Substance delivery apparatus and a method of delivering a therapeutic substance to an anatomical passageway
First Claim
1. A method of administering a substance, comprising:
- inserting a catheter assembly into a biological passageway of a subject, said catheter assembly includinga balloon disposed at an end portion of said catheter assembly, said balloon being configured to have a collapsed form and an expanded form,a needle capable of penetrating into tissues of a subject for administering a substance to said subject, anda hollow body in fluid communication with said needle, said hollow body being defined by a first section and a second section, wherein said first section is capable of pivotally rotating with respect to said second section in response to inflation of said balloon from said collapsed form to said expanded form, and wherein a longitudinal axis of said needle is generally parallel to a longitudinal axis of said balloon when said balloon is in said collapsed form;
positioning said balloon at a desired area of said passageway;
expanding said balloon so as to pivotally rotate said first section for penetrating said needle into a wall of said desired area; and
supplying said substance through said hollow body of said catheter assembly to administer said substance to said desired area.

Abstract
A catheter assembly is provided having a balloon disposed at the distal end thereof. The balloon is capable of being inflated to selectively dilate from a collapsed configuration to an expanded configuration. A syringe assembly is in fluid communication with a delivery lumen of the catheter assembly for allowing a therapeutic substance to be injected into a tissue of a passageway. The syringe assembly includes a portion capable of pivoting from a first position towards a second position when the balloon is being inflated from the collapsed configuration to the expanded configuration. The portion of the syringe assembly is also capable of pivoting from the second position back towards the first position when the balloon is being deflated.

7. A method of administering a substance, comprising:
-
inserting a catheter assembly into a lumen of a subject, said catheter assembly comprising a balloon integrated with said catheter assembly, wherein said balloon is capable of being inflated to selectively dilate from a collapsed configuration to an expanded configuration and said balloon is capable of being deflated after inflation to retract to a deflated profile, and a needle, for delivering said substance, integrated with said catheter assembly, wherein said needle is essentially parallel to the direction of movement of said catheter assembly in said lumen when said balloon is in said collapsed configuration and said needle is positioned at an angle with respect to a longitudinal axis of said balloon when said balloon is in an expanded configuration; positioning said needle at a desired area; expanding said balloon to cause said needle to enter said lumen; and administering said substance to said subject. - View Dependent Claims (8, 9, 10, 11, 12)
