Boston Scientific is initiating the removal of certain batches of Coyote" Over-the-Wire (OTW) Percutaneous Transluminal Angioplasty (PTA) Balloon Dilatation Catheter devices due to the potential for inflation/deflation difficulty during use in the peripheral vasculature. An internal investigation found that a manufacturing process variation resulted in catheters that may not properly inflate/deflate. This was limited to Coyote OTW batches manufactured from 12Sep2025 through 13Oct2025. The processing variation has since been addressed. No other material numbers or batches are impacted by this removal.

Boston Scientific issued an Urgent Medical Device Removal notice to its consignees on 12/3/2025 by letter delivered via a courier service. The notice explained the issue, clinical impact to the patient, and requested the following actions: "Instructions: 1.
