Abstract: A catheter assembly or other elongate tubular device for use in establishing vascular or other access within the body of a patient is disclosed. The catheter assembly is equipped with one or more sensors that enable monitoring of one or more physiological aspects of the patient or physical aspect of the catheter assembly itself when the catheter assembly is disposed within the patient. Such aspects include central venous pressure, body temperature, ECG heart signals, oxygen levels, ultrasound data, glucose, etc. The catheter assembly includes the ability to wirelessly transmit or otherwise forward data relating to the detected physiological parameters to another location, such as a patient electronic medical record, smartphone or other mobile device, nurse station, etc. Catheter assemblies configured to detect the frequency of catheter flushing, flushing quality, etc., are also disclosed.

Abstract: A venous catheter assembly includes a hub with opposing suture wings, an extension leg coupled to the hub, and an elongate catheter tube designed for insertion into a blood vessel of a patient. The elongate catheter tube is coupled to the hub and includes at least one fluid-carrying lumen within the outer wall extending between a proximal end and a distal end of the elongate catheter tube. The fluid-carrying lumen is in fluid communication with the extension leg and an opening in the outer wall at the distal end of the elongate catheter tube. The elongate catheter tube also includes at least one terminating lumen within the outer wall extending to a closed termination point.

Abstract: A catheter assembly including an elongate catheter tube is disclosed. The number of lumens defined by the catheter tube can vary as a function of longitudinal length along the catheter tube. For instance, the catheter tube can define three lumens from the proximal end of the catheter tube and terminate one of the lumens at an intermediate termination point such that only two lumens are defined further distally along the catheter tube. A sensor can be placed in the terminating lumen so as to isolate it from the other lumens and from blood or other body fluids while still enabling the sensor to reside within the patient body when the catheter tube is positioned in the patient for use. In addition to this, various other lumen transition and sensor configurations are disclosed.

Abstract: An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing and a mounting structure. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by placement in the mounting structure. However, unless force is applied to keep the occluder mechanism in the mounting structure, the occluder will move relative to the mounting structure and return to the first, closed position.

Abstract: A sensor and method of use provides for detection of an occlusion (or sudden pressure increase) in tubing during the administration of solutions to a patient. The occlusion sensor may be attached to an infusion pump using a biasing mechanism. The tubing may be positioned in contact with the occlusion sensor using a cassette. Detection of an occlusion in the tubing is accomplished by measuring the compression and expansion of the tubing. When the tubing becomes occluded pressure within the tube will increase, resulting in expansion of the tubing. Expansion of the tubing exerts a force on the sensor to trigger an alarm to alert medical personnel of the occluded tube.

Abstract: Current phacoemulsification handpieces require rigorous cleaning after each procedure because the aspiration and irrigation pathways for fluids are integral to the handpiece. According to the present invention, a removable horn extension and nosecone may be used with a phacoemulsification handpiece to allow for disposable fluid pathways exterior to the handpiece. This will reduce the cleaning time and effort, reduce cross-contamination, and increase the lifespan of the handpiece. Furthermore, the current invention allows different horn extensions to be used to excite different motions at the tip of the handpiece, depending on the preference of the surgeon.

Abstract: A Langevin transducer horn uses split electroding or selective electroding of transducer elements and phase relationships of the voltages applied thereto to determine the relative longitudinal and flexural/transverse motion induced in the tip of the horn.
