Clinical Use and Safety of the Xtreme Touch (Magic Touch PTA)- Neo Sirolimus Coated PTA Balloon Catheter in the Treatment of Infrainguinal Peripheral Arterial Disease

It is imperative to have effective treatment strategies for PAD which can maintain the patency of arteries. The current standard of care for PAD is angioplasty which includes usage of drug coated balloons (DCB). Paclitaxel is the only anti-proliferative drug available in all currently available DCB technology. Sirolimus is another highly effective anti-proliferative drug of immense potential as demonstrated by superior results in Sirolimus drug eluting stents in coronary disease. The physical properties of Sirolimus have made it challenging for it to be similarly applied to DCB technology and it is only due to recent advances in nanotechnology that it is now possible to develop Sirolimus coated balloons (SCB), which is the study device used in this study. The study device allows delivery and deposition of sirolimus to the arterial wall. By applying this agent into lesions in peripheral arterial disease, this study aim to effectively reduce neointimal hyperplasia, and therefore prolong the patency of the artery and improve our limb salvage rates for PAD and CLI patients. Subjects will be followed up in the clinic at 6 month, 12 month, and 24 month post-intervention to assess primary and secondary outcome of safety and efficacy.

Inclusion criteria

• Age ≥ 21 years or minimum age
• Subject must be willing to sign a Patient Data Release Form or Patient Informed Consent where applicable
• Lesion(s) in the infrainguinal arteries between 3 to 6mm which are suitable for endovascular treatment treated with the Xtreme Touch - Neo sirolimus PTA balloon catheter. For below the knee (BTK) arteries, lesions located in the proximal 200mm of the artery.

Exclusion criteria

• Life expectancy ≤ 1 year
• Subject is currently participating in another investigational drug or device study that has not reached ist primary endpoint yet
• Subject is pregnant or planning to become pregnant during the course of the study
• Failure to achieve less than 30% residual stenosis in pre-existing lesion after plain balloon angioplasty
• Failure to successfully cross the target lesion with a guide wire (successful crossing means tip of the guide wire distal to the target lesion in the absence of flow limiting dissections or perforations
