Abstract: An expandable introducer device includes an introducer hub and an introducer sheath coupled to the hub and extending distally therefrom. The introducer sheath includes a mesh tube, a liner disposed within the mesh tube, and an axial strip disposed between the mesh tube and the liner. The introducer sheath is radially-expandable from a first diameter to a second diameter larger than the first diameter in response to a device being advanced through the introducer sheath.

Abstract: An expandable introducer includes a hub and a tubular sheath (121) coupled thereto. The tubular sheath (121) defines a central lumen (103). A circumference of the tubular sheath includes a full thickness region (162) having a first wall thickness (T2) and a reduced thickness region (161) having a second wall thickness (T1) smaller than the first wall thickness (T2). The reduced thickness region (162) is configured to be folded such that the tubular sheath includes an unexpanded, folded state and is configured to expand to an expanded, unfolded state in response to a device passing though the central lumen (103). A first outer diameter of the tubular sheath in the unexpanded, folded state is smaller than a second outer diameter of the tubular sheath in the expanded, unfolded state.

Abstract: An advancer includes an advancer hub and an advancer shaft extending distally from the advancer hub. The advancer shaft includes a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The advancer shaft is configured to be disposed around an outer shaft of a delivery catheter, and includes a split line configured to enable splitting the shaft to enable removal of the shaft from the outer shaft. The advancer hub configured to be mounted on the outer shaft of the delivery catheter, and includes a parting line to enable splitting of the advancer hub.
