Abstract
A locator as part of a toolkit for locating an implanted valve. The locator is used in concert with an indicator that nests therein. The locator has a lower ring with a contact surface, contacting a patient, a key positioning the nested indicator to prevent rotation, and a lower ring joint opposite the contact surface. Also included is an upper ring with an upper ring joint rotatingly interfacing with the lower ring joint, a flow direction identifier, and a flow setting identifier. Further, the upper and the lower rings rotate relative to each other, and the lower ring is floor-less.
Claims20
A locator for use with a toolkit for locating an implanted valve and configured for use in concert with an indicator that nests therein, the locator comprising:
- a lower ring, comprising:
- a contact surface configured for contacting a patient;
- a key extended inwardly radially from an inner nesting indicator surface, the key being configured to align with key points of the nested indicator to prevent rotation;
- and
- a lower ring joint opposite the contact surface;
- and
- an upper ring, comprising:
- an upper ring joint rotatingly interfacing with the lower ring joint;
- a flow direction identifier opposite the upper ring joint and comprising a visual indicator of flow direction that is identifiable through the implanted valve;
- and
- a flow setting identifier opposite the upper ring joint and denoting settings of the implanted valve;
- wherein the upper and the lower rings rotate relative to each other, and
- wherein the lower ring is floor-less.
A method of using a toolkit for locating an implanted valve, the toolkit comprising a locator, comprising:
- an upper and a lower ring rotatably engaged to each other, wherein the upper ring comprises:
- an upper ring joint rotatably engaged with a lower ring joint that is opposite a contact surface of the lower ring;
- and
- a flow direction identifier opposite the upper ring joint and comprising a visual indicator of flow direction that is identifiable through the implanted valve,
- a flow setting identifier opposite the upper ring joint and denoting settings of the implanted valve;
- and
- an indicator and an adjustor that nest within the locator,
- the method comprising the steps of:
- placing the locator generally over the implanted valve;
- nesting the indicator in the locator;
- centering the locator and the indicator over the implanted valve;
- determining a flow direction, based on the flow direction identifier, and a valve setting based on the flow setting identifier, of the implanted valve;
- and
- rotating the upper ring of the locator to match the determined flow direction and valve setting while maintaining a position of the lower ring.
A locator for use with a toolkit for locating an implanted valve and configured for use in concert with an indicator that nests therein, the locator comprising:
- a lower ring, comprising:
- a contact surface configured for contacting a patient;
- a key extended from an inner nesting indicator surface, the key being configured to align with key points of the nested indicator to prevent rotation;
- and
- a lower ring joint opposite the contact surface;
- and
- an upper ring, comprising:
- an upper ring joint rotatingly interfacing with the lower ring joint;
- a flow direction identifier opposite the upper ring joint and comprising a visual indicator of flow direction that is identifiable through the implanted valve;
- and
- a flow setting identifier opposite the upper ring joint and denoting settings of the implanted valve;
- wherein the upper ring rotates relative the lower ring that is fixed.
