Kit for creating disposable dilators and method for the use thereof

A tray, comprising:

• a plurality of grooves, comprising a first groove, a second groove, a third groove, a fourth groove, a fifth groove, and a sixth groove,
• wherein the first groove and the second groove have a same first configuration, the third groove and the fourth groove have a same second configuration, and the fifth groove and the sixth groove have a same third configuration,
• wherein the second configuration is different from the third configuration, and
• wherein the third groove, the fourth groove, the fifth groove, and the sixth groove are spaced apart in a first direction.

A method of using a tray, the tray comprising a first groove, a second groove, a third groove, and a fourth groove, wherein the first groove and the second groove have a same first configuration, wherein the third groove and the fourth groove have a same second configuration, and wherein the first configuration and the second configuration are different, the method comprising:

• filing a first fluid into the first groove to a first depth;
• forming a first object after the first fluid in the first groove is frozen;
• filing a second fluid into the second groove to the first depth;
• forming a second object after the second fluid in the second groove is frozen;
• filling a third fluid into the third groove to a second depth;
• forming a third object after the third fluid in the third groove is frozen;
• filling a fourth fluid into the fourth groove to the second depth;
• and
• forming a fourth object after the fourth fluid in the fourth groove is frozen,
• wherein the first object and the second object have a first substantially half cylindrical configuration, and the third object and the fourth object have a second substantially half cylindrical configuration, and
• wherein the first substantially half cylindrical configuration and the second substantially half cylindrical configuration are different.
