Abstract
A device for percutaneous administration of fluid preparations into a body cavity, vessel or organ, the device including a tube having both a fluid lumen and an inflation lumen and defined by a proximal end lying outside of the body and a distal end lying within the body, the proximal end of the fluid lumen being in fluid communication with a fluid source and the distal end disposed within the body, the distal end of the inflation lumen in communication with an inflatable member disposed within the body. In one embodiment, one end of the tube is connected to a retention platform having a central portion with a recess to confront the patient's abdominal wall. The retention platform has a plurality of circumferentially-spaced fingers extending radially from said central portion where only the end portion of each finger rests on the abdominal wall of the patient. Preferably, the proximal end of the inflation lumen is remote from the fluid lumen. The device also preferably utilizes a flexible band extending from the retention platform, which carries a plug for sealing the proximal end of the fluid lumen.
