Concept render of the Schwartz™ Wire: a smooth bright-green shaft rising out of a slim lavender sheath into one large arch, a short steel band, then a sage-green coil-wound section ending in a large egg-shaped open spiral with a small inner curl

Schwartz™ Wire · TAVR guidewire · Prototype · Patent pending

Strong rail support, designed for gentle
apical contact.

Its preshaped curve is designed to absorb force at the aortic arch, so less force travels down the wire and the spiral tip can rest atraumatically at the apex.

01 — The tradeoff

The stiff-wire tradeoff.

Now, the Schwartz™ Wire.

AorticarchAscending aortaDescending aorta
  1. 01The wire runs over the aortic arch and parks in the LV, ready to support the delivery system.
  2. 02The delivery system advances. The rail takes the load.
  3. 03A conventional wire turns at one point on the arch, so load can concentrate there and at the apex.

02 — The design answer

Designed to distribute the load across the arch.

Now, the Schwartz™ Wire.

AorticarchAscending aortaDescending aorta
  1. 01The large curve is designed to sit atop the aortic arch, adding stability to the rail.
  2. 02The delivery system advances. The arch curve is designed to absorb the push before it reaches the ventricle.
  3. 03With less force passed down the wire, the spiral tip is designed to rest atraumatically at the apex.

From the arch to the apex.

Watch the Schwartz™ Wire take its intended position: over the aortic arch, through the valve, and into a spiral tip in the left ventricle.

04 — Design goals

Can a wire provide rigidity, offer stability, and be gentle at the same time?

Six design goals,
one system.

Six things the Schwartz™ Wire is engineered to do.

01 · Platform

Rail support for delivery

A stiff, stable rail designed to support bulky delivery systems across the arch, native valve and annulus, including tortuous or calcified anatomy. Stiffness is designed to sit in an optimal balance with atraumatic anchoring.

02 · Stability

Positional stability

Designed to hold its shape in the LV through advancement, positioning, deployment and recapture, so the wire stays where it was placed.

03 · Anchoring

Atraumatic anchoring

The spiral tip is designed to compress under low force, so it can anchor in the ventricle atraumatically. Paired with a stiff rail, it is designed for an optimal balance of rigidity and soft anchoring.

04 · Arch

Force absorbed at the arch

The preshaped curve is designed to ride the outer aortic arch and absorb the push of the delivery system there, so less force passes down the wire.

05 · Apex

Gentle apical contact

With less force passed down the wire, the spiral tip is designed to rest atraumatically at the apex, without concentrating stress on the ventricular wall.

Concept renderings. Not the final device.
06 · Movement

Forward movement at the arch

If the delivery system moves forward unexpectedly, the arch curve is designed to absorb that force, so less of it reaches the myocardium.
