Abstract: A device, and method for making same, for insertion into a hollow organ of an animal, including humans is disclosed. The device includes a first tubular member having a first diameter, a proximal portion, and a distal portion formed to include a first aperture. The device further includes a tubular access assembly comprising a proximal portion having a second diameter and formed to include a second aperture, and a distal portion having said the diameter, where that distal portion of the access assembly is continuously attached to the proximal portion of the first tubular member, and where the second diameter is greater than or equal to the first diameter. The device further includes an inflatable internal retention assembly disposed around the distal portion of the first tubular member, where that inflatable retention assembly comprises a fluorinated siloxane elastomer.
