Intraluminal needle injection substance delivery system with filtering capability
First Claim
1. A delivery system for administering therapeutic drugs or substances in a body vessel of a patient, comprising:
- a delivery catheter having a proximal end and a distal end and a delivery lumen for receiving the cannula of a syringe, the delivery lumen having a distal end through which the cannula extends for the administration of a therapeutic drug or substance to the body vessel; and
means associated with the delivery catheter for capturing unwanted particles which may be entrained in the body fluid passing through the body vessel.

Abstract
An intraluminal needle injection substance delivery system includes a delivery catheter having a delivery lumen extending therethrough to provide a conduit by which a drug delivery device can extend through to inject a therapeutic drug or substance to an area of treatment in a body vessel. The delivery system includes filtering capability for capturing possible unwanted debris which may be entrained in the patient'"'"'s vasculature. The filtering device used in accordance with the delivery catheter may include a filtering element placed downstream from the area in which the therapeutic drug or substance is to be administered. The delivery lumen can be attached to the filtering device for deployment within the patient'"'"'s vasculature. In this fashion, as the filtering device is expanded from a collapsed, delivery position to an expanded position within the patient'"'"'s vasculature, the end of the delivery lumen will be positioned near or in contact with the target area in the patient'"'"'s vasculature. A substance delivery device, such as a syringe having an elongated cannula, can be placed in the delivery lumen to inject the vessel wall with a drug or other therapeutic substance.

37. A method for administering therapeutic drugs or substances intraluminally in a body vessel of a patient, comprising:
-
providing a delivery system including a delivery catheter having a proximal end and a distal end and a delivery lumen for receiving the cannula of a drug delivery device, the delivery lumen having a distal end through which a cannula extends for the administration of a therapeutic drug or substance to the body vessel and an filtering device associated with the delivery catheter for capturing unwanted particles which may be entrained in the body fluid passing through the body vessel;
advancing the delivery catheter intraluminally through the patient to position the end of the delivery lumen near or in contact with the location of the body vessel where the drug or substance is to be administered;
deploying the filtering device within the body vessel;
advancing the cannula of a drug delivery device through the delivery lumen placing the end of the cannula near or into the body vessel; and
administering the drug or substance to the body vessel. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
