Abstract
Medical devices for use in or on a mammalian body have improved properties through the use of magnetic pulse welding to join components. The improved properties include increased strength, corrosion resistance, and preservation of material characteristics. A method of forming a medical device using magnetic pulse welding is also provided.
Claims33
A medical device for use in or on a mammalian body comprising:
- a first component;
- a second component;
- and a connection formed between said first component and said second component, wherein said connection is formed by magnetic pulse welding.
A medical device for use in or on a mammalian body comprising:
- a first conductive, metallic component;
- and
- a second conductive, metallic component, wherein at least a portion of said first component and at least a portion of said second component are joined in a metallurgical bond without degradation of the metal of either component.
A method of assembling at least a portion of a medical device for use in or on a mammalian body comprising:
- providing a first component, a second component, and an inductor, wherein at least one of said first and second components is conductive;
- positioning at least a portion of said first component near at least a portion of said second component and in the vicinity of said inductor;
- and
- supplying a current pulse to the inductor to generate a magnetic field, thereby causing at least a portion of said first component to form a connection with at least a portion of said second component by magnetic pulse welding.
A method of assembling at least a portion of a medical device for use in or on a mammalian body comprising:
- providing a first component, a second component, and an inductor, wherein at least one of said first and second components is conductive;
- positioning at least a portion of said first component near at least a portion of said second component and in the vicinity of said inductor;
- and
- explosively compelling one of said first and second components towards the other of said components through the use of a magnetic field so as to form a connection between the first and second components.
A method of assembling at least a portion of a medical device for use in or on a mammalian body comprising:
- providing a first component made of a material, a second component made of a material, and an inductor, wherein at least one of said first and second components is conductive;
- positioning at least a portion of said first component near at least a portion of said second component and in the vicinity of said inductor;
- and
- compelling one of said first and second components towards the other of said components through the application of a magnetic field created by said inductor, without substantially heating or degrading the material of either of said first and second components.
