Abstract
A lavage catheter for the treatment of a maxillary sinus is described. The catheter comprises a proximal portion and a distal portion. The distal portion comprises an irrigation tip. The irrigation tip has a tip opening through which fluid may be delivered by one handed operation of the catheter. A method for lavaging the maxillary sinus includes inserting the lavage catheter into a patient's anatomy and advancing the irrigation tip into the maxillary sinus using one hand.
Claims20
A method for lavaging a paranasal sinus of a patient, the method comprising:
- (a) providing a lavage catheter instrument comprising:
- (i) a malleable elongate shaft formed from a malleable material,
- (ii) a distal irrigation tube in coaxial arrangement with and coupled with the malleable elongate shaft, wherein the distal irrigation tube includes at least one irrigation hole,
- (iii) a hub disposed proximal to both the malleable elongate shaft and the distal irrigation tube,
- (iv) a proximal irrigation tube having a proximal end and a distal end, wherein the distal end of the proximal irrigation tube connects to a proximal end of the malleable elongate shaft and the distal irrigation tube, and
- (v) a luer connector coupled with the proximal end of the proximal irrigation tube, wherein the luer connector is configured to be coupled with a syringe to provide irrigation fluid for lavage of the paranasal sinus;
- (b) shaping the malleable elongate shaft prior to inserting the lavage catheter instrument into the patient;
- (c) fluidly coupling the syringe to the luer connector of the lavage catheter instrument;
- (d) positioning distal portions of the malleable elongate shaft and the proximal irrigation tube within the paranasal sinus of the patient under visual guidance of an endoscope;
- and
- (e) delivering the irrigation fluid in pulses from the syringe and through the at least one irrigation hole to lavage the paranasal sinus.

- (e) positioning distal portions of the malleable elongate shaft and the proximal irrigation tube within the paranasal sinus of the patient;
- (f) delivering the irrigation fluid from the syringe, through the first lumen, and through the at least one irrigation hole to lavage the paranasal sinus;
- and
- (g) suctioning the paranasal sinus to remove the irrigation fluid.
