FEATURES TO ENHANCE GRIP OF BALLOON WITHIN AIRWAY

摘要

A dilation assembly includes a shaft and a dilator coupled with the distal end of the shaft. The dilator includes a proximal end, a distal end, and a center portion positioned between the proximal end and the distal end. The center portion dilates from a first configuration to a second configuration. The center portion has a larger diameter than the proximal end and the distal end when the center portion is in the second configuration. At least one gripping feature is positioned on at least a portion of the exterior surface of the center portion. The gripping feature provides friction between the center portion and a bodily lumen when the center portion is in the second configuration.

1. A dilation assembly, wherein the dilation assembly comprises:
(a) a shaft, comprising a distal end and a proximal end; and (b) a dilator coupled with the distal end of the shaft, wherein the dilator comprises:
(i) a proximal end,(ii) a distal end,(iii) a center portion positioned between the proximal end and the distal end, wherein the center portion is dilatable to have a larger diameter than the proximal end and the distal end, wherein the center portion is configured to dilate from a first configuration to a second configuration, and(iv) at least one gripping feature positioned on at least a portion of an exterior surface of the center portion, wherein the gripping feature is configured to provide friction between the center portion of the dilator and a bodily lumen when the center portion is in the second configuration.
