Abstract:
1. A catheter system comprising: an elongate flexible catheter; a lumen that extends from a proximal insertion port to a side outlet opening; a penetrating guidewire that is separate and removable from the catheter, said guidewire being insertable into the proximal insertion port and thereafter advanceable through the lumen and out of the side outlet opening such that a distal portion of the guide wire is the only structure that extends out of the side outlet opening, said penetrating guidewire comprising a flexible guidewire body that is devoid of a lumen and which has a closed, sharp distal tip; and an orientation element useable to provide an indication of the trajectory on which the penetrating guidewire will advance from the catheter body; wherein the catheter has a longitudinal axis and wherein the lumen is configured such that the penetrating guidewire advances from the catheter at an angle that is less than 90 degrees relative to the longitudinal axis of the catheter.
