Abstract
Systems and methods can be employed for trans-tympanic membrane access to the middle ear for delivery of a formulation or implant device to a target location under direct visualization. The systems and methods can also be used to improve accessibility and visualization for various otological surgical procedures, such as, but not limited to, cholesteatoma removal, tympanic membrane repair and ossicular chain repair.
Claims20
A system for delivering formulation at a target location in a middle or inner ear of a patient, the system comprising:
- an endoscope including an endoscope shaft with a distal tip portion sized to be positioned within a middle ear;
- a sleeve device defining:
- (i) a first lumen configured to slidably receive the endoscope shaft and (ii) a second lumen;
- an injection device including a proximal actuator and an injection shaft with a distal tip portion defining a distal delivery port, the injection shaft sized to be slidably received in the second lumen of the sleeve device, the distal tip portion of the injection shaft being adjustable from a longitudinally straight shape to a curved shape to orient the distal delivery port at the target location in the middle or inner ear;
- and
- a formulation source in fluid communication with the injection device so that the distal delivery port is configured to deliver the formulation at the target location while the distal tip portion of the injection device is arranged in the curved shape.
A system for delivering an implant device to a target location in a middle or inner ear of a patient, the system comprising:
- an endoscope including an endoscope shaft with a distal tip portion sized to be positioned within a middle ear;
- a sleeve device defining:
- (i) a first lumen configured to slidably receive the endoscope shaft and (ii) a second lumen;
- and
- an implant delivery device including a proximal actuator and a shaft with a distal tip portion configured to releasably couple with an implant device, the shaft sized to be slidably received in the second lumen of the sleeve device, the distal tip portion of the implant delivery device being adjustable from a longitudinally straight shape to a curved shape to orient the distal tip portion at the target location in the middle or inner ear.
A system for delivering an implant device to a round window niche of a patient, the system comprising:
- an endoscope including an endoscope shaft with a distal tip portion sized to be positioned within a middle ear of the patient;
- an implant device comprising a formulation for sustained released to the round window niche;
- and
- an implant delivery device including a proximal actuator and a shaft with a distal tip portion configured to releasably couple with the implant device, the distal tip portion of the implant delivery device being adjustable from a longitudinally straight shape to a curved shape to orient the distal tip portion at the round window niche.
