Patent ID: 8241302

Claim:
A guide device for guiding a medical instrument relative to a patient, the guide device being usable with a first plate and a second plate, wherein the first plate has a plurality of apertures, wherein the second plate and the first plate are adjustable to secure a portion of the patient, wherein the guide device is configured to be coupled with a selected one of the apertures of the first plate, the guide device comprising: a. a body defined by at least one surface, wherein the body comprises a proximal portion and a distal portion; b. at least one passageway, wherein the at least one passageway extends from the proximal portion through the body and to the distal portion, wherein the at least one passageway is configured to receive at least a portion of the medical instrument; and c. an interface portion associated with the at least one surface of the body, wherein the interface portion is configured to be coupled with an inner portion of the first plate defining the selected one of the plurality of apertures, wherein the interface portion forms a taper from the proximal portion of the body to the distal portion of the body, wherein the interface portion comprises a plurality of elastomeric protrusions protruding from the at least one surface of the body to maintain a height outward of and above the at least one surface such that the plurality of elastomeric protrusions cannot be biased into a position below the at least one surface of the body, wherein the elastomeric protrusions progressively increase in size from the proximal portion of the body to the distal portion of the body to form the taper with respect to one another.
