Title
(EN) IRISING DRAINAGE DEVICE AND IRISING RECTAL CATHETER
(FR) DISPOSITIF DE DRAINAGE À EXPANSION ET RÉTRACTION ET CATHÉTER RECTAL À EXPANSION ET RÉTRACTION
Abstract
(EN) 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.
(FR) La divulgation concerne un dispositif de drainage à expansion et rétraction, comprenant un entonnoir de collecte à expansion et rétraction ayant une pluralité de pétales chevauchantes s’étendant depuis un anneau définissant une ouverture centrale et un conduit s’étendant depuis l’anneau à l’opposé de l’entonnoir de collecte à expansion et rétraction. Le conduit comprend une lumière en communication fluidique avec l’ouverture centrale. La divulgation concerne un cathéter rectal à expansion et rétraction, comprenant un entonnoir de collecte à expansion et rétraction ayant une pluralité de pétales élastiquement déformables et chevauchantes s’étendant depuis un anneau définissant une ouverture centrale et un tube élastomère s’étendant depuis l’ouverture centrale à l’opposé de l’entonnoir de collecte à expansion et rétraction. Le tube élastomère comprend une lumière en communication fluidique avec l’ouverture centrale. L’entonnoir de collecte à expansion et rétraction est conçu pour se rétrécir élastiquement en réponse à une pression radialement vers l’intérieur et s’expanser avec la réduction de la pression radialement vers l’intérieur. La pluralité des pétales élastiquement déformables et chevauchants, l’anneau, et le tube élastomère sont formés d’un seul tenant les uns avec les autres.
