Abstract
Abstract A device for injecting medication into a vessel wall includes an inflatable balloon mounted on a catheter. Additionally, a tubular sleeve surrounds the balloon to create an infusion chamber between the sleeve and the balloon, and a plurality of injectors are mounted on the sleeve in fluid communication with the infusion chamber. During use of the device, the balloon is first positioned in a vessel and then inflated to embed the injectors into the vessel wall. Next, a fluid medicament is introduced into the infusion chamber for further infusion from the chamber and through the injectors into the vessel wall.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
70 words
A device for injecting fluid medication into the wall of a vessel which comprises: a fluid source; means for penetrating said vessel wall; inflatable means for holding said penetrating means; means interconnecting said fluid source with said penetrating means for establishing fluid communication therebetween; and means for inflating said holding means to move said penetrating means toward said vessel wall for penetration of said penetrating means into said arterial wall.
Claim 2
Dependent Claim
16 words
A device as recited in claim 1 wherein said penetrating means includes at least one injector.
Claim 3
Dependent Claim
63 words
A device as recited in claim 2 wherein said injector comprises: a base; and a hollow protrusion having a first end and a second end, said protrusion projecting from said base to establish a fluid channel through said base and through said protrusion, said first end of said protrusion being affixed to said base and said second end formed with a cutting edge.
Claim 4
Dependent Claim
14 words
A device as recited in claim 2 which comprises a plurality of said injectors.
Claim 5
Dependent Claim
15 words
A device as recited in claim 1 wherein said holding means is an inflatable balloon.
Claim 6
Dependent Claim
16 words
A device as recited in claim 5 wherein said balloon is made of polyethylene terephthalate (PET).
Claim 7
Dependent Claim
48 words
A device as recited in claim 1 wherein said fluid communication establishing means includes a tubular sleeve having a proximal end and a distal end, said distal end of said tubular sleeve being surroundingly mounted over a portion of said holding means to create an infusion chamber therebetween.
Claim 8
Dependent Claim
17 words
A device as recited in claim 7 wherein said tubular sleeve is made of polyethylene terephthalate (PET).
Claim 9
Dependent Claim
34 words
A device as recited in claim 7 further comprising means connected with said proximal end of said tubular sleeve for injecting medication into said infusion chamber and through said injector into the vessel wall.
Claim 10
Independent Claim
117 words
A device for injecting medication into the wall of a vessel which comprises: an inflatable balloon; a tubular sleeve having a proximal end and a distal end, said distal end of said tubular sleeve being surroundingly mounted over a portion of said balloon to create an infusion chamber therebetween; at least one injector mounted on said tubular sleeve with said sleeve positioned between said injector and said balloon, said injector being in fluid communication with said infusion chamber; means for inflating said balloon to embed said injector into the vessel wall; and means connected with said proximal end of said tubular sleeve for injecting medication into said infusion chamber and through said injector into the vessel wall.
Claim 11
Dependent Claim
63 words
A device as recited in claim 10 wherein said injector comprises: a base; and a hollow protrusion having a first end and a second end, said protrusion projecting from said base to establish a fluid channel through said base and through said body, said first end of said protrusion being affixed to said base and said second end formed with a cutting edge.
Claim 12
Dependent Claim
18 words
A device as recited in claim 11 further comprising a plurality of said protrusions projecting from said base.
Claim 13
Dependent Claim
13 words
A device as recited in claim 12 which comprises a plurality of injectors.
Claim 14
Dependent Claim
14 words
A device as recited in claim 11 wherein said protrusion is substantially cylindrical shaped.
Claim 15
Dependent Claim
14 words
A device as recited in claim 11 wherein said protrusion is substantially conical shaped.
Claim 16
Dependent Claim
39 words
A device as recited in claim 10 which further comprises: a guidewire; a catheter formed with a plurality of lumens, one said lumen being dimensioned to receive said guidewire therethrough for guiding and positioning said balloon in said vessel.
Claim 17
Dependent Claim
24 words
A device as recited in claim 16 wherein one said lumen of said catheter establishes fluid communication between said balloon and said inflating means.
Claim 18
Dependent Claim
25 words
A device as recited in claim 10 wherein said inflatable balloon is made of polyethylene terephthalate (PET) and said tubular sleeve is made of polyurethane.
