External infusion device with remote programming bolus estimator and/or vibration alarm capabilities

InactiveUS6551276B1Short and long period of timeTime indicationAutomatic syringesIntensive care medicineTransmitter
An infusion system for infusing a liquid into a body includes an external infusion device and a remote commander. The external infusion device includes a housing, a receiver, a processor and an indication device. The receiver is coupled to the housing and for receiving remotely generated commands. The processor is coupled to the housing and the receiver to receive remotely generated commands and to control the external infusion device in accordance with the commands. The indication device indicates when a command has been received and indicates when the command is being utilized to control the external infusion device so that the external infusion device is capable of being concealed from view when being remotely commanded. The remote commander includes a commander housing, a keypad for transmitting commands, and a transmitter for transmitting commands to the receiver of the external infusion device.

Microprocessor controlled ambulatory medical apparatus with hand held communication device

An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.

Ambulatory medical apparatus and method using a telemetry system with predefined reception listening

An implanted medical device (e.g. infusion pump) and an external device communicate with one another via telemetry messages that are receivable only during windows or listening periods. Each listening period is open for a prescribed period of time and is spaced from successive listening periods by an interval. The prescribed period of time is typically kept small to minimize power consumption. To increase likelihood of successful communication, the window may be forced to an open state, by use of an attention signal, in anticipation of an incoming message. To further minimize power consumption, it is desirable to minimize use of extended attention signals, which is accomplished by the transmitter maintaining an estimate of listening period start times and attempting to send messages only during listening periods. In the communication device, the estimate is updated as a result of information obtained with the reception of each message from the medical device.

Medical devices with enhanced ultrasonic visibilty

A medical device having enhanced ultrasonic visibility is provided. The device permits localized drug delivery, probe positioning, fluid drainage, biopsy, or ultrasound pulse delivery, through the real-time ultrasound monitoring of the needle tip position within a patient. The device permits controlled dispersion of a drug into solid tissue, the lodging of particles into solid tissue, and drug delivery into specific blood vessels. As a needle is inserted, a fluid that contrasts echogenically with the organ environment is injected into the patient. The fluid travels a brief distance before being slowed and stopped by the patient's tissue and this fluid flow will be detectable by ultrasound. The needle position during insertion will be monitored using ultrasound until it is at the desired point of action. A therapeutic drug is then delivered or a probe inserted

Programmable medical drug delivery systems and methods for delivery of multiple fluids and concentrations

A drug delivery system provides for mixing various drugs in an optimally controlled manner, for using flow controllers to guide multiple drugs into a single or into multiple catheters, for enabling a single lumen catheter to treat a specific region with several drugs, for allowing for dilution of a concentrated drug in order to both increase the time between refilling and also for providing any concentration of a drug that might be desired, for using a buffer fluid to deliver exact amounts of several drugs from the same catheter or to separate several drugs within a single catheter, for using external fluid present in the human body either as a diluent or buffer fluid, and for providing for a drug testing / filler apparatus to be used prior to implant to ensure proper function and easy means of filling multiple reservoirs with different fluids, and also after implant for refilling operations. The drug delivery system (DDS) can perform both bolus and continuous delivery of substances, and enable the measured delivery of any one of several drugs to one or more distal locations at independently programmable rates. New types of catheter systems and uses therefore are also described. Catheter hub assemblies allowing for easy replacement of drug delivery systems offer advantages when replacing drug delivery systems. New methods for using the DDS in the promotion of healthy pregnancy and treatment of a developing fetus are also possible.
