Abstract
According to some embodiments, the device comprises a tubular member with a longitudinal axis having a proximal end and a distal end, at least one partial cut located at, along or near the distal end of the tubular member, wherein the distal end of the tubular member is configured to at least partially rotate when the force imparting element is advanced relative to the tubular member so at to facilitate placement of the distal end in a particular location of a subject's intraluminal network. The device further includes a transition section intermediate to the at least one partial cut and the non-cut portion of the tubular member.
Claims20
A device comprising:
- a tubular member with a longitudinal axis having a proximal end and a distal end;
- at least one partial cut located at, along or near the distal end of the tubular member, the at least one partial cut comprising an orientation that is angled relative to both the longitudinal axis and an axis transverse to the longitudinal axis;
- a force imparting element positioned colinear to the tubular member and configured to selectively advance the distal end of the tubular member longitudinally, wherein the distal end of the tubular member is configured to at least partially rotate when the force imparting element is advanced relative to the tubular member so at to facilitate placement of the distal end in a particular branch of a subject's intraluminal network;
- and
- a transition section intermediate to the at least one partial cut and the non-cut portion of the tubular member wherein the transition section has at least one partial slot cut to provide a stiffness that is greater than the stiffness of the at least one partial cut located at, along or near the distal end of the tubular member and is less than the stiffness of the non-cut portion of the tubular member;
- wherein the distal end of the tubular member is configured to longitudinally elongate along or near an area of the at least one partial cut.

- wherein movement of the force imparting element relative to the tubular member converts longitudinal displacement into rotational movement, causing the distal end of the tubular member to at least partially rotate when the force imparting element is advanced relative to the tubular member so at to facilitate placement of the distal end in a particular branch of a subject's intraluminal network;
- and
- wherein the distal end of the tubular member is configured to longitudinally elongate along or near an area of the at least one partial cut.
