Abstract: A surgical fixation device is provided, including a preformed cranial mesh configured to generally conform to a predetermined averaged geometry. The cranial mesh includes a preformed flexible mesh body having opposed inner and outer surfaces, and a plurality of apertures that extend through the mesh body from the outer surface to the inner surface, each of the plurality of apertures extending along a respective central axis from the outer surface to the inner surface. The mesh body is configured as-manufactured to contact the predetermined averaged geometry at least at three spaced apart locations, such that 1) no portion of the mesh body crosses the predetermined averaged geometry in a first direction from the outer surface toward the inner surface, and 2) no location on the inner surface of the mesh body is spaced from the predetermined averaged geometry a distance greater than a select distance along the first direction.

Abstract: An ultrasonic probe for flow rate measurement is disclosed having a plurality of transducers mounted on a flexible cable configured to be inserted in a body cavity to obtain cardiac or other biometric telemetry. The flexible cable is provided with a disposable body which covers and microbially isolates the flexible cable and transducers. The disposable body is flexible and permits rotation of the flexible cable within it. Removal and replacement of the disposable body allows the probe to be used again without sterilization of the probe itself. A sensor window may be provided in the disposable body to allow transmission of ultrasonic signals, said window being provided with an anechoic surface treatment to reduce reception spurious ultrasonic echoes due to the material of the sensor window.
