A surgical device is disclosed which is advantageously for use in orthopaedic hand surgery where there exists the requirement to dilate a tendon sheath in order to pass a retrieved or harvested tendon through the dilated sheath. In a disclosed embodiment the device comprises an elongated body having a central bore extending from an open to a closed end, and an inflatable balloon disposed around a portion of the body portion in proximity to the closed end thereof, wherein the balloon is in fluid communication with the central bore via perforations in the outer surface of the body portion. The device also includes an aperture in the closed end for receiving a suture. Thus, the device may be progressively passed through a tendon sheath with the balloon inflated to dilate the sheath, and a tendon portion secured to the aperture in the closed end with a suture so that the tendon portion can be pulled through the dilated sheath by the device.
