Abstract: Infusion pumps and associated methods for delivering medicament to a user during error conditions. An infusion pump can include a sensor, a pumping mechanism to deliver medicament through an infusion set to the user, and a processor operably coupled to the sensor and the pumping mechanism. The processor can be configured to receive an indication from the sensor of an error condition, and continue operating the pumping mechanism to deliver a predetermined quantity of medicament without correcting the error condition. The predetermined quantity can be based at least in part on a characteristic of the infusion set.

Abstract: A safety intravenous catheter that includes a passive release feature. The catheter assembly includes ready, safe, and released positions. In the release position, a retainer being in a proximal retainer position relative to a collar enables release of the catheter hub from the catheter insertion device. The sharp tip of the insertion needle remains inaccessible in the release position in order to prevent unwanted needle sticks.

Abstract: An echogenic needle may have at least one V-shaped spiral groove formed at its distal portion adjacent to its patient end. The walls of the groove are orthogonal to each other. The groove is titled at a given angle from a neutral position toward the proximal end of the needle so that when the needle is inserted into the patient at an insertion angle under ultrasound imaging, the ultrasound wave emitted from the ultrasound transducer is reflected in a substantially reverse direction back to the transducer by at least one wall of the spiral groove. A pair of crisscrossing grooves may be spirally wound about the distal portion of the needle with each groove being tilted to the given angle to enhance echogeneity. The echogeneity of the needle may also be enhanced by increasing the pitch density of each groove while maintaining the crisscrossing groves at their neutral position.

Abstract: An LVP that provides peristaltic pumping to removably couplable administration set tubing assemblies supplying medical infusate. The LVP includes a housing, a drive-train assembly, and a controller. The housing includes an assembly receptacle configured to receive an administration set tubing assembly. The drive-train assembly provides mechanical peristaltic movement within the assembly receptacle. The drive-train assembly includes a stepper motor located within the housing and a camshaft assembly, driven by the stepper motor and at least partially extending into the assembly receptacle. The camshaft assembly includes a unitary camshaft and a plurality of tube engaging members that cooperatively move according to rotation of the unitary camshaft. Further, the controller is located within the housing that controls operation of the stepper motor and the camshaft assembly.

Abstract: An infusion pump, including a housing, a user interface, a motor and a set of drive components, and a controller. The housing enables selective stacked attachment with other infusion pumps. The housing includes a top portion with a handle integrated into an outer surface that partially defines a generally U-shaped retaining feature. The housing also includes a bottom portion with a generally U-shaped projection that is contoured to selectively mate with the retaining feature of another infusion pump. The user interface provides a front side to the housing that receives commands regarding infusion pump operation. The motor and set of drive components are at least partially located within the housing and mechanically direct infusion of infusate. The controller is located within the housing and that controls operation of the motor and the set of drive components.

Abstract: A method of creating a feature on a needle. The method comprising the steps of providing a needle having a sharpened distal end for insertion into an insertion site on a subject, a proximal end, and a tubular wall defining an inner diameter and an outer diameter; gripping a distal portion of the needle about the outer diameter; gripping a proximal portion of the needle about an outer diameter; and applying a compressive force between the distal portion and the proximal portion sufficient to effect an outward buckling of the tubular wall, thereby increasing an outer diameter of the tubular wall between the distal portion and the proximal portion.

Abstract: A splittable sheath includes a splittable sheath body, a splittable sheath hub, and a valve element. The sheath body comprises a generally flexible tubular structure, a proximal end, and a distal end. The sheath body defines a longitudinal axis and is splittable into two halves along a pre-determined line generally parallel to the longitudinal axis. The sheath hub extends from the proximal end of the sheath body and defines a longitudinal axis generally aligned with the longitudinal axis of the sheath body. The sheath body and sheath hub form an inner cavity along their respective longitudinal axes. The valve element includes a resilient plate and a sealing element. The resilient plate includes a distal portion extending radially inwardly from a side of the inner cavity. The sealing element includes a sealing surface and is supported by the resilient plate such that the sealing element is biased toward a position against a second sealing surface on at least one of the splittable sheath body and hub to substantially seal the inner cavity.

Abstract: A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.
