Abstract: An intravenous catheter device can include a safety mechanism having a slider that couples to a catheter adapter and slides relative to a barrel. 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.

Abstract: IV filters are described herein. An IV filter includes a body, a filter media, and a bulb. The body defines a body volume. The filter media is disposed within the body volume. The filter media defines an inlet portion of the body volume and an outlet portion of the body volume. The filter media permits inlet flow from the inlet portion of the body volume to the outlet portion of the body volume and captures particulate from the inlet flow. The bulb defines a bulb volume in fluid communication with the outlet portion of the body volume. The bulb is deformable to compress the bulb volume and direct back flow from the outlet portion of the body volume through the filter media and into the inlet portion of the body volume, displacing particulate captured in the filter media into the inlet portion of the body volume.

Abstract: A medication delivery device (MDD) (e.g., injection pen, wearable pump) is paired with an external device (e.g., smart phone, iPad, computer) via wireless link or wireline connection. The MDD provides to the external device captured data from the flow sensor relating to medicine delivery to a patient to ensure complete delivery and minimize MDD misuse or malfunction or inaccuracies in dosing. The MDD can have Bluetooth™ and/or near field communication (NFC) communication circuits for proximity-based pairing and connectivity with the external device for real-time or deferred transfer of captured data to the external device, depending on memory and power availability at the MDD. The MDD or external device can use captured data and corresponding time stamps to determine flow infomatics such as flow rate, total dose delivered, and dose completion status. An LED on the MDD indicates states such as powered on, paired, delivery in progress and delivery completion.

Abstract: A closure assembly for a medical device, preferably in the form of a tamper evident closure, having an outer sleeve including an open end and a closed end. A tip cap includes a flow restrictor disposed within the sleeve in accessible relation by the medical device through the open end.

The indicator member is captured within said hollow interior upon removal of said tip cap from the sleeve through the open end. An end cap may be attached to the sleeve, to define a closed end thereof, by a snap-fit connection similar to, but distinguishable from, the snap-fit connection between the retainer member and the interior of the sleeve.

Abstract: A balloon catheter by which a drug can be effectively delivered to living body tissue and a method of manufacturing the balloon catheter, and a treatment method. The balloon catheter is provided on an outer surface of a balloon with a plurality of elongate bodies which are independent crystals of a water-insoluble drug that extend in an elongate form. The elongate bodies have long axes extending in directions along the outer surface of the balloon when the balloon is in a deflated state. Deformation, when the balloon is inflated from the deflated state, of portions on an outer surface side of the balloon to which end portions of the elongate bodies are fixed causes a force to act on the elongate bodies such that the long axes of the elongate bodies approach perpendicularity to the outer surface of the balloon.

A first engagement member is arranged at the plunger rod, such that a longitudinal movement of the plunger rod yields a rotational movement of said first engagement member. The first engagement member includes a grooved surface. A second engagement member is arranged at the barrel to engage with said grooved surface of the first engagement member, wherein the first engagement member is arranged to move relative to the second engagement member, such that feedback is given to a user as the plunger rod is moved relative to the barrel for driving said plunger. The first engagement member is arranged at said plunger rod with a predetermined play there between.

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.
