Medical device bending tool
A method and system of bending medical device components for customization to a particular medical procedure and patient while generally maintaining the ideal performance of the component. A medical professional embeds the medical device component into a bending tool. The medical professional then aligns an intended curve region of the medical device component within a bending region of the bending tool and imparts a curve in the bending region. Finally, the medical professional withdraws the medical device component from the bending tool, and utilizes the bent medical device component in the medical procedure. The system may be a kit comprising various medical device components for a particular medical procedure and a suitable bending tool for those components.
1. A method of bending a medical device component for use in a contemporaneous or shortly succeeding medical procedure, the method comprising:
inserting the medical device component into a bending tool,
bending the bending tool and the medical device component,
removing the bent medical device component from the bending tool, and
utilizing the bent medical device component in the medical procedure;
wherein after the removing step, comparing the bent medical device component to a bending template and determining if the bent medical device is bent to a lesser angle than a maximum angle displayed on the bending template indicating that the user can bend the medical device component again if needed.
2. The method of claim 1 wherein:
the bending tool is a bending spring.
3. The method of claim 1 wherein:
the medical device component is selected from a group consisting of: a cannula, a catheter, and a needle.
4. The method of claim 1 further comprising:
before the inserting step, determining a desired bend shape and location using a medical imaging technique.
5. The method of claim 1 further comprising:
the bending tool comprises a steel alloy.
6. The method of claim 1 wherein:
the medical procedure is a transjugular intrahepatic portosystemic shunt procedure.
7. The method of claim 1 further comprising:
repeating the inserting, bending, removing, and comparing steps until a desired bend is achieved.
8. The method of claim 1 wherein:
the bending tool comprises a helical coil of wire.
9. The method of claim 1 further comprising:
after the bending step, the bending tool is twisted along a central axis to apply a torsional force to increase the distance between the bending tool and the medical device component, wherein the increased distance reduces friction between the medical device component and the bending tool, easing the removal of the component.
10. The method of claim 1 further comprising:
prior to the bending step, placing a fulcrum at a desired bending location, and applying a first force and a second force generally opposite the location of the fulcrum, where the first force is spaced apart from the fulcrum towards a first end of the bending tool and the second force is spaced apart from the fulcrum towards a second end of the bending tool.
11. The method of claim 10 wherein:
the fulcrum is a user's thumb.
12. The method of claim 1 wherein:
the bending tool is adapted to fit a 14 gauge cannula.
13. The method if claim 1 wherein:
the bending tool is adapted to fit a 16 gauge needle.
14. A method of producing a curve in a medical device component for use in a contemporaneous or shortly succeeding medical procedure comprising:
embedding the medical device component into a bending tool,
aligning an intended curve region of the medical device component within a bending region of the bending tool,
producing a curve in the intended curve region of the medical device component,
withdrawing the bent medical device component from the bending tool, and
utilizing the bent medical device component in the medical procedure;
wherein prior to the producing a curve step, placing a fulcrum at the intended curve region of the medical device component, and applying a first force and a second force generally opposite the location of the fulcrum, where the first force is spaced apart from the fulcrum towards a first end of the bending tool and the second force is spaced apart from the fulcrum towards a second end of the bending tool.
