Abstract: A method of manufacturing a catheter tip by electroplating a conductive material over an insert comprising a negative to a domelike shape thereby forming a shape of the catheter tip comprising a dome with the domelike shape, selectively positioning a plurality of irrigation holes between outer and inner surfaces of the catheter tip, removing the insert thereby leaving the catheter tip and the plurality of irrigation holes, and electropolishing the catheter tip. In other examples, the insert is not removed and instead the step of electroplating causes the insert to be encapsulated with the conductive material thereby forming the catheter tip.
