Intended Use

The Keystone Heart Transseptal System is intended to provide a dilator and sheath through which other medical devices can be delivered to targeted locations within the cardiac anatomy. The Keystone Heart Transseptal System is intended to be introduced into the body through the venous system. The distal end of the sheath may be advanced across the interatrial septum of the heart into the left atrium. The Keystone Heart Transseptal System is intended to be delivered to the targeted location using echocardiographic and/or radiographic/fluoroscopic image guidance.

Device Story

Sterile, single-use, tridirectional introducer system comprising sheath and dilator; used in cardiac catheterization procedures. Physician operates handle assembly featuring rotating knob and steering lever to deflect distal sheath tip; dilator advanced/retracted through inner lumen; hemostasis maintained via static valve. System introduced via venous system; guided to target anatomy using echocardiographic or fluoroscopic imaging. Acts as guide/platform for delivery of other diagnostic/therapeutic devices to left atrium via interatrial septum. Benefits patient by facilitating minimally invasive access to cardiac structures.

Clinical Evidence

Bench testing only. No clinical or animal data. Bench tests included visual/dimensional analysis, deflection, insertion/removal, dilator lock/buckle, leak/flush, torque, and imaging visualization. Biocompatibility testing included cytotoxicity, sensitization, reactivity, systemic toxicity, pyrogenicity, ASTM hemolysis, complement activation, and thrombogenicity.

### Device Description:

The Keystone Heart LIM Precision Steerable TS Transseptal System is a sterile, single use, tridirectional introducer. The system consists of a sheath and a dilator.

The sheath has a handle assembly with a rotating knob and steering lever that deflects the distal end of the sheath. The dilator can be inserted and advanced or retracted through the inner lumen of the sheath. Hemostasis is maintained along the dilator lumen via a hemostatic valve. The dilator lumen is flushable. Once the dilator is generally in the proper position relative to the sheath, an actuator is tightened to secure the dilator to the handle. A knob is then turned to slowly advance the dilator.

### Intended Use:

The Keystone Heart Transseptal System is intended to provide a dilator and sheath through which other medical devices can be delivered to targeted locations within the cardiac anatomy. The Keystone Heart Transseptal System is intended to be introduced into the body through the venous system. The distal end of the sheath may be advanced across the interatrial septum of the heart into the left atrium. The Keystone Heart Transseptal System is intended to be delivered to the targeted location using echocardiographic and/or radiographic/fluoroscopic image guidance.

### Indications for Use:

The LIM Precision Steerable TS Transseptal System is indicated for introducing various cardiovascular catheters into the heart, including the left side of the heart through the interatrial septum

## Summary of Technical Characteristics as Compared to the Predicate Device:

The proposed device is substantially equivalent to the design and materials in the predicate device. The Keystone Heart Transseptal System has the same intended use and fundamental scientific technology as the predicate device. All technological characteristics of the Keystone Heart Transseptal System are substantially equivalent to the predicate device, including packaging, biocompatibility, sterilization, and labeling. Where dimensional differences exist between the subject device and the predicate device, performance testing demonstrates that these differences do not adversely affect safety and effectiveness. The introducer acts as a functioning guide/platform for introduction of other diagnostic and therapeutic devices.

The Keystone Heart Transseptal System is substantially equivalent to currently marketed devices intended for introducing various cardiovascular catheters into the heart, including the left side of the heart through the interatrial septum, specifically the BioCardia 8.5F Avance® Steerable Introducer, K190941. Keystone Heart is utilizing a reference device, the St. Jude Medical Agilis NxT™ Steerable Introducer, K110450. This reference device has the same basic design and indications as both the predicate and subject device, but also has a guidewire supplied with the device. The predicate and subject devices are not supplied with a guidewire.

# Summary of Technical Characteristics as Compared to Predicate

{6}------------------------------------------------

### Performance Data:

The technical characteristics between the subject device and the predicate device have been evaluated through design, material and dimensional comparison, bench, and biocompatibility tests to provide evidence of substantial equivalence. The Keystone Heart Transseptal 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 Keystone Heart Transseptal System to assure reliable design and performance. The non-clinical tests performed include Visual Inspection and Dimensional Analysis, Primary and Secondary Deflection, Insertion and Removal, Dilator Lock and Buckle, Leak and Flush, Femoral and Septal Insertion, Torque Test, and Fluoroscopy and Ultrasound Visualization.

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

No animal or human testing was conducted on the Keystone Heart Transseptal System.

#### Conclusion:

Keystone Heart believes the proposed Keystone Heart Transseptal System is substantially equivalent to the legally marketed predicate device. The indications for use, methods of operation, design and materials used are either identical or substantially equivalent to the existing legally marketed predicate product.
