1. A stent comprising:
- an elongate body comprising a tightly coiled wire disposed therealong, the coiled wire spanning between a first end portion and a second end portion, and defining a lumen therethrough;
a safety wire disposed through the lumen and fixed with respect to each of the first and second end portions of the coiled wire;
a proximal end cap distinct from and fixed to a proximal end of the safety wire and a distal end cap distinct from and fixed to a distal end of the safety wire, each of the proximal and distal end caps are fixed with respect to the respective first and second end portions of the coiled wire;
wherein at least one of the proximal and distal end caps comprises a first window in communication with the lumen of the coiled wire and a second window configured to receive the safety wire therethrough, and configured to allow access to the safety wire to join the safety wire and the respective end cap.

Abstract
A stent is provided. The stent includes an elongate body comprising a tightly coiled wire disposed therealong, the coiled wire spanning between a first end portion and a second end portion, and defining a lumen therethrough. A safety wire is disposed through the lumen and fixed with respect to each of the first and second end portions. Proximal and distal end caps are fixed to the ends of the safety wire. At least one of the proximal and distal end caps comprises a window configured to receive the safety wire therethrough, and configured to allow access to the safety wire to weld the safety wire and the respective end cap.

8. A stent, comprising:
-
an elongate central portion comprising a coiled wire disposed to define a plurality of coils disposed proximate to each other along a length of a stent between proximal and distal end portions with a lumen disposed therethrough, the plurality of coils each coiled to form a first outer diameter; further comprising a safety wire disposed through the lumen of the stent and fixed to one or both of the proximal and distal end portions; wherein the proximal end portion of the coiled wire comprises an outer diameter, the outer diameter being tapered at the proximal end portion of the coiled wire toward a proximal end tip upon the proximal end portion of the coiled wire; further comprising a weld bead disposed upon the proximal end tip of the coiled wire, wherein an outer diameter of the weld bead is less than the first outer diameter but greater than the outer diameter of the proximal end tip of the coiled wire; further comprising a grasper comprising two or more arms that extend from a control portion, wherein each of the arms are configured to extend over the proximal end tip; wherein a maximum outer diameter of the two or more arms is equal to or smaller than the first outer diameter. - View Dependent Claims (9)

10. A stent comprising:
-
an elongate body comprising a tightly coiled wire disposed therealong, the coiled wire spanning between a first end portion and a second end portion, and defining a lumen therethrough; a safety wire disposed through the lumen and fixed with respect to each of the first and second end portions of the coiled wire; a proximal conical end cap fixed to a proximal end of the safety wire and a conical distal end cap fixed to a distal end of the safety wire, each of the proximal and distal end caps are fixed with respect to the respective first and second end portions of the coiled wire; wherein at least one of the proximal and distal end caps comprises a first window in communication with the lumen of the coiled wire and a second window configured to receive the safety wire therethrough, and configured to allow access to the safety wire to join the safety wire and the respective end cap. - View Dependent Claims (11, 12, 13, 14, 15, 16)
