A sensor assembly for use in a surgical procedure is described. The assembly can includes a sensor for implantation into a body part, a sensor cord attached to and extending from the sensor and a handle fastened to the sensor cord. The handle is fastened so that a force can be applied to the sensor cord via the handle. The handle comprises a force indicator to which force applied to the sensor cord is applied and which can provide an indication of the force applied to the sensor cord via the handle.

The invention claimed is: 1. A sensor handle assembly for use in a surgical procedure, comprising: a sensor configured to be implanted into a body part; a sensor cord attached to and extending from the sensor; a handle having an inlet, an outlet and a recess; and a component sized and configured to be disposed in the recess at a location between the inlet and the outlet, and wherein a continuous portion of the sensor cord is disposed through the inlet and around the component, such that the length of sensor cord disposed within the recess is greater than the distance measured from the inlet to the outlet, and wherein the component is configured to break when a force exceeding a predetermined force is exerted on the component. 2. The sensor handle assembly of claim 1, wherein the component is configured to provide an indication that can be felt by the user holding the handle when the force exceeding the predetermined force is exerted on the component. 3. The sensor handle assembly of claim 1, wherein the component is configured to cause a reduction in the force applied to the sensor cord via the handle when the force exceeding the predetermined force is exerted on the component. 4. The sensor handle assembly of claim 1, wherein the component has a line of weakness that is configured to break when the force exceeding the predetermined force is exerted on the component. 5. The sensor handle assembly of claim 1, wherein the component is formed separately from the handle. 6. The sensor handle assembly of claim 1, wherein the recess of the handle defines a first wall and a second wall and the component is a pin that extends between the first wall and the second wall. 7. The sensor handle assembly of claim 1, wherein the continuous portion of the sensor cord is disposed through the inlet, around the component and through the outlet. 8. The sensor handle assembly of claim 1, wherein recess forms a channel within which the continuous portion of the sensor cord is disposed, and, when so disposed, a portion of the continuous portion that is disposed within the inlet and around component bends at least 90 degrees within the recess prior to contacting the component. 9. The sensor handle assembly of claim 1, wherein the component comprises a body, a first arm extending from a first end of the body, and a second arm extending from a second end of the body, and wherein at least one of the first arm and second arm are configured to be structurally weaker than the body. 10. The sensor handle of claim 9, wherein the body has a body diameter, and the first arm has a first diameter and the second arm has a second diameter, and at least one of the first diameter and the second diameter is smaller than the body diameter. 11. The sensor handle assembly of claim 1, wherein the predetermined force is approximately equal to the tear force of the sensor cord. 12. The sensor handle assembly of claim 1, wherein the handle is configured to receive a second cord. 13. The sensor handle assembly of claim 12, wherein the handle and second cord are associated with one another such that a force can be applied to the second cord via the handle. 14. The sensor handle assembly of claim 13, wherein the handle, the component and the second cord are configured such that any force applied to the second cord is not applied to the component. 15. The sensor handle assembly of claim 1, wherein the sensor includes at least one sensing coil that can generate a signal in response to an electromagnetic field, the sensor cord includes at least one wire connected to an external device for receiving signals from the sensor, and the assembly further comprises: a patch transmitter for generating the electromagnetic field; and a patch cord, attached to and extending from the patch transmitter. 16. The sensor handle assembly of claim 15, wherein at least a portion of the patch cord is disposed within the handle. 17. The sensor handle assembly of claim 16, wherein the patch cord is clamped to the handle.
