Abstract: An exemplary device includes a processor, one or more communication interfaces, memory and one or more modules stored in the memory that comprise processor executable instructions to receive data from an implantable device via at least one of the one or more communication interfaces, to interrogate the data for one or more particular types of data, to process one or more particular types of data and to transmit information via at least one of the one or more communication interfaces. Various other exemplary devices, methods, systems, etc., are also disclosed.

Abstract: Techniques are provided for use with a pacemaker or other implantable medical device for detecting arterial blood pressure. Briefly, the pacemaker detects aortic electrical resistance using sensing/pacing leads. Aortic electrical resistance pertains to the resistance to an electrical current passing through the aorta. The pacemaker then determines the arterial blood pressure of the patient based on the aortic resistance and a predetermined calibration value that relates aortic resistance to arterial pressure. The calibration value is updated monthly based on blood pressure values detected using an external blood pressure sensor employing a blood pressure cuff. Other techniques described herein pertain to the determination of other physiologic parameters such as stroke volume and cardiac output and to the detection of changes in hematocrit. Any of the various physiological parameters may then be used to trigger or control warning signals and responsive therapy.

Abstract: A disposable pumping cassette having an integral auxiliary flow control and pressure monitoring member is used for delivering a medicinal fluid to a patient. The pumping cassette includes an elastomeric member mounted in a rigid body having an inlet and an outlet. An inlet valve and an outlet valve on the cassette are opened, and the flow control is positioned to allow the medicinal fluid to flow freely through the cassette, priming it before the outlet is connected to the patient. The cassette is then coupled to an associated pump driver, closing the flow control to disable free fluid flow through the cassette, and the outlet to the cassette is coupled in fluid communication with the patient's body.

Abstract: A modular ambulatory infusion pump comprises a base unit including an integral housing, said base unit including an infusion pump for infusing fluid into a patient's body, a battery power supply for energizing infusion pump and a control for operating the infusion pump to achieve at least one of a desired rate, a desired volume and a desired time interval for infusing the fluid. Disposed on the integral housing is a first electrical connector, said first electrical connector being provided to electrically couple the base unit to a mating connector on one of the plurality of modules, said one of the plurality of modules being coupled to the base unit to add a selected additional port to the base unit and to provide additional capability, said plurality of modules including a data port module that includes a printer interface port.

The cassette is then coupled to an associated pump driver, closing the flow control to disable free fluid flow through the cassette, and the outlet of the cassette is coupled in fluid communication with the patient's body. The medicinal fluid is drawn into a pumping chamber formed in the rigid body as a plunger of the associated pump driver is drawn up from the elastomeric membrane at a recess formed in the rigid body.

Abstract: A push button flow stop is mounted on a disposable infusion pumping cassette provided for use with a drug infusion pump. The flow stop is operative to enable or to block fluid flow through the cassette in a first mode and to monitor fluid pressure in the cassette in a second mode.
