Abstract: A device for dispensing a fluid product includes a reservoir configured to contain a fluid product and a spray orifice associated with the reservoir. The reservoir may include at least one actuating wall having a predetermined threshold resistance to deformation. The actuating wall may be configured to deform in response to pressure exerted on the actuating wall so as to cause the product to be sprayed out from the orifice. When pressure exerted on the actuating wall is less than a threshold pressure Ps sufficient to overcome the predetermined threshold resistance to deformation of the actuating wall, substantially no portion of the product is sprayed from the spray orifice. At least upon a first use of the device, continuous exerting of the threshold pressure Ps on the actuating wall causes spraying of the product from the spray orifice for a spray duration that is capable of being altered.

Abstract: A spacing apparatus for use with radiation therapy devices, and in particular, for use with a brachytherapy device. The spacing apparatus is useful in that the instrument is effective to limit the amount of radiation that comes into contact with the sensitive tissue proximate to the extraction site, and thereby protect sensitive tissue from overheating or hotspots, and/or protect against radiation exposure outside of the patient's body which may affect healthcare providers or others who might come close to the patient. In particular, the spacing apparatus is effective to control the proximity of a brachytherapy device to the outer surface of the sensitive tissue proximate to a surgical extraction site.
