  • Patent number: 10524869
    Abstract: An apparatus may be used to form an opening in a sinus wall. The apparatus comprises a first cutting member and a second cutting member. The first cutting member comprises a helical blade. The second cutting member is slidably disposed about the first cutting member. The second cutting member comprises a sharp distal edge. An outer sheath is slidably disposed about the first and second cutting member. The sheath may be retracted to uncover the helical blade.

  • Patent number: 10517608
    Abstract: An instrument for treating a sinus cavity includes a cutter member, a rotatable member, and a fluid passage. The cutter member has a lumen extending therealong, and the rotatable member is received within the lumen. The rotatable member has a helical blade projecting from a distal end portion. The cutter member is configured to translate relative to the rotatable member. Thereby, the cutter member and the rotatable blade are configured to form an opening into the sinus cavity. The fluid passage extends through the cutter member from an inlet to an outlet. The outlet is positioned proximal to the helical blade such that the outlet is configured to fluidly communicate with the sinus cavity. The inlet is configured to receive at least one of a fluid and a vacuum in order to communicate the respective fluid or vacuum to the outlet for irrigating or suctioning the sinus cavity.
