Abstract: A lid for a wet wipes dispenser includes a dispenser lid base section and reclosable cover to the dispenser lid base section. The dispenser lid base section includes an interior wall supporting an interior ridge defining a wet wipe opening. A keyhole squeegee is disposed in the interior ridge and extending into the wet wipe opening. The keyhole squeegee has angled walls which define an angled keyhole channel leading to an open side of a frusto conical section. The angled walls and the frusto conical section extend outward from the interior ridge. The wet wipes dispenser also includes a reclosable cover. A method of drawing a wet wipe from a wet wipe dispenser is also described.

Abstract: A transcutaneous energy transfer system with subcutaneous non coupled coils is used to transmit power and signals to an implanted biological support device or sensor, such as a flow sensor for measuring relatively low flow rates, such as hydrocephalic shunt flow. The flow sensor is configured to convert a shear wave generated by a transducer to a longitudinal wave at the interface of a signal pathway and the flow, wherein the longitudinal wave travels parallel to the flow and exits a flow channel to convert to a shear wave which intersects a second transducer. The transcutaneous energy transfer employs a pair of inductive coupling coils, wherein the coils are disposed in zero coupling orientation which can include a perpendicular orientation of corresponding coil axes.

Abstract: A probe system for measuring fluid flow in a conduit, such as a blood vessel with ultrasound transit time or similar measurement methods. The probe system having a probe body with a space to receive in a secure but detachable fashion a pliable soft insert. The insert has a central lumen or aperture which is sized to securely but detachably fit around a vessel or conduit without squeezing or in any way altering the conduit during application or use. The insert is acoustically matched with the vessel or conduit and fluid flowing therein to thereby minimize distortion or attenuation of ultra sound waves generated to assess flow. In a further aspect a set of inserts with varying sized lumens or apertures are provided to match with vessels or conduits of varying size. The system among other things increases accuracy of flow measurements while minimizing trauma to the vessel or conduit.
