Abstract
A catheter movement control device is provided which allows forward, extending movement of the catheter tube contained within a flexible package to the exterior thereof as required during insertion. The method of use includes moving the catheter tube through the control device to exit the catheter package where it is inserted into the urethra. If resistance is encountered during insertion a stop member firmly engages the catheter tube to prevent rearward movement of the catheter tube under normal urging.
Claims8
A method of controlling the movement of a catheter having an extendable tube contained within a package with a control device having a stop member comprising a roller which will slide forwardly and rearwardly, said stop member mounted to engage the catheter tube, comprising the steps of:
- a) urging the catheter tube through the control device in a forward direction to extend the catheter tube from the package;
- and
- b) engaging the catheter tube with the stop member by sliding the stop member within the control device to tightly engage the catheter tube to thereby prevent the catheter tube from withdrawing into the package.
A method of controlling the movement of a catheter having an extendable tube contained within a package with a control device having a slidable stop member comprising a roller with radially extending teeth, said control device mounted so said roller teeth contact the catheter tube, comprising the steps of:
- a) urging the catheter tube through the control device in a forward direction to extend the catheter tube from the package;
- and
- b)sliding the roller within the control device, and
- c) engaging the catheter tube with the teeth of the roller to thereby prevent the catheter tube from withdrawing into the package.
