Abstract: A foldable urinary catheter is provided for draining the human bladder defining an internal flow path for urine, with a catheter tube for insertion into the urethra, the catheter tube having at least one hinge which can enable the catheter into a folded, compact storage condition and an unfolded, straight ready-for-use condition as well as to a foldable urinary catheter kit. A foldable urinary catheter and a foldable urinary catheter kit are provided which are very small and compact in a transport or storage condition and which provide a long insertable length of the catheter tube. The hinge in the catheter tube is provided in the insertable length of the catheter tube and is configured for stabilizing the ready-for-use condition. The kit includes the foldable urinary catheter and a catheter package which tightly surrounds the folded catheter.

Abstract: A method of making a ready-to-use catheter assembly and a ready-to-use catheter are provided, which avoids any degradation of the catheter during sterilization. The method comprises: placing a catheter with a hydrophilic coating and a wetting fluid in a catheter package made of low moisture transmission material while the package is in a first condition wherein an insertable length of the hydrophilic coating of the catheter is not in contact with the wetting fluid, sterilizing the catheter package with the catheter and the wetting fluid by radiation sterilization while the catheter package is kept in a condition in which the insertable length is not in contact with the wetting fluid, transferring the catheter package with the catheter and the wetting fluid into a second condition, bringing the wetting fluid into contact with at least the insertable length and activating the insertable length via gravity and/or via inertia.

Abstract: A tracheostomy tube with a tracheostomy cannula is provided at least in areas with helical reinforcement and with at least one phonation opening disposed in the tracheostomy cannula. The pitch of the helical reinforcement in the area of the at least one phonation opening is increased such that the at least one phonation opening is fitted between two turns of the helical reinforcement. An improved tracheostomy tube with high stability is provided.

Abstract: A tracheal tube for the endotracheal or tracheostomatic respiration of patients by using a breathing tube, which is at least partially insertable into the trachea, comprises a trachea sealing cuff, which is arranged at the part insertable into the trachea around the breathing tube, and comprising a temperature sensor. The cuff comprises an outer balloon and an inner balloon between which the temperature sensor is arranged.

Abstract: The present invention provides a tracheal or tracheostomy tubular arrangement 1 having an outer tube 2 and an inner cannula 3, which can be inserted into the outer tube 2 and pulled out of the same, wherein the inner cannula 3 has at least one plastic layer 21 forming at least the inner surface 31 of the same, and a support structure supporting the plastic layer 21. For this purpose, the support structure is configured by a tubular interlacing 20 made of threads and/or fibers.

Abstract: In an artificial endosphincter (1) for the urethra, comprising a retaining part (2) and a valve (10) which can be manually actuated by pressure from the outside, the retaining part (2) is formed as self-expanding stent. This permits gentle, simple and safe positioning as well as reliable and simple handling of the artificial endosphincter (1).

Abstract: In a resuscitation tube (1) comprising a tube wall for alternative artificial endotracheal or esophageal obturator respiration, with a first lumen (2) and a second lumen (3) extending substantially parallel thereto, wherein a first inflatable balloon (5) surrounding the tube wall is disposed in the region of the end of the resuscitation tube (1) facing the body, and a second inflatable balloon (8) surrounding the tube wall (22) is disposed at a separation from the first inflatable balloon (5), an axial opening (10) of the first lumen (2) is disposed directly at the end of the second balloon (8) facing the body, and the resuscitation tube (1) is formed with one lumen in the region of the first balloon (5). This permits insertion of intubation aids via the first lumen (2) such that the resuscitation tube can be used with versatility.

Abstract: A tracheostomy dilator comprises a rod which is penetrated by an inner lumen. Both ends of the inner lumen are open, at the end facing the patient and at the end of the tracheostomy dilator facing away from the patient. The end facing the patient is provided with a thread. The tracheostomy dilator is used as screw dilator and can widen the tissue in one single dilation process such that a further tracheostomy cannula can be inserted into the trachea.

Abstract: In a laryngeal tube for use in microsurgery in the region of the larynx, with simultaneous ventilation and anaesthesia, which, at its introduction end, is provided with a tube bearing an inflatable cuff, and which is also provided with an inflation channel terminating in the inside of the cuff, and also a ventilation channel terminating within the lumen of the tube, provision is made for the inflation channel (6) and the ventilation channel (7) to be connected together and stiffened.

Abstract: In a tube for the enteral introduction or aspiration of gases or liquids, in particular for the enteral alimentation of patients, a weighting means is affixed in the introduction end section, the said weighting means being formed of a capsule (8) which is insoluble in the stomach, but soluble in the region of the intestine. In this manner, the tubing forming the tube can be very thin.

Abstract: The invention relates to a method for the production of a medical instrument, in particular a tube or catheter, with a balloon made of an elastomeric and/or thermoplastic material, comprising the steps of providing an inflation line for the balloon on or in one hose section and applying thereafter the cuff-shaped balloon with its two ends closely fitting and overlapping one outlet of the said inflation line. To render the production economical, a coat (3) of a parting compound is applied to the hose section (1) in the area where the balloon (10) is to be formed, whereafter the hose is sheathed by extrusion with a sheathing coat (5) of a thermoplastic or elastomeric material.
