Patent ID: 7452354

Claim:
A connection device for attaching a catheter to an implantable port or pump, wherein the catheter is in fluid communication with said port or pump, comprising: a coupling device for extending from said port or pump, comprising an arm portion and a stem, wherein the shape of the arm portion is substantially similar to an outer contour of said port or pump, and wherein the stem comprises a base portion and a tip portion, said base portion having a forward portion having a forward portion diameter and an engaging locking portion having varying engaging locking portion diameters including a largest engaging locking portion diameter that is larger than said forward portion diameter, said stem further comprising a connecting portion connecting said base portion to said arm, said connecting portion having a diameter smaller than said largest engaging locking portion diameter, said tip portion having a tip portion diameter; and a locking device slideable along a length of the catheter, comprising varying diameter portions that communicate directly with diameters of the base portion of the stem, said locking device including a first diameter portion larger than said tip portion diameter, a second diameter portion for mating with said forward portion, a third diameter portion substantially equal to said largest engaging locking portion diameter, and a fourth diameter portion smaller than said largest engaging locking portion diameter, whereby when said catheter is inserted onto said tip portion and said locking device is slid onto said stem, a primary locking connection and fluid seal are created in said first diameter portion between said tip portion and said catheter, a secondary locking connection is established in said third diameter portion, and said connecting portion is positioned in said fourth diameter portion, wherein said primary and secondary locking connection are achieved without requiring rotation of said locking device relative to said stem, and whereby lateral movement of said catheter is prevented.
