Intended Use

The SafeSept is indicated for use in procedures where access to the transseptal technique is desired. The SafeSept Transseptal Guidewire is intended for single use only.

Device Story

SafeSept Transseptal Guidewire is a 0.014-inch diameter, 135cm long nitinol wire used in healthcare facilities for transseptal heart procedures. Inserted via femoral vein, it is advanced to the fossa ovalis supported by a needle and dilator. The sharp distal tip perforates the fossa ovalis; once unsupported, the wire becomes atraumatic. A radiopaque coil allows fluoroscopic visualization in the left atrium, while proximal marker bands indicate tip position relative to the needle. The device guides the needle, dilator, and introducer from the right to the left atrium. It benefits patients by facilitating safe transseptal access for cardiac interventions. Used by physicians in hospital settings.

Clinical Evidence

Bench testing only. Testing included visual/dimensional inspection, particulate testing (USP <788>), surface finish, corrosion resistance, tensile strength, fracture/flex testing, curve integrity, torque testing, and radiopacity. Biocompatibility testing performed per ISO 10993 standards, including cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, genotoxicity, and hemocompatibility (including in-vivo dog thromboresistance).

Technological Characteristics

Nitinol super-elastic wire; 0.014" diameter; 135cm length. Features radiopaque coil and printed marker bands. Sterilized via 100% ethylene oxide (ANSI/AAMI/ISO 11135-1) to SAL 10^-6. Single-use. Mechanical device; no software or electronics.

Indications for Use

Indicated for patients requiring access to the left atrium via transseptal technique. For single use only.

# 510(k) Summary

#### Submitter

Pressure Products Medical Device Manufacturing LLC. 1 School Street Morton, PA 19070 Phone: [phone] Fax: [phone]

Contact Person: Andrew Armour Prepared: October 19, 2017

#### Identification of the Device

Proprietary-Trade Name: SafeSept® Transseptal Guidewire Device Class: Class II Classification Name: Trocar (CFR 870.1390) Common/Usual Name: Transseptal Guidewire Product Code: DRC

#### Equivalent Legally Marketed Devices

Oscor, SafeSept® Transseptal Trocar Guidewire, K081986

#### Description of the Devices

The SafeSept® Transseptal Guidewire is 0.014″ in diameter and 135cm long and consists of a flexible memory wire material called nitinol. The components of the SafeSept include the 0.014″ transseptal guidewire, dispenser and straightener, and sterile packaging and labeling. There is one model number for the SafeSept, SS-135. The SafeSept is sterilized by 100% ethylene oxide cycle and is for single-use only. The SafeSept is used in a healthcare facility/hospital.

The SafeSept is used in transseptal procedures to gain access to the left atrium through the right side of the heart. The device is used by inserting the device through the femoral vein. The SafeSept is then advanced to the fossa ovalis with the support of the needle and dilator. The SafeSept's sharp distal tip is able to perforate through the fossa ovalis, a thin wall between the right and left atrium, when it is supported by a transseptal needle and dilator. When the wire is no longer supported, it is atraumatic and operates as a typical 0.014″ diameter guidewire. A radiopaque coil located along the shaft allows for fluoroscopic visualization of the wire within the left atrium and proximal marker bands help determine the location of the guidewire tip in relation to the tip of the needle. The guidewire's duration in the body is less than 24 hours.

#### Indications for Use

The SafeSept® is indicated for use in procedures where access to the left atrium via the transseptal technique is desired. The SafeSept Transseptal Guidewire is intended for single use only.

The Indications for Use statement for the SafeSept transseptal guidewire device is identical to the predicate device. Both devices have the same intended use and are used in conjunction with a transseptal needle to create the primary puncture in the interatrial septum. The devices guide the needle, dilator, and introducer through the septum from the right side of the heart to the left side.

# Comparison of Technological Characteristics with the Predicate Device

The technological characteristics of this device are the predicate device. The main difference between the subject device and the predicate device is the length of the guidewire. The predicate SafeSept device is 120cm in length and the currently marketed SafeSept is 135cm. The subject and predicate device are based on the follow technological elements:

- The guidewire is manufactured from nitinol wire that is super-elastic so that it can have a 'J' curve with a sharp tip
- Radiopaque coil used by the physician to locate SafeSept and to guide supporting devices like the transseptal needle, dilator, and sheath across the fossa
- . Device inserted through the transseptal needle so that it can be used in the transseptal procedure
- . Creates the primary puncture of the fossa with the sharp tip
- . Coil is used to dilate the fossa further so that the needle can then be inserted through the fossa rather then used as the primary puncture
- . Printed markers are along the body for the physician to use as a guide to understand how far the SafeSept is in relation to the supporting devices

## Performance Testing

The following performance tests were performed in support of substantial equivalence to the predicate:

- Visual and dimensional inspection
- Particulate testing (USP <788>, Light Obscuration Method) ●
- Surface finish assessment
- Corrosion resistance
- Guidewire tensile strength
- Fracture and Flex testing
- Curve Integrity testing
- Torque Testing
- Packaging testing
- Radiopacity assessment

In addition, the sterilization conditions have been validated in accordance with ANSI/AAMI/ISO 11135-1, Sterilization of health care products - Ethylene oxide - Part 1: Requirements for development, validation and routine control of sterilization process for medical device is sterilized to a SAL of 10-6. The results of the testing demonstrated the subject device performed equivalently to the predicate device.

## Biocompatibility Testing

The biocompatibility evaluation for the SafeSept was conducted in accordance with FDA 510(k) Memorandum- #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing' " June 16, 2016, and International Standard ISO 10993-"Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by the FDA. The following tests were performed:

- ISO 10993-5 Cytotoxicity
- ISO 10993-10 Sensitization
- ISO 10993-10 Irritation/Intracutaneous Reactivity .

{5}------------------------------------------------

- ISO 10993-11 Acute Systemic Toxicity ●
- . ISO 10993-11 Pyrogenicity
- ISO 10993-3 Genotoxicity ●
- . ISO 10993-4 Hemocompatibility - ASTM Hemolysis Complete
- ISO 10993-4 Hemocompatibility - In-vivo Dog Thromboresistance
- ISO 10993-4 Hemocompatibility Complement Activation Complete with C3a & SC5b-9 ●

The SafeSept transseptal guidewire is considered an external communicating device with circulating blood contact and limited exposure (less than 24 hours). The SafeSept met the requirements set forth in ISO-10993.

## Conclusion

When compared to the predicate device, the SafeSept transseptal guidewire is substantially equivalent in design, technological characteristics, materials and performance testing.
