Abstract

Sinusitis, enlarged nasal turbinates, tumors, infections, hearing disorders, allergic conditions, facial fractures and other disorders of the ear, nose and throat 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, endoscopic studies and transillumination studies. Access and occluder devices may be used to establish fluid tight seals in the anterior or posterior nasal cavities/nasopharynx and to facilitate insertion of working devices (e.g., scopes, guidewires, catheters, tissue cutting or remodeling devices, electrosurgical devices, energy emitting devices, devices for injecting diagnostic or therapeutic agents, devices for implanting devices such as stents, substance eluting devices, substance delivery implants, etc.

Claims

1. An anterior/posterior occlusion and access device for use in the diagnosis and/or treatment of sinusitis or a disorder of the ear, nose or throat, said device comprising:

a tube having an anterior end, a posterior end and at least one lumen;

an anterior occluder at a first location on the tube;

a posterior occluder at a second location on the tube, said second location being posterior to said first location;

a working device insertion opening located anterior to the anterior occluder; and

a working device exit opening located between the anterior occluder and the posterior occluder; and

at least one additional element selected from the group consisting of a) a valve that is operative to allow a working device to be inserted through said device insertion port while preventing blood or other fluid from backflowing out of the device insertion port at least when no working device is inserted therethrough, b) at least one moveable suction port for suctioning blood, fluid or debris from a plurality of locations between the anterior occluder and posterior occluder and/or c) separate infusion and suction lumens such that fluid may be infused into a location between the anterior and posterior occluders at the same time that fluid is being suctioned from a location between the anterior and posterior occluders;

said nasal access and occlusion device being deployable such that i) the anterior occluder occludes the nostril or nasal cavity on one side of the intranasal septum ii) the posterior occluder occludes the nasopharynx at a location posterior to the intranasal septum and iii) a working device may be inserted through the working device insertion opening and advanced out of the working device exit opening to a location within the nose, nasopharynx or paranasal sinus.

2. A device according to claim 1 wherein the anterior occluder comprises a balloon.

3. A device according to claim 1 wherein the posterior occluder comprises a balloon.

4. A device according to claim 1 which includes at least first and second working device exit openings such that a working device may be selectively advanced out of either the first or second working device exit opening.

5. A system that comprises a nasal access and occlusion device according to claim 1 in combination with at least one working device selected from the group consisting of:

a guidewire;

a guide catheter;

a guide catheter shaped to advance into the ostium of a paranasal sinus;

a balloon catheter,

apparatus for delivery of a stent;

apparatus for delivery of a substance-eluting stent;

implantable apparatus for exerting pressure on bone or soft tissue to cause reshaping of the bone or soft tissue;

apparatus for cutting tissue;

apparatus for ablating tissue;

apparatus for debulking tissue;

apparatus for cauterizing tissue;

apparatus for dilating a passageway;

apparatus for delivering a cryogen;

apparatus for delivering a radiographic contrast agent,

apparatus for delivering a diagnostic or therapeutic substance;

a cannula;

an endoscope;

a sensor;

a light;

a diagnostic device;

a therapeutic device.

6. A device according to claim 1 further comprising at least one suction port located on the tube between the anterior occluder and the posterior occluder such that fluid or debris may be aspirated though the aspiration port and through a lumen of the tube.

7. A system comprising a device according to claim 1 in combination with an anterior nasal occlusion and access device that is positionable on the other side of the nasal septum, said anterior nasal occlusion and access device comprising:

an anterior occluder for occluding the nostril or nasal cavity on one side of the nasal septum; and

a working device insertion opening through which a working device may be inserted and advanced past the anterior occluder to a location within the nose, nasopharynx or paranasal sinus.

8. A system according to claim 7 wherein the anterior occluder of the anterior nasal occlusion and access device comprises a balloon.

9. A device according to claim 1 further comprising a valve associated with the working device insertion opening, said valve being configured to prevent backflow out of the working device opening when no working device is inserted through said working device insertion opening.

10. A system according to claim 7 further comprising a valve associated with the working device insertion opening of the anterior nasal occlusion and access device that is positionable on the other side of the nasal septum, said valve being configured to prevent backflow out of the working device opening when no working device is inserted through said working device insertion opening.
