Jetstream™

Atherectomy System

Importance of Calcium Removal

  • Arterial Dissections are commonly associated with plaques containing significant calcium deposits1
  • Diabetic Patients have a tendency for higher calcification2
  • Drug-Coated Balloon Efficacy could be impacted by calcium3

Jetstream Calcium Study4​

Objective

To better understand the mechanism of lumen gain when using the Jetstream Atherectomy System to treat calcified peripheral artery lesions, i.e., patients with claudication and lesions with superficial calcium >90° and >5 mm in length as determined by intravascular ultrasound (IVUS).

Study Design

Jetstream Calcium Study - Design
 

Why is an IVUS Study Unique?

  • Sensitivity to detect calcium by IVUS reported at 90%5
  • Statistical ability to measure luminal gain 

Primary Endpoint

Calcium removal and luminal gain, measured by comparing pre-intervention to post-atherectomy IVUS images

Treatment Device

The 2.1/3.0mm Jetstream catheter was used in all cases

Case Example from Jetstream Calcium Study
Distal SFA/Proximal Popliteal*

Successful debulking with the Jetstream Atherectomy System in a distal right SFA/proximal popliteal artery lesion. The pre-atherectomy IVUS image reveals a lumen area of 2.5 mm². The post-atherectomy images reveal a lumen area of 7.6 mm² and impressive debulking with Jetstream Atherectomy even before adjunctive therapy.

*Results from case studies are not necessarily predictive of results in other cases. Results in other cases may vary.
