发明名称 Transparent Endoscope Head Defining a Focal Length
摘要 A catheter configured for imaging objects substantially in focus is described herein. An imaging device is disposed on the distal end of the catheter. The imaging device has an effective focal plane that is located in front of the imaging device. The catheter also includes a transparent focal instrument that has an outer periphery that is positioned at the effective focal plane of the imaging device, to enable objects in contact with the outer periphery of the transparent focal instrument to be imaged substantially in focus.

主权项 1. A catheter configured for imaging objects substantially in focus, comprising: a) an imaging device disposed on a distal end of the catheter, the imaging device having an effective focal plane; b) a transparent focal instrument coupled to the catheter, the transparent focal instrument having an outer periphery that is positioned at the effective focal plane of the imaging device to enable objects in contact with the outer periphery of the transparent focal instrument to be imaged substantially in focus; and c) an open channel having a first orifice disposed about a side surface of the catheter in fluid communication with a second orifice on a distal end of the catheter.
