Devices, Systems and Methods for Treating Disorders of the Ear, Nose and Throat
First Claim
1. An over-the-wire biopsy device comprising:
- an elongate shaft having a lumen and a distal end;
specimen capturing jaws on the distal end of the shaft, said jaws being moveable between an open position and a closed position, said jaws, when is said closed position, having an opening formed therein, said opening being sized to permit passage of a guidewire therethrough and positioned in alignment with said lumen such that the device may be advanced over a guidewire while the jaws are in the closed position.

Abstract
Sinusitis, mucocysts, tumors, infections, hearing disorders, choanal atresia, fractures and other disorders of the paranasal sinuses, Eustachian tubes, Lachrymal ducts and other ear, nose, throat and mouth structures are diagnosed and/or treated using minimally invasive approaches and, in many cases, flexible catheters as opposed to instruments having rigid shafts. Various diagnostic procedures and devices are used to perform imaging studies, mucus flow studies, air/gas flow studies, anatomic dimension studies and endoscopic studies. Access and occluding devices may be used to facilitate insertion of working devices such asendoscopes, wires, probes, needles, catheters, balloon catheters, dilation catheters, dilators, balloons, tissue cutting or remodeling devices, suction or irrigation devices, imaging devices, sizing devices, biopsy devices, image-guided devices containing sensors or transmitters, electrosurgical devices, energy emitting devices, devices for injecting diagnostic or therapeutic agents, devices for implanting devices such as stents, substance eluting or delivering devices and implants, etc.
