Patent ID: 7491190

Claim:
A securement system comprising: a medical device having an elongated tubular body and at least first and second axially extending splines, the second axially extending spline having a greater longitudinal length than the first axially extending spline and; a retainer comprising: a base surface for attachment to an anchor pad, a proximal end portion and a distal end portion spaced apart from each other and which extend about a longitudinal axis, each of the proximal and distal end portions being sized to surround at least a portion of the medical device through an arc of greater than 180 degrees about said longitudinal axis, a channel extending though at least the proximal and distal end portions, an opening located in the proximal end portion and having a diameter less than a diameter of the channel, a pair of longitudinally opposed abutment surfaces, each of which is formed on one of the proximal and distal end portions and being disposed between a distal end and a proximal end of the retainer, the abutment surfaces generally facing each other and being spaced longitudinally apart from each other by a distance that generally corresponds to the longitudinal length of the second spline of the tubular body, and a pair of walls disposed between the proximal and distal end portions. at least a portion one of the walls being configured to contact at least a portion of the second spline at least when the medical device is secured within the channel, the contacting portion of the second spline being disposed between distal and proximal ends of the second spline.
