A vascular repair device includes a hydrogel substrate configured to be positioned at least partially around a target vessel, a biodegradable adhesive configured to be positioned at least partially around the hydrogel substrate, and a biodegradable mold defining a trough sized to accommodate at least a portion of the target vessel and configured to contain at least a portion of the biodegradable adhesive.

A winding system for winding up concatenated hollow fibers onto a winding core includes a winding core of a device for the mass transfer and/or heat exchange between two media and which winding core is to be inserted together with the hollow fibers wound thereon, into the housing of the device and to remain therein, and at least one coupling element, preferably two coupling elements, wherein the at least one coupling element has two axially opposing connecting regions and is temporarily connectable, by means of the first connecting region, to the winding core for conjoint rotation therewith, and is temporarily connectable, by means of the second connecting region, with a drive for conjoint rotation therewith, the drive being provided for the rotation of the winding core about a winding axis.

An extracorporeal blood treatment device with a function-monitoring system, wherein the extracorporeal blood treatment device for connection to the vascular system of a patient has an input branch and an output branch. The extracorporeal blood treatment device is equipped, in a first circuit, with at least one first pump arranged between the input branch and output branch for moving the patient's blood, and, in a second circuit filled with liquid and thermally connected to the first circuit of the extracorporeal blood treatment device via a heat exchanger, it has temperature-influencing means. The function-monitoring system has, in the second circuit, two temperature sensors which are arranged upstream (TS2.sub.auf) and downstream (TS2.sub.ab), respectively, with respect to the heat exchanger, in addition, temperature sensor TS1.sub.ab is arranged in the output branch of the first circuit, downstream from the heat exchanger. The function-monitoring system moreover comprises a computer system which is operatively connected to the aforementioned temperature sensors and the temperature-influencing means and which, after the temperature has been influenced, establishes, from the detected temperature values, corresponding thermodilution curves (TDK1.sub.ab, TDK2.sub.ab, TDK2.sub.auf) and, in order to determine an indicator of the function of the extracorporeal blood treatment device, relates the TDK2.sub.ab and the TDK.sub.1ab to each other.

The device for blood oxygenation includes a gas exchange chamber with passage openings. One side the chamber is connected in a gas-tight manner with the expansion tank feeding the gas mixture containing oxygen to the chamber, having the inlet opening of gas mixture from the feeding installation. The other side of the chamber is connected in a gas-tight manner with the gas mixture discharging tank, having the outlet opening of gas mixture. The inner part of the chamber has a membrane as a capillary bundle permeable to gas mixture particles and non-permeable to blood particles, ends of which are anchored in the passage openings. The capillary bundle is tensed with a tension force and is parallel to the longitudinal axis of the chamber and to each other, or are arranged spirally. The side wall of the chamber has at least one inlet/outlet opening.
