Abstract: A portable hand-held endoscopy system adapted for interchangeable use with a variety of endoscopes. The system includes an endoscope having a first end and a second end, the first end having an eyepiece and the second end having a viewing end, the endoscope further having a coupler for coupling to a light source; and a battery operated unitary digital camera having an optical input, viewing screen, digital signal processor, memory with embedded software for processing data from the processor and for displaying an image on the viewing screen, and a coupler having a first end and a second end, wherein the first end includes a connector for removably connecting to the eyepiece, and the second end is coupled to the optical input of the digital camera. The video display is rotatable and pivotable about several different axes of rotation and a pivot point spaced distally from the main camera body.

Abstract: An apparatus for creating an accessory maxillary ostium for purposes of ventilation, irrigation, or procedural work within the maxillary antrum. An introducer having a ventilation tube and grommet is provided to create and then provide access through the accessory maxillary ostium. An irrigation catheter may be advanced through the ventilation tube in order to irrigate or express the contents of the sinus cavities. A secondary irrigation catheter or a balloon catheter may be advanced through an outer irrigation catheter, deeply into the sinus cavity, in order to irrigate or express the contents of the sinus cavities. Moreover, the balloon catheter may alternatively or additionally be employed to for dilation of the natural ostium. Still further, a device for delivering drugs, fluids or the like, may be coupled to the ventilation tube for delivery of same.

Abstract: A medical imaging recording and viewing system adapted for use interchangably with a variety of endoscopes. The system includes a portable hand-held device that may be removably placed within a cradle affixed to the endoscope. An interface between an image acquisition device of the endoscope and the portable device permits images to be transmitted to and stored within the portable device. The portable device also may include a viewing screen to permit a user to view the images. A docking station may receive the portable device for transferring images to a separate viewing device and for recharging the battery of the portable device.
