Abstract: In an embodiment, the present invention provides an autoinjector that has one or more slip-resistant features. In certain embodiments, the exterior surface of the autoinjector housing forms at least one of indentures and protrusions that impart a slip-resistant texture to the housing of the autoinjector. In other embodiments, the one or more slip-resistant features are included on a label, which comprises a label substrate and is attached to the exterior surface of the housing of the autoinjector. The features are designed to improve the handling properties of the autoinjector and reduce the likelihood that the autoinjector will slip out of a user's or caregiver's hand during use.

Abstract: A sliding cover for a liquid delivery device, such as a cap (100) for a pen injector (200), incorporates a set of sensors including an optical sensor (110) with an output which changes during uncapping or capping motions on passing of a plunger (220) of the pen injector. This output is used together with a position sensor (120) to determine the position of the plunger along a cylinder (210) of the liquid delivery device. By monitoring changes in the plunger position, the quantity of dosages delivered by the liquid delivery device can be determined, displayed, stored and/or transmitted to an external device for further data processing or storage. Preferred implementations of the invention employ optical sensors with a converging beam (115), and/or position sensors employing linear potentiometer strips (132).

Abstract: A system of needles having rudders or keels is provided having perforations, such as kerfs, to allow the needles to be bent by the manipulations of wires imbedded within the needle body. The pulling or pushing of the embedded wires, or stylets, causes the needle tip to be bent, while within the body, to allow the needle to be steered past impediments towards the target necessitating treatment. Wires can be pulled or pushed and in some instances both a push and pull wire are provided to give the needle precision steerability. The needles are provided with a keel or rudder, or can be shaped such as with a teardrop cross-section, to give a degree of stabilization to the course the needle, and attendant tubing, takes within the patient. The kerf cut section of the needle, which can be on one side, two sides or all about the circumference of the needle, allows the needle to be bent one way and then, as needed, another way to allow the needle to be steered within the body.
