Loading basket for a stent delivery system

摘要

A loading basket is secured at its proximal end to a portion of a delivery device. The stent engages with the interior of the stent basket when loaded onto the delivery device to prevent shifting or movement of the stent during delivery of the stent to a desired location within the bodily lumen. In at least one embodiment, the loading basket has a proximal end, a distal end, and a braided surface. The loading basket comprises a proximal end portion, a proximal transition portion, a body portion, a distal transition portion, a distal end portion, and an angled inward distal end. When loaded onto the delivery device, the outer surface of the stent contacts at least the angled inward distal end of the delivery device and movement of the stent is prevented.

主权项

1. An expandable stent loading basket, the basket having a proximal end, a distal end, and a surface, the basket comprising:
a proximal end portion at the proximal end, the proximal end portion having a diameter; a proximal body portion connected to the proximal end portion, the proximal body portion having a diameter; a distal transition portion connected to the proximal body portion; a distal body portion connected to the distal transition portion, the distal body portion having a diameter; a gripper region between the distal transition portion and the distal body portion, the gripper region having a diameter smaller than the diameter of the distal body portion and smaller than a diameter of the distal transition portion; and a distal end portion connected to the distal body portion and forming the distal end of the basket, wherein the distal end portion has a diameter that tapers from a diameter of the distal body portion to a diameter at the distal end of the basket, wherein the diameter at the distal end is less than the diameter of the distal body portion, the diameter at the distal end is greater than the diameter of the proximal end portion, the diameter of the proximal body portion is greater than the diameter of the distal body portion, and the diameter of the distal body portion is greater than the diameter of the proximal end portion; wherein the basket is expandable from a radially compressed configuration to a radially expanded configuration.
