Abstract
Official abstract text for this publication.
This disclosure concerns devices and methods for measuring an amount of adjustment of an expandable implant using ultrasound. The implant may include an ultrasound counter including a vibration element tuned for ultrasonic vibration, the vibration element may be configured to produce an ultrasound vibration upon an adjustment of the expandable implant.
First claim
Opening claim text (preview).
What is claimed is: 1 . An expandable implant comprising: a plurality of vibration elements tuned for ultrasonic vibration, the vibration elements configured to produce the ultrasonic vibration upon an adjustment of the expandable implant; an agitation element including a plurality of bumps disposed on a shaft and configured to communicate with the vibration elements to produce the ultrasonic vibration upon the adjustment of the expandable implant. 2 . The expandable implant of claim 1 , further comprising the shaft, with the agitation element disposed on the shaft and configured to communicate with the vibration elements upon a rotation of the shaft. 3 . The implant of claim 1 , the agitation element comprising a rotatable permanent magnet. 4 . The implant of claim 3 , the rotatable permanent magnet further comprising the plurality of bumps configured to communicate with the vibration elements. 5 . The implant of claim 1 , further comprising an ultrasound transducer configured to count a total number of the ultrasonic vibrations produced by the vibration elements. 6 . The implant of claim 5 , wherein the vibration elements are positioned such that the total number of the ultrasonic vibrations produced by the vibration elements corresponds to an amount of change of a dimension of the implant. 7 . An implant comprising: a housing configured to be secured to a first portion of bone of a patient; a rod configured for telescopic engagement with the housing, the rod configured to be secured to a second portion of the bone of a patient; a plurality of vibration elements tuned for ultrasonic vibration; an agitation element comprising a shaft having a plurality of bumps configured to communicate with the vibration elements upon a rotation of the shaft; wherein the agitation element is configured to rotate as the rod moves relative to the housing; and wherein the rotation of the agitation element is configured to communicate with the vibration elements to produce the ultrasonic vibration. 8 . The implant of claim 7 , further comprising a piezoelectric transducer configured to count a total number of the ultrasonic vibrations produced by the vibration elements. 9 . The implant of claim 8 , wherein the vibration elements are positioned such that the total number of the ultrasonic vibrations produced by the vibration elements corresponds to a total amount of movement of the rod relative to the housing. 10 . The implant of claim 7 , the agitation element comprising a rotatable magnet. 11 . The implant of claim 10 , the rotatable magnet further comprising the plurality of bumps configured to communicate with the vibration elements. 12 . The implant of claim 7 , wherein a total of the number of ultrasonic vibrations corresponds to a change in length of the implant. 13 . The implant of claim 7 , wherein a total of the number of ultrasonic vibrations corresponds to a change in height of the implant. 14 . The implant of claim 7 , wherein a total of the number of ultrasonic vibrations corresponds to a change in width of the implant.
