1. A balloon catheter assembly comprising:
an intra-aortic balloon catheter comprising a proximal end, a distal end, and a tube arranged between the proximal end and the distal end, wherein the tube has an outer surface and an inner surface defining at least one lumen extending between the proximal end and the distal end, and a balloon membrane is disposed at the distal end; and
a sheath seal comprising an elastomeric housing comprising a proximal end, a distal end, a lumen of the sheath seal arranged between the proximal end of the housing and the distal end of the housing, wherein the housing comprises an impingement device, wherein the lumen of the sheath seal is configured to slidably receive the tube therein and the impingement device is configured to engage the outer surface of the tube and apply a force thereto in order to prevent the tube from sliding relative to the sheath seal when the impingement device is in a first state, and wherein the housing of the sheath seal further comprises one or more suture pads configured to permit passage of a suture therethrough to allow the sheath seal to be secured to a patient; and
a y-connection, comprising a y-connection hub having a proximal end, a distal end, and a lumen arranged between the proximal end and the distal end of the y-connection hub, wherein the y-connection hub is connected to the housing of the sheath seal.
