Patent ID: 8784360

Claim:
An infusion catheter system comprising: a first delivery catheter comprising a proximal end and a distal end, wherein the first delivery catheter comprises a first delivery lumen extending from the proximal end of the first delivery catheter to a first infusion location located distally from the proximal end of the first delivery catheter, wherein the first infusion location comprises an opening through which fluid moving distally through the first delivery lumen exits the first delivery catheter; a second delivery catheter comprising a proximal end and a distal end, wherein the second delivery catheter comprises a second delivery lumen extending from the proximal end of the second delivery catheter to a second infusion location located distally from the proximal end of the second delivery catheter, wherein the second infusion location comprises an opening through which fluid moving distally through the second delivery lumen exits the second delivery catheter; a connector comprising a supply port, a first exit port in fluid communication with the first delivery lumen in the first delivery catheter, and a second exit port in fluid communication with the second delivery lumen in the second delivery catheter, wherein fluid entering the connector through the supply port exits the connector through either the first exit port or the second exit port; a first flow restrictor located between the first exit port of the connector and the first delivery lumen such that fluid flowing through the first exit port into the first delivery lumen must pass through the first flow restrictor, wherein the first flow restrictor comprises a disk-shaped body that comprises a first side facing the first exit port and a second side facing the first delivery lumen, the disk-shaped body further comprising an orifice formed through the disk-shaped body from the first side to the second side, wherein the orifice comprises a hole surrounded by the disk-shaped body, wherein fluid flowing through the first flow restrictor must pass through the orifice; a second flow restrictor located between the second exit port of the connector and the second delivery lumen such that fluid flowing through the second exit port into the second delivery lumen must pass through the second flow restrictor; and an anchor comprising an anchor body operable to secure to tissue at a selected location, wherein the anchor body comprises engagement surfaces configured to receive and immobilize the first delivery catheter as it passes through the anchor, wherein the first flow restrictor is housed in the anchor body.
