Abstract:
1. A medical device for delivering therapeutic material to a patient, the device comprising: an access sheath having a proximal section extending to a distal section and a working lumen formed in the proximal and distal sections, the distal section having a plurality of side ports formed therethrough in fluid communication with the working lumen, the distal section having a deflection section actuatable to bend at an angle for positioning the side ports in the patient; and a needle assembly configured to move within the working lumen between a retracted position and an extended position, the needle assembly including: a main cannula having a proximal portion extending to a distal portion comprising a distal wall, and a central lumen formed in the proximal and distal portions and terminating at the distal wall, the central lumen being configured to advance the therapeutic material; and a plurality of needles in fluid communication with the central lumen, the needles being attached to the distal portion of the main cannula proximal to the distal wall, the needles extending distally from the distal portion such that the needles are disposed within the access sheath in the retracted position and the needles extend through the side ports outwardly from the access sheath in the extended position to deliver the therapeutic material to the patient.
