1. A medical device comprising:
a catheter configured to be navigated through vasculature of a patient, the catheter comprising a distal portion and a proximal portion;
an expandable balloon that is attached to the distal portion of the catheter;
a tubular sheath comprising a proximal end and a distal end,
wherein the tubular sheath defines a groove extending longitudinally from the proximal end to the distal end, the groove configured to split the tubular sheath from the proximal end to the distal end in response to application of a force above a threshold force,
wherein the tubular sheath defines a radius from a longitudinal axis of the tubular sheath, and
wherein the tubular sheath is configured to separate from the catheter in a radial direction defined by the radius when the groove splits the tubular sheath from the proximal end to the distal end; and
an introducer sheath configured to be inserted into the vasculature,
wherein the introducer sheath is configured to allow the expandable balloon and the catheter to pass through the introducer sheath and stop the tubular sheath from passing through the introducer sheath, and wherein at least one of:
the introducer sheath is configured to threadably engage the tubular sheath,
the introducer sheath defines a proximal internal diameter configured to allow the tubular sheath to insert distal to the proximal internal diameter and defines a distal internal diameter distal to and less than the proximal internal diameter, wherein the distal internal diameter is configured to prevent the tubular sheath from inserting distal to the distal internal diameter, or
the tubular sheath defines a distal inner diameter configured to allow the introducer sheath to insert proximally into an inner lumen defined by the tubular sheath and defines a proximal inner diameter proximal to and less than the distal inner diameter, wherein the proximal inner diameter is configured to prevent the introducer sheath from inserting within the tubular sheath proximal to the proximal inner diameter.
