Abstract: The mapping electrodes (3) are disposed on resilient elements (4) which branch out from the shaft (2) of the catheter and each of which carries a respective electrical contact element (9). The ablation electrode (7) is disposed on the end of a manoeuvrable support element (8) which can bend in a given bending plane. The same element carries an electrical contact (10) located in a fixed position relative to the bending plane. Angular orientation of the support element (8) of the ablation electrode (7) enables a position to be reached in which there is electrical connection between the contact (10) carried by the support element 8 and the respective contact (9) carried by the flexible element (4) on which the mapping electrode (3) located at the operation site is disposed. It is thus possible to position the ablation electrode (7) at this site accurately and quickly. <IMAGE>

Abstract: A DNA template consisting of multiple tandem repetitions of an oligonucleotide unit is produced by endless copying of a circular oligonucleotide comprising at least one copy of said oligonucleotide unit by means of a nucleic acid polymerase, which is capable of strand displacement and is substantially without 5'-3' exonuclease activity, in the presence of the necessary nucleoside triphosphates and, if necessary, a primer capable of binding to some portion of the oligonucleotide. This reaction can be used in a process for the amplification of a particular DNA sequence wherein said DNA sequence is either circularized or inserted into a circular oligonucleotide, and the resulting circular DNA is used as a template for an endless copying process.

Abstract: The contrast determination apparatus includes illuminating light sources (12) and an image sensor (26) i.e. a 2-D CCD for capturing a two-dimensional image of e.g. a marked wire (32) on a holder (34), the captured image being sampled over the mark and the background. The sensor includes an optical system (28,30) selected with regard to the character size of the marks so that the field of view of the sensor is sufficient to contain a complete character as well as a generous amount of background. An area of the captured image is designated in which the samples for contrast measurement are to be taken, and a processor (24) takes the pixel values from the image which are thresholded to categorise them as "black", or "white", thus forming a two-tone image. Aggregates or averages of the "black" and "white" pixel values are used to derive the contrast measurement according to the formula: (Imax-Imin)/Imax where Imax is the average value of the "white" pixels and Imin the average value of the "black" pixels.

Abstract: A prothesis (18, 108, 120) for transluminal implantation consists of a flexible tubular three-dimensionally braided structure of metal or polymeric monofilaments (32, 110, 126), and polymeric multifilament yarns (42). The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced apart helices, concentric on a common central axis of the prosthesis. The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide one or more layers of sheeting (40) that reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft. An alternative embodiment prosthesis (132) includes elastically and plastically deformable structural strands (140), selectively plastically deformed by cold working, then three-dimensionally braided to form the prosthesis. <IMAGE>

Abstract: A syringe comprises a barrel containing an internal cylindrical body containing a liquid and communicating with a delivery needle. The needle is covered before use by a removable sheath, and after the sheath is removed, the needle is concealed by a displaceable sleeve. In use the sleeve is pressed against the skin by applying pressure while holding the barrel. The sleeve is thereby retracted into the barrel allowing the needle to penetrate the skin. The movement of the sleeve also activates a gas generator which expels the liquid from the needle. When delivery is complete and the syringe is taken from the skin, a coil spring moves the sleeve back to the starting position again concealing the needle. The coil spring is torsionally biased before use and causes a rotational movement of the sleeve relative to the barrel when the sleeve moves into and out of the barrel. This rotational movement engages a locking mechanism which prevents further movement of the sleeve and thereby permanently conceals the needle.
