Abstract:
1. A medical device with an anchor assembly, comprising: an elongate member having a proximal end and a distal end, the elongate member comprising a longitudinally oriented first channel comprising a length that is recessed and open to a radial outer surface of the elongate member near the distal end; a smaller lumen extending from the first channel, through the elongate member, and communicating with an exterior opening configured to be disposed outside of a patient; a pivotable anchor comprising an entire length that is removably disposed within the first channel, the pivotable anchor comprising a proximal end adjacent a distal opening of the smaller lumen when the pivotable anchor is disposed within the first channel, the proximal end being larger in size than the distal opening of the smaller lumen such that the pivotable anchor does not extend into the smaller lumen, the pivotable anchor being movable from the first channel to a perpendicular orientation outside the first channel and adjacent to the elongate member and the distal opening of the smaller lumen, the distal end of the elongate member thereby being fixed a predetermined distance from the pivotable anchor when the pivotable anchor is in the perpendicular orientation and adjacent the elongate member and the distal opening of the smaller lumen; a larger lumen extending from a separate exterior opening configured to be disposed outside of the patient, through the elongate member, and opening distal from the distal opening of the smaller lumen; a biocompatible filament having a first attached end affixed to the anchor and a second unattached proximal end configured to be disposed outside of the patient, the filament proximally extending from the first attached end to the second unattached end within the smaller lumen of the elongate member; wherein the anchor is configured to pivot from a longitudinal orientation within the first channel to the perpendicular orientation outside the first channel upon application of a tensile force to the second unattached proximal end of the filament, the anchor in the perpendicular orientation being configured to engage against a body wall to inhibit movement of the elongate member thereto.
