Abstract: A flow control apparatus adapted to receive a feeding set includes a housing capable of receiving at least a portion of the feeding set. A pumping device is supported by the housing and positioned to contact the feeding set when the feeding set is received by the housing so the pumping device acts on the feeding set to produce fluid flow in the feeding set for delivery of fluid to a subject. An ultrasonic sensor is supported by the housing and arranged with respect to the pumping device to produce a sensor signal indicative of a viscosity of the fluid delivered through the feeding set. A control circuit is in communication with the ultrasonic sensor for receiving the sensor signal from the sensor indicative of the viscosity of the fluid and in communication with the pumping device to control operation thereof.

Abstract: An attachment arrangement has a housing and a needle located within the housing. The arrangement allows administration ports of different sizes to be inserted into and secured within the housing. In certain embodiments, compliant retainers secure the administration port within the housing. In certain other embodiments, the administration port is secured within the housing when the housing is compressed against the administration port by a housing compression element. Once the administration port is secured within the housing, a fluid-tight seal is formed between the attachment device and the administration port.

Abstract: Ultrasound catheter devices and methods provide enhanced disruption of blood vessel obstructions. Generally, an ultrasound catheter includes an elongate flexible catheter body with one or more lumens. An ultrasound transmission member or wire extends longitudinally through the catheter body lumen and, in many embodiments, a guide wire tube also extends through the same lumen. A distal head is fixed to or otherwise mechanically coupled with the distal end of the ultrasound transmission member or wire and is positioned adjacent the distal end of the catheter body. Although the distal end of the catheter body overlaps the distal head, the distal head is not directly affixed to the distal end of the catheter body. Thus, the distal tip may move freely, relative to the distal end of the catheter body when ultrasonic energy is applied through the ultrasound transmission member.

Abstract: An antimicrobial lubricant applied to an outer surface of an introducer needle as part of a catheter assembly device. The catheter assembly device further includes a septum having a slit through which the introducer needle is threaded. The antimicrobial lubricant is squeegeed, or removed from the outer surface of the introducer needle as the needle is removed from the slit following catheterization.
