Abstract
Described herein is a method for treating a narrowed region of a lumen in the ear or nose of a patient. The method includes advancing a catheter within the lumen such that a distal end of the catheter is positioned proximate to the narrowed region, filling a fillable member to expand the fillable member within the lumen, and generating at least one shock wave from at least one shock wave emitter. The at least one shock wave creates one or more fractures in a bony structure of the narrowed region of the lumen that dilate the narrowed region.
Core Innovation
The invention relates to treating a narrowed region of a lumen in the ear or nose of a patient by advancing a catheter so that a distal end of the catheter is positioned proximate to the narrowed region. The distal end includes at least one shock wave emitter surrounded by a fillable member, and the fillable member is filled to expand within the lumen.
Shock waves are generated from the at least one shock wave emitter such that the shock waves create one or more fractures in a bony structure of the narrowed region of the lumen. The fractures dilate the narrowed region, providing treatment of the narrowed lumen in the ear or nose.
A device version of the invention includes an elongated tube, at least one shock wave emitter configured to generate at least one shock wave along a working direction, and at least one imaging sensor oriented to capture images along the working direction. The device further includes a fillable member sealed to a distal end of the elongated tube, surrounding the at least one shock wave emitter and the at least one imaging sensor, where the fillable member is fillable with a conductive fluid.
The disclosed system emphasizes targeted localization and delivery by using imaging sensors and positioning along a working direction, in combination with a sealed distal fillable member surrounding the shock wave emitter and imaging sensor. Conductive fluid is used in the fillable member, and dependent variations describe drug-coated fillable members for delivering an active agent to the lumen.
Claims Coverage
The provided document includes two independent claims. Each independent claim defines a core inventive combination: a shock-wave treatment method using a catheter with a distal fillable member that expands in the lumen and fractures a bony structure to dilate a narrowed region, and a corresponding treatment device with a sealed distal fillable member containing conductive fluid and imaging sensors aligned with a working direction.
Catheter with distal shock wave emitter surrounded by expandable fillable member to dilate narrowed ear/nose lumen
A method for treating a narrowed region of a lumen in the ear or nose by advancing a catheter such that a distal end is positioned proximate to the narrowed region, the distal end having at least one shock wave emitter surrounded by a fillable member; filling the fillable member to expand the fillable member within the lumen; and generating at least one shock wave from the at least one shock wave emitter, the shock wave creating one or more fractures in a bony structure of the narrowed region that dilate the narrowed region.
Device with imaging sensor capture along working direction and sealed conductive-fluid fillable member surrounding shock wave emitter
A device for treating a narrowed region of a lumen in the ear or nose including an elongated tube; at least one shock wave emitter configured to generate at least one shock wave along a working direction; at least one imaging sensor oriented to capture images along the working direction; and a fillable member sealed to a distal end of the elongated tube and surrounding the at least one shock wave emitter and the at least one imaging sensor, the fillable member being fillable with a conductive fluid.
Across the independent claims, the inventive concept combines shock wave generation for fracturing a bony structure to dilate a narrowed ear/nose lumen with a catheter or device architecture that includes a distal fillable member. The device claim further adds imaging sensor capture oriented along the working direction, with the distal fillable member sealed around both the shock wave emitter and imaging sensor and filled with conductive fluid.
Stated Advantages
Dilates the narrowed region of a lumen in the ear or nose by creating one or more fractures in a bony structure.
Documented Applications
Treating a narrowed region of a lumen in the ear or nose of a patient using a shock wave catheter device and methods that expand a distal fillable member and generate shock waves to fracture bony structure.
