The present invention relates to inhibiting or preventing infection and protecting against patency complications after a blood catheter has been inserted in a patient comprising administering to the device a pharmaceutically effective amount of a composition comprising: (A) at least one taurinamide derivative, (B) at least one compound selected from the group consisting of biologically acceptable acids and biologically acceptable salts thereof; and (C) heparin at a low concentration.

Methods have been discovered that make it possible to continuously extrude tubes of P4HB and copolymers thereof. These methods allow tubes of P4HB and copolymers thereof to be produced without radial deformation of the tubes despite the slow crystallization of the polymer and copolymers. The methods can produce tubes of P4HB and copolymers thereof with tightly defined outside and inside diameters which are required for medical application. These tubes are produced by radial expansion at temperatures above the melting temperature of P4HB and copolymers thereof, and using low tube cooling temperatures and prolonged cooling times. The tubes made from P4HB and copolymers thereof are flexible, and can be prepared with high elongation to break values.

A holding device for a breathing tube for use in lung function diagnostics is disclosed. This holding device consists of a material that is transparent for light having a wavelength in a first wavelength range but nontransparent for light having a wavelength in a second wavelength range. In other aspects, a lung function diagnostics device comprising such a holding device and a method for reading out a coding on a surface of a breathing tube for use in lung function diagnostics are disclosed.

The purpose of the present invention is to provide a viscoelastic composition having excellent operability, which is suitable for use in securing the field of view of an endoscope when opaque dark-colored liquid accumulates inside a canal and obstructs the field of view of the endoscope, the viscoelastic composition securing the field of view by pushing the liquid aside, and to provide a method for securing the field of view of an endoscope using the viscoelastic composition. The viscoelastic composition for securing the field of view of an endoscope comprises a substance having viscoelastic properties and water, preferably has a hardness of 550 N/m.sup.2 or less, a viscosity (25? C.) of 200 to 2,000 mPa.Math.s, and a loss tangent of 0.6 or less, and more preferably has an electrical conductivity of 250 ?S/cm or less. The method for securing the field of view of an endoscope comprises feeding the viscoelastic composition from a proximal part of the endoscope, through a channel, into a distal part of the endoscope.

An extension tube for a urinary catheter comprises a tubular body with an inlet opening, an outlet opening and an internal lumen extending between the inlet opening and the opening. The tubular body comprising at least a first layer, which first layer includes natural and/or regenerated cellulose fibers, and preferably to a large extent, such as at least 40 wt %. The tubular body is further arranged to be compressible into a compacted, preferably generally flat, storage state, and to be expandable into an expanded, tubular use state.

The disclosure concerns various medical devices implemented to provide a nitric oxide rich environment for anti-microbial or anti-thrombogenic benefits. The medical device generally includes a nitric oxide donor material that is contained within a sealed cavity, and a transport medium that defines and captivates the entirety of the cavity, wherein the transport medium is permeable to both water and nitric oxide. As the nitric oxide donor material becomes saturated with water from the surrounding tissue or fluids, nitric oxide is chemically released, and the resulting nitric oxide is communicated through the transport medium to a treatment site for anti-microbial and anti-thrombogenic benefits.

The present disclosure relates to chitin derivatives of Formula (I), its isomers, prodrugs and pharmaceutically acceptable salts thereof. The present disclosure further relates to a process of preparing the chitin derivatives, its isomers, prodrugs and pharmaceutically acceptable salts thereof.

The compounds of the present disclosure are useful in antimicrobial coatings. The present disclosure further relates to an antibacterial polymeric nanocomposite and a process for preparing the antibacterial polymeric nanocomposites.

A water disintegratable catheter having a barrier layer disposed on an outer surface and/or inner surface of the catheter wherein the barrier layer comprises a hydrophobic component.

A heart valve implant comprising a supporting stent, a heart valve element, and a skirt, The skirt includes or is formed of at least one molded body, wherein the molded body is made of dried treated bacterial cellulose that has a swelling capacity that is greater than untreated bacterial cellulose of the same type.
