Abstract: Power and control systems for a drug delivery device allow for the activation, control of, and communication with the drug delivery device. The power and control system allows for a delay between device activation, and optionally needle insertion, and commencing drug delivery. The delay may be for a predetermined time.

The inputs from the sensors and devices may automatically, or on demand, adjust the delivery parameters of the device. The power and control systems may control a drive system that delivers a fluid at a variable rate or profile, allowing for the delivery to be tailored to maximize the effectiveness of the treatment.

Abstract: A clamping mechanism (30) for clamping a flexible tube comprises two rotatable bobbins (22, 32), each with a tube-engaging surface portion (24) defining boundaries of: a free space through which a tube may extend. The shape of: the tube-engaging surface portion (24) changes around the bobbin circumference, such that axial rotation of the bobbins (22, 32) reduces the free space and thereby squeezes the tube. This allows the flow through the tube to be altered dependent on the rotation of: the bobbins.

The first elongate body extends through at least part of the catheter shaft and is configured to move longitudinally in the catheter shaft. The first elongate body is looped through the service loop ring to form a service loop configured to expand and contract as the first elongate body moves longitudinally in the catheter shaft.

Abstract: An extremely lightweight and compact heating system greatly increasing patient mobility is provided. The use of a flat plate can be used to greatly decrease package size and weight while providing comparable heat transfer by exploiting the ability of the dialysis bags to conform to this surface and through the greater heating area possible with the flat plate design. A short rim around the plate provides centering and protecting against minor leakage without substantially increasing package height. Protection against leakage is buttressed by sealing the rim to the plate and the use of 12 V only within the heating unit. The result is a lightweight warming device with a short that can be easily transported by the patient greatly improving patient lifestyle and freedom.

A needle hub can be contained within the barrel and can be retracted once a catheter has been inserted into the patient's vasculature. The retraction of the needle hub can be triggered by the sliding of the slider. The slider may also function to guard the distal tip of the needle once the needle hub is retracted within the barrel.

Abstract: A syringe pump can be operated to produce fluid flow from a syringe installed therein. Features of the pump can produce a desired rapid commencement of flow followed by smooth delivery uninterrupted by stiction-induced slowing and acceleration. A stiff drivetrain can facilitate detection of excessive forces indicative of friction at a stopper-wall interface. The motor drive, gearing, and control parameters can enable customized acceleration patterns to determine optimal initial stage advancement to provide fluid delivery. These patterns can minimize or eliminate the delay in commencement of flow by overcoming both mechanical slack remaining and syringe stopper slack. To avoid flow irregularities produced by stiction forces in the stopper further, a mechanical vibration can be provided to the syringe and/or barrel to introduce movement of the stopper-wall interface, reducing the creation of high static friction coefficients.

Abstract: In some embodiments a system and method are described for safeguarding a hazard. The hazard, for example a needle point, may be moved between a protected retracted position, an active extended position and/or an intermediate position. Optionally in the retracted position, the hazard may be protected inside a housing. Optionally in the extended position, the hazard may be exposed. Optionally, in the intermediate position the hazard may be partially protected and/or concealed, for example by a shield and/or in an indentation. In some embodiments, compromising a shield causes the hazard to be retracted to the retracted position.

Abstract: A steerable endoscope system includes a continuum manipulator, a plurality of syringes, and a steerable tip. The continuum manipulator includes a plurality of spaced discs and a plurality of backbones each extending through all discs. A bending movement of the continuum manipulator changes a varying linear displacement of each backbone. Each backbone is further coupled to a different one of the syringes such that the linear displacement of each backbone pushes or pulls a piston of the corresponding syringe by a varying amount. The steerable tip includes a plurality of bellows each pneumatically coupled to a different syringe such that movement of the piston of a syringe causes the corresponding bellow to inflate or deflate. Because the distal end of each bellow is fixedly coupled to the same end effector, variations in the amount of inflation or deflation on each bellow causes a bending of the steerable tip.
