Abstract:
1. A tissue collection apparatus comprising: a substantially cylindrical body having an open proximal end, an internal surface, a proximal surface and a closed end, said substantially cylindrical body further includes a detachable closure cap having a first portion of a size and shape adapted to receive a first connection tube, said detachable closure cap is of a shape and dimension to seal hermetically said open proximal end so as to prevent the flow of air at the juncture thereof and said substantially cylindrical body, said first portion includes a first internal passage for allowing a collection of bone growth elements substantially having platelets, mesenchymal cells, bone cells, blood and tissue cells, collagen and noncollagenous proteins comprising components thereof to flow through said first connection tube, said first internal passage and into said substantially cylindrical body, the collection of bone growth elements includes a proximal tissue surface and a peripheral tissue margin; an interpositional admixture element having a proximal extent and a distal portion adapted to receive the collection of bone growth elements and define a peripheral portion at the juncture thereof and said proximal extent, said interpositional admixture element includes a proximal facing tissue surface and a distal facing chamber surface, said interpositional admixture element further includes means for initiating bone formation therewithin the collection of bone growth elements, said means comprising a plurality of surface gaps having a size adapted to induce clot formation therewithin the collection of bone growth elements, said plurality of surface gaps ensure a passageway therebetween said proximal facing tissue surface and said distal facing chamber surface of said interpositional admixture element, said interpositional admixture element is operationally interposed therebetween said detachable closure cap, said internal surface and said closed end so as to ensure that the collection of bone growth elements strike an area of contact along a surface plane of said peripheral portion, said interpositional admixture element is further interposed so as to establish a tissue chamber proximally and an air chamber distally within said substantially cylindrical body, said interpositional admixture element is of a shape and dimension to ensure at all times a vacuum path of least resistance, said vacuum path of least resistance comprising said tissue chamber, said plurality of surface gaps throughout said peripheral portion and said air chamber, said interpositional admixture element is further of a size and dimension so as to induce a gravitational flow of the collection of bone growth elements along said surface plane, the gravitational flow is of a magnitude to induce mixing of components of the collection of bone growth elements; and a second portion operationally disposed thereabout said substantially cylindrical body, said second portion is of a size and shape adapted for mounting vacuum means, said vacuum means inducing a flow of air through said vacuum path of least resistance, said vacuum means comprising a second connection tube, said second portion includes a second internal passage for allowing a flow of air therethrough.
