Systems and methods for deploying a sensor assembly onto a cardiac lead are disclosed. The sensor assembly can include a resilient cuff having one or more sensor modules for sensing physiological parameters within the body. The resilient cuff may have a substantially cylindrical shape having an inner diameter that is smaller than an outer diameter of the lead body onto which the cuff is deployed such that the cuff is retained on the lead body by frictional forces. The sensor assembly may be deployed in conjunction with a new lead to be implanted within a chamber of the patient's heart or a body vessel, or may be deployed onto an existing, implanted lead implanted within the patient's body.
