Indications for Use
TriMemo is indicated for use in patients suffering from congenital or acquired tricuspid insufficiencies or steno-insufficiencies with dilatation and/or deformation of the tricuspid annulus.
Device Story
TriMemo is a semirigid annuloplasty ring designed to restore tricuspid valve leaflet coaptation and function by reshaping the tricuspid annulus. The device features an electropolished Nitinol core embedded in a silicone sewing ring covered with polyester (PET) fabric, treated with a Carbofilm™ (turbostratic carbon) coating. It has an open 3D shape with modular flexibility, providing higher stiffness in the posterior portion to address dilated valve walls, while remaining flexible at the ends to avoid heart conduction system interference. The ring is implanted by a surgeon during cardiac procedures. It includes visual markers for positioning and suturing. By stabilizing the annulus, the device prevents further dilation and improves leaflet coaptation. It is supplied sterile for single-use.
Clinical Evidence
No clinical data. Evidence is based on bench testing, including Finite Element Method (FEM) analysis, mechanical strength testing, suture pull-out tests, fatigue testing (400 million cycles), MRI compatibility, and usability summative evaluation. Sterilization and packaging validation were also performed.

## Device Description Summary
TriMemo™ is a semirigid annuloplasty ring intended to restore the proper tricuspid valve leaflet coaptation and valve function by reshaping the tricuspid annulus.
The TriMemo consists of an inner electropolished Nitinol core embedded in a sewing ring of silicone and knitted with polyester (PET) fabric. The fabric is coated with Carbofilm™ coating, a thin layer of turbostratic carbon. The ring has an open 3D shape and modular flexibility which adapt to the annulus tridimensional anatomy and movements, with the highest stiffness in the posterior portion, that gradually decreases toward the anterior and septal ends. The cuff has a white guideline to identify the suturable portion, two commissural markers for the correct positioning in the annulus and two markers close to the open ends, that indicate the end of the suturable portion.
TriMemo is available in 6 sizes of increasing dimension starting from size 26 to size 36 with 2 mm steps. The device is supplied as a sterile (steam sterilization) and non-pyrogenic ring, for single-use only.
TriMemo exhibits a modular flexibility to comply with the three-dimensional annulus motion. The ring is stiffer in the posterior portion corresponding to the native valve dilated wall, and gradually flexible towards the ends that are open to avoid interference with the heart conduction system.

The core stiffness is calculated through a Finite Element Method and varies between the core posterior portion (rigid) and the two core ends (flexible), slightly increasing with the core size.
The ring mechanical strength in-plane and out-of-plane, and the suture pull-out test guarantee resistance to loading conditions higher than 3 times those occurring under in-vivo conditions. The TriMemo expected lifetime under continued function is at least 400 million cycles corresponding to a 10-year implant lifetime. In clinical use the device lifetime is affected by many patient factors and thus a definitive expected lifetime cannot be assured.
TriMemo shows high visibility through imaging techniques, for the whole device length.
# Intended Use/Indications for Use
TriMemo is indicated for use in patients suffering from congenital or acquired tricuspid insufficiencies or steno-insufficiencies with dilatation and/or deformation of the tricuspid annulus.

| --- | --- | --- |
| TriMemo is indicated for use in patients suffering from congenital or acquired tricuspid insufficiencies or stenoinsufficiencies with dilatation and/or deformation of the tricuspid annulus. | The Carpentier-Edwards Physio Tricuspid annuloplasty ring, model 6200, is intended for use in patients with tricuspid valvular insufficiency. It is intended to correct annular dilatation, increase leaflet coaptation, reinforce annular suture lines, and prevent further dilatation of the annulus. | Both devices are indicated for patients with tricuspid valvular insufficiency; the additional information on “congenital or acquired” insufficiency included in TriMemo is only meant to specify that both types of insufficiencies are included. The “stenoinsufficiencies” included in TriMemo is a type of insufficiency (where patients affected by insufficiency have also a partial stenosis of the valve). Therefore, the generic indication “insufficiency” in the Physio IFU also includes the indication for patient with stenoinsufficiencies: the aim of both rings is to correct the insufficiency of the tricuspid valve. No substantive differences are identified; differences are merely in wording, which do not alter the substantial equivalence of the indications for use statements |

