Vascular infusion device
First Claim
1. A vascular device for infusion of fluids into a patient comprising a first elongated tubular member having a proximal end, a distal end, at least a first lumen extending therethrough and a first wall having an outer surface and extending between said proximal end and said distal end, a second tubular member having a second wall, said second wall having at least one longitudinally disposed groove there in, and being positioned within said lumen to define a space between said first wall and said second wall, said space being adapted to receive a fluid, said second tubular member being sized and configured to create a fluid seal proximate said distal end of said second tubular member, and one or more apertures disposed in said first wall between said proximal end and said distal end for providing fluid communication between said space and an environment surrounding said outer surface of said first wall, wherein fluid interceded into said space exits said device substantially only through said one or more apertures along a length of said outer surface of said first wall.

Abstract
A vascular access device for infusion of fluids into a patient. The device includes an introducer sheath having one or more side holes and the sheath can be used with a catheter in place through the sheath, with a dilator in place through the sheath, or with the sheath vacant. The device provides for a significant volume of infused fluid to exit the side holes. The side holes allow for the infusion of fluids, such as medications, to be directed to specific patient locations rather than to have the entire volume of infused fluid exit the distal end of the sheath tube.

- 1. A vascular device for infusion of fluids into a patient comprising a first elongated tubular member having a proximal end, a distal end, at least a first lumen extending therethrough and a first wall having an outer surface and extending between said proximal end and said distal end, a second tubular member having a second wall, said second wall having at least one longitudinally disposed groove there in, and being positioned within said lumen to define a space between said first wall and said second wall, said space being adapted to receive a fluid, said second tubular member being sized and configured to create a fluid seal proximate said distal end of said second tubular member, and one or more apertures disposed in said first wall between said proximal end and said distal end for providing fluid communication between said space and an environment surrounding said outer surface of said first wall, wherein fluid interceded into said space exits said device substantially only through said one or more apertures along a length of said outer surface of said first wall.
- 17. A vascular device for infusion of fluids into a patient comprising a first elongated tubular member having a proximal end, a distal end and a lumen extending therethrough, a first wall extending between said proximal end and said distal end, with said first tubular member having a through opening at said distal end, a second tubular member having a second wall, said second wall having at least one longitudinally disposed groove there in, and being positioned within said lumen to define a space between said first wall and said second wall, said space being adapted to receive a fluid, with a portion of said second member extending through said opening at said distal end of said first tubular member, and one or more apertures disposed in said first wall between said proximal end and said distal end for providing fluid communication between said space and an environment external of said device, wherein a portion of said fluid introduced into said space exits said device through said one or more apertures along the length of said first wall.
- 19. A vascular device for infusion of fluids into a patient comprising a first elongated tubular member having a proximal end, a distal end and a lumen extending therethrough, and a first wall having an outer surface and extending between said proximal end and said distal end, a second tubular member having a second wall, said second wall having at least one longitudinally disposed groove there in, and being positioned within said lumen to define a space between said first wall and said second wall, said space being adapted to receive a fluid, and one or more apertures disposed in said first wall between said proximal end and said distal end for providing fluid communication between said space and an environment surrounding said outer surface of said first wall, wherein fluid introduced into said space exits said device substantially only through said one or more apertures alone the length of said outer surface of said first wall.
