Dilator facilitating stitching of opening in e.g. casing, balloon, surface or artery, expands to cause transverse approach of opening edges

A central section (5) for thread clamping and release, provides for dilation in one direction (X-X). This tenses the stitching region of the object, causing mutual approach of edges, transverse to the dilation. Preferred features: The central thread clamping section (5) is dilated mechanically and/or electrically and/or pneumatically. Dilation is caused by extension of an edge section of the central clamp. The clamp comprises a central section (5M) and two edges (5R1, 5R2) which can be moved relative to it. Actuators (DZ1, DZ2) push or pull edge sections relative to the center. There are two clamp sections in the central clamp. They are accommodated in a tube when inactive and are spring-loaded outwardly. The tube is retracted in the active state, and they are pressed apart. The clamping sections are drawn together by an actuator. Edge sections are moved relatively, by a cam-track control device. Pneumatic or hydraulic chambers are employed as actuators. To rest on the object, e.g. an artery ...

Synergistic combination of a substance with gastric acid secretion inhibiting effect and an acid degradable antibiotic.

The invention consists of a combination of a substance that increases the intragastric ph and an acid degradable antibacterial compound. By this combined product regimen it will be possible to obtain maximal local antibacterial effect of acid degradable antibiotics, as well as enhanced bioavailability of the active antibiotic, thus resulting in higher amounts of the active compound in the gastric mucosa due to secretion of weak bases. Both pharmacological effects contribute to drastically increased antimicrobial capacity of acid degradable antibiotics to be used against local infections in the gastrointentinal tract causing gastritis and/or peptic ulcer. The invention also selects to the use of said combination and a process for the preparation thereof.
