Intended Use

The TSP Crosser Transseptal Access System is intended to both puncture the interatrial septum during a transseptal catheterization procedure and to introduce various cardiovascular catheters into the left side of the heart.

Device Story

The TSP Crosser Transseptal Access System is a sterile, single-use device for transseptal catheterization. It consists of a steerable introducer sheath, a dilator, and a transseptal needle/stylet assembly. The physician operates the device under fluoroscopic guidance; a radiopaque nitinol loop at the distal end of the sheath aids in positioning the needle on the fossa ovalis. The sheath features a handle-mounted rotating knob for bidirectional deflection (up to 180°) to navigate cardiac anatomy. A hemostasis valve and sideport allow for fluid infusion, pressure monitoring, and blood aspiration. The system facilitates the puncture of the interatrial septum and provides a conduit for introducing cardiovascular catheters (up to 8F) into the left heart chambers. By enabling controlled access to the left atrium, the device assists in performing various cardiac interventions, potentially improving procedural efficiency and patient outcomes.

Clinical Evidence

Evidence includes in vitro bench testing (visual/dimensional verification, steerability, leakage, pushability, torqueability, simulated use, tensile strength, corrosion), biocompatibility testing (cytotoxicity, sensitization, reactivity, systemic toxicity, pyrogenicity, hemolysis, complement activation, thrombogenicity), in vivo animal studies, and clinical data collected outside the U.S. These studies demonstrate the device's safety, performance, and ability to successfully introduce catheters into the left heart chambers.

Technological Characteristics

System components: steerable introducer sheath (stainless steel braided shaft, PTFE liner, Pebax jacket), dilator (HDPE), and transseptal needle/stylet (304 stainless steel). Features bidirectional 180° tip deflection via pull-wire and handle-mounted rotating knob. Includes radiopaque nitinol loop for fluoroscopic visualization. Sterilized via ethylene oxide (EO). Compatible with 8F catheters and 0.035" guidewires. Hemostasis valve and sideport with three-way stopcock included.

Indications for Use

Indicated for patients undergoing transseptal catheterization procedures requiring puncture of the interatrial septum and introduction of cardiovascular catheters into the left heart chambers.

#### Device Description 6.4

The TSP Crosser System is intended to be used both to puncture the interatrial septum during a transseptal catheterization procedure and to introduce various cardiovascular catheters into the left heart chambers. The main components of the TSP Crosser System are:

{4}------------------------------------------------

- . Steerable introducer sheath with handle and radiopaque wire loop that is compatible with catheters up to 8F
- . Dilator that is compatible with guidewires up to a maximum diameter of 0.035"
- Transseptal needle with Stylet ●

The System is provided sterile (EO) and is intended for single use only. The device is designed to provide controlled transseptal access in the cardiac left atrial anatomy. The TSP catheter introducer sheath is an elongated shaft with a central lumen capable of incorporating the needle and stylet assembly, the dilator, as well as allow passage and orientation of operational catheters up to 8F. The introducer incorporates a steerable tip that can be deflected bidirectionally up to 180° with a curvature radius of 22mm. The steerable introducer handle includes a rotating knob that maintains the rotational and longitudinal positioning of the sheath and deflects the sheath's tip 180° on each side. There is a nitinol loop wire positioned at the distal end of the introducer that is visible under fluoroscopy and provides a visual aid to the user when positioning the needle on the fossa ovalis. The introducer contains a hemostasis valve to minimize blood loss during catheter introduction and/or exchange. A sideport with a three-way stopcock is provided for air or blood aspiration, fluid infusion, blood sampling, and pressure monitoring.

The dilator has an outer diameter of 8F and inner diameter of 0.035" and includes a central lumen that facilitates the transseptal needle/stylet in a similar fashion to conventional dilators. The transseptal needle assembly consists of a luminal stainless-steel needle and solid stainlesssteel stylet. The needle is used to puncture the interatrial septum during the catheterization procedure and houses a central lumen that accommodates the stylet.

#### 6.7 Performance Data and Substantial Equivalence

The technical characteristics between the subject device and the predicate devices have been evaluated through design, material and dimensional comparison, bench and biocompatibility tests to provide evidence of substantial equivalence. The TSP Crosser Transseptal Access System is substantially equivalent to the predicate devices based on comparison of the devices functionality, compatibility, technological characteristics and indications for use.

In vitro bench testing was performed on the TSP Crosser System to assure reliable design and performance. The non-clinical tests performed include Visual and Dimensional Verification, Steerability, Air Leakage, Liquid Leakage, Pushability, Torqueability, Simulated Use, Tensile Strength, and Corrosion.

Biocompatibility testing consisted of Cytotoxicity, Sensitization, Intracutaneous Reactivity, Systemic Toxicity, Pyrogenicity, ASTM Hemolysis (Direct and Indirect), SC5b-9 Complement Activation and In Vivo Thrombogenicity.

In vivo animal studies were performed to confirm the safety and performance of the TSP Crosser System in a left heart catheterization and to demonstrate the ability of the System to successfully introduce commercial percutaneous catheters into the left chambers of the heart.

Clinical data was also collected outside the United States that supports the safety and performance of the TSP Crosser System for its labeled indications for use.

{7}------------------------------------------------

#### 6.8 Conclusions

Transseptal Solutions believes the proposed TSP Crosser System is substantially equivalent to the legally marketed predicate devices. The indications for use, methods of operation, design and materials used are either identical or substantially equivalent to existing legally marketed predicate products. In addition, performance testing, in addition to in vivo animal studies and clinical data supports substantial equivalence of the proposed and predicate devices.
