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.

Abstract: An expandable introducer includes a hub and an introducer sheath extending distally from the hub. The introducer sheath includes a balloon having an interior surface defining a central lumen of the introducer sheath, an exterior surface, and an inner area between the interior surface and the exterior surface. The introducer sheath includes a folded configuration and an unfolded configuration. The introducer sheath is configured to be advanced into a vessel of a patient in the folded configuration. The balloon may be partially inflated prior to advancement of a delivery device through the introducer sheath such that the delivery device displaces inflation fluid in the partially inflated balloon. The introducer sheath may be unfolded by inflation of the balloon or by advancement of the delivery device through the introducer sheath. The balloon is configured to be fully inflated prior to retraction of the delivery device through the introducer sheath.

Abstract: A system for delivering an implantable medical device to an implant location includes a control handle portion, a catheter portion coupled to the control handle portion, and a distal portion configured to receive the implantable medical device. The catheter portion includes outer shaft including an inner braided layer extending axially along the outer shaft, an outer braided layer extending axially along the outer shaft, wherein the outer braided layer has a lower density of braids relative to the inner braided layer, and an axial spine positioned between the inner braided layer and the outer braided layer extending axially along the outer shaft.
