Methods of monitoring and evaluating the status of a tumor undergoing treatment includes monitoring in vivo at least one physiological parameter associated with a tumor in a subject undergoing treatment, transmitting data from an in situ located sensor to a receiver external of the subject, analyzing the transmitted data, repeating the monitoring and transmitting steps at sequential points in time and evaluating a treatment strategy. The method provides dynamic tracking of the monitored parameters over time. The method can also include identifying in a substantially real time manner when conditions are favorable for treatment and when conditions are unfavorable for treatment and can verify or quantify how much of a known drug dose or radiation dose was actually received at the tumor. The method can include remote transmission from a non-clinical site to allow oversight of the tumor's condition even during non-active treatment periods (in between active treatments). The disclosure also includes monitoring systems with in situ in vivo biocompatible sensors and telemetry based operations and related computer program products.

Decision information systems, methods, and computer programs for better informing decisions to use multiple drugs in drug delivery devices, including implantable devices, for drug administration. Executable computer programs and logic embodying methods of the invention can calculate consistent multiple drug mixture amounts and drug delivery flow rates. One program accepts user input indicating a desired first drug dose rate, an initial first drug concentration, a desired second drug dose rate, an initial second drug concentration, and the reservoir size of the drug delivery device. The program method calculates a first drug amount and a second drug amount to combine in a mixture as well as a first drug true concentration in the mixture. The drugs can be mixed consistent with the physician's instructions using the program output. The first drug true concentration can be entered into a programmer device as the only drug concentration entered. Another program calculates a consistent first drug, second drug, and diluent amount to be added to a mixture for injection into a fixed flow rate, implantable drug delivery device. Methods preferably output true concentrations and dose rates for all drugs to be added and most preferably show all calculations used to arrive at the flow rate and mixture amount calculations. Yet another program receives a new desired drug dose rate for a previously filled device. The program accepts the existing mixture volume and true drug concentrations for a partially depleted device and calculates a new mixture flow rate to achieve the desired dose rate using the existing mixture. The methods can be implemented as executable computer programs in programmer devices, general purpose computers, servers, handheld computers, and personal digital assistants.

A closed loop system for monitoring drug dose, intake and effectiveness includes a drug delivery device in data communications with at least one implantable medical device.

A mechanical injection device (1) for injecting apportioned doses of liquid drug. The injection device (1) comprises a dose setting means, an injection means, a removable cap (15) and a cap receiving part (9) adapted to abut or engage with the cap (15) when the cap (15) is mounted on the injection device (1). The dose setting means is operatively coupled to the cap receiving part (9) in such a manner that mounting and / or dismounting of the cap (15) on / from the injection device (1) causes the dose setting means to set a dose. Thereby a correct dose of drug is automatically set during a cap on / cap off cycle. Since such a cycle is normally performed between two subsequent injections, the number of steps required to be performed by the user is reduced.

Dry powder inhalers with integrated active energy patient assist dispersal systems are configured with control systems which provide adjustable energy output responsive to the user's inspiratory capabilities and / or the flowability of the dry powder drug being administered. The multi-dose dry drug package includes a piezoelectric polymer substrate (such as PVDF) which flexes to deform and provide mechanical oscillation in a selected region of the package corresponding to the dry powder drug dose in the exit flow path and is thus actively dispersed into the exit flow path of the inhaler during the user's inspiratory activity. Control systems employ fuzzy logic models of the flowability of particular drug formulations (also being able to compensate or allow for the particular type of excipient used) and / or adjust for the real-time measured inspiratory efforts of the user. Manufacturing process control systems can adjust certain parameters in response to a fuzzy logic model of the flowability of the dry powder and other conditions associated with the dry powder drug being produced and / or dispensed.

The present invention relates to a medicament delivery device such as an injector for self-administration of a medicament. Those using such devices are often infirm or have impaired vision. There is accordingly a dead for a medicament delivery device in which an amount of a dosage of medicament to be delivered can be selected relatively quickly by the firm and infirm alike and in which the amount of the dosage may readily be controlled and determined. Also there is a need to display the amount of the dialed dosage of medicament on the rotatable knob in figures sufficiently large and clear to be legible by those having a degree of impaired vision. There is disclosed a dose dial mechanism for a medicament delivery device having a housing, the dose dial mechanism comprising a dose dial element having a first thread for engagement with the housing and a dial sleeve member having a second thread for engagement with the housing; in which the dial sleeve member is coupled to the dose dial element so as to allow relative axial movement and inhibit relative rotational movement therebetween, and in which the pitch of the second thread is different from the pitch of the first thread so as to cause a different axial displacement of the dial sleeve member during axial displacement of the dose dial element.
