Abstract: The present invention is related to an apparatus for uterine anesthesia that comprises an outer tube and an inner tube positioned within the outer tube. The apparatus is positioned in the cervical os of a patient and an anesthetic is dispensed through the inner tube. A stopper surrounding the inner tube prevents a drainage of the anesthetic through the interstice between the two tubes, while an applicator surrounding the outer tube prevents a loss of the anesthetic along the cervical walls and into the vaginal canal. The applicator also maintains the cervical os in a dilated position, operating as a tenaculum and providing access to the uterus by a clinician. Methods for providing uterine anesthesia are also provided.

Abstract: Apparatus and methods for endometrial biopsies, wherein an applicator is disposed on the distal end of an outer tube and an injection device is connected to the proximal end of the same tube. The applicator comprises one or more ridges on its outer surface that anchor the applicator in the cervical os, and that cause the applicator to remain securely positioned and maintain the os in a dilated position during the entire procedure. The ridges may be shaped like protrusions, scalloped edges or grooves, and may be disposed in a helical or circular pattern. A method for performing endometrial biopsies is also provided. The apparatus and methods according to the present invention are configured to minimize discomfort to the patient while facilitating the operation of the clinician.

Abstract: Apparatus and methods are provided for applying anesthetic or other medication to a desired location within a patient's uterus and for collecting cells, wherein an inner tube is configured to reciprocate through the lumen of an outer tube. The outer tube includes a foam applicator that facilitates delivery of anesthetic to the uterus prior to the cell collection procedure.

Abstract: A cervical tissue sampling system is provided that includes a tissue cutting device and a snare. The tissue cutting device features a conical tip coupled to an elongated body and having a tapered helical cutting edge that defines a tissue receiving channel. The snare includes an elongated body, an adjustable wire loop and a stopper, the stopper arranged to lock the wire loop with a desired degree of tension around the cervix to assist in positioning the tissue cutting device.

Abstract: Apparatus is provided for accessing a body cavity comprising kit containing an annular member having a deflated insertion configuration and an inflated expanded configuration and an expandable support assembly including an upper lever coupled to a handle, wherein the expandable support assembly may be deployed within the inflatable body to enhance the radial strength of the inflatable body and provide an unobstructed view.
