Intended Use

The Transseptal Cannula Set 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 a suitable extracorporeal blood pump unit which returns blood to the patient via the femoral artery or other appropriate site.

Device Story

Transseptal Cannula Set facilitates temporary left ventricular bypass; provides access to left atrium via femoral vein. Components include 21 Fr. polyurethane cannula with side holes for inflow, 13 Fr. obturator for advancement/de-airing/contrast delivery, and 14/21 Fr. polyethylene two-stage dilator. Used in clinical setting; operated by physicians. Cannula secured to patient via suture wing/rings. Device connects to external blood pump; blood returned to patient via femoral artery. Benefits include improved flow/pressure drop performance and kink resistance compared to predicate. Enables short-term circulatory support.

Clinical Evidence

Bench testing only. Evaluated flow vs. pressure drop (HQ), kink radius, tensile strength, leak testing, and biocompatibility. Results showed superior HQ and kink radius performance compared to predicate. Tensile and leak testing exceeded design requirements. Biocompatibility met ISO 10993-1 and FDA Blue Book Memorandum #G95-1 standards.

Technological Characteristics

Set includes 21 Fr. polyurethane cannula, 13 Fr. polyurethane obturator, and 14/21 Fr. polyethylene two-stage dilator. Features include suture wing/rings, radiopaque marker band, and depth markings (40-62 cm). Designed for 0.035 in. guidewire compatibility. Biocompatibility per ISO 10993-1.

Indications for Use

Indicated for patients requiring temporary (≤6 hours) left ventricular bypass via transseptal catheterization of the left atrium through the femoral vein.

Regulatory Classification

Identification

A catheter cannula is a hollow tube which is inserted into a vessel or cavity; this device provides a rigid or semirigid structure which can be connected to a tube or connector.

#### Device

Trade/Proprietary Name: CardiacAssist-Transseptal Cannula Set Common Name: Transseptal Cannula Classification Name: Catheter Cannula

### Predicate Device

Elecath Percutaneous Left Atrial Cannulation Set (K854511)

#### Device Description

The Transseptal Cannula Set consists of three components: (1) 21 Fr. Transseptal Cannula, (2) 13 Fr. Obturator, and (3) 14/21 Fr. Two-stage Dilator, that accept a 0.035 in. guidewire.

The 21 Fr. Transseptal Cannula (Figure 1) allows for drainage of the left atrium during ventricular bypass. It has 14 side holes in addition to the tip opening for inflow at the distal end, a barbed fitting at the proximal end, and insertion depth markings from 40 to 62 cm measured from the distal end. The Transseptal Cannula also includes a Suture Wing and 2 Suture Rings to provide a means for securing it to the patient.

Image /page/1/Figure/0 description: The image shows a medical device, specifically a CardiacAssist, Inc. product. The device appears to be a catheter or similar instrument, featuring a central hub with multiple ports or connections. The catheter tube is marked with numerical gradations, possibly indicating depth or measurement markers.

Figure 1. 21 Fr. Transseptal Cannula

The 13 Fr. Obturator (Figure 2) is used to advance the Cannula to the right atrium from the inguinal area and then across the atrial septum into the left atrium. It contains a luer hub and aspiration side holes at both the distal and proximal ends to facilitate de-airing and to allow for use of contrast material to facilitate final positioning of the Cannula. It also contains a radiopaque marker band proximal to the Cannula drainage holes when the Obturator is inserted in the Cannula.

Image /page/1/Figure/3 description: The image shows a long, thin object that appears to be a tool or instrument. It has a cylindrical shape with a wider, more complex structure at one end, possibly a handle or connector. The object is divided into sections, with a break in the middle suggesting it might be extendable or modular. The overall impression is of a precision instrument, possibly used in engineering or a related field.

The 14/21 Fr. Dilator (Figure 3) is provided for pre-dilation of the fossa ovalis once left atrial access is achieved via standard transseptal technique.

#### Intended Use

The Transseptal Cannula Set 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 a suitable extracorporeal blood pump unit which returns blood to the patient via the femoral artery or other appropriate site.

#### Comparison of Technological Characteristics

The Transseptal Cannula Set contains a polyurethane Transseptal Cannula with a Suture Wing and two Suture Rings, a polyurethane Obturator, and a polyethylene Two-stage

Dilator. An introducer needle, transseptal puncture kit and guidewire are to be provided by the user. The Elecath device contains a vinyl transseptal cannula and a stainless steel obturator with an extension plus an introducing catheter and needle, guidewire, and transseptal needle.

### Performance Data

Testing of the Transseptal Cannula Set was completed for flow vs. pressure drop (HQ) and kink radius performance, tensile strength, leak testing and biocompatibility. The Transseptal Cannula HQ and kink radius performance after six hour use was substantially better than that of the Elecath cannula. The results of the tensile strength and leak testing indicated that the device exceeded the design requirements. The biocompatibility test results indicated that the transseptal Cannula Set successfully met the requirements of FDA's Blue Book Memorandum #G95-1 guidance and ISO 10993-1.

### Conclusions

The Transseptal Cannula Set is substantially equivalent to the Elecath Percutaneous Left Atrial Cannulation Set
