  • Publication number: 20090143868
    Abstract: A malleable bag connected to a one-way valve can be used to provide a prosthesis with an accurate impression of a residual limb and to perfect accurate static and dynamic alignment of the prosthesis on a patient. Methods and systems allow to rapidly and accurately capture an impression of a residual limb, including soft tissue compression due to the weight of the patient.

  • Publication number: 20070296107
    Abstract: A system and method for casting molds that can be used, for example, to make prosthetic or orthodic devices or any other suitable object. The system and method uses an elastic bag containing an elastic, flexible, conformable or resilient material, such as micro polystyrene beads, to cast negative and positive molds of the object using the application of vacuum suction.

  • Patent number: 4246909
    Abstract: A disposable urethral catheter assembly includes a flexible bag in which a number of chambers are defined by barriers. In an upper chamber, a catheter is contained in a sterile environment. When the catheter is inserted through the urethra into the bladder, the fluid flows into the bag through the upper chamber and into a lower sample chamber, excess fluid being collected in the upper chamber. After catheterization, a one-piece element which provides a sealable passageway through the first barrier between the upper and lower chamber can be readily closed by manipulation through the wall of the bag and thus isolate the sample in the lower chamber. The upper chamber, its contents and the catheter are separated from the sealed lower chamber and discarded. The lower sample chamber which provides a sterile environment for its contents can then be sent to a laboratory for analysis and culture.

  • Patent number: 4204527
    Abstract: A disposable urethral catheter assembly includes a flexible bag in which are defined a number of chambers. In an upper chamber, a catheter is contained in a sterile environment. When the catheter is inserted into the urethra, the fluid flows into the bag and into a lower sample chamber, excess fluid being collected in the upper chamber. After catheter use, a cannula plug seals a first barrier between the upper and lower chamber and thus isolates the sample in the lower chamber. The upper chamber, its contents and the catheter are discarded, and the lower sample chamber and its contents are sent to a laboratory for analysis and culture.

  • Patent number: 4170996
    Abstract: A reuseable catheterization unit, including a catheter member of a predetermined diameter, a hollow flexible sleeve means connected at one end to the large diameter portion of the catheter and a hollow tubular connector means positioned at the opposite end of the sleeve means and axially spaced from the anterior end of the catheter, said connector mean adapted to sealingly connect with the large tubular end of the catheter to form a closed ring capable of sealingly retaining an antiseptic fluid within the lumen of the sleeve as well as contacting the exterior and lumen of the catheter for aseptic storage between catheterization procedures.
