Patent ID: 11103377

Abstract:
An irising drainage device is disclosed, including an irising collection funnel having a plurality of overlapping petals extending from an annulus defining a central aperture and a conduit extending from the annulus away from the irising collection funnel. The conduit includes a lumen in fluid communication with the central aperture. An irising rectal catheter is disclosed, including an irising collection funnel having a plurality of overlapping elastically deformable petals extending from an annulus defining a central aperture and an elastomeric tube extending from the central aperture away from the irising collection funnel. The elastomeric tube includes a lumen in fluid communication with the central aperture. The irising collection funnel is configured to elastically narrow in response to a radially inward pressure and expand with reduction of the radially inward pressure. The plurality of elastically deformable overlapping petals, the annulus, and the elastomeric tube are integrally formed with one another.
