INTRAVASCULAR BALLOON WITH SLIDABLE CENTRAL IRRIGATION TUBE

A balloon catheter (100) has a central tube (102) that is configured to both structurally support and inflate a balloon membrane (162). The central tube has a lumen (103) and sidewall inflation ports (104) that provide a path for inflating the balloon. The lumen of the central tube is obstructed by...

Beschreibung
Zusammenfassung:	A balloon catheter (100) has a central tube (102) that is configured to both structurally support and inflate a balloon membrane (162). The central tube has a lumen (103) and sidewall inflation ports (104) that provide a path for inflating the balloon. The lumen of the central tube is obstructed by a distal end piece (106), nose piece, or other structure to prevent fluid from exiting a distal end of the central tube. The central tube is configured such that, during inflation, inflation media is allowed to pass through an elongated shaft of the catheter, into a proximal open end of the central tube, and through the inflation ports into the balloon. The central tube can slide longitudinally in relation to the shaft to longitudinally elongate and/or truncate the balloon.
