Abstract
Systems and methods can be employed for access to the middle ear for delivery of a formulation to a targeted site under direct visualization. The formulation, in some cases, can be delivered to a cochlear implant lead insertion site where a lead of a cochlear implant device enters a patient’s cochlea.
Claims20
A method of treating a cochlear implant lead insertion site of a cochlea, comprising:
- advancing a therapeutic gel delivery shaft of a handheld injector tool toward a cochlear implant lead through a transmastoid pathway such that a distal port of the therapeutic gel delivery shaft is proximate to a cochlear implant lead insertion site of a cochlea,
- depositing a therapeutic gel out of the distal port of the therapeutic gel delivery shaft onto the cochlear implant lead insertion site while the therapeutic gel delivery shaft is positioned through the transmastoid pathway;
- and
- during said depositing the therapeutic gel, using a tip-mounted image capture device fixedly mounted at a distal end of a visualization shaft of the handheld injector tool to provide direct visualization of both the therapeutic gel delivery shaft and the cochlear implant lead insertion site, wherein the therapeutic gel delivery shaft and the visualization shaft are side-by-side shafts fixedly mounted to a handle of the handheld injector tool such that the distal port of the therapeutic gel delivery shaft is positioned distally of the distal end of the visualization shaft.
