Abstract
A medical device for the treatment and irrigation of a sinus opening is described. The device allows for single-handed operation to access, dilate and irrigate a sinus opening. The device includes a sinus guide catheter, a guiding element, a balloon dilation catheter, a balloon catheter movement mechanism and a guiding element movement mechanism. A method for treating a sinus opening and irrigating a sinus is also described.
Claims20
An apparatus comprising:
- (a) a body having a distal end;
- (b) a guide shaft extending distally from the distal end of the body;
- (c) a movable guiding element for accessing a passageway in a head of a patient, the movable guiding element being slidable relative to the guide shaft;
- (d) a dilation catheter for dilating a passageway in a head of the patient, the dilation catheter being slidable relative to the guide shaft;
- (e) a dilation catheter slider slidable along the body;
- and
- (f) a guiding element actuator slidable along the body;
- wherein the dilation catheter slider and the guiding element actuator are slidable along the body for single handed movement of the movable guiding element and dilation catheter to access and dilate the passageway in the head of the patient while the guide shaft is disposed in the head of the patient;
- wherein the guiding element actuator and the dilation catheter slider are configured to be longitudinally co-located with each other;
- wherein the dilation catheter slider is located on top of the guiding element actuator and is configured to slide over the guiding element actuator.

An apparatus comprising:
- (a) a guide shaft;
- (b) a guiding element;
- (c) a guiding element actuator, the guiding element actuator being operable to drive longitudinal movement of the guiding element relative to the guide shaft;
- (d) a dilation catheter comprising:
- (i) a proximal end,
- (ii) a distal end, and
- (iii) a shaft extending between the proximal end and the distal end;
- and
- (e) a dilation catheter actuator located on top of the guiding element actuator and configured to slide over the guiding element actuator, the dilation catheter actuator being secured to the shaft of the dilation catheter, the dilation catheter actuator being operable to drive longitudinal movement of the dilation catheter relative to the guide shaft.
6 more elements
An apparatus comprising:
- (a) a guide member;
- (b) a guidewire assembly, comprising:
- (i) a guidewire, and
- (ii) a guidewire actuator, the guidewire actuator being operable to drive translation of the guidewire relative to the guide member;
- and
- (c) a dilation catheter assembly, comprising:
- (i) a catheter shaft having a proximal portion and a distal portion,
- (ii) an expandable dilator positioned at the distal portion of the catheter shaft, and
- (iii) a dilation catheter actuator positioned at the proximal portion of the catheter shaft, the dilation catheter actuator being operable to drive translation of the dilation catheter shaft relative to the guide member, the dilation catheter actuator including a U-shaped cavity sized and configured to slidably receive the guidewire actuator such that the dilation catheter actuator is configured to be located on top of the guidewire actuator and to slide over the guidewire actuator.
