Abstract
A voice prosthesis insertion assembly is described including a voice prosthesis device and a placement tool for positioning the device in a fistula connecting a trachea and anesophagus of a laryngectomized patient. The voice prosthesis device has an attachment means formed thereon and the placement tool has an attachment means molded integrally and homogeneously thereon for detachably interconnecting the device with the tool. As a result of this construction, a positive interconnection of the voice prosthesis device and the placement tool is maintained during positioning of the device in the fistula and such interconnection may be maintained until detachment is desired.
