<p num="1"><br/><br/><br/>An infusion device (100) comprising an infuser base (105), a cannula (115) and <br/>a ferrule (120). The infuser base (105) having a bore (104) extending <br/>therethrough, the bore (104) having a distal and proximal ends the proximal <br/>end having an inside first diameter. A flange (135) extends radially outward <br/>from the cannula proximal end. The cannula (115) is positioned in the bore <br/>(104) such that the flange (135) is positioned adjacent the shoulder (109). <br/>The ferrule (120) has an insertion portion (122), having an outside second <br/>diameter which is substantially equal to the first diameter, and a tapered <br/>portion (125) extending from the insertion portion (122). The ferrule (120) is <br/>positioned in the bore (104) such that the insertion portion (122) and a <br/>portion of the tapered portion (125) are received in the cannula proximal end <br/>and the flange (135) is compressed between the shoulder (109) and the tapered <br/>portion (125) to define a seal (160) between the cannula (115) and the ferrule <br/>(120).<br/>
