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

An apparatus for delivering a bolus of a medical agent to a patient. The apparatus comprises a pump mechanism, a data input device, and a processor in data communication with the keypad and arranged to control the pump mechanism. The processor is programmed to receive data specifying a bolus amount through the data port, receive data regarding duration through the data port, receive a percentage through the data port, the percentage defining a portion of the bolus amount to deliver immediately upon executing a deliver command and a remainder of the bolus amount to deliver over the duration upon executing a deliver command, and execute the deliver command thereby controlling the pump mechanism to deliver the bolus. Also a method of temporarily adjusting the delivery rate of an infusion pump. The infusion pump is programmed to deliver a basal rate. The method comprises prompting a user to select whether to enter the temporary rate as a percent of the current delivery rate or as a new delivery rate; entering into the pump a period of time having a beginning and an end; entering into the pump a temporary basal rate; and delivering the therapeutic agent at a delivery rate substantially equal to the temporary basal rate during the period of time.

Systems and methods for continuous measurement of a medicament in vivo are provided. In some embodiments, the system is configured to provide information associated with medicament titration and includes a continuous analyte sensor and a communication device. In some embodiments, the system is configured for continuous ambulatory drug testing, including an ambulatory host monitor having a continuous sensor, a location module, a processor module and a transmitter. In some embodiments, the system is configured for continuously monitoring a hormone level and includes a continuous hormone sensor and a communication device configured to output hormone information in real time. Yet another embodiment provides an analyte sensor for continuous monitoring of a host's nutritional status, and is configured for both continuous glucose detection and continuous albumin detection.

A system, method and program are disclosed for achieving rapid bit synchronization in low power medical device systems. Messages are transmitted via telemetry between a medical device and a communication device. The synchronization scheme uses a portion of a unique preamble bit pattern to identify the communication device allowing for economical communications with a minimum expenditure of energy. A special set of preamble bit patterns are utilized for their unique synchronization properties making them particularly suited for rapid bit synchronization. These unique preamble bit patterns further provide simplification to the preamble error detection logic.

A control system for controlling an infusion pump, including interface components for allowing a user to receive and provide information, a processor connected to the user interface components and adapted to provide instructions to the infusion pump, and a computer program having setup instructions that cause the processor to enter a setup mode upon the control system first being turned on. In the setup mode, the processor prompts the user, in a sequential manner, through the user interface components to input basic information for use by the processor in controlling the infusion pump, and allows the user to operate the infusion pump only after the user has completed the setup mode.

A piston-type infusion pump is provided having an improved method of occlusion detection. The infusion pump includes processing circuitry for controlling the drive mechanism to infuse medication to a patient, including a sensor to track the position of the syringe plunger, thereby metering the amount of medication dispensed to the patient. The processing circuitry also includes a force sensor for providing signals indicative of the presence of occlusions along the infusion path. The operation of the drive mechanism causes delivery of medication to the patient. The infusion pump is constructed to be watertight.

A medication delivery system (20) having features of the present invention comprises a medical container (26) holding a prescribed medication (27) to be delivered to a patient, a tag 24 adapted to be worn by the patient, a handheld computing device (22), and an electronic medication delivery device (30). Data on the medication (27) is contained in a first label (28) on the medication container (27). The first label (28) also contains the instruction on how the medication is delivered to the patient, including the appropriate settings for an electronic medication delivery device for delivering the medication to the patient. Patient data is contained in a second label (29) on the tag (24) worn by the patient. The medication data, medication delivery instruction, and patient data are provided in machine readable formats. The handheld computing device (22) reads the medication data and the medication delivery instruction on the medication container (26) and the patient data on the patient tag (24). The handheld computing device (22) stores the information obtained and performs a matching check to confirm that the medication data matches with the patient data. Upon a confirmed match, it transmits the medication delivery instruction to the electronic medication delivery device (30), which downloads the instruction, programs the delivery device 30, and prompts an operator to begin delivering the medication (27) to the patient according to the downloaded instruction.

A drug administration controller has a sensor that generates a sensor signal to a physiological measurement device, which measures a physiological parameter in response. A control output responsive to the physiological parameter or a metric derived from the physiological parameter causes a drug administration device to affect the treatment of a person, such as by initiating, pausing, halting or adjusting the dosage of drugs administered to the person.
