FDA has classified as Class 1 an Oscor recall of its TB Temporary Bipolar Pacing Leads due to connector separation that may cause a loss of pacing. The TB Leads are used by physicians to stimulate or pace the heart to increase heart rate. Temporary pacing leads are placed into a vein and advanced, so the tip touches the inside of the heart to allow heart beat sensing and pacing as needed. The connector of the lead must be attached to an external pacing pulse generator for stimulation energy and timing, an FDA recall [notice](https://www.fda.gov/MedicalDevices/Safety/ListofRecalls/ucm626501.htm?utm%5Fsource=CDRHTwitterD) says.
