Abstract
A device and method for delivering an agent to the uterine cervix make use of a seal member that defines a chamber upon engagement with the cervix. An agent delivery port in fluid communication with the chamber is provided for delivery of the agent to the uterine cervix. A vacuum port in fluid communication with the chamber allows application and retention of vacuum pressure to the chamber. At least a portion of the seal member can be made deformable in response to contact with the outer surface of the uterine cervix and application of vacuum pressure. Upon deformation, the seal member substantially seals the chamber against leakage of the agent. The seal member may include a skirt-like member that promotes adhesion of the seal member to the cervix, and enhances the effectiveness of the seal. The device facilitates vacuum application, cervical fixation, and a resulting barrier against uterine fluid leakage, providing an atraumatic, temporary cervical plug that remains effective while the vacuum is applied. In this manner, the device is capable of improving diagnostic or therapeutic effectiveness while reducing waste and expense. The device and method also can be adapted for introdu…
