US Patent 8162897 Audible and tactile feedback

A rotational locking mechanism for securing a catheter to a surgical implant is disclosed. The locking mechanism includes a deflectable extension extending from the surgical implant about the catheter attached to the surgical implant. The shape of the deflectable extension defines a slot therein. A connector having at least one tab extending therefrom is placed about the catheter at the point of attachment to the surgical implant. Rotation of the tubular connector brings at least one tab of the connector into contact with the slot in the deflectable extension and deflects and releases at least a portion of the slot as the connector rotates from an unlocked position to a locked position within the slot. The rotation motion secures the catheter to the surgical implant, and produces a feedback detectable by a surgeon rotating the tubular connector.
