Abstract
A manipulator, including an elongated chassis containing a U-shaped channel defining a distal direction and a proximal direction. The manipulator also includes an adjuster that is configured to slide in the U-shaped channel. The adjuster includes a first wheel which on rotation translates a guidewire positioned in the adjuster along an axis of the guidewire, and a second wheel which on rotation rotates the guidewire positioned in the adjuster about the axis of the guidewire. The adjuster also includes a port, distal to the first and the second wheel, that is configured to accept a tubular balloon and the guidewire.
Claims20
A guidewire, comprising:
- (a) a plastic tube forming a lumen, the plastic tube being configured to be inserted into a nasal sinus and having a length;
- (b) a braid incorporated into the plastic tube;
- and
- (c) a metal wire located in the lumen along the length of the plastic tube,
- the plastic tube including a first plastic tube cemented to a second plastic tube, the lumen being common to the first plastic tube and the second plastic tube, and the first and second plastic tube having different thicknesses and a same outside diameter along the length of the plastic tube.
A guidewire, comprising:
- (a) a flexible tube including a proximal end and a distal end, the flexible tube forming a lumen, the flexible tube being configured to be inserted into a nasal sinus the flexible tube defining a longitudinal axis, the flexible tube having a same outside diameter along a length of the flexible tube and the proximal end having a greater thickness than the distal end;
- (b) a braid being incorporated coaxially embedded within the flexible tube relative to the longitudinal axis;
- and
- (c) a support wire being disposed in the lumen.
A guidewire, comprising:
- (a) a flexible tube configured to be inserted into a paranasal passageway, including:
- (i) a proximal tube portion defining a proximal end, and
- (ii) a distal tube portion defining a distal end, the proximal and distal tube portions being axially adjoined and defining a lumen therethrough from the proximal end of the proximal tube portion to the distal end of the distal tube portion and the proximal tube portion and distal tube portion having differing flexibilities;
- and
- (b) a support braid being embedded within the flexible tube from the proximal end to the distal end,
- the flexible tube having a same outside diameter in both the proximal tube portion and the distal tube portion,
- the proximal tube portion having a proximal inner diameter, the distal tube portion having a distal inner diameter, and the proximal inner diameter being smaller than the distal inner diameter, and the proximal tube portion having a greater thickness than the distal tube portion.
