Indications for Use

The ClearLumen II Peripheral Thrombectomy System is intended to: - remove/aspirate fluid and break-up soft emboli and thrombus from the peripheral vasculature, and - subselectively infuse/deliver diagnostics or therapeutics with or without vessel occlusion.

Device Story

Multi-lumen catheter system for peripheral thrombectomy; performs simultaneous hydro-mechanical thrombus disruption and aspiration. System includes aspiration catheter, pump set, and peripheral saline drive unit (SDU). SDU delivers high-pressure saline stream to catheter distal tip to macerate thrombus; suction provided by external 60 ml VacLok syringe draws macerated material into primary lumen for collection. Used in clinical settings; operated by physicians. SDU contains microprocessor-controlled circuit/firmware monitoring motor and vacuum status; LED indicators provide status updates. Device enables thrombus removal and targeted infusion of diagnostics/therapeutics. Benefits include efficient thrombus clearance and localized delivery of agents.

Clinical Evidence

No clinical data generated. Substantial equivalence supported by bench testing (design verification) including saline/contrast flow rates and infusion/lumen pressure testing. Biocompatibility, sterilization, and transportation testing relied on identity to reference device.

Technological Characteristics

Multi-lumen catheter; 115 cm length; 0.105" max OD; over-the-wire configuration. SDU is IV-pole mounted, 24V powered, microprocessor-controlled. Employs hydro-mechanical disruption via saline stream and vacuum-based aspiration. Connectivity: external power supply, manual syringe interface. Software: firmware-controlled motor/vacuum monitoring.

Indications for Use

Indicated for removal/aspiration of fluid and soft emboli/thrombus from peripheral vasculature and subselective infusion/delivery of diagnostics or therapeutics with or without vessel occlusion.

#### Device Description:

The ClearLumen II Peripheral Thrombectomy System is a multi-lumen device that allows for simultaneous hydro-mechanical thrombus disruption and thrombus aspiration. It is designed to simultaneously deliver a stream of high pressure saline via a displacement pump to the distal tip of the catheter, while aspirating thrombotic material macerated by the saline stream.

The ClearLumen II Peripheral Thrombectomy System consists of one aspiration catheter, which connects to the ClearLumen II Pump Set and the ClearLumen Peripheral Saline Drive Unit (SDU). In use, thrombus enters the distal catheter tip via the suction force provided by a 60 ml VacLok syringe, which is connected to the vacuum sensor. The peripheral SDU and pump set deliver a stream of sterile saline through the secondary lumen to break up and dilute the thrombus within the catheter. The diluted thrombus and saline is drawn back through the primary lumen and deposited into the syringe. No saline is injected into the patient during normal operation.

The ClearLumen II Peripheral catheter has the ability to infuse fluid through the aspiration lumen and saline lumen.

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

For infusion through the aspiration lumen, an appropriate sized syringe filled with fluid is infused to the treatment area by passing through the side arm of the rotating hemostasis valve (RHV) that is attached to the catheter.

For infusion through the saline lumen, a non-vented Luer cap is placed between the rotating hemostasis valve (RHV) side arm and the pressure monitor tubing.

The proximal end of the pump set consists of a spike and an in-line drip chamber that is used to pierce the saline bag and connect the pump set to the saline source. The cassette, which is centered in the pump set, contains a piston pump and is mounted onto the peripheral SDU. The cassette is powered by the motor contained in the peripheral SDU. The distal end of the pump set has a connector, which mounts to the proximal end of the Y-connector of the peripheral catheter and delivers the saline to the peripheral catheter.

The peripheral SDU is a reusable, IV pole mounted device. The fork drive of the peripheral SDU is designed to run the piston pump contained in the pump set to deliver the stream of saline to the peripheral catheter, when activated by the vacuum sensor. Vacuum is achieved by a vacuum syringe (not provided), which is connected to the vacuum sensor. The vacuum sensor is connected to the aspiration lumen on the Y-connector of the peripheral catheter. The peripheral SDU contains a microprocessor controlled circuit and firmware that monitors various functions of the motor and vacuum to assure that the device is functioning as expected. Various colored LED lights on the front panel indicate to the user the current status of the SDU. Energy is provided by a 24 volt external power supply, which is connected to mains power.

## Indications for Use:

The ClearLumen II Peripheral Thrombectomy System is intended to:

- remove/aspirate fluid and break-up soft emboli and thrombus from the peripheral vasculature, and
- subselectively infuse/deliver diagnostics or therapeutics with or without vessel occlusion.

The ClearLumen II Peripheral Thrombectomy System is substantially equivalent to the predicate device with regard to its indication for use. The ClearLumen II Peripheral Thrombectomy System is being used as a reference device, and is identical in design to the subject device.

#### Summary of Non-Clinical Performance Data:

Device evaluation consisted of in vitro testing performed pursuant to Walk Vascular's risk analysis. All data met the acceptance criteria and fell within pre-determined product specifications and external standard requirements. The following testing was performed to support the new indication for use:

Design Verification Testing:

- Saline flow rate through aspiration lumen
- 60% ionic contrast media flow rate through aspiration lumen
- Infusion pressure of aspiration lumen
- Saline lumen pressure

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

### Biocompatibility Testing:

Biocompatibility testing was not conducted, as the subject device is identical to the reference device.

#### Sterilization Testing:

Sterilization testing was not conducted, as the subject device is identical to the reference device.

### Transportation and Shelf Life Testing:

Transportation testing was not conducted, as the subject device is identical to the reference device. Additional shelf life testing was conducted to support the new indication.

The data from the in vitro testing above supports the substantial equivalence of the subject device to the predicate and reference device.

## Summary of Pre-Clinical and Clinical Data:

No pre-clinical or clinical data were generated to establish substantial equivalence. Bench data and data are considered adequate to support a determination of substantial equivalence.

#### Summary:

Based on the intended use, and in vitro performance information provided in this premarket notification, the ClearLumen II Peripheral Thrombectomy System is substantially equivalent to the predicate device.
