Delivery System Having A Nozzle With An Adjustable Spacer And Method Of Use Thereof For Improving Line-Of-Sight During A Medical Procedure And Pressurizer For Improving Line-Of-Sight During A Medical Procedure

摘要

The present invention provides a delivery system for use with a pressurizer to deliver a flowable material such as bone cement into an anatomical site under pressure. The delivery system includes a cartridge for holding the bone cement. A nozzle is mounted to the cartridge to convey the bone cement to the anatomical site. A spacer is movable along the nozzle between a plurality of adjustment positions to provide a variable clearance distance between the cartridge and the pressurizer to maintain a line-of-sight to the pressurizer and the anatomical site. The line-of-sight is particularly beneficial when using the delivery system in minimally invasive surgical procedures. A method of delivering the bone cement and an alternative pressurizer are also provided.
