1. An intravascular delivery system comprising:
an outer member defining a sheath lumen, wherein the outer member comprises an outer member proximal end and an outer member distal end, wherein the outer member proximal end comprises an elongate mouth, wherein the elongate mouth extends along a diagonal,
wherein the outer member further comprises a proximal split ring positioned near the elongate mouth, wherein the proximal split ring extends along the diagonal of the elongate mouth,
wherein the outer member comprises a distal split ring and a solid distal ring, wherein the distal split ring is positioned between the proximal split ring and the solid distal ring, wherein a space is formed between the distal split ring and the solid distal ring,
wherein the outer member further comprises a plurality of openings, wherein the plurality of openings are positioned between the proximal split ring and the distal split ring; and
an inner member, wherein the inner member is configured to be disposed at least partially within the sheath lumen of the outer member, wherein the inner member comprises a delivery catheter configured to extend from the outer member distal end,
wherein the inner member comprises an engagement member, wherein the engagement member is configured to be guided by the elongate mouth and the proximal split ring into the sheath lumen of the outer member and toward the distal split ring,
wherein the engagement member is configured to expand the distal split ring as the engagement member passes through the distal split ring, wherein the engagement member is configured to be disposed in the space formed between the distal split ring and the solid distal ring, wherein the inner member and the outer member are engaged for a controllable common displacement when the engagement member is disposed in the space formed between the distal split ring and the solid distal ring.
