Patent ID: 8486155

Claim:
A surgical device for coextruding a multilayered biocompatible tissue repair plug in situ within a lumen in a patient, the device comprising: (a) a handle; (b) a shaft extending distally away from the handle, the shaft having a distal end; (c) a plurality of conduits extending through at least a portion of the shaft to the distal end of the shaft, wherein each of the is in communication with an orifice at the distal end of the shaft for expelling material therefrom, wherein each of the orifices at the distal end of the shaft terminates at the same longitudinal distance from the handle, wherein each of the orifices are coaxially positioned in relation to each other wherein the plurality of conduits comprise: (i) a first sleeve, wherein the first sleeve is in communication with one of the plurality of conduits, and (ii) a second sleeve, wherein the second sleeve is further in communication with another of the plurality of conduits, wherein the first sleeve and the second sleeve are adjacently positioned at the distal end of the shaft, wherein the first sleeve and the second sleeve are further coaxially positioned in relation to each other; (d) a plurality of media chambers, wherein each media chamber is in communication with a corresponding one of the conduits, at least one of the media chambers containing a suspension of at least one tissue fragment having at least one viable cell in a biocompatible carrier; and (e) an actuator operable to cause media in each of the chambers to be urged through, and expelled from the orifice of, the conduit in communication therewith; wherein the orifices are located at the distal end of the shaft such that media from the media chambers may be ejected into a lumen in a patient in order to form a multilayered biocompatible tissue repair plug in situ.
