A device for inserting a medicament within a body cavity of a mammal, the device including a cartridge for containing the medicament, the cartridge including a housing, a retractable chamber disposed within the housing and having a lumen sized to contain the medicament, a stationary member disposed within the lumen and having a sized to provide a sliding fit within the lumen to provide for retraction of the retractable chamber about the stationary member upon actuation of the device, and means for retracting the retractable chamber while maintaining the stationary member in a stationary position. The device further includes means for activating the means for retracting the retractable chamber. The device further includes an actuator, the actuator including a handle case having a proximal portion for gripping and a distal portion including means for attaching the actuator to a cartridge.

Device for delivering medicinal implants

The invention includes an actuator for actuating a device for inserting a medicament within a body cavity of a mammal, the actuator including a handle case having a proximal portion for gripping and a distal portion including means for attaching the actuator to a cartridge for containing medicament, and means for creating a proximal to distal linear motion with respect to the handle case, wherein the cartridge includes a retractable chamber for containing the medicament disposed therein, a substantially stationary member and means for retracting the retractable chamber about the substantially stationary member while maintaining the substantially stationary member in a substantially stationary position.

Actuators for device for delivering medicinal implants

The invention includes a device for inserting a medicament within a body cavity of a mammal, the device including a cartridge for containing the medicament therein, the cartridge including a housing, a retractable chamber disposed within the housing and having a lumen, a substantially stationary member disposed within the lumen of the retractable chamber and having a uniform cross-section sized to provide a sliding fit within the lumen to provide for retraction of the retractable chamber about the substantially stationary member upon actuation of the device, and means for retracting the retractable chamber about the substantially stationary member while maintaining the substantially stationary member in a substantially stationary position upon actuation of the device; the device further including means for activating the means for retracting the retractable chamber.
