Abstract: A delivery system for delivering an implantable heart valve includes an outer shaft and an inner shaft that is slidingly disposable within an outer shaft lumen, the inner shaft including a distal end region. A plurality of fingers extend distally relative to the distal end region of the inner shaft and are adapted to releasably engage an implantable heart valve. A plurality of looped sheathing aids extend distally from the distal region of an inner shaft lumen and are adapted to guide the implantable heart valve back into the outer shaft lumen when the implantable heart valve is pulled back into the outer shaft lumen. Each of the plurality of looped sheathing aids include a distal petal adapted to engage tissue adjacent a native valve annulus in order to limit distal advancement of the implantable heart valve during deployment of the implantable heart valve.

Abstract: A medical device handle may include a handle housing including a cavity disposed within the handle housing. The medical device handle may include a carriage assembly disposed within the cavity and operatively connected to the tubular member and the medical implant, the carriage assembly being longitudinally movable between a distal position and a proximal position by rotation of a control knob with respect to the handle housing, the control knob being disposed around a proximal end of the handle housing. The carriage assembly may include a carriage member, a first sliding member, a second sliding member, and a locking element configured to releasably fix the first sliding member and the second sliding member relative to the carriage member. The locking element may be rotatable relative to the handle housing.

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 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: An example introducer is disclosed. An example introducer includes an inner liner including a lumen, a distal region and at least one folded portion extending along the distal region. The introducer also includes a reinforcing member having a length and including at least one spine extending along the length of the reinforcing member. The introducer also includes a sheath disposed along at least a portion of the introducer, wherein the sheath includes at least one perforation, wherein material adjacent to the at least one folded portion is removed from a distal portion of the introducer to form a tip region. The introducer also includes a tip member disposed along the tip region.

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.
