Patent ID: 7861634

Claim:
A method of forming a toroidal structure comprising a plurality of closed-loop toroids interconnected together, each toroid having a body defining an interior, the method comprising: providing a first toroid of the plurality of toroids having a first proximal portion and a first distal portion; providing a second toroid of the plurality of toroids having a second proximal portion and a second distal portion; forming an interconnection between the first and the second toroid by looping the first proximal portion around the body of the second toroid and passing through the interior of the first toroid adjacent to the first distal portion to cause the first distal portion to be positioned adjacent to the second proximal portion wherein each toroid includes an intermediate portion defined between the proximal and the distal portion and forming the interconnection comprises looping the first proximal portion around the intermediate portion of the second toroid to cause the first distal portion to be positioned adjacent to the second toroid's intermediate portion; and forming a second interconnection by passing the first proximal portion through an interior of the second toroid defined by the second proximal portion and the intermediate portion to cause the first distal portion to be positioned adjacent to the second proximal portion.
