Acclarent | Date: 2017-05-17

A guide catheter system for use in treating the sinus cavity or Eustachian tube is described. The system includes a guide catheter that has a proximal end and a distal end and an elongate shaft between the proximal end and the distal end and a guidewire. The guide catheter includes a deflection feature on a distal tip of the distal end for deflecting the guidewire at a predetermined angle.


An apparatus comprises a guidewire body and a light source. The guidewire body includes an optically transmissive element. The guidewire body is sized for insertion in a sinus ostium of a patient. The light source is in optical communication with the optically transmissive element of the guidewire body. The light source is operable to transmit infrared light or narrowband visible light through the optically transmissive element. A detector may be used to detect light transmitted by the optically transmissive element through the patient. The detector may include a camera or a photodetector. Glasses may be used to provide an overlay of a camera image or to filter out light to enable focusing on light of a specific wavelength. A beam processing element may be used to provide a beam waist with an average irradiance of more than 10 W/cm^(2 )within the acceptance angle of the optically transmissive element.

An inflator comprises a body, a first drive member, and a second drive member. The body defines a reservoir that is configured to hold fluid and includes an outlet. The first drive member is operable to move through the reservoir to drive fluid from the reservoir through the outlet. The second drive member is engaged with the first drive member. The second drive member is movable relative to the body through a first range of motion to actuate the first drive member to drive fluid through the outlet at a first rate. The second drive member is movable relative to the body through a second range of motion following the second range of motion. The first drive member is configured to either drive fluid through the outlet at a second rate or not drive fluid through the outlet as the second drive member moves through the second range of motion.

A method includes receiving image data, receiving surgical procedure data, and generating an operation plan. The image data is associated with anatomical structures in a nasal cavity of a patient. The image data and the surgical procedure data are received through a computing system. The act of generating an operation plan includes identifying a path for a surgical instrument in accordance with the image data and in accordance with the surgical procedure data. The act of generating the operation plan is performed through a computing system. The act of generating an operation plan further includes generating one or more instructional images depicting the identified path for the surgical instrument in a depiction of anatomical structures in the nasal cavity of the patient.


Apparatus for use in surgeries to treat disorders of the ear, nose, and throat including a hand-held device and rotating blade assembly. The apparatus may be connected to a vacuum source. A method of use is also disclosed.

Apparatus, including a guidewire having a distal end, that is configured to be inserted into proximity 5 with a nasal sinus of a patient, the guidewire having a lumen. The apparatus also includes an optic fiber, traversing the lumen, configured to illuminate the distal end, and a coil, wound around the optic fiber and located within the lumen at the distal end, configured to 10 generate a signal in response to a magnetic field interacting with the coil. A processor is configured to receive the signal and to evaluate a location of the distal end in response to the signal.


A medical device for the treatment and irrigation of a sinus opening is described. The device allows for single-handed operation to access, dilate and irrigate a sinus opening. The device includes a sinus guide catheter, a guiding element, a balloon dilation catheter, a balloon catheter movement mechanism and a guiding element movement mechanism. A method for treating a sinus opening and irrigating a sinus is also described.


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.


A medical device and method for the treatment of a sinus opening includes a handle, a guide catheter, a guide wire, a balloon catheter, a guide wire movement mechanism and a balloon catheter movement mechanism. The handle has proximal and distal ends and a longitudinal axis along the length of the handle. The guide catheter is attached to the distal end of the handle and has a catheter lumen. The guide wire and balloon catheter are both disposed at least partially in the handle and catheter lumen. The guide wire movement mechanism and the balloon catheter movement mechanism are both operatively disposed on the handle. In addition, the guide wire movement mechanism is configured for advancement and retraction of the guide wire through the handle and catheter lumen by user operation of the guide wire movement mechanism. Moreover, the guide wire movement mechanism includes an integrated guide wire locking and rotation mechanism configured for rotation of the guide wire and for securely locking and unlocking the guide wire to the guide wire movement mechanism. Furthermore, the balloon catheter movement mechanism is configured for advancement and retraction of the balloon catheter through the handle and catheter lumen by user operation of the balloon catheter movement mechanism.

Acclarent | Date: 2017-05-03

A device and method for dilating a Eustachian tube of a patient is disclosed. The device includes a guide catheter and a balloon dilation catheter. The balloon dilation catheter has an actuator that prevents injury to the middle ear. The balloon dilation catheter is slidably coupled with the guide catheter through the guide catheter lumen and is fully inserted into the guide catheter lumen when the distal side of the actuator is adjacent to the proximal end of the guide catheter. The method involves advancing the guide catheter and balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube.
