Abstract
A locking component (100) for locking a catheter proximal end section (32) onto a stem (56) of a medical device such as a venous access port assembly (50). The locking component (100) includes a smaller diameter compression surface (106) along a larger diameter channel (108) therethrough. The device stem (56) includes at least one protuberance (58) of greater diameter than the inner diameter of the catheter end portion (32), and a smaller diameter stem section (66) proximally of the protuberance. Preferably, all protuberances 58) of the stem are rounded. When a stop section (112) of the locking component (100) abuts a corresponding stop section at the proximal end of the stem (56), the compression surface (106) is disposed over and around the smaller diameter stem section (66) and compresses the portion of the catheter proximal end section (32) interposed therebetween thus locking the catheter onto the stem.
