Abstract

The invention features an improved catheter design with a rotatable member attached to the proximal end of a catheter. The rotatable member can lock a flexible tension member, passing through the catheter, in place and thereby prevent both inadvertant removal of the catheter and wicking to the outside along the flexible tension member.
