Abstract
A suctioning and irrigating sinus balloon catheter is provided for treating a patient'"'"'s paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities and choana. The catheter has a number of fluid carrying conduits to provide irrigation, suction and inflation/deflation to the distally mounted balloon. The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, choana or sinus to be excised. Some catheters can be hand bendable by the surgeon. Some catheters provide the capability of threading an endoscope through one of the conduits. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, choana, and/or to dilate sinus cavities to remove them.

60. A method of treating a paranasal sinus of a patient using an elongate member, wherein the elongate member comprises a shaft and a treatment feature disposed on the shaft, wherein at least a distal portion of the elongate member is configured to be laterally bendable and inserted into a nostril of the patient, the method comprising:
-
(a) identifying an anatomical structure associated with the paranasal sinus of the patient; (b) using a bending tool to laterally bend at least the distal portion of the elongate member relative to a proximal portion of the elongate member during a medical procedure, with the bending being performed according to the identified anatomical structure such that the distal portion is disposed relative to the proximal portion of the elongate member at a bend angle; (c) inserting the distal portion of the elongate member into a nostril of the patient; (d) directing the distal portion of the elongate member via the bend angle such that at least the distal portion is within or adjacent to one of the paranasal sinuses, wherein the distal portion maintains the formed bend angle during the act of directing; and (e) treating the paranasal sinus using the treatment feature. - View Dependent Claims (61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72)

73. A method of treating a paranasal sinus of a patient using a balloon catheter, wherein the balloon catheter comprises an elongate shaft including an expandable balloon disposed thereon, wherein at least a distal portion of the balloon catheter is configured to be inserted into a nostril of the patient, the method comprising:
-
(a) identifying an anatomical structure associated with the paranasal sinus of the patient; (b) deforming at least the distal portion of the shaft manually by using a bending tool, according to the identified anatomical structure; (c) inserting the distal portion of the shaft into a nostril of the patient; (d) directing the distal portion of the shaft to the target treatment area, wherein the distal portion maintains the deformation during the act of directing; and (e) dilating the target treatment area with the expandable balloon. - View Dependent Claims (74, 75, 76, 77, 78)

79. A method of treating a paranasal sinus of a patient using an elongate member, wherein the elongate member comprises a shaft and a treatment feature disposed on the shaft, wherein at least a distal portion of the elongate member is configured to be inserted into a nostril of the patient, the method comprising:
-
(a) identifying an anatomical structure associated with the paranasal sinus of the patient; (b) manipulating at least the distal portion of the elongate member according to the identified anatomical structure to form a bend in the elongate member according to the identified anatomical structure, wherein the act of manipulating comprises using a bending tool; (c) inserting the distal portion of the elongate member into a nostril of the patient; (d) directing the distal portion of the elongate member such that at least the distal portion is within or adjacent to one of the paranasal sinuses, wherein the bend is retained along the distal portion during the act of directing; (e) irrigating the paranasal sinus with a liquid delivered through the shaft to the treatment feature; and (f) suctioning the liquid and other material in or adjacent to the paranasal sinus at the treatment feature through the shaft.