Based on the comparison table above, the indications for use statement for TriMemo are substantially equivalent to those of the predicate device.
## Technological Comparison
The analysis conducted regarding TriMemo and Physio technological characteristics has considered:
- Design: both are open semi-rigid open rings
- Materials: both have metallic cores covered with polyester cloth.
- Both rings are supplied sterile (steam sterilized) and non-pyrogenic, for single-use only.
- Both rings are provided on a holder, in a double-sealed packaging.
- Both rings have a 5-years shelf life
- The accessories used for allowing implantation are sizers, corresponding to each ring size, and a handle(s for TriMemo device) provided non-sterile. The accessories are packaged separately, provided non-sterile and must be cleaned and sterilized before each use.
However, some technological differences have been identified:
- Slight design and shape differences - not raising different questions of safety and effectiveness, TriMemo design is based on other implantable medical devices and it is not an innovative one;
- Materials - even if the overall characteristics of device and packaging materials are the same, the existing differences do not raise any new questions of safety and effectiveness since TriMemo materials are already commonly used for Annuloplasty rings and they are not innovative materials.
Corcym decided to use Memo 4D Semirigid Annuloplasty Ring (K230318) as Reference device, for supporting the appropriate scientific methods used for characterizing the new device, based on similarities in terms of design, materials, packaging and manufacturing process.
The testing on TriMemo, performed according to FDA guidance and recognized standards, evaluated substantial equivalence to the predicate.
## Non-Clinical and/or Clinical Tests Summary & Conclusions
Based on the differences between TriMemo and the Predicate and Reference Devices, the following nonclinical Performance tests were specifically performed on TriMemo device confirming that there are substantially equivalent safety and effectiveness outcomes:
- Computational stress/strain Analysis as per FDA "Guidance for Annuloplasty Rings 510(k) Submissions" and "Technical Considerations for Non-Clinical Assessment of Medical Devices Containing Nitinol" following ISO 5910 and ASME V&V 40-2018;
- Verifications of mechanical characteristics of the device as per FDA "Guidance for Annuloplasty Rings 510(k) Submissions" and mechanical characterization of the PET fabric;

WE TAKE LIFE TO HEART
- Suture pull-out test as per FDA "Guidance for Annuloplasty Rings 510(k) Submissions";
- Fatigue testing as per FDA Guidance "Technical Considerations for Non-Clinical Assessment of Medical Devices Containing Nitinol" following ISO 5910
- MRI compatibility testing, following "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" and technical standards ASTM F2052-21, ASTM F2213-17, ASTM F2182-19e2, ASTM F2119-24, ASTM F2503-23e1;
- Usability Summative evaluation, following FDA Guidance "Applying Human Factors and Usability Engineering to Medical Devices".
## Additionally:
- sterilization validation was performed according to appropriate FDA guidances ("Guidance for Annuloplasty Rings 510(k) Submissions", "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submissions for Devices Labeled as Sterile") and technical standards ISO 17665:2024, ISO-11138-1:2017, ISO-11138-3:2017, ISO 11737-2:2019, USP current ed. <71>, ANSI/AAMI ST72:2019, USP current ed. <161>, USP current ed. <85>;
- packaging validation was performed at $t=0$ (after environmental conditioning as per ASTM D4332:2022 and simulated distribution as per ASTM D4169:2024 - revision 2024 not FDA recognized) and after 5 years of accelerated ageing (ASTM F1980:2016(R2021)) by visually inspecting the devices as per ASTM F1886/F1886M:2016(R2024) and testing testing the sterile barrier integrity by seal strenght (ASTM F88 /F88M:2023) and bubble leak (ASTM F2096:2011(R2019)).
As results of the nonclinical tests performed, TriMemo has proven to withstand loading condition 3 times higher than those occurred under in-vivo conditions without any damages or ring shape alterations; the suture retention test was passed since all samples shown a value above the acceptance criteria; the device maintains its structural integrity for a minimum of 400 million cycles under simulated physiological flow, passed all non-clinical testing for hazards in MRI environment and the summative user evaluation. Based on the outcome of performance testing and validation conducted, TriMemo Semirigid Annuloplasty Ring is considered to be substantially equivalent to the predicate device, since they have the same intended use; the technological differences - supported by the reference device and the tests conducted - do not raise different questions of safety and effectiveness.
