Abstract:
1. A catheter assembly comprising: a proximal section having a proximal end and a distal section having a distal end; an inner member extending at least through said distal section and capable of being advanced from a first, retracted position to a second, extended position wherein the inner member extends beyond the distal end of the distal section; said proximal section housing a first member and a second member therein, said first and second members are moveable with respect to each other within said proximal section, said inner member being secured to and moveable with said first member; wherein said second member includes means for limiting travel of the first member within said proximal section, said means for limiting travel housed within said proximal section, and said first member slideable with respect to said means for limiting travel; and wherein the means for limiting travel of the first member is secured to a depth indicator, said depth indicator providing a visual indication of the maximum travel of the inner member beyond the distal end of the distal section; and a third member mounted on the proximal section for moving the second member; and wherein said third member threadingly engages said second member such that rotational movement of said third member translates to lineal movement of said second member.
