DEFINITION

Classification: 604/101

With plural balloons on conduit:

(under subclass 96) Subject matter wherein multiple inflatable means are mounted on the body inserted conduit.

(1) Note. Patents in this subclass disclose the use of multiple inflating means which inflate inside the body to hold that portion affected in an inflated mode and additional inflating means outside the opening in the body to occlude and seal the opening. Other patents disclose inflating means axially spaced upon the conduit which serve to hold the conduit within the body while inflated.
