along a length of the cannula, that is less than a length, as measured around the cannula. The slots also have a minimum projected area equal to or greater than the cross-sectional area of the channel.

Abstract: An apparatus (60) and system (20) are disclosed for the patient-controlled delivery of an analgesic or other beneficial agent 142, while preventing administration of a toxic quantity of the beneficial agent. The invention permits delivery of fractional doses to a patient in quantities which are directly proportional to the time period since the last dose or fraction thereof was delivered to the patient. In the preferred embodiments the apparatus includes a housing (58) including a casing (88) and a back plate (86), the housing containing a control switch (84) for opening and closing downstream conduit (62) and for depressing a floating plate (100) that thereby compresses a dose reservoir (90) with the beneficial agent (142) therein. A spring (124) biases the control switch (84).

Abstract: A connector device (10) for establishing fluid communication between a first container (12) and a second container (14) is described. The device comprises a first sleeve member (30) having a first end (40) and a second end (42) and a means at the first end for attaching to the first container. The device also comprises a second sleeve member (32) having a first end (80) and a second end (82). The second sleeve member is associated with the first sleeve member and movable in an axial direction with respect thereto from an inactivated position to an activated position. The second sleeve member also comprises at the second end a means for fixedly attaching to the second container. The device is provided with first (34b) and second (34a) piercing members projecting from one of the first and second sleeve members for providing fluid flow from the first container to the second container. A method of connecting a reconstitution device (10) to a drug container (14) having a top and a closure (24, 26) is also described as is a method of reconstituting a drug contained in a second container (14) with a diluent contained in a first container (12).
