Stent delivery systems with a reinforced deployment sheath
Stent delivery systems and methods for making and using the same are disclosed. An example stent delivery system may include an inner member. A deployment sheath may be disposed about the inner member. A stent may be disposed between the inner member and the deployment sheath. The deployment sheath may include a translucent reinforcing member that allows for visualization of the stent during stent deployment.
1. A stent delivery system, comprising:
an inner member;
a deployment sheath disposed about the inner member, wherein at least a distal region of the deployment sheath is translucent;
a stent disposed between the inner member and the deployment sheath; and
a translucent reinforcing member disposed within the translucent distal region of the deployment sheath, wherein the translucent reinforcing member and the translucent distal region of the deployment sheath allow for visualization of the stent during stent deployment.
2. The stent delivery system of claim 1 , wherein the stent includes a self-expanding stent.
3. The stent delivery system of claim 1 , wherein the translucent reinforcing member includes a braid.
4. The stent delivery system of claim 1 , wherein the translucent reinforcing member includes a coil.
5. The stent delivery system of claim 1 , wherein the translucent reinforcing member includes a polymer.
6. The stent delivery system of claim 1 , wherein the translucent reinforcing member includes polyetheretherketone.
7. The stent delivery system of claim 1 , wherein the deployment sheath extends from a proximal end of the deployment sheath to a distal end of the deployment sheath.
8. The stent delivery system of claim 1 , wherein the deployment sheath has a proximal region, and wherein the translucent reinforcing member extends along the translucent distal region.
9. The stent delivery system of claim 8 , wherein the translucent distal region has an enlarged outer diameter relative to the proximal region, an enlarged inner diameter relative to the proximal region, or both.
10. The stent delivery system of claim 1 , wherein the deployment sheath includes an inner liner and an outer layer, and wherein at least a portion of the translucent reinforcing member is disposed between the inner liner and the outer layer.
11. The stent delivery system of claim 10 , wherein the inner liner, the outer layer, or both are at least partially translucent.
12. The stent delivery system of claim 1 , further comprising a handle coupled to the inner member and to the deployment sheath, the handle including an actuation member capable of translating the deployment sheath relative to the inner member.
13. A stent delivery system for use along a biliary tract, an enteral tract, or an airway, the stent delivery system comprising:
an inner member;
a deployment sheath disposed about the inner member;
a self-expanding stent disposed between the inner member and the deployment sheath; and
wherein the deployment sheath includes an inner liner, an outer layer, and a translucent braided reinforcing member disposed at least partially between the inner liner and the outer layer;
wherein the inner liner and the outer layer are translucent; and
wherein the inner liner, the outer layer, and the translucent braided reinforcing member allow for visualization of the self-expanding stent during stent deployment.
14. The stent delivery system of claim 13 , wherein the translucent braided reinforcing member includes a polymer.
15. The stent delivery system of claim 13 , wherein the translucent braided reinforcing member includes polyetheretherketone.
16. The stent delivery system of claim 13 , wherein the deployment sheath has a proximal region and a distal region, and wherein the translucent braided reinforcing member extends along at least the distal region.
17. The stent delivery system of claim 16 , wherein the distal region has an enlarged outer diameter relative to the proximal region, an enlarged inner diameter relative to the proximal region, or both.
