    Abstract: An apparatus may include a medical device including an elongate shaft disposed about a guidewire, and a distal tip including a plurality of rounded protrusions, wherein adjacent protrusions are fixed directly to each other by a relatively flexible connector. The plurality of protrusions may decrease in size from a proximalmost protrusion distally to distalmost protrusion.

    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 apparatus may include a medical device including an elongate shaft disposed about a guidewire, and a distal tip including a plurality of rounded protrusions, wherein adjacent protrusions are fixed directly to each other by a discrete, relatively flexible connector. The plurality of protrusions may each decrease in size from a proximalmost protrusion distally to distalmost protrusion.
