Abstract: A replacement heart valve commissure assembly may include a locking mechanism including a first locking portion spaced apart from a second locking portion in a delivery configuration and configured to engage with the second locking portion in a deployed configuration, wherein the first locking portion is longitudinally actuatable relative to the second locking portion between the delivery and deployed configurations. The commissure assembly may include a first valve leaflet and a second valve leaflet each secured to the first locking portion. A first sleeve portion of the first valve leaflet may be fixedly attached to a first fabric sleeve wrapped around a first leg of the first locking portion by a first filament, and a second sleeve portion of the second valve leaflet may be fixedly attached to a second fabric sleeve wrapped around a second leg of the first locking portion by a second filament.

Abstract: A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve.

Abstract: A containment vessel for storing and rinsing a medical implant coupled to a delivery system having an outer sheath may include a hollow element having a wall, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the lumen of the hollow element being configured and adapted to contain a medical implant in a partially-deployed configuration during storage and rinsing of the medical implant and a proximal end cap including a secondary proximal end cap removably secured to the proximal end cap and configured to reversibly seal the proximal end cap to the outer sheath, thereby establishing a closed fluid connection between the lumen of the hollow element and a lumen of the outer sheath. The proximal end cap may include a sheathing guide configured and adapted to direct the medical implant into the lumen of the outer sheath.

Abstract: A medical device apparatus may include a medical implant including a braided anchor member configured to actuate between a delivery configuration and a deployed configuration operatively connected to a delivery system. The delivery system may include a handle, an outer sheath extending distally from the handle, and an inner catheter disposed within the outer sheath. A sheathing aid may connect the delivery system to the medical implant, the sheathing aid being configured to guide the medical implant into the outer sheath upon relative closing movement therebetween. The sheathing aid may include a plurality of arms extending from the inner catheter to a proximal end of the braided anchor member. At least one arm of the plurality of arms may comprise a core member having a width and a flexible member positioned about the core member.

Abstract: An expandable sheath may include an inelastic compliant membrane having a lumen therethrough, and a discontinuous outer member bonded to the membrane. The membrane may include one or more folds formed therein. At least a portion of the outer member may extend continuously around a circumference of the membrane in a first configuration. The outer member may be configured to separate to a second configuration when subjected to a radially outward force from within the membrane. The outer member may taper from a first diameter adjacent a proximal hub to a second smaller diameter at a distal end. A method of manufacturing an expandable sheath may include forming one or more folds in a compliant membrane, cutting a plurality of apertures through a wall of an outer covering; and laminating the outer covering onto the membrane, wherein the plurality of apertures is disposed over the one or more folds.
