Abstract

Arrangements and methods for delivering bioactive agents and/or cells into an extended volume of tissue are disclosed. In one embodiment, a cell-delivering needle arrangement has a tube positioned within a tube and fixedly attached to a wall thereof. In one exemplary method, a cell-delivering needle is advanced into tissue, a suspension of cells is passed through a first lumen and out of side ports, and a suspension of cells is passed through a second lumen and out of a distal opening. Other embodiments are disclosed.

First claim

1 . A needle, comprising:
a needle body having a proximal end region, a distal end region, and a sidewall; said needle body defining a first lumen extending from said proximal end region to said distal end region; said first lumen terminating in a closed distal end and communicating with a plurality of ports defined by said sidewall; said needle body defining a second lumen extending from said proximal end region to said distal end region and communicating with a distal opening in said distal end region; and said distal end region having a tissue-penetrating tip.

2 . The needle of claim 1 , wherein:
said first lumen and said second lumen are fixedly positioned to one another.

3 . The needle of claim 1 , wherein:
said ports are positioned around the periphery of said needle body.

4 . The needle of claim 1 , wherein:
said ports have a cross-sectional area that is smaller than a cross-sectional area of said distal opening.

5 . The needle of claim 1 , wherein:
said second lumen has a cross-sectional area that is smaller than a cross-sectional area of said first lumen.

6 . The needle claim 1 , wherein:
said second lumen is positioned within said first lumen.

7 . The needle of claim 6 , wherein:
said second lumen is surrounded by an annular space.

8 . The needle of claim 1 , wherein:
a distal end of said second lumen extends beyond a distal end of said first lumen.

9 . The needle of claim 1 , further comprising:
a plug closing the distal end of said first lumen.

10 . A fluid delivering needle, comprising:
a needle body having a proximal end region, a distal end region, a first elongated body, and a second elongated body; said first elongated body having a sidewall defining a first lumen extending from said proximal end region to said distal end region; said first lumen terminating in a closed distal end and communicating with a plurality of ports defined by said sidewall and positioned around the periphery of said first elongated body; said second elongated body positioned within said first lumen and fixedly coupled to a wall thereof; said second elongated body defining a second lumen extending from said proximal end region to said distal end region and communicating with a distal opening in said distal end region; and said distal end region of said needle body having a tissue-penetrating needle tip.

11 . The needle of claim 1 , wherein:
said plurality of ports are longitudinally spaced along a length of said needle body.

12 . The needle of claim 10 , wherein:
said plurality of ports are longitudinally spaced along a length of said needle body.

13 . The needle of claim 1 , further comprising:
a connector in the proximal end region, the connector having a first coupling portion and a second coupling portion; said first coupling portion arranged to fluidly couple a first syringe with said first lumen; and said second coupling portion arranged to fluidly couple a second syringe with said second lumen.

14 . The needle of claim 10 , further comprising:
a connector in the proximal end region, the connector having a first coupling portion and a second coupling portion; said first coupling portion arranged to fluidly couple a first syringe with said first lumen; and said second coupling portion arranged to fluidly couple a second syringe with said second lumen.

15 . The needle of claim 1 , wherein:
said plurality of side ports includes one or more side ports of different size.

16 . The needle of claim 10 , wherein:
said plurality of side ports includes one or more side ports of different size.

17 . The needle of claim 1 , wherein:
said needle body is arranged to deliver fluid from said plurality of ports at a higher velocity than fluid exiting said distal opening.

18 . The needle of claim 10 , wherein:
said needle body is arranged to deliver fluid from said plurality of ports at a higher velocity than fluid exiting said distal opening.

19 . The needle of claim 10 , wherein:
said plurality of ports each have a cross-sectional area that is smaller than a cross-sectional area of said distal opening.

20 . The needle of claim 10 , wherein:
said second lumen has a cross-sectional area that is smaller than a cross-sectional area of said first lumen.
