BONE TREATMENT SYSTEM

摘要

To favorably discharge gas internally present in a device during filling of a bone filling material, a bone treatment system has a shaft that has a flow path which enables a bone filling material to be placed on a space of a radius to flow therethrough, and a filling balloon that communicates with the flow path in a distal portion of the shaft and that is filled with the bone filling material. Furthermore, the bone treatment system includes a gas discharge portion that causes air (gas) inside the flow path to flow in a direction toward a proximal end rather than the filling balloon, when the bone filling material is supplied to the flow path.

主权项

1. A bone treatment system comprising:
a shaft possessing a lumen which permits bone filling material to flow through the lumen of the shaft and be placed at a bone treatment site, the shaft possessing a distal portion; a balloon disposed at the distal portion of the shaft and attached to the shaft, the balloon possessing an interior in communication with the lumen in the shaft so that the bone filling material flowing through the lumen of the shaft enters the balloon to expand and fill the balloon; and a gas discharge portion that causes gas inside the lumen to flow in a direction toward a proximal end rather than the balloon when the bone filling material is introduced into and flows through the lumen of the shaft.
