A catheter system includes an elongated tube structure configured for insertion into a luminal space, such as the vasculature, of a body. The catheter is conductive and configured to conduct electrical signals. The catheter includes one or more power and data coupling devices configured to send and receive power and/or data signals, such as from an underlying guidewire disposed within a lumen of the catheter. One or more sensors are coupled to a distal section of the catheter and are electrically connected to the one or more power and data coupling devices.

Catheter for imaging and measurement of pressure and other physiological parameters

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.

Guidewire for imaging and measurement of pressure and other physiological parameters

A power and data coupling device for medical sensors comprises a first conductive surface integrated into a medical device and configured to couple via an electric field with a second conductive surface. The second conductive surface is translatable with respect to the first conductive surface. Additionally, the first conductive surface is connected to a power source for providing power, through the electric field, to the second conductive surface. The first conductive surface also radiates a time-varying electric field that is configured to convey power to the second conductive surface. Further, the first conductive surface is connected to a pick-up that is configured to receive signals from the second conductive surface.

Guidewire for imaging and measurement of pressure and other physiologic parameters

Catheter for imaging and measurement of pressure and other physiologic parameters

A medical device system for concurrent power and data transfer comprises an elongated conductive member. At least a portion of the elongated conductive member is configured for insertion within an intraluminal space. One or more sensors that are in electrical connection with the elongated conductive member. The medical device system uniquely allocates each of the plurality of unique contiguous segments within a signal space to one of (i) one or more power channels or (ii) one or more signal channels. The medical device system then sends the electrical signals, via the elongated conductive member, to one or more sensors that are in electrical connection with the elongated conductive member. The medical device harvests energy from the electrical signals. The medical device system isolates transmitted data signals within at least one of the one or more signal channels the data signals generated by the one or more sensors.
