Abstract
A pressure applicator for applying pressure to a flowable implant material, e.g., PMMA. A pressure applicator or driver includes a pair of columns which are engageable with one another, preferably by threads to generate a driving pressure. A handle is provided for the operator to grasp and steady the device as he turns the handle to apply pressure to the implantable material within the applicator. A luer-lock or other connecting device is provided for attaching the applicator to a cannula (or a connecting conduit that in turns connects with a cannula) that will deliver the implant material to the desired site. Pressures of about 1000-3000 psi may be generated by this device.
Claims22
A method of preparing a high pressure applicator for driving the delivery of a flowable tissue implant material for use, said method comprising:
- providing an applicator having a first column having an inner wall, an outer wall, a first open end and a second substantially closed end having an orifice therethrough, and a second column drivably engageable with the first column to generate a pressure within the first column;
- loading the first column with flowable tissue implant material;
- engaging the second column with the first column to enclose the tissue implant material;
- and
- advancing the second column toward the first column to generate a pressure for driving the flowable tissue material through the orifice.
A method of preparing a high pressure applicator for driving the delivery of a flowable tissue implant material for use, said method comprising:
- providing an applicator containing at least 5 cc of tissue implant material therein;
- and
- actuating the applicator to generate an internal pressure of at least 1000 psi and to provide a substantially even driving force to force a flow of the implant material from the applicator.
