Abstract: An overtube assembly for use with an elongate medical tool includes an overtube including a flexible tubular body having a proximal end and distal end. The flexible tubular body includes a split extending from the proximal end to the distal end. The overtube assembly further includes an inflatable balloon coupled to a distal portion of the flexible tubular body. The flexible tubular body is disposable over a section of the elongate medical tool by inserting the elongate medical tool through the split.

Abstract: Medical devices including balloons and balloons are provided that include an elongate body and an inflatable balloon defining a longitudinal axis, the inflatable balloon being attached to and partially surrounding at least a section of the elongate body. The medical device further includes a plurality of protrusions extending from the inflatable balloon. When the inflatable balloon is in an unstrained state, each of the plurality of protrusions extends in a first transverse direction relative to the longitudinal axis. In certain implementations, the inflatable balloon may also be configured to collapse such that, when in a collapsed state, an untextured portion of the inflatable balloon extends to a radius and the plurality of protrusions does not extend beyond the radius.
