Abstract: A unitary sanitary disposable absorbent incontinence pad has an elongated absorbent member between a pervious cover topsheet and an impervious backsheet. The absorbent member includes an absorbent batt which contains a combination of cellulose fibers and thermally-bondable fibers. A melt-blown web is superimposed on the batt. A portion of each lateral side of the batt is slit and turned inwardly toward the center of the batt to form a pair of fluid-barriers or dams, creating a fluid channel therebetween. The melt-blown web lies between the dams on top of the batt. Preferably the melt-blown web includes inturned side edges which may create a second channel therebetween. The assembly of batt and web are particularly effective for moving fluid longitudinally in said pad and preventing leakage along the sides of the pad.

Abstract: A knee prosthesis comprises (i) a femoral component having a medial condyle and a lateral condyle and (ii) a tibial component. The rolling surface of the medial condyle is part-spherical and the tibial component has a complementary part-spherical depression in its upper surface to receive the medial condyle. The bearing surface of the lateral condyle includes a posterior part which has a curvature in a substantially sagittal plane about a first point on a transverse axis that passes through the center of curvature of the rolling surface of the medial condyle and an anterior part which has a curvature in the same plane about a point that lies on a second transverse axis parallel to, and anterior to, the first transverse axis. The tibial component has an arcuate groove to receive the lateral condyle and to permit, in flexion of the knee after implantation, limited anterior/posterior movement of the lateral side of the tibia relative to the femur.

Abstract: An absorbent pad for use with an ostomy appliance or similar apparatus connected to a stoma extending through the skin of a patient, is formed of a flexible laminate with a liquid-permeable inner layer facing toward the patient's skin, an intermediate layer of absorbent material, and a liquid-impermeable outer layer. The layers are sealed together, and the laminate has a central opening for fitting around the connection between the ostomy appliance flange and body portion. An adhesive layer is provided on the peripheral border of the pad for sealing to the patient's skin. The adhesive layer is applied so that it encircles the absorbent surface area of the pad. The adhesive layer cooperates with the impermeable outer layer of the laminate to surround the fluid-absorbing intermediate layers of the pad and prevent fluid and odor absorbed therein from being released. The absorbent pad is further characterized in that it can be applied and disposed of separate and apart from the ostomy appliance.

Abstract: A mammary prosthesis for augmentation mammoplasty is comprised of a shell containing an insoluble, fibrous material which when the shell is inflated with inflating fluid adjusts the feel and appearance of the inflated shell to approximate natural mammary tissue.

Abstract: A set of provisional prosthesis instrumentation including an outer shell component, a first inner component, and a second inner component different from the first inner component. The first inner component comprises a substantially hemispherical interior surface therein, while the second inner component comprises a nonhemispherical, truncated cone or a nonhemispherical, substantially cylindrical surface therein. Either the first inner component style or the second inner component style may be selectively inserted into the shell component. The first and second inner components (inserts) are releasably connectable with the shell. The first style inner component may typically be used as a provisional for a bipolar prosthesis for a hemiarthroplasty procedure, while the second style of inner component may typically be used as a unipolar endoprosthesis provisional for a hemiarthroplasty procedure. The same style of shell component is utilized for both styles of inner components.

Abstract: An assembly for handling a collection container for urine or another body fluid employs a generally rigid body with a holder end and a handle end. The holder end receives and supports the collection container in an upright position to receive the fluid. The handle end forms a structure for the user to hold the supported collection container in an outwardly extended position away from the user's hand. The handle structure also includes a cover for the container. After using the handle structure to position the container for collection of the fluid, the user can then use the cover as a lid to close the collection container. The body of the handle/holder can include a pre-weakened region along which the dual handle/cover can be separated from the holder to free the cover for use.

In a preferred embodiment the prosthesis is of a non-unitary type in which the pump means is in the scrotum.

Abstract: Wound drainage system having a wound drainage catheter with an apertured distal end and a closed reservoir system. A plug in the lumen of the distal end substantially engages the lumen. A thread connects the plug to a pulling mechanism external the closed reservoir system for pulling the thread to move the plug toward the suction end of the catheter to sterilely clear the lumen. The plug may have an aperture so that multiple plugs may be positioned in the lumen, with each plug thread passing through the aperture of each upstream plug. Each plug may be separately pulled through the lumen to clear catheter of occluded material.

Abstract: The invention relates to a process for the preparation of a resorptive bone ceramic on the basis of tricalcium phosphate which can be used as a bone replacement material. In the process, natural bone material, freed from the soft tissues, is used as the starting material. The remaining organic substances are removed from this starting material by pyrolysis. The remaining bone material, which consists virtually completely of hydroxyapatite, is subsequently treated with a phosphate carrier and then subjected to a sintering step.
