Abstract
This disclosure is directed primarily to a stent for use in the trachea. The stent has a nominally deployed state, an axially extended state and an axially compressed state. The stent has a length. In the axially extended state, the length is at least 20% greater than in the nominally deployed state.
Claims20
A stent, comprising:
- a tubular scaffold including a diameter and a plurality of strut columns alternating with a plurality of connector columns along a length of the stent;
- wherein each of the strut columns includes a plurality of interconnected struts extending circumferentially around a longitudinal axis of the stent, wherein the interconnected struts form alternating peaks and troughs;
- wherein the connector columns include a plurality of connector struts, wherein each of the connector struts includes a first axial segment coupled to a first peak of a first strut column, a second axial segment coupled to a first trough of a second strut column, and a circumferential segment extending in a single circumferential direction from the first axial segment to the second axial segment;
- and
- wherein the stent includes a first position having a first length and a second position having a second length, the second length being at least 20% greater than the first length;
- wherein the stent is configured to shift between the first length and the second length without a changing its diameter.

A tracheal stent, comprising:
- a plurality of strut columns alternating with a plurality of connector columns along a longitudinal axis of the stent;
- wherein each of the strut columns includes a plurality of interconnected struts extending circumferentially around a longitudinal axis of the stent, wherein the interconnected struts form alternating peaks and troughs;
- wherein the connector columns include a plurality of connector struts, and wherein each of the connector struts includes a first axial segment coupled to a first peak of a first strut column, a second axial segment coupled to a first trough of a second strut column, and a circumferential segment extending only in a first circumferential direction from the first axial segment to the second axial segment;
- wherein the first axial segment is circumferentially offset from the second axial segment;
- wherein the stent is configured to shift between a nominally deployed configuration in which the stent has a nominally deployed length and an axially extended configuration in which the stent has an axially extended length, wherein the axially extended length is at least 20% greater than the nominally deployed length;
- wherein the stent is configured to shift between an axially compressed configuration in which the stent has an axially compressed length to the axially extended configuration, wherein the axially compressed length is less than the nominally deployed length.

- wherein each circumferential segment within each connector column extends in only one circumferential direction from the first axial segment to the second axial segment;
- wherein the stent includes a first position having a first length and a second position having a second length, and a third position having a third length, the third length being at least 20% greater than the second length and the second length being greater than the first length;
- wherein the stent is configured to shift between the first length and the third length without a changing its diameter.
