  • Patent number: 10493251
    Abstract: A dilation system includes a handle, a guide member, a balloon dilation member, an actuator, and an endoscope. The handle is configured to provide single-handed use to a user. The guide member is coupled with a distal end of the handle and extends distally therefrom. The balloon dilation member is slidably disposed within the body and the guide member and includes an expandable balloon. The actuator is configured to translate and/or rotate to thereby cause translation and/or rotation of the balloon dilation member. The handle may include a guide member actuator configured to cause translation of the guide member. The handle may further include a rotation mechanism configured to impart rotation upon the guide member. The handle may also include a housing configured to receive and selectively retain the endoscope. The housing is configured to translate and/or rotate to thereby cause translation and/or rotation of the endoscope.

  • Patent number: 10335319
    Abstract: A method for cleaning an isthmus of a Eustachian tube (ET) of a patient includes using an instrument. The instrument includes a proximal portion, a distal portion, and a shaft extending therebetween, and a treatment feature disposed at the distal portion. The method includes directing the instrument into an oro-nasal cavity of the patient and advancing at least the distal portion of the instrument into an opening of the ET. The method further includes further advancing the instrument within the ET so that the treatment feature is disposed past, or is coincident with, the isthmus. The method further includes moving the treatment feature relative to the isthmus to clean the isthmus.

  • Publication number: 20170086868
    Abstract: A dilation system includes a balloon catheter and a puncturing assembly. The balloon catheter includes a shaft, a dilator coupled to a distal end of the shaft, and a lumen extending through the shaft and the dilator. The dilator is expandable from a collapsed state to an expanded state. The puncturing assembly includes at least one cutting member. The puncturing assembly is positionable within the lumen of the balloon catheter or along an exterior of the shaft when the puncturing assembly is in a first position. The puncturing assembly transitions to a second position to puncture the lumen of the balloon catheter and/or to puncture the dilator, to thereby drain fluid from the dilator.

  • Patent number: 6796945
    Abstract: An intravascular imaging guidewire is provided that can accomplish longitudinal translation of an imaging plane allowing imaging of an axial length of a region of interest without moving the guidewire. The imaging guidewire comprises a body in the form of a flexible elongate tubular member. An elongate flexible imaging core is slidably received within the body. The imaging core includes a shaft having an imaging device mounted on its distal end. The body and the imaging core are cooperatively constructed to enable axial translation of the imaging core and imaging device relative to the body. The body has a substantially transparent portion extending an axial length over which axially translatable imaging may be performed. The imaging guidewire has a maximum diameter over its entire length sized to be received within a guidewire lumen of an intravascular catheter.

  • Publication number: 20010029362
    Abstract: A balloon dilatation catheter having a catheter shaft with an oblong transverse cross-section with one transverse dimension in a first direction being significantly larger than a second transverse dimension in a direction perpendicular to the first direction. The first dimension is about 1.1 to about 3 times greater, preferably about 1.2 to about 2.5 times greater than the second dimension. In one embodiment, a length of the distal shaft section has inner and outer tubular members where about 30% to not more than about 90% of the inner periphery of the outer tubular member takes the shape of and is secured to the exterior of the inner tubular member. In another embodiment the flexible distal shaft section is an extruded section having an oval or elliptical transverse cross-section. Preferably a pseudoelastic hypotube of NiTi alloy defines at least part of the inflation lumen within the catheter shaft.
