Abstract: A medical device includes an elongate body and an inflatable balloon attached to and partially surrounding at least a section of the elongate body. The inflatable balloon is selectively inflatable between a deflated state and an inflated state. Engagement between the balloon and a physiological lumen is provided, in part, by multiple protrusions extending from the inflatable balloon and having various physical and functional characteristics. In certain implementations, the balloon may be configured to exhibit various separation forces by applying different strains to the balloon, such as by varying the degree to which the balloon is inflated or deflated.

Abstract: The present invention provides a method of using Raman spectroscopy for identification of low grade cervical cytology cases likely to progress to high grade/cancer. The Applicant has found that high quality Raman spectra can be successfully acquired from morphologically normal appearing cells from negative, LSIL and HSIL Thinprep® specimens and different grades of cervical pre-cancer can be separated with good sensitivities and specificities. Raman spectroscopy can further identify different categories of the LSIL cases i.e., whether they are likely to regress to negative or progress to HSIL cytology.
