DILATING CATHETER EQUIPPED WITH NAVIGATION SENSOR AND VENTILATION PATH AT TIP

摘要

To provide a dilating catheter.SOLUTION: A dilating catheter includes a catheter shaft, an expandable element, and a navigation sensor. The catheter shaft includes a proximal shaft part for defining a proximal shaft end part, a distal shaft part for defining a distal shaft end part, and an operation lumen extending between the proximal shaft end part and the distal shaft end part. The expandable element is disposed on a proximal distal shaft part of the distal shaft end part, and is configured to be expanded so as to dilate an anatomical passage of a patient. The navigation sensor is arranged in the distal shaft part, and is configured so as to generate a signal corresponding to a position of the distal shaft part in the patient. In various examples, the dilating catheter may further include a spherical distal tip part, and the navigation sensor may be arranged in the spherical distal tip part.SELECTED DRAWING: Figure 5A
