  • Publication number: 20140277071
    Abstract: A dilation assembly includes a shaft and a dilator coupled with the distal end of the shaft. The dilator includes a proximal end, a distal end, and a center portion positioned between the proximal end and the distal end. The center portion dilates from a first configuration to a second configuration. The center portion has a larger diameter than the proximal end and the distal end when the center portion is in the second configuration. At least one gripping feature is positioned on at least a portion of the exterior surface of the center portion. The gripping feature provides friction between the center portion and a bodily lumen when the center portion is in the second configuration.

  • Publication number: 20130274715
    Abstract: 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.

  • Patent number: 8114062
    Abstract: Devices and methods for delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects. An implantable delivery device comprising a reservoir is initially attached to a deliver catheter or delivery tool and is introduced into the body and positioned at a desired site. A therapeutic or diagnostic substance is then introduced into the reservoir and the delivery catheter or deliver tool is then removed, leaving the implantable delivery device implanted within the body. The substance is then delivered from the reservoir at a rate that causes the desire diagnostic or therapeutic effect. Also provided are substance eluting stents that elute substance from a selected surface of the stent (e.g., the outer surface) but not from another surface of the stent (e.g., the inner surface).
