Abstract: A self cleaning inlet head for use on a shunt. The head has a tube with openings disposed in predetermined positions in its wall, and a cleaning element installed inside the tube. The cleaning element may comprise a central shaft with a number of bristles protruding therefrom, preferably in locations substantially identical to the positions of the openings in the wall of the tube. Mutual vibratory motion between the cleaning element and the tube causes at least some of the bristles to enter the openings, thereby keeping them clear, and preventing tissue growth into them. The vibratory motion may be generated by the action of an external field on a responsive part of the cleaning element, such as an external magnetic field operating on a magnetic or magnetized part of the cleaning element or the bristles. Alternatively, the external field may be an ultrasound field operating on the bristles.

Abstract: Disclosed is a self-cleaning catheter system for fluid passage including a catheter, configured to be implanted in a body cavity of a subject and including at least one aperture fluidly coupling the catheter to the outside thereof, a cleaning unit configured for motion in the catheter such as to at least one of mechanically prevent, remove and mitigate occlusion in the at least one aperture, and an implantable controller. The cleaning unit is functionally associated with the controller, which is configured to (i) receive at least one signal indicative of a state of occlusion in the catheter, and (ii) provide an indication of the state of occlusion at least if the at least one signal indicates a blockage in the catheter and/or (iii) activate the cleaning unit if the at least one signal indicates a blockage of the catheter.

Abstract: Disclosed is s self-cleaning catheter system with self-monitoring capabilities. The catheter system includes a catheter configured to be implanted in a body cavity of a subject, a cleaning unit configured for motion within the catheter such as to mechanically prevent and/or remove or mitigate blockage of at least a section of the catheter, an implantable sensor, and an implantable controller functionally associated with the cleaning unit and configured for activation thereof. The implantable sensor is communicatively associated with the implantable controller and is configured to detect motion of the cleaning unit, and to output one or more signals indicative of the motion of the cleaning unit. The implantable controller is configured to receive the one or more signals from the implantable sensor and, based, at least, thereon, to provide at least one motion indication, at least when the one or more signals are indicative of malfunctioning of the cleaning unit.

Abstract: Disclosed is an implantable catheter for fluid passage, including a catheter tube, a catheter tip member including one or more apertures and an open proximal end, and a cleaning unit at least partially positioned within the catheter tip member. The catheter tip member is connected at the proximal end thereof to the catheter tube, thereby fluidly coupling the catheter tube to an exterior of the catheter. The cleaning unit is configured for movement within the catheter tip member such as to mechanically prevent, mitigate, and/or remove blockage in the one or more apertures when the catheter tip member is implanted in a body cavity. The catheter tip member further includes a stopper configured to be engaged by a tip portion of a mandrel, such as to prevent the mandrel from reaching and/or damaging the cleaning unit when using the mandrel to guide the catheter tip member into the body cavity.

Abstract: Briefly, in one example of the present invention, a code generator automatically produces Viterbi algorithm code for the architecture of a general-purpose processor. Upon input of version parameters such as, but not limited to, the generator polynomials, the constraint length and the rate, the code generator produces versions of Viterbi algorithm code for use in the processor. In another example, a code generator produces a description of a Viterbi accelerator. The processor may be a digital signal processor.
