Abstract
A guidewire system includes an elongated wire configured for insertion into a luminal space, such as the vasculature, of a body. The wire is conductive and configured to conduct electrical signals. One or more sensors are coupled to a distal section of the wire and configured to send and receive the electrical signals via the wire. The wire through which the one or more sensors are coupled is the only wire through which the one or more sensors send and receive the electrical signals.
Claims14
A method of using a medical device the method comprising:
- positioning at least one sensor coupled to a first elongated member within a luminal space of a body, wherein the at least one sensor comprises a pressure sensor;
- positioning a second elongated member adjacent a portion of the first elongated member;
- translating the second elongated member relative to the at least one sensor;
- sensing pressure, using the at least one sensor, during translation of the second elongated member relative to the at least one sensor;
- detecting, with the at least one sensor, a change in pressure indicative of a change in position of the second elongated member relative to the at least one sensor;
- and
- transmitting a data signal from the at least one sensor responsive to the second elongate member being translated, the data signal being indicative of the relative location of the second elongated member with respect to the at least one sensor.
A method of deploying a device within a body, the method comprising:
- positioning at least one sensor coupled to a guidewire within a luminal space of a body wherein the at least one sensor comprises a pressure sensor;
- positioning an implantable device carried by a catheter within the luminal space;
- translating the catheter and the implantable device relative to the at least one sensor within the luminal space;
- sensing pressure, using the at least one sensor, during translation of the catheter and implantable device relative to the at least one sensor;
- detecting, with the at least one sensor, a change in pressure indicative of a change in position of the catheter;
- transmitting a data signal from the at least one sensor responsive to the catheter and the implantable device being translated, the data signal being indicative of the relative location of the catheter with respect to the at least one sensor;
- and
- positioning the implantable device at a desired location based on the data signal from the at least one sensor.
