Intended Use

The TandemHeart Transseptal Cannula Set-EF 72 is intended for Transseptal catheterization of the left atrium via the femoral vein for the purpose of providing a means for temporary (six hours or less) left ventricular bypass when connected to the TandemHeart extracorporeal blood pump which returns blood to the patient via the femoral artery or other appropriate site.

Device Story

The TandemHeart Transseptal Cannula Set-EF 72 is a medical device used for temporary left ventricular bypass. It consists of a 21 Fr transseptal cannula, a 14 Fr obturator, and a 14/21 Fr two-stage dilator. The device is inserted via the femoral vein to provide drainage of the left atrium. It connects to the TandemHeart extracorporeal blood pump, which returns blood to the patient via the femoral artery or another appropriate site. The cannula features radiopaque marker discs at the tip for visualization under fluoroscopy and includes suture rings for secure placement. It is intended for use by clinicians in a hospital setting for procedures lasting six hours or less. The device facilitates blood flow for circulatory support, benefiting patients requiring temporary mechanical assistance.

Clinical Evidence

Bench testing only. Testing included flow vs. pressure drop (HQ) verification, suture ring performance, mechanical integrity of radiopaque marker disc encapsulation, and hemolysis testing. Results demonstrated that the device's performance after six hours of use is consistent with its design and substantially equivalent to the predicate devices.

Technological Characteristics

The device is a 21 Fr transseptal cannula set including a 14 Fr obturator and 14/21 Fr dilator. It features encapsulated radiopaque marker discs at the tip for fluoroscopic visualization and includes suture rings. The device is 10 cm longer than the predicate. It is a passive mechanical device used for extracorporeal blood flow. No software, electronics, or energy sources are involved.

Indications for Use

Indicated for patients requiring temporary (≤6 hours) left ventricular bypass via transseptal catheterization of the left atrium through the femoral vein, connected to the TandemHeart extracorporeal blood pump.

Regulatory Classification

Identification

A cardiopulmonary bypass vascular catheter, cannula, or tubing is a device used in cardiopulmonary surgery to cannulate the vessels, perfuse the coronary arteries, and to interconnect the catheters and cannulas with an oxygenator. The device includes accessory bypass equipment.

#### Device

Trade/Proprietary Name: CardiacAssist TandemHeart Transseptal Cannula Set-EF 72 Common Name: Enhanced Flow Transseptal Cannula, 72 cm Classification Name: Cardiopulmonary bypass vascular catheter, cannula, or tubing

#### Predicate Devices

#### Intended Use

The TandemHeart Transseptal Cannula Set-EF 72 is intended for Transseptal catheterization of the left atrium via the femoral vein for the purpose of providing a means for temporary (six hours or less) left ventricular bypass when connected to the TandemHeart extracorporeal blood pump which returns blood to the patient via the femoral artery or other appropriate site.

#### Comparison of Technological Characteristics

The Transseptal Cannula Set-EF 72 is identical in construction to the predicate Transseptal Cannula Set-EF, with the exception that it is 10 cm longer in length. The increase in length results in a slightly higher pressure drop in the cannula. The Transseptal Cannula Set-EF 72 also contains suture rings in a separate sterile pouch, which are manufactured from the same material used to make the suture wings in the predicate Transseptal Cannula Set-EF. These rings are identical to those in the predicate CardiacAssist Transseptal Cannula set that was cleared under K030398. The Transseptal Cannula Set-EF 72 also has encapsulated Radiopaque Marker discs at the cannula tip for clear visualization under fluoroscopy. These markers are identical to those utilized in the predicate BioMedicus Pediatric Femoral Venous Cannula that was cleared per K872033.

#### Performance Data

A risk assessment was conducted to determine the impact of the changes and the appropriate testing to perform. Subsequently, testing of the TandemHeart Transseptal Cannula Set-EF 72 was completed to verify flow vs. pressure drop (HQ), suture ring performance, mechanical integrity of the radiopaque marker disc encapsulation, and hemolysis. The Transseptal Cannula-EF 72 HQ testing results indicated a flow performance after six hour use that was consistent with the longer length, and substantially equivalent to the predicate THTC-EF cannula. The results of hemolysis testing, radiopaque marker disc testing and suture ring testing demonstrated that the THTC-EF 72 cannula was substantially equivalent in performance to the predicate devices.

#### Conclusions

The CardiacAssist TandemHeart Transseptal Cannula Set-EF 72 is substantially equivalent to the predicate CardiacAssist TandemHeart Transseptal Cannula Set-EF in design characteristics, performance, materials, method of construction, and intended use. The suture rings of the CardiacAssist TandemHeart Transseptal Cannula Set-EF 72 are also substantially equivalent to the predicate CardiacAssist Transseptal Cannula Set. The Radiopaque Marker disks at the tip of the CardiacAssist TandemHeart Transseptal Cannula Set-EF 72 are substantially equivalent to those in the BioMedicus Pediatric Femoral Venous Cannula.
