Abstract
The present invention relates to an endoluminal device for implantation in a body lumen, such as a pancreatic duct. The device is provided with a distal end region having greater flexibility than that of a medial region of the device.
Claims19
An endoluminal device comprising:
- a stent having a proximal end region and a distal end region and a longitudinal axis extending therebetween, the stent formed from a plurality of wires;
- and
- wherein the distal end region includes a plurality of loops formed by the plurality of wires, each loop being formed by an end region of a first wire of the plurality of wires connected to an end region of a second wire of the plurality of wires at a joining region, each loop having only one joining region, each loop overlapping only two circumferentially adjacent loops;
- wherein each loop has straight side portions extending substantially parallel to the longitudinal axis.

An endoluminal device comprising:
- a stent having a proximal end region, a medial region, a distal end region, and a longitudinal axis extending between the proximal end region and the distal end region, the stent formed from a plurality of wires;
- wherein the distal end region includes a plurality of loops formed by the plurality of wires, each loop overlapping only two circumferentially adjacent loops, each loop defined by a proximal cross-over point of a first wire and a second wire, straight side portions of the first and second wires, a distal end bend of the first wire, and a joining region joining end regions of the first and the second wires;
- and
- wherein the straight side portions of the first and second wires extend substantially parallel to the longitudinal axis, wherein there is no contact between the straight side portions of circumferentially adjacent loops.

An endoluminal device comprising:
- a stent having a proximal end region, a medial region, a distal end region, and a longitudinal axis extending between the proximal and the distal end regions, the stent formed from a plurality of wires;
- wherein the distal end region includes a plurality of loops formed by the plurality of wires, each loop overlapping only two circumferentially adjacent loops, each loop defined by only two wires forming a proximal cross-over point where a first wire extending in a first helical direction crosses over a second wire extending in a second helical direction different from the first helical direction, straight side portions of the first and second wires positioned distal of the proximal cross-over point, and a joining region joining end regions of only the first and the second wires.
