摘要：
The present invention is directed to a multi-angulated catheter and methods of using the multi-angulated catheter. The multi-angulated catheter is so dimensioned as to facilitate accessing the left ventricle from an arm of a patient. The multi-angulated catheter generally includes in order: (a) a coiled end； (b) a first straight portion having a first straight portion length； (c) a first shaft including a distal end connected to the first straight portion and a proximal end opposite the distal end, the first shaft and the first straight portion defining a first obtuse angle, the first shaft having a first shaft length； and (d) a second shaft connected to the first shaft on said proximal end. The catheter is flexible so as to afford being straightened when it is advanced over a guide wire. The catheter resiliently returns to a multi-angulated position after the guide wire is withdrawn.
