摘要：
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.
