Tortuous path injection device and method

A catheter, comprising:

• an elongate shaft having a distal end, a proximal end, and a lumen therethrough;
• the elongate shaft including a first curved portion proximate the distal end of the elongate shaft;
• the first curved portion of the elongate shaft defining a first plane;
• the elongate shaft including a second curved portion disposed between the distal end of the elongate shaft and the first curved portion of the elongate shaft;
• the second curved portion of the elongate shaft defining a second plane;
• and
• wherein the second plane is substantially orthogonal to the first plane.

A catheter, comprising:

• a first elongate shaft having an inner surface defining a lumen;
• a second elongate shaft slidingly disposed within the lumen of the first elongate shaft;
• the first elongate shaft including a curved portion defining a first plane;
• wherein the second plane is substantially orthogonal to the first plane;
• the second elongate shaft including a distal portion extending beyond a distal end of the first elongate shaft;
• the distal portion of the second elongate shaft including a curved portion defining a second plane;
• wherein the first plane intersects the second plane at an angle.
