Abstract

An implantation instrument for implanting a substantially solid material, including solid medication or drugs, in a subcutaneous location and method are described. An incising shaft includes a beveled tip with a cutting edge along a distal end. A syringe body is affixed to a proximal end of the incising shaft. The syringe body and the incising shaft each define a substantially non-circular hollow bore extending continuously along a shared longitudinal axis. The incising shaft bore does not exceed the syringe body bore in girth. Both the incising shaft bore and the syringe body bore are sized to receive the solid material. A plunger is conformably shaped to the syringe body bore and has an end piece facilitating deployment of the plunger assembly. The plunger slidably fits within the syringe body bore and advances the solid material through the syringe body bore and the incising shaft bore into the subcutaneous location.

Claims

1. (canceled)

2. A subcutaneous implantation instrument, comprising:

an incising shaft longitudinally defining a substantially non-circular bore continuously formed to communicatively receive an implantable object and further comprising a beveled cutting blade formed on a distal end; and

a delivery mechanism longitudinally defining a substantially non-circular bore formed to deploy the implantable object into the incising shaft.

3. A subcutaneous implantation instrument in accordance with claim 2, wherein the incising shaft is formed into a curve arced towards the delivery mechanism.

4. A subcutaneous implantation instrument in accordance with claim 2, wherein the cutting blade further comprises a rounded tip.

5. A subcutaneous implantation instrument in accordance with claim 2, wherein the implantable object is selected from the group comprising medical monitoring and diagnostic devices, non-medical monitoring devices, data collection monitors, medical therapeutic devices, solid objects, and semi-solid objects.

6. A method for constructing a subcutaneous implantation instrument, comprising:

providing an incising shaft longitudinally defining a substantially non-circular bore continuously formed to communicatively receive an implantable object and further comprising a beveled cutting blade formed on a distal end; and

affixing a delivery mechanism to the incising shaft and longitudinally defining a substantially non-circular bore formed to deploy the implantable object into the incising shaft.

7. A method in accordance with claim 6, further comprising:

forming the incising shaft into a curve arced towards the delivery mechanism.

8. A method in accordance with claim 6, wherein the cutting blade further comprises a rounded tip.

9. A method in accordance with claim 8, wherein the implantable object is selected from the group comprising medical monitoring and diagnostic devices, non-medical monitoring devices, data collection monitors, medical therapeutic devices, solid objects, and semi-solid objects.

10. A subcutaneous implantation instrument package, comprising:

a non-liquid implantable object; and

a subcutaneous implantation instrument packaged with the non-liquid implantable object, comprising;

an incising shaft longitudinally defining a substantially non-circular bore continuously formed to communicatively receive the implantable object and further comprising a beveled cutting blade formed on a distal end; and

a delivery mechanism longitudinally defining a substantially non-circular bore formed to deploy the implantable object into the incising shaft.

11. A subcutaneous implantation instrument package in accordance with claim 10, wherein the incising shaft is formed into a curve arced towards the delivery mechanism.

12. A subcutaneous implantation instrument package in accordance with claim 10, wherein the cutting blade further comprises a rounded tip.

13. A subcutaneous implantation instrument package in accordance with claim 10, wherein the implantable object is selected from the group comprising medical monitoring and diagnostic devices, non-medical monitoring devices, data collection monitors, medical therapeutic devices, solid objects, and semi-solid objects.

14. A method for constructing a subcutaneous implantation instrument package, comprising:

selecting a non-liquid implantable object; and

packaging a subcutaneous implantation instrument, comprising;

fashioning an incising shaft longitudinally to define a substantially non-circular bore continuously formed to communicatively receive the implantable object and further comprising a beveled cutting blade formed on a distal end; and

providing a delivery mechanism to longitudinally define a substantially non-circular bore formed to deploy the implantable object into the incising shaft.

15. A method in accordance with claim 14, further comprising:

forming the incising shaft into a curve arced towards the delivery mechanism.

16. A method in accordance with claim 14, wherein the cutting blade further comprises a rounded tip.

17. A method in accordance with claim 14, wherein the implantable object is selected from the group comprising medical monitoring and diagnostic devices, non-medical monitoring devices, data collection monitors, medical therapeutic devices, solid objects, and semi-solid objects.

18. A method for implanting a non-liquid object, comprising:

forming a subcutaneous implantation site by urging a subcutaneous implantation instrument that comprises an incising shaft with a beveled cutting blade formed on a distal end subdurally to a predetermined depth, wherein the incising shaft longitudinally defines a substantially non-circular bore;

deploying a non-liquid object into the subcutaneous implantation site by progressively urging a delivery mechanism distally through a syringe body proximally affixed to the incising shaft to deploy the implantable object into the incising shaft and thence to insert the implantable object into the subcutaneous implantation site; and

withdrawing the incising shaft from the subcutaneous implantation site, which is subsequently closed.

19. A method in accordance with claim 18, wherein the incising shaft is formed into a curve arced towards the incising shaft.

20. A method in accordance with claim 18, further comprising:

withdrawing the incising shaft partway out of the subcutaneous implantation site prior to deploying the non-liquid object.

21. A method in accordance with claim 18, wherein the implantable object is selected from the group comprising medical monitoring and diagnostic devices, non-medical monitoring devices, data collection monitors, medical therapeutic devices, solid objects, and semi-solid objects.

22. A method in accordance with claim 18, wherein the subcutaneous implantation site comprises a site that is at least one of intramuscular, submuscular, within a body cavity, including intrathoracic.
