Abstract
An injection needle including a guide portion configured to have a first outer diameter, and a delivery portion, configured with a tip to penetrate tissue and deliver a medication, and to have a second outer diameter smaller than the first outer diameter, extending from a distal end of the guide portion, wherein the guide portion is configured to have a bend proximate the distal end such that the delivery portion extends at a predetermined angle from a line of the guide portion opposite the bend.
Claims24
An injection needle, comprising:
- a guide portion configured to have a first outer diameter;
- and
- a delivery portion, configured with a tip to penetrate tissue and deliver a medication, and to have a second outer diameter smaller than the first outer diameter, extending from a distal end of the guide portion;
- wherein the guide portion is configured to have a bend proximate the distal end such that the delivery portion extends at a predetermined angle from a line of the guide portion opposite the bend.
1 more element
An injection needle, comprising:
- a first needle portion having a first outer diameter;
- and
- a second needle portion having a second outer diameter, the second outer diameter being smaller than the first outer diameter,
- wherein the second needle portion has a tip configured to penetrate a soft tissue.
1 more element
An injection needle, comprising:
- a hub portion configured to mate with a corresponding hub portion of a medication delivery device;
- a needle attached at a proximal end to the hub and configured to have a first outer diameter extending in a longitudinal direction from the hub, the first outer diameter having a bend portion proximate a distal end of the needle, the bend portion having a predetermined angle matching a corresponding tissue path through which the needle will pass to enter a targeted region of the patient, the needle including a distal end configured to have a second outer diameter smaller than the first outer diameter, the second diameter terminating to a needle tip for delivery of medication into the targeted region, the first diameter being specifically sized to push away bodily tissue in the tissue path a distance sufficient to provide an opening for the second diameter to enter the targeted region at the predetermined angle to deliver medication to the targeted region.
