The present invention relates to a handle assembly () for an implant delivery device for folding or unfolding at least one medical implant by means of at least one tension thread, wherein the handle assembly () comprises a drum () for winding the tension thread thereon by rotating the drum (); a knob () to be rotated by a user of the handle assembly () in order to fold or unfold the medical implant, the knob () being interconnected with the drum () such that the drum () is rotated when the knob () is rotated; and a displacement limiter for limiting the length or displacement by which the tension thread () may be at least one of wound onto or unwound from the drum () by rotating the knob ().

Handle assembly for implant delivery apparatus comprising a force limiter, a displacement limiter and/or a brake frame assembly

The present invention relates to a handle assembly () for an implant delivery device for folding or unfolding at least one medical implant by means of at least one tension thread, wherein the handle assembly () comprises a drum () for winding the tension thread thereon by rotating the drum (); a knob () to be rotated by a user of the handle assembly () in order to fold or unfold the medical implant by tightening or winding the tension thread or by releasing or unwinding the tension thread, the knob () being arranged or interconnected with the drum () such that the drum () may be rotated when the knob () is rotated; and a brake frame assembly () comprising at least one brake element and at least one spring () arranged to act on the brake element such that the brake elements contact one surface of the rear knob ().

A collapsible-expandable tubular stent () constructed of shape-memory material which is implantable into a human heart, which comprises proximal and distal rings () and at least two spaced apart posts () that extend axially between said rings (), said distal ring () comprising a plurality of distal arms () which are connected to the distal ring () at only one end and which have a free opposite end; said proximal ring () comprising a plurality of, which are connected at only one end to the proximal ring () and which have a free opposite end, which proximal arms () are constructed to swing radially outward at their free ends.

Minimally invasive mitral valve replacement with brim

The present invention relates to a handle assembly () for an implant delivery device for folding or unfolding at least one medical implant by means of at least one tension thread, wherein the handle assembly () comprises a drum () for winding the tension thread thereon by rotating the drum (); a knob () to be rotated by a user of the handle assembly () in order to fold or unfold the medical implant, the knob () being interconnected with the drum () such that the drum () is rotated when the knob () is rotated; and a force limiter for limiting the maximum force or tension that may be applied or is applicable to the tension thread () or to the drum () by rotating the knob ().
