Balloon guiding sheath having a textured surface

A method comprising:

• inserting a balloon guiding sheath directly into vasculature of a patient through an arteriotomy, the balloon guiding sheath comprising:
• an elongated sheath comprising a proximal end, a distal end, an inner tube extending between the proximal end and the distal end, an outer tube surrounding the inner tube and extending between the proximal end and the distal end, an access port located adjacent the proximal end, a distal port located adjacent the distal end, and a working lumen extending through an interior portion of the elongated sheath between the access port and the distal port;
• an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end, the inflatable balloon being fluidly coupled to an inflation lumen via a plurality of inflation holes, the inflation lumen extending between the inflatable balloon and an inflation port located adjacent the proximal end;
• and
• a textured surface located along an outer portion of the outer tube and located between the inflatable balloon and the inflation lumen, wherein the textured surface defines a first area, and an inflatable portion of the inflatable balloon defines a second area, and wherein the second area is greater than the first area,
• wherein the plurality of inflation holes are located closer to a distal portion of the inflatable balloon than to a proximal portion of the inflatable balloon,
• wherein the textured surface is located closer to the distal portion of the inflatable balloon than to the proximal portion of the inflatable balloon, and
• wherein the plurality of inflation holes are longitudinally aligned with the textured surface;
• advancing the balloon guiding sheath through the vasculature of the patient and positioning the distal end at a target site;
• and
• inflating the inflatable balloon, wherein the textured surface and the plurality of inflation holes are arranged and configured to facilitate substantially radially symmetric inflation of the inflatable balloon.

A balloon guiding sheath, comprising:

• an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end, the inflatable balloon being fluidly coupled to an inflation lumen via a plurality of inflation holes, the inflation lumen extending between the inflatable balloon and an inflation port located adjacent the proximal end;
• and
• a textured surface located along an outer portion of the outer tube and located between the inflatable balloon and the inflation lumen, wherein the textured surface defines at least one raised surface and at least one lowered surface, and wherein the textured surface defines a first area and an inflatable portion of the inflatable balloon defines a second area greater than the first area,
• wherein the elongated sheath is sized and configured to enable direct insertion of the elongated sheath into a patient's vasculature through an arteriotomy to position the inflatable balloon at a target site, and
• wherein the plurality of inflation holes are located closer to a distal portion of the inflatable balloon than to a proximal portion of the inflatable balloon, wherein the plurality of inflation holes are longitudinally aligned with the textured surface, and wherein the textured surface and the plurality of inflation holes are arranged and configured to facilitate substantially radially symmetric inflation of the inflatable balloon.
