Abstract
A precision steerable and angled medication delivery system and methods of using the same are disclosed. The medication delivery system may include a syringe, a connector orientation structure, and a flexible needle. The system may direct a delivery mechanism in connection with a control syringe to delivery sites within a patient's body. In this manner, therapeutic injections may be performed at precise locations as desired.
Claims27
A method of directionally controlled medication delivery by a medical professional using a precision steerable and angled medication delivery system, the method comprising:
- inserting a flexible needle into an external skin surface of a patient's skin and into the patient's subcutaneous tissue at an external entry point on the patient's body;
- steering the flexible needle along a curved path through intervening subcutaneous tissue to a delivery site;
- and
- delivering at least a portion of a medication from the flexible needle to the delivery site, wherein the precision steerable and angled medication delivery system includes:
- a control syringe comprising a syringe body generally aligned along a first longitudinal axis and having a first end and a second end, and a connector orientation structure positioned at the second end of the syringe body and in fluid communication with the syringe body,
- the flexible needle having a first end and a second end, a second longitudinal axis defined between the first end of the flexible needle and the second end of the flexible needle, the flexible needle having a length between the first end of the flexible needle and the second end of the flexible needle that is between about 1.5 inches and about 6 inches, wherein the first end of the flexible needle is positioned adjacent the connector orientation structure and in fluid communication with the control syringe via the connector orientation structure,
- wherein the connector orientation structure is configured to position the needle such that the second longitudinal axis of the flexible needle is angled relative to the first longitudinal axis of the syringe body such that the second longitudinal axis of the flexible needle and the first longitudinal axis of the syringe body define an angle between the respective longitudinal axes that is at least about 60 degrees,
- wherein the flexible needle is configured to be steerable along the curved path in the patient's subcutaneous tissue in response to rotation of the syringe body of the control syringe about the first longitudinal axis,
- wherein a portion of a hand of the medical professional is positioned on an external body part of the patient in an anchor position to assist with the steering of the flexible needle along the curved path in the patient's subcutaneous tissue by movement of the hand of the medical professional.

A method of directionally controlled liquid delivery by a medical professional using a precision steerable and angled liquid delivery system, the method comprising:
- inserting a flexible needle into an external skin surface of a patient's skin and into the patient's subcutaneous tissue at an entry point on the patient's body;
- steering the flexible needle through intervening subcutaneous tissue of the patient along a curved path to a delivery site;
- and
- delivering a liquid from the flexible needle to the delivery site,
- wherein the precision steerable and angled liquid delivery system includes:
- a control syringe having a first end and a second end and a longitudinal axis defined between the first end and the second end of the control syringe, the control syringe comprising:
- a syringe body having a reservoir for a liquid and a grip, wherein the grip includes a first member and a second member disposed on opposite sides of the syringe body to each receive a finger;
- and
- a plunger insertable into the reservoir to expel the liquid;
- and
- an angled connector body with a first end and a second end and a second longitudinal axis defined between the first end of the angled connector body and the second end of the angled connector body, the second end of the angled connector body configured to couple to the flexible needle that has a length of at least about 1.5 inches to about 6 inches and to align at least a portion of the flexible needle along the second longitudinal axis, such that a fixed angle measured between the longitudinal axis of the control syringe and the second longitudinal axis of the angled connector body is about 60 degrees to about 120 degrees, and
- wherein the angled connector body comprises a volume defined through the angled connector body and provides fluid communication between the reservoir of the control syringe and the flexible needle;
- wherein the flexible needle is configured to be steerable within soft tissue of the patient along the curved path in the subcutaneous tissue in response to rotation of the control syringe about the longitudinal axis of the control syringe, and
- wherein a portion of a hand of the medical professional is positioned on an external body part of the patient in an anchor position to assist with the steering of the flexible needle along the curved path in the patient's subcutaneous tissue by movement of the hand of the medical professional.
