  • Patent number: 11311461
    Abstract: A gastrostomy device (100) comprises a gastrostomy tube (200) having a retainer lumen (235) extending between a proximal part and a distal part of the tube (200); and an inflatable retaining element (300) coupled to the tube (200) at the distal part. An interior space of the retaining element (300) is in fluid communication with the retainer lumen (300). The gastrostomy device (100) also comprises an indicator (410) being in fluid communication with the retainer lumen (235) at the proximal part of the tube (200). The indicator (410) is configured for indicating a pressure in the retaining element (300) continuously within a range from a pressure corresponding to an empty retaining element (300) to an optimal pressure for the inflated retaining element (300).

  • Patent number: 11052233
    Abstract: A tube for a medical container has a tube wall which consists of at least two layers. According to the invention, at least one layer contains a styrene-containing thermoplastic polymer (S-TPE), in particular a styrene-butadiene block copolymer (SBC) or a copolyester, a copolyester ether or a cyclic olefin copolyester. The at least one other layer contains ethylene-vinyl acetate copolymer (EVA), preferably with a vinyl acetate (VA) portion in the ethylene-vinyl acetate copolymer of from 10% to 30%, preferably 14% to 28%. The EVA can be mixed with a thermoplastic polybutene and/or SEBS to improve the tube properties. The tube wall can have a two-layer structure with an inner or an outer layer which contains the S-TPE, copolyester, copolyester ether or cyclic olefin copolyester, or a three-layer structure with an outer and inner layer containing the S-TPE or copolyester or copolyester ether.

  • Publication number: 20200306503
    Abstract: A probe device serves for insertion into a body of a patient. The probe device has a suction conduit between a distal suction feed port and a proximal suction attachment port for the attachment of a vacuum source. Moreover, the probe device has a feed conduit between a proximal feed attachment port, for the attachment of a feed source, and the distal suction feed port. This results in a probe device and a tube/connector assembly, which can be a component thereof, of which the versatility is improved in particular in the area of a medical application or an application in which biocompatibility is important.

  • Patent number: 7892209
    Abstract: To provide an access route which is leaktight and at the same time permits mobility and exact positioning of an instillation catheter (6), an arrangement comprising an instillation catheter (6) and a connector piece (1) for attachment to a tracheal or endotracheal tube is proposed. The connector piece (1) has a distal end (1a) for attachment to the tube, and a proximal end (1b) for attachment to a ventilation and/or suction device and comprises a branch (5) which serves for insertion of the catheter (6) and in which a valve (2) is arranged. The valve (2) is made, at least in some areas, from an elastically deformable material and can be opened by insertion of the catheter (6). The valve further comprises a proximal through-opening (21) whose inner wall has a means allowing sealing against axial flow of fluid between catheter (6) and inner wall, and, in the distal direction from the through-opening, it has a beak section (22) which, at its beak tip (23), has a normally closed slit (24).

  • Patent number: 7060050
    Abstract: A balloon-button system or a catheter for performing percutaneous enteral feeding includes a holding part, which can be placed on the abdominal wall, and a probe tube, which extends from the holding part while being connected thereto and via which the nourishment that is inserted through a connecting part situated in the holding part can be introduced into the stomach lumen. A distal end of the probe tube is turned inside out and pulled back over the probe tube and joined in a fluid tight manner to form a single-piece probe tube having an inner and an outer tube portion wherein the outer tube is expandable to form a balloon by introducing a fluid. This system is characterized in that the probe tube surrounds a protective tube, and the protective tube has a higher Shore A hardness than the probe tube.
