Abstract:
A multiple lumen access system for use in providing an entry port into human body for selectively introducing medical devices therethrough and for providing auxiliary access into the body, the system including a multiple lumen access device comprising:an outer tube which has a distal end for introduction into the body and a proximal end; a device lumen defined within the outer tube, the device lumen having a distal end and a proximal end, wherein medical devices may be passed through the device lumen; an auxiliary lumen defined within the outer tube and separately from the device lumen, the auxiliary lumen having a distal end and a proximal end; a flexible wall located within the outer tube having a distal end and a proximal end and opposite sides, wherein one side of the wall partly defines the device lumen and the other side of the wall partly defines the auxiliary lumen, the wall being sufficiently flexible to be movable from a first position, where the device lumen at the particular location has a first cross-sectional area, to multiple flexed positions, where the device lumen at the particular location has corresponding multiple cross-sectional areas which are greater than or less than the first cross-sectional area of the device lumen; and a junction housing having a proximal end and a distal end to which the proximal end of the outer tube connects, the junction housing including a main channel in fluid communication with the device lumen and an auxiliary channel in fluid communication with auxiliary lumen, the main channel and auxiliary channel diverging from each other to be non-intersecting in the junction housing, wherein the outer tube is relatively stiff in relation to the flexible wall to facilitate introduction of the outer tube into a human body.
