## Abstract

A multiple-use connection system includes an elongate body having an axial tail-receiving passage and having lengthwise sides, and at least two essentially parallel rows of axially-spaced pin receptacles transverse to the tail-receiving passage, the pin receptacles of one of the parallel rows being exposed along one of the lengthwise sides. A patchbay for selectively connecting pairs of connector pins with ones of a plurality of tail conductors includes an insulating body having an axial passageway adapted for receiving a tail and having pairs of aligned pin receptacles, the pairs of pin receptacles being axially spaced from one another, one pin receptacle of each of the pairs of pin receptacles having an exposed portion adapted for being directly probed, where selective placement of pairs of aligned pins into the insulating body effects electrical connection of a pair of pins to a selected one of the tail conductors.

## Claims

### Claim 1

In a method for electrical monitoring of a plurality of locations of the brain including (a) temporarily implanting an electrode array which has a connector-engaging multiconductor annular-ring-type tail, (b) inserting the tail into an axially extending tail-receiving passage of a connector body that also includes first and second rows of pin-receptacle spaces on either side of the axis, each space being substantially orthogonal to and intersecting with the tail-receiving passage, such pin-receptacle spaces extending into the connector body from a first lengthwise surface thereof, and (c) inserting pins of a plug into the pin-receptacle spaces such that pairs of connecting pins engage corresponding conductor rings of the tail, the improvement comprising: providing a plurality of access holes along a second lengthwise surface of the connector body, each access hole extending from the second elongate lengthwise surface to the tail-receiving passage to provide electrical access to a corresponding one of the conductor rings of the tail; and applying a stimulus to a selected point of the brain by inserting a stimulating probe into corresponding adjacent access openings.

### Claim 2 (depends on 1)

The method of claim 1 wherein the second lengthwise surface is adjacent to the first lengthwise surface such that the access holes provide access to one of the rows of pins.

### Claim 3 (depends on 1)

The method of claim 1 further comprising applying a stimulus to the brain by directly contacting two of the exposed pins with a bipolar stimulating probe.
