Abstract
Disclosed is a novel device for the vacuum infusion of a porous medical implant contained therein with one or more pharmaceutical substances and a method for the device's use. The device is deformable, and capable of adjusting to the outer contour of a porous medical implant to facilitate packaging, shipping and storage of the implant contained within the device. In addition, the device is unbreakable, easily disposed of after use, maintains the implant in a sterile condition before and after infusion and minimizes the quantity of pharmaceutical substance needed for infusion. Use of the device provides for rapid and complete infusion of a variety of pharmaceutical substances into a porous implant prior to surgery.
Claims42
A device for the infusion of a liquid into a porous medical implant at reduced pressure, the device comprising:
- a deformable pouch constructed from a biocompatible material, the pouch containing the porous medical implant and having an orifice suitable for the introduction of the liquid and for connecting to a vacuum.
A device for vacuum infusion of a liquid into a porous medical implant, the device comprising:
- a deformable pouch having a volume between about 1 to about 20 cubic centimeters constructed from a biocompatible material, the pouch having:
- an orifice having an open condition suitable for receiving a porous medical implant and suitable for subsequent closure;
- an orifice having a coupling member suitable for the introduction of a liquid;
- and
- an orifice suitable for connecting to a vacuum.
A method for infusing a porous medical implant with a liquid, the method comprising:
- providing a porous medical implant sealed within a deformable pouch, the pouch constructed from a biocompatible material and having an internal and external pressure;
- contacting the implant with a liquid;
- creating a pressure differential wherein the internal pressure is less than the external pressure;
- and
- maintaining the pressure differential until a desired level of infusion has been accomplished.
