Indications for Use
The Rotarex™ Atherectomy System is intended for use as an atherectomy device and to break up and remove thrombus from native peripheral arteries or peripheral arteries fitted with stents, stent grafticial bypasses.
Device Story
Rotarex™ Atherectomy System is a percutaneous, over-the-wire device for removing atheromatic plaque and thrombi from peripheral arteries. System comprises a single-use catheter set and a drive system (control unit, motor, foot switch). Catheter features a rotating head with abrading facets and an internal rotating helix; driven by a motor in the handle at 40,000–60,000 RPM. Rotation creates aspiration to remove debris into a collecting bag. Used by physicians in clinical settings. Procedure involves navigating the catheter over a guidewire to the target lesion; mechanical rotation breaks up material; aspiration clears the vessel. Benefits include restoration of blood flow in occluded or stenosed peripheral vessels. This submission updates the Instructions for Use (IFU) to clarify procedural steps and anatomical considerations to reduce the risk of catheter/helix breakage.
Clinical Evidence
No clinical data or new performance testing was conducted for this submission, as there were no changes to the device design or technological characteristics.
Technological Characteristics
System consists of a catheter set and drive unit. Catheters are latex and phthalate-free, featuring a flexible outer covering, rotating head (two metal cylinders with side openings), and internal rotating helix.

Dear Aaron Conovaloff:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

#### Summarv of Change:
No changes have been made to the subject Rotarex™ Atherectomy System. The purpose of the submission is to obtain FDA clearance related to proposed revisions to the existing Rotarex™ Atherectomy System instructions for use (IFU). These IFU updates are being made to further clarify and emphasize important details regarding the procedural steps that are intended to reduce the risk of Rotarex™ catheter breakage events (including helix breaks) with use of the Rotarex™ catheter by supplementing and consolidating relevant information into one location within the warning section. These clarifications emphasize the importance of the procedural steps and anatomical considerations. An additional diagram illustrating instructions for device use is provided. BD will continue to monitor the Rotarex™ Atherectomy System via post-market data sources and is committed to investigating whether additional factors may exist that could contribute to helix fracture and/or breakage events to determine what, if any, additional actions may be needed.
{5}------------------------------------------------
## Device Description:
The Rotarex™ Atherectomy System is made up of a single use Rotarex™ Atherectomy Catheter Set and the Drive System, consisting of the control unit, motor and foot switch. For more detail on the Drive System, please see the manual provided with the Drive System. Read and understand all instructions prior to attempting any atherectomy procedure with the Rotarex™ Atherectomy System or any of its components.
The Rotarex™ Atherectomy Catheter Set is composed of multiple components, including the Rotarex™ Atherectomy Catheter, guidewire, collecting bag, and sterile drape. Rotarex™ Atherectomy Catheters are over-the-wire, single use, percutaneous devices for the removal of atheromatic plaque and thrombi in native arteries fitted with stents, stent grafts or native or artificial bypasses. The catheters are latex and phthalate free, and consist of a flexible outer covering, a rotating head, and a rotating helix which runs the length of the catheter. A lumen for the passage of the supplied quidewire runs the entire length of the helix and through the head of the catheter.
The catheter head is made up of two overlying metal cylinders, with two side openings. The outer cylinder is connected to the rotating helix, and the inner cylinder to the catheter shaft. The helix and the catheter head rotate at approximately 40.000-60.000 rpm depending on the model, by means of a gear box in the catheter housing and a motor contained within the catheter handle driven by the Drive System. The rotating outer cylinder is fitted with abrading facets at its foremost tip.

| 8F<br>110 cm | 5 mm | 2.7 mm | 40,000 | 75 | 0.018"<br>270 cm |
All components within the Rotarex™ Atherectomy Catheter Sets are supplied sterile for single use only. The method of sterilization is ethylene oxide.
#### Indications for Use of Device:
The Rotarex™ Atherectomy System is intended for use as an atherectomy device and to break up and remove thrombus from native peripheral arteries or peripheral arteries fitted with stents, stent grafts or native or artificial bypasses.
#### Technological Comparison to Predicate Device:
The technological characteristics of the subject device, the Rotarex™ Atherectomy System, are identical to those of the predicate device, in terms of the following:
- Identical Intended use
- ldentical Indications for use .
- . Identical target population
{6}------------------------------------------------
- Identical delivery system design ●
- Identical filter design and material
- Identical fundamental scientific technoloqy ●
- . ldentical packaging configuration
- . Identical Sterility Assurance and method of Sterilization
### Performance Data:
As no changes are being made to the Rotarex™ Atherectomy System associated with this 510(k) notice, no new performance testing was conducted on the subject device.
#### Conclusions:
The Rotarex™ Atherectomy System is substantially equivalent to the legally marketed predicate device. No changes have been made to the device or delivery system. The only changes being made are to revise the existing Rotarex™ Atherectomy System instructions for use (IFU). These IFU updates are being made to clarify the procedural steps that are intended to reduce the risk of Rotarex™ catheter breakage events (including helix breaks) with use of the Rotarex™ catheter. BD will continue to monitor the Rotarex™ Atherectomy System via post-market data sources and is committed to investigating whether additional factors may exist that could contribute to helix fracture and/or breakage events to determine what, if any, additional actions may be needed.
