Abstract
An injection needle includes a first needle portion defining a first outer diameter, a second needle portion defining a second outer diameter that is smaller than the first outer diameter, the second needle portion having a tip configured to penetrate a soft tissue. Importantly, the first end of the second needle portion is positioned substantially inside and coupled to an inner surface of the first needle portion adjacent an angled section that is positioned adjacent a distal end of the first needle portion. In addition, the first and second needle portions may be crimped or pinched together into a unitary construction that still allows a pharmaceutical to pass therethrough.
Claims17
An injection needle, comprising:
- a first needle portion having proximal and distal ends and having a tubular configuration that defines a first outer diameter;
- a second needle portion having first and second ends and having a tubular configuration that defines a second outer diameter that is smaller than the first outer diameter, said first end being positioned intermediate said proximal and distal ends of said first needle portion, said second needle portion having a tip coupled to said second end and configured to penetrate a soft tissue of a patient;
- wherein said first needle portion forms an angled section at a point intermediate the proximal and distal ends thereof;
- wherein said first needle portion includes a linear configuration upstream of said angled section and second needle portion includes a linear configuration downstream of said angled section;
- wherein said first end of said second needle portion is positioned upstream of said angled section of said first needle portion.
An injection needle for use on a patient, comprising:
- a hub configured to mate with a corresponding hub portion of a medication delivery device;
- a first needle portion having a proximal end in fluid communication with said hub and a distal end opposite said proximal end, said first needle portion having a tubular configuration that defines a first outer diameter extending in a longitudinal direction away from the hub;
- said first needle portion having a bend section intermediate said proximal and distal ends, the bend section having a predetermined angle configured to match a corresponding tissue path through which the first needle portion will pass to enter a targeted region of the patient;
- a second needle portion having first and second ends and having a tubular configuration that defines a second outer diameter that is smaller than the first outer diameter, said first end being positioned intermediate said proximal and distal ends of said first needle portion,
- wherein said first needle portion has a linear configuration upstream of said bend portion and said second needle portion has a linear configuration downstream of said bend portion;
- wherein said first end of said second needle portion is positioned upstream of said bend section of said first needle portion;
- said second end of said second needle portion terminating at a tip configured to penetrate a soft tissue of the patient.
