Abstract:
1. A device for delivering fluid components of an embolic composition, comprising: an outer tubular element having a distal portion and a lumen for conveying a first fluid component; an inner tubular element having a lumen for conveying a second fluid component, a mixing zone formed within the distal portion of the outer tubular element and outside the distal end of the inner tubular element, said lumens of said inner tubular element and said outer tubular element being in fluid communication with said mixing zone, the inner tubular element being coaxially surrounded by the outer tubular element; a connector for securing the outer tubular element and slidably receiving the inner tubular element to allow axial movement of the inner tubular element relative to the outer tubular element; and a static mixing element disposed within the distal portion of the outer tubular element for mixing said first fluid component and said second fluid component to form the embolic composition, said static mixing element comprising structure other than the walls of side inner tubular element and said outer tubular element and which extends from one of (a) the wall of said inner tubular element or (b) the wall of said outer tubular element, said distal portion of said outer tubular element having a distal tip configured to dispense the embolic composition into a body cavity external to the outer tubular element.
