Abstract
Devices, systems, and methods for treating chronic rhinosinutisits (CRS) are described herein. The devices can have a guide member defining at least one lumen therethrough. A drug delivery component is advanced through the lumen to deliver a substance to the sino-nasal cavity of a patient. Once the drug delivery component is positioned at the desired area in the sino-nasal cavity, a user actuates the system to deliver the substance to the target area. Actuation of the system delivers the substance to the middle meatus, osteo-meatal complex, or other areas within the sino-nasal cavity of the patient.
Claims13
A drug delivery system for delivering a substance into a subject, comprising:
- a housing for carrying the substance within;
- a guide member configured for insertion at least partially into a nasal cavity of the subject, the guide member having at least one lumen defined therethrough;
- a flexible member translatable through the at least one lumen of the guide member;
- a curved portion defined along the flexible member which forms a loop along the curved portion and having one or more openings defined along the loop at a distal end of the curved portion, wherein the curved portion extends at a predetermined curvature relative to the flexible member when the flexible member is translated from a retracted position to a deployed position and where the loop retains its configuration between the retracted position and the deployed position;
- and
- an alignment guide extending from the housing such that the alignment guide and guide member define an angle configured for positioning the curved portion within a predetermined position within the nasal cavity while the alignment guide and guide member remain stationary relative to one another as the flexible member is translated distally to the deployed position, wherein the guide member and flexible member are rotatable relative to the alignment guide for repositioning the curved portion.
