Abstract
The invention is directed to a catheter suitable for medical procedures such as cardiac ablation. The catheter includes a front-loaded catheter tip with an electrically active element. The catheter can include an elongate catheter shaft assembly having an inner shaft member with a distal end and a proximal end, and an outer shaft member with a distal end, a proximal end, and a lumen between the distal end and the proximal end. The inner shaft member can be inserted into the lumen of the outer shaft member along a longitudinal direction. The inner shaft member can include, at the distal end, a catheter tip member having a lateral dimension that is larger than a lateral dimension of the lumen of the outer shaft member. The catheter tip member includes at least one electrically active element, and the proximal end of the inner shaft member has at least one electrode disposed on the external surface of the shaft member, such that when inserted into a handle, the electrode electrically contacts an electrical connector element.
