The second body is of yielding material and at least partly covers the elongated element and extends beyond the second extremity of that element in such a way as to close off the opening thereof, such second body being overmoulded onto the first body and forming a single piece therewith.

Abstract: A catheter system may include a catheter adapter, a catheter extending distally from the catheter adapter, an introducer needle extending through the catheter, a flash chamber in fluid communication with a needle lumen of the introducer needle, and a seal element. The introducer needle may include a wall defining the needle lumen, a first notch formed through the wall, and a second notch formed through the wall. The seal element may be proximal to the first notch and the second notch and within the catheter between an outer surface of the introducer needle and an inner surface of the catheter. The seal element may prevent priming fluid from travelling distal to the seal element. The seal element in conjunction with the first notch, the second notch, and the flash chamber may facilitate pressure-driven blood flow into the catheter for detection of flashback and transfixing when priming occurs prior to insertion into vasculature.

Abstract: Apparatus and methods for error modeling and correction in one or both of (i) a partially or fully implanted or non-implanted medicant delivery mechanism (such as a pump), and (ii) implanted physiologic parameter sensor. In one exemplary embodiment, the apparatus and methods employ a training mode of operation, whereby the apparatus conducts “machine learning” to model one or more errors (e.g., unmodeled variable system errors) associated with the medicant dose calculation process, and (ii) generation of a medicant delivery operational model (based at least in part on data collected/received in the training mode), which is applied to correct or compensate for the errors during normal operation of the sensor and pump system. This enhances accuracy of medicant delivery, such as over the lifetime of an implanted pump at a single implantation site, or during multiple relocations of a transcutaneously implanted pump), and enables “personalization” of the pump to each user.

Abstract: A needling system, for use in areas where thin hollow needles are used to inject or aspirate fluids and gases, is provided and comprises a thin, rigid tube body needle that is open on both ends and throughout the length with one sharp end. The needle body and hub are designed such that the needle has a ball end that fits within a socket of the hub, forming a seal and allowing the needle to be oriented non-colinearly and non-parallel to the central axis of the hub. Needle orientation, relative to the hub, can be limited from a conical volume to a planar or multi planar angular orientations. The needle so configured allows the user to circumvent an obstacle that otherwise inhibits direct linear access to a point-of-interest by providing a device that can fit around or between obstructions providing optimal direct path towards the desired therapy delivery point.

Abstract: An injection device for subcutaneous delivery of fluid which comprises a puncture cannula and an indwelling cannula. In a starting position, a distal end region of the puncture cannula runs coaxially inside the indwelling cannula. The device comprises displaceably mounted first and second runners. The first runner is connected to the puncture cannula and the second runner to the indwelling cannula. A control element is movable over a predefined control area. The control element is configured such that, in a first part of the control area, the control element effects an equidirectional displacement of the first and the second runners, and hence fitting of the indwelling cannula and, in a second part of the control area, effects blocking of the second runner, and hence holding of the indwelling cannula in a dwell position, and return of the first runner and withdrawal of the puncture cannula into an end position.

Abstract: A device and method for measuring an IV pump infusion system flow comprises a fluid source configured to store medicinal fluid and a weight sensing mechanism comprising a weight sensor and microprocessor. The weight sensing mechanism is configured to detect the weight of the fluid source as the medicinal fluid leaves the fluid source. The device in the infusion system administers medicinal fluid using a set flow rate for the IV pump input into the control unit prior to infusion, measures the change in mass of the fluid source containing medicinal fluid as fluid exits the source, calculates the flow rate based on the change in mass over time, compares the calculations with a set flow rate, and adjusts the IV pump and flow rate based on the compared deviations, for improved delivery accuracy. This configuration may also prevent patient harm and medicine waste.
