Heart Valves TRIZ Cases

A delivery catheter handle system enables controlled micro and macro movements of a distal sheath for precise prosthetic valve deployment.

Pivoting cantilevered fixation members clamp native leaflets to secure a prosthetic valve assembly.

Segmented helical coils provide controlled deployment and precise positioning of prosthetic heart valves while minimizing backfolding risks.

A medical device wall features spaced protuberances that generate micro-vortices to modify fluid flow patterns.

A self-expanding wire framework flares outwardly to encircle the heart using elastic memory and articulated joints.

Snap-fit mechanical coupling connects central body to connecting blocks in transcatheter heart valve prostheses.

Segmented sheath fins distribute radial pressure evenly to minimize vessel trauma and reduce procedural time.

A heart stabilizer uses integrated aspiration channels within bearing elements to remove fluids during surgery.

An annulus support with radial tabs engages the native mitral annulus to prevent migration, resolving positioning difficulties in minimally invasive procedures.

Segmented stabilizing ring expands radially at predetermined points to accommodate new prostheses without reducing flow cross-section.

Piezochromatic indicators change color under force to provide visual feedback, preventing device reuse and identifying counterfeit products.

A braided introducer sheath with elastomeric covering expands via nested struts to accommodate large prosthetic heart valves while minimizing vascular trauma.

Biased arms in a mitral valve fixation device grasp leaflets to reduce regurgitation while a spreader manages deployment complexity.

A stop on the elongate body restricts capsule movement during deployment, preventing disengagement and anatomy interference.

Guide slots and sliding pins enable closure members to extend beyond the clamp body, resolving limited capturing distance in narrow channels.
