Abstract
A medically implantable electrical connector includes a housing having a bore with an internal V-groove or a flat bottom groove therein along with radial garter spring disposed in the V-groove or an axial garter spring disposed in the flat bottom groove. A pin is provided and sized for insertion in the housing bore. The housing, spring and pin are formed from a combination of medically implantable materials in order to control electrical resistivity between the housing, the garter spring and the pin.
Claims20
A medically implantable electrical connector comprising:
- a housing having a bore with an internal V-groove therein;
- a radial garter spring disposed in said V-groove;
- and
- a pin sized for insertion into the housing bore;
- said housing, spring and pin being formed from a combination of medically implantable materials in order to control electrical resistivity between said housing, said garter spring and said pin.
A medically implantable electrical connector comprising:
- a housing having a bore with an internal flat bottomed groove therein;
- an axial garter spring disposed in said groove;
- and
- a pin sized for insertion into the housing bore;
- said housing, spring and pin being formed from a combination of medically implantable materials in order to control electrical resistivity between said housing, said garter spring and said pin.
A medically implantable electrical connector comprising:
- a housing having a bore with an internal V-groove therein;
- a radial garter spring disposed in said V-groove;
- and
- a pin sized for insertion into the housing bore, said pin including an external groove for capturing said spring in order to removably latch said in within the housing bore, said latch providing a disconnect force and a connect force;
- and
- said housing, spring and pin being formed from a combination of medically implantable materials in order to control electrical resistivity between said housing, said garter spring and said pin.
The connector according to class 15 wherein a ratio of disconnect force to connect force is between about 1 to 1 and about 10 to 1.
