Indications for Use

The CardioMEMS EndoSure s2 Wireless AAA Pressure Measurement System is intended for measuring intrasac pressure during endovascular abdominal aortic aneurysm (AAA) repair and may be used as an adjunctive tool in the detection of intraoperative endoleaks. It also may be used for measuring intrasac pressure during thoracic aortic aneurysm (TAA) repair.

Device Story

System monitors intrasac pressure during endovascular aneurysm repair (AAA/TAA). Components: permanent implantable sensor, sterile delivery system, electronics system. Sensor (fused silica, silicone-coated, nitinol loops) implanted in aneurysm sac during stent graft deployment. Electronics system antenna placed over patient abdomen interrogates sensor; acquires pressure signal. Output: pressure waveform and numerical data displayed on touch-screen; thermal printer generates hard copy. Used in OR by clinicians. Provides real-time pressure data to assist in detecting intraoperative endoleaks; aids clinical decision-making during stent graft placement; benefits patient by confirming successful aneurysm exclusion.

Clinical Evidence

Bench testing only. Device demonstrated biocompatibility and compatibility with MRI, ultrasound, pacemakers, and external defibrillators. Bench testing confirmed functional specifications.

Technological Characteristics

Implantable sensor: fused silica body, silicone coating, nitinol loops. Radiopaque marker bands for fluoroscopic visualization. Wireless interrogation via external antenna. Electronics system includes touch-screen display and integrated thermal printer. Permanent implant.

Indications for Use

Indicated for patients undergoing endovascular abdominal aortic aneurysm (AAA) or thoracic aortic aneurysm (TAA) repair to measure intrasac pressure and assist in intraoperative endoleak detection.

Regulatory Classification

Identification

Implantable intra-aneurysm pressure measurement system is a device used to measure the intra-sac pressure in a vascular aneurysm. The device consists of a pressure transducer that is implanted into the aneurysm and a monitor that reads the pressure from the transducer.

Special Controls

*Classification.* Class II (special controls). The special control is FDA's guidance document entitled “Class II Special Controls Guidance Document: Implantable Intra-Aneurysm Pressure Measurement System.” See § 870.1 (e) for the availability of this guidance document.

### D. Device Description

The CardioMEMS EndoSure s2 Wireless AAA Pressure Measurement System is designed to monitor pressure within the sac of a repaired aneurysm during endovascular stent graft placement. The CardioMEMS EndoSure s2 Wireless AAA Pressure Measurement System includes:

- The CardioMEMS EndoSure™ s2 Sensor with radio-opaque markings -(implant)
- । A sterile Delivery System (pre-loaded with the CardioMEMS EndoSure™ s2 Sensor)
- CardioMEMS EndoSure™ Electronics System

#### Li Intended Use:

The CardioMEMS EndoSure s2 Wireless AAA Pressure Measurement System is intended for measuring intrasac pressure during endovascular abdominal aortic aneurysm (AAA) repair and may be used as an adjunctive tool in the detection of intraoperative endoleaks. It also may be used for measuring intrasac pressure during thoracic aortic aneurysm (TAA) repair.

- F. Technological Characteristics Summary
The Sensor is implanted in the aneurysm sac during the time of stent graft deployment and is left in place in the excluded portion of the aneurysm as a permanent implant. The main body of the Sensor is manufactured from fused silica coated in silicone. Nitinol loops extend from and surround the Sensor body. Radiopaque marker bands at each end of the Sensor body allow visualization of the device under fluoroscopy.

The Sensor is interrogated using the antenna of the EndoSure Electronics System. The antenna is placed over the patient's abdomen in the area of the Sensor. Once the signal is acquired, a pressure waveform and numerical pressure data are displayed on the touch-screen. A printout of the data and waveform is generated from a thermal printer which is incorporated in the Electronics.

- ੁ. Performance Data
Testing has shown the EndoSure Sensor with Delivery System to be biocompatible and compatible with MRI, ultrasound, pacemakers and external defibrillators. Bench testing confirms that the device functions per its specifications.

Dear Ms. Powers:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
