Heart Valves TRIZ Cases

Automated electrospinning replaces manual suturing, reducing tissue waste and manufacturing time for biocompatible valves.

Segmented annular augmentation device anchors mitral valve tissue to reduce regurgitation without impairing left ventricular outflow tract function.

Notched thread-like elements on an adjustable catheter self-center within irregular blood vessels, enabling precise guidewire placement without complex imaging.

A polymeric heart valve uses a semi-interpenetrating polymer network to enhance biocompatibility and durability.

An external BACE system uses fillable chambers to compress the heart base, reducing valve leakage without invasive surgery.

Orthogonal delivery orientation anchors the expandable frame securely to prevent regurgitation without open surgery.

A removable bioprosthetic heart valve holder with a maneuvering system aligns the valve frame to the abutment ring.

A delivery system tip transitions from a conical to a rounded profile via axial force.

An offset hole relocates the handle away from the center, preventing radial pushing that spreads the aorta and distorts commissure measurements.

Nested stent cells pivot to clamp native tissue, securing the valve without excessive radial force or high profile.

A collapsible support frame with a tapered upstream inlet converges toward the central axis to reduce compressed diameter.

Nested optical coherence tomography catheter enables precise leaflet capture assessment, reducing slippage risks in percutaneous valve repair.

Dual anchoring assemblies compress native biological tissue to secure a prosthetic heart valve without sutures.

Braided expandable member directs delivery tube to fossa ovalis, resolving alignment issues for large profile devices via superior vena cava.

A curved groove and pin mechanism guides valve movement to regulate blood flow through a vessel.

Jack screws actively expand the mitral valve lattice beyond its self-expanded shape, eliminating paravalvular leakage from fixed-diameter implants.

A mitral valve prosthesis uses invertible positioning elements to engage heart tissue for secure placement via percutaneous delivery.

An implantable sensor device transmits pressure data wirelessly, enabling continuous monitoring without invasive procedures.

Radially movable second cell structures in a medical valve implant adapt to asymmetric calcifications, reducing material load and extending service life.

Radial anti-migration spikes engage native tissue to prevent device migration while buffer nets reduce contact damage during deployment.

An elastically deformable insertion aperture member facilitates cardiac assist device deployment through a linear pericardial incision.

A laparoscopic deployment device uses flexible arms to reversibly transform from straight to curved configurations for controlled patch placement.

Dual lumens in the inner shaft anchor guidewires to pulmonary arteries, resisting unintended movement during valve expansion.
