Abstract
Various aspects of methods, systems, and use cases may be used to inflate a balloon catheter using a syringe. The syringe may include a channel portion shaped to create a channel, and a plunger, for example including an inserted end and a free end, which when inserted in the channel to place the inserted end at a plunger starting position, causes a starting pressure to be applied to the balloon catheter. In an example, the channel portion or the plunger includes at least one visual indicia indicating the plunger starting position, the plunger starting position located along an insertion axis (e.g., of the channel portion and the plunger).
Claims18
A syringe for inflating a balloon catheter, the syringe comprising:
- a channel portion including a balloon catheter insertion end and a plunger receiving end, the channel portion shaped to create a channel, the channel portion including a groove at a plunger starting position located between the balloon catheter insertion end and the plunger receiving end;
- a plunger, including an inserted end and a free end;
- and
- an outer surface of the inserted end of the plunger includes a raised bump corresponding with the groove such that the outer surface of the of the inserted end of the plunger locks into the channel portion at the plunger starting position and maintains an atmospheric pressure within the balloon catheter;
- wherein when the plunger is advanced in the channel from the plunger starting position toward the balloon catheter insertion end an inflation pressure for the syringe above the atmospheric pressure is applied to the balloon catheter and when the plunger is retracted in the channel from the plunger starting position toward the plunger receiving end, a deflation pressure for the syringe below the atmospheric pressure is applied to the balloon catheter.
A method for using a syringe to inflate a balloon catheter, the method comprising:
- affixing the syringe to the balloon catheter, wherein the syringe includes:
- a plunger, including an inserted end and a free end;
- and
- a channel portion, the channel portion including a balloon catheter insertion end and a plunger receiving end, the channel portion shaped to create a channel:
- inserting the inserted end of the plunger into the channel created by the channel portion;
- locking a raised bump located on an outer surface of the inserted end of the plunger into a groove located on the channel portion at a plunger starting position located between the balloon catheter insertion end and the plunger receiving end to maintain an atmospheric pressure within the balloon catheter;
- inserting the balloon catheter to a target location within a patient airway;
- and
- applying a force to the plunger to move the plunger further into the channel portion including moving the insertion end to an inflation position to cause the balloon of the balloon catheter to inflate to an inflation pressure.
A kit comprising:
- at least two balloon catheters with balloons of different sized maximum outer diameters;
- and
- a syringe including:
- a channel portion including a balloon catheter insertion end and a plunger receiving end, the channel portion shaped to create a channel and further including a groove at a plunger starting position located between the balloon catheter insertion end and the plunger receiving end;
- a plunger, including an inserted end and a free end;
- and
- an outer surface of the inserted end of the plunger including a raised bump corresponding with the groove such that the outer surface of the inserted end of the plunger locks into the channel portion at the plunger starting position and maintains an atmospheric pressure within the at least two balloon catheters;
- and
- wherein when the plunger is advanced in the channel from the plunger starting position toward the balloon catheter insertion end an inflation pressure for the syringe above the atmospheric pressure is applied to the at least two balloon catheters and when the plunger is retracted in the channel from the plunger starting position toward the plunger receiving end, a deflation pressure for the syringe below the atmospheric pressure is applied to the at least two balloon catheters.
