Abstract: Process for the stabilization of blood plasma components in a lyophilizate, wherein in a freeze-drying process, said blood plasma components were in a solution containing at least two different pH-lowering substances causing a predetermined pH value range to be adjusted in the solution formed upon reconstitution.

Abstract: Transverse stiffening of the elastic tape is provided by means of the application of beads of a homogenous material, preferably an adhesive. Applied in liquid form, this material bonds with the surface of the elastic tape, or penetrates it, and in this manner adheres firmly. Following a curing process, the homogenous mass has the required properties and provides the elastic tape with the desired transverse stiffening.

Abstract: The inventive probe has a probe tube and a guide stylet. The probe tube has a flexible, easily deformable wall and a tip which produces an opaque shadow, with one or several conduits for the flow-through of the X-ray contrast medium. The probe tube is introduced either through the esophagus into the stomach. Once the tip has arrived there, the physician attempts to find the pylorus with the probe tip by means of X-ray control and insert the probe therein. The invention features an elastic-walled probe tube with a soft tip area, such that it substantially adapts itself to the curvature of the tip area of the guide stylet and is not capable of counteracting the curvature of the tip area or straightening it. The tip of this guide stylet is sufficiently rigid that, when inserted into the probe tube as far as the tip of the latter, it forces its own shape on the probe tip, which makes it easier for the physician to find the way into and through the pylorus with this curved tip.

Abstract: Bone harvest or bone biopsies so far are made with the use of rotating hollow drills or through axial insertion of a hollow device. Upon retraction of the instrument the problem exists that the bone core often does not detach from its basis and thus cannot be harvested with ease. Additionally, using these methods, often the histology of the bone is disturbed significantly. This problem is solved by this invention by the use of a bone harvesting device which consists of a hollow cylinder, has cutting teeth at one end and has an interior cross-section which is not round. This device can be inserted into the bone using circular oscillation, creating a bone core which has a shape deviating from a strict cylinder shape. Once the desired depth has been achieved, the bone core can be reliably sheared off its basis by rotating the instrument in an angle exceeding the angle of the oscillation.

Abstract: This invention describes a bone lengthening device, which is fully implantable and works on a cylinder and piston basis which is driven with micro-hydraulics or a internal threaded rod. Choosing a profile which is not round, torsion of the cylinder and piston assembly is avoided, and expansion can be achieved both in a linear as well as in a circular fashion. Since this device is fully implantable, common disadvantages with current methods of bone expansion can be eliminated.

Abstract: A pipe-shaped ureter splint of a resilient material which in its position of use is located in the renal pelvis with one of its ends and with the other end in the bladder, wherein on the outside of the end provided for insertion into the bladder a thin-walled, soft, collapsible hose, of one-piece construction at least in its cross-section, is closely attached and projects beyond the front face of this end of the ureter splint, the cross-section of the hose has a shape that is oval, elliptical, or approximately the shape of an elongated rectangle wherein the transitions from the long to the short sides are rounded off, and the hose functions as an anti-backflow valve.

Abstract: A catheter device having a ureter tube, an auxiliary tube, and a moveable mandrin. The upper tip of the ureter tube has an inherent curvature. The upper tip of the mandrin has an inherent curvature. The upper tip of the mandrin can project above the upper tip of the ureter tube. A hollow space inside the mandrin contains a steering wire.

Abstract: A device for the insertion of a ureter into the ureter or renal pelvis has a ureter tube with an opening of its distal tip, an auxiliary tube and a mandrin. In the insertion position, at least the ureter tube and mandrin are releasably connected. A connecting-piece at the proximal end of the mandrin makes an injection of an X-ray contrast medium into the hollow space inside the mandrin possible where it passes to an outlet opening at the distal end of the mandrin which outlet opening has an entry to the ureter. The mandrin preferably has an inherent curvature in its distal tip and a moveable steering wire can be placed into the lumen of the mandrin.

Abstract: A circularly oscillating saw, used mainly in the surgical field which, while having minimal dimensions, must have a high cutting capacity with an atraumatic cool cut, without running hot itself. The saw provides a direct connection of the saw blade with an eccentric and a suitable bearing approximately in the center between the saw blade tip and the eccentric, which provides a circularly oscillating cutting. The saw allows a cut to take place not only in parallel to the saw blade but in all directions of a plane. In addition, contamination of a wound by lubricants and bearing debris is prevented because of the excellent transport of chips and coolant. Also, the saw is to easily cleaned, sterilized and repaired while the manufacturing of this precision instrument is efficient. An internal cooling protects from the saw running-hot and ensures an optimal coolant supply. Drive-side and output-side sealing devices achieve a hermetic sealing-off of the saw mechanism.

Abstract: In order to elevate and treat diseased testes and epididymides of a recumbent man, they must, for medical treatment, be lifted above the level of the thighs by a testis support. The testis support indicated for this purpose has, in its longitudinal axis, a slight V-shaped deviation from planarity so that its wings lie on and lightly grip the two thighs of the recumbent man. A recess to receive the attachment of the scrotum is present in the V notch on one longitudinal edge. The support is composed of rigid, partially rigid or completely elastic soft material.
