Self-Contained Inserter For Drug Delivery Infusion Set
First Claim
1. An infusion set, comprising:
- a base;
a flexible catheter movable from a first catheter position disposed substantially entirely within said base to a second catheter position in which a free end of said catheter is disposed externally of said base;
an introducer needle located within said catheter and movable between a first introducer needle position disposed substantially entirely within said base and a second introducer needle position in which a free end of said introducer needle is disposed externally of said base; and
an activation button movable between first and second button positions, wherein when said button is moved from said first button position to said second button position, said catheter is moved from said first to said second catheter position, said introducer needle is moved from said first to said second introducer needle position to facilitate insertion of said catheter, and said introducer needle is thereafter moved back to said first introducer needle position to store said introducer needle within said base with said free end of said catheter remaining disposed externally of said base.

Abstract
An infusion set (101) includes a base (121), a flexible catheter (142) and an introducer needle (134). The flexible catheter (142) is movable from a first catheter position disposed substantially entirely within the base (121) to a second catheter position in which a free end of the flexible catheter (142) is disposed externally of the base (121). The introducer needle (134) is movable between a first introducer needle position disposed substantially entirely within the base (121) and a second introducer needle position in which a free end of the introducer needle (134) is disposed externally of the base (121). An activation button (161) is movable between first and second button positions. When the activation button (161) is moved from the first button position to the second button position, the flexible catheter (142) is moved from the first to the second catheter position, and the introducer needle (134) is moved from the first to the second introducer needle position to facilitate insertion of the catheter (142) and back to the first introducer needle position to store the introducer needle (134) within the base (121).
