Abstract: A patient stimulation device is provided comprising a plurality of stimulators for selectively applying a stimulus to a patient's body. Each of the plurality of stimulators is locatable in a different position upon a patient's body. A patient input interface is provided for receiving data representative of a perceived stimulus from the patient, and an output is provided for communicating to a patient data representative of an applied stimulus. The device comprises a controller having a training mode, the training mode comprising the controller actuating at least one of the plurality of stimulators to apply a stimulus to the patient's body, subsequently receiving data representative of a perceived stimulus from the patient input interface, and subsequently providing the output with data representative of the applied stimulus for communication to the patient, such that the data representative of the applied stimulus identifies, or allows the identification of, the applied stimulus.

Abstract: An aerosol generator 200 is positioned adjacent to a patient as an attachment to a trocar 201. The trocar has an entry port 203 for insufflation gas 208. Aerosol 207 generated by a vibrating element 205 is entrained in the insufflation gas and the mixture 209 is delivered through the trocar 201. The aerosol may contain a medicament. The trocar 201 may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolised medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolised medicament to the pneumoperitoneum regions. The surgeon can temporarily remove a camera from the trocar port to facilitate insertion and positioning of the aerosolising unit.
