Abstract
A grabbing device includes a transparent flexible cup that can be placed adjacent to a selected region of an inner surface of a body cavity. The flexible cup is visually put in place by the surgeon, and a vacuum is applied to draw a selected amount of tissue into the flexible cup, so that it may, e.g., be excised. The device may also retrieve the tissue excised from the body cavity.
Claims6
A method for removing a selected portion of tissue from a surface of a body cavity, comprising the step of:
- inserting into the body cavity an insertion device;
- advancing through the insertion device a substantially transparent flexible cup in a folded configuration within the insertion device;
- deploying the flexible cup from the insertion device in a substantially funnel shaped configuration;
- visually positioning the deployed flexible cup adjacent to the selected portion of tissue by observing the selected portion of tissue through the substantially transparent flexible cup;
- applying a vacuum pressure through the flexible cup to draw the selected portion of tissue into the flexible cup;
- and
- at least partially withdrawing the flexible cup proximally into the insertion device to draw the selected portion of tissue into desired position relative to the insertion device.
