Abstract: A delivery device for cardiac valve repair implants includes a delivery catheter and an extension member protruding from a distal end of the delivery catheter. The delivery device further includes a control arm assembly having pairs of control arms. Each pair includes a proximal control arm drivable from a handle assembly of the delivery device and a distal arm coupled to a distal end of the proximal control arm and a distal end of the extension member. Proximally driving each of the proximal control arms of the control arm assembly results in expansion of the control arm assembly and corresponding expansion of a cardiac valve repair implant coupled to the control arm assembly.

Abstract: An athletic shoe is disclosed having a two component traction system. The traction system includes an upper and an outsole. The outsole is coupled to the upper. The outsole includes at least a first traction portion and a second traction portion. Each of the first traction portion and the second traction portion define a portion of a bottom surface of the shoe. The first traction portion includes a plurality of first traction elements that provide the shoe with first traction characteristics. The second traction portion comprises a plurality of second traction elements that differ from the first traction elements in size, shape or density and provide the shoe with second traction characteristics different from the first traction characteristics. At least one of the first traction portion and the second traction portion is replaceable.
