  • Patent number: 5163950
    Abstract: A balloon catheter with an unreinforced stem collapses compactly. A method of introducing a balloon catheter into the body passage of a patient consists of loading the balloon end of the catheter into the unattached sheath of an endoscope and passing the elongated tubular leg attached to the balloon through the lumen of a working channel of an unattached bridge of an endoscope; then joining the bridge and the sheath to form a unitary endoscope and introducing the balloon into the body passage of a patient. A kit is disclosed which includes a balloon catheter and a separate adapter which can be used to introduce inflating fluid into the balloon.
    Type: Grant

  • Patent number: 4920980
    Abstract: In a catheter which comprises a tubular body having a bore, a wire member is loosely positioned in the bore. The wire member is secured to the catheter at a position adjacent the distal end, such position being radially spaced from the axis of the catheter. The wire member extends through the bore and out of the proximal end of the catheter, so that the distal end of the catheter can be bent by pulling the wire member. The wire member may also be connected at the distal end of the catheter to an electrode, so that the wire member serves both as a bending control member and as the means for electrical connection with the electrode.
