摘要： Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a helical scroll slidable configuration. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during the application of a radial outward force by passage of a medical device through the sheath.

摘要： An expandable sheath including an elongated inner member defining a central lumen extending therethrough. The inner member includes a first circumferential portion including a first and second longitudinal edges, and a second circumferential portion extending between the first and second longitudinal edges. The wall thickness of the first circumferential portion is greater than the wall thickness of the second circumferential portion. The elongated inner member is configured to transition from an unexpanded configuration to an expanded configuration in response to a radially outward force on an inner surface of the central lumen. In the unexpanded configuration, the elongated inner member is creased proximate the first and second longitudinal edges into a folded configuration such that the second circumferential portion is positioned at least partially radially inward of the first circumferential portion.

摘要： The present disclosure generally relates to systems, devices, and methods for delivery systems including deflectable elongate shafts. A delivery system may include a deflectable elongate shaft including a pull tether extending along the length of the elongate shaft and having a distal portion and a proximal portion and an intermediate portion, with the distal portion of the pull tether coupled to a portion of the elongate shaft such that the intermediate portion of the pull tether may variably move towards the first set of bi-directional cuts or the second set of bi-directional cuts. The pull tether may be configured to be pulled to deflect the hypotube.

摘要： The expandable sheaths disclosed herein include an expandable outer layer and a generally non-expandable inner layer. The outer layer is movable between a non-expanded configuration and an expanded configuration, where the outer layer/tubular layer is biased to the non-expanded configuration. Receipt of the inner layer within the central lumen of the outer layer causes the outer layer to transition from the non-expanded configuration to the expanded configuration.

摘要： The expandable sheaths disclosed herein are adapted to be used in tortuous vessels, such as, but not limited to, the subclavian artery. The sheaths are expandable to facilitate passage of a medical device through a central lumen of the sheath. The sheaths can be used to deliver medical devices, such as implantable heart valves. The methods of delivering a medical device can include transforming a distal region of the expandable sheath to an at least partially bowed configuration and bending a central shaft of the expandable sheath around a bend in vasculature without kinking the sheath.

摘要： Examples of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such examples can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some examples can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some examples include an elastic outer cover positioned outside the outer layer. Examples of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

摘要： Various systems, devices, and methods are described herein pertaining to expandable sheaths. Sheath aspects are described that include a flexible sheath tip that is expandable and bendable. In some aspects, the sheath includes a radially expandable proximal end and a radially expandable distal end. In some aspects, the sheath tip includes a plurality of layers that expand to accept a medical device traveling axially and bi-directionally therethrough with minimal deformation of the sheath tip.

摘要： A sheath locking system comprising an introducer locking hub comprising a hub body defining a locking channel for engaging a corresponding guide on a sheath locking sleeve. The sheath locking sleeve removably coupled to the introducer locking hub via engagement between the guide and the locking channel. The sheath locking sleeve movable between an unlocked position where the sheath locking sleeve is rotationally and axially movable with respect to the introducer locking hub, and a locked position where the sheath locking sleeve is axially fixed with respect to the introducer locking hub.

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a variable diameter inner liner wound in a spiral slidable configuration and an outer layer. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath.
