Endoscopic device
First Claim
1. An endoscopic device for use at a site within a body, the endoscopic device comprising:
- an inner portion defining;
an operative channel providing a path for fluid to or from the body site; and
an optical channel; and
a sheath surrounding the inner portion to define a pressure-sensing channel and a fluid channel providing a path for fluid to or from the body site, the pressure-sensing channel and the fluid channel being defined between the sheath and the inner portion, wherein the pressure-sensing channel is configured to communicate with a pressure sensor.

Abstract
An endoscopic device for use at a site within a body includes an inner portion and a sheath surrounding the inner portion. The inner portion defines an operative channel and an optical channel. The operative channel provides a path for fluid to or from the body site. The sheath defines a pressure-sensing channel and a fluid channel that provides a path for fluid to or from the body site. The pressure-sensing channel and the fluid channel are defined between the sheath and the inner portion. The pressure-sensing channel is configured to couple to a pressure sensor to sense pressure at the body site.

27. A method of performing a surgical procedure at a body site, the method comprising:
-
connecting a fluid supply to an endoscopic device that defines a pressure-sensing channel between a sheath and an inner portion, a fluid flow path between the sheath and the inner portion, and a fluid flow path within the inner portion;
coupling a pressure sensor to the pressure-sensing channel;
inserting the endoscopic device into the body site;
inserting an operative device into an operative channel defined by the inner portion;
connecting a light source to an optical channel defined by the inner portion and housing an optical device;
irrigating fluid from the fluid supply to the body site through one of the fluid flow paths;
removing fluid from the body site through the other of the fluid flow paths; and
monitoring pressure that is sensed at the pressure sensor.

29. An endoscopic device for use at a site within a body, the endoscopic device comprising:
-
an inner portion defining an operative channel enclosed within the inner portion and providing a path for fluid to and from the body site, the operative channel being configured to receive the operative device;
a sheath surrounding the inner portion to define a pressure-sensing channel and a fluid channel providing a path for fluid to or from the body site, the pressure-sensing channel and the fluid channel being defined between the sheath and the inner portion, the pressure-sensing channel being configured to communicate with a pressure sensor; and
a pressure-sensing port that maintains coupling between the pressure sensor and the pressure-sensing channel as the pressure-sensing port is rotated relative to the sheath and about a longitudinal axis of the sheath.

30. An endoscopic device for use at a site within a body, the endoscopic device comprising:
-
an inner portion defining an operative channel enclosed within the inner portion and providing a path for fluid to or from the body site, the inner portion including an alignment element; and
a sheath surrounding the inner portion to define a pressure-sensing channel and a fluid channel providing a path for fluid to or from the body site, the pressure-sensing channel and the fluid channel being defined between the sheath and the inner portion, the sheath including an alignment element that aligns with the alignment element of the inner portion;
wherein the pressure-sensing channel is configured to communicate with a pressure sensor.
