Abstract

A scope system includes a processor and a scope device. The scope device includes a handle configured to remain outside of the body and an elongated shaft extending from the handle to a distal tip and including a working channel extending therethrough. The working channel is open at the distal tip of the shaft. The shaft is inserted through a bodily lumen to a target surgical site. The shaft includes at least one sensor transmitting to the processor sensor data relating to the target surgical site.

First claim

What is claimed is:

1. A scope device, comprising:
a handle configured to remain outside of a body;
a shaft extending from the handle to a distal tip of the shaft and including a working channel extending therethrough, wherein the distal tip includes a camera and a light source, the working channel being open at the distal tip and adjacent to the camera and the light source, the shaft being configured to be inserted through a bodily lumen to a target site; and
a pressure sensor within the distal tip of the shaft and disposed in a housing, the pressure sensor being configured to measure intraluminal pressure relating to the target site and to transmit sensor data relating to the target site, an active portion of the pressure sensor being adjacent to a port configured to permit a fluid to exert a pressure on the active portion, wherein the active portion is radially inward of the port and proximate an outer surface of the shaft, and wherein the active portion is water-tight so that the active portion of the pressure sensor is separated from the fluid while permitting the active portion of the pressure sensor to measure the pressure of the fluid.

2. The scope device of claim 1 , wherein the pressure sensor is a chip pressure sensor.

3. The scope device of claim 1 , wherein the active portion is covered by a water-tight coating.

4. The scope device of claim 3 , wherein the water-tight coating protects a lead extending from the pressure sensor.

5. The scope device of claim 1 , wherein the housing is rectangular.

6. The scope device of claim 1 , further comprising a connector for coupling to a fluid source.

7. The scope device of claim 1 , wherein the pressure sensor is configured to transmit the sensor data to a processor.

8. The scope device of claim 7 , wherein the pressure sensor is configured to provide the sensor data to the processor by a lead coupled to the pressure sensor.

9. A scope device, comprising:
a handle configured to remain outside of a body;
a shaft extending from the handle to a distal tip of the shaft and including a working channel extending therethrough, the working channel being open at the distal tip, the shaft being configured to be inserted through a bodily lumen to a target site; and
one or more sensors configured to transmit sensor data, wherein the one or more sensors includes a pressure sensor within a housing in the distal tip, an active portion of the pressure sensor being adjacent to a port configured to permit a fluid to exert pressure on the active portion, wherein the active portion is radially inward of the port and radially inward of an outer surface of the shaft, and wherein the active portion is water-tight so that the active portion of the pressure sensor is separated from the fluid while permitting the active portion of the pressure sensor to measure the pressure of the fluid.

10. The scope device of claim 9 , wherein the active portion of the pressure sensor is covered by a water-tight coating.

11. The scope device of claim 10 , wherein the water-tight coating protects a lead extending from the pressure sensor.

12. The scope device of claim 9 , wherein the one or more sensors sense temperature.

13. The scope device of claim 12 , wherein the one or more sensors include the pressure sensor and a temperature sensor to sense temperature.

14. The scope device of claim 9 , wherein a first sensor of the one or more sensors is the pressure sensor, and wherein a second sensor of the one or more sensors is one of a temperature sensor, a pH sensor, a capacitive sensor, or a gyroscope sensor.

15. The scope device of claim 9 , further comprising a connector configured to couple to a fluid source.

16. The scope device of claim 9 , wherein the one or more sensors are configured to transmit the sensor data to a processor.

17. The scope device of claim 9 , wherein the pressure sensor is coupled to a lead that extends through the shaft.
