Embodiment Construction

[0031] In Figure 1 of the accompanying drawings, reference numeral 10 generally designates a sleeve guiding and reinforcing device according to a first embodiment of the invention. Device 10 includes a first, elongated, helical element 12 having spaced turns 14 . Device 10 also includes a second, elongated, helical element 16 also having spaced turns 18 . The first element 12 and the second element 16 are arranged coaxially in alignment with each other. The turns 14 of the first helical element 12 are arranged in reverse with respect to the turns 18 of the second helical element 16 so as to provide coincident intersection regions 20 and 22 .

[0032] In the embodiment shown in FIG. 1 of the drawings, the turns 14 of the helical element 12 have the same pitch as the turns 18 of the helical element 16 .

[0033] The turns 14, 18 of the helical elements 12, 16 coincide at regions 20 and 22, respectively. The regions 20 are arranged along an imaginary line extending longitudina...

Abstract

A sleeve steering and reinforcing device (10) includes a first, elongate, helical element (12) having spaced turns (14). At least one further, elongate, helical element (16) is co-axially arranged with the first helical element (12). The at least one further helical element (16) has a plurality of spaced turns (18) wound in an opposite direction to the turns (14) of the first helical element (12) such that the turns (14, 18) of the elements (12, 16) coincide at predetermined zones (20, 22), the zones (20, 22) being arranged along lines extending parallel to a longitudinal axis of the elements.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 60 / 692,848, filed June 20, 2005, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to sleeve guidance and reinforcement. In particular, the invention relates to a sleeve guiding and strengthening device and to a sleeve comprising such a device. Background technique [0004] When using a catheter, the catheter is inserted into the patient's body via an introducer. An introducer or catheter is inserted into the vascular system of the patient's body and guided to a desired location on the patient's body. In this position, the distal portion of the catheter is pushed out of the introducer to achieve the desired therapeutic effect, which may be diagnostic or therapeutic, which is performed by the clinician using the catheter. [0005] In order for the clinician to guide the introducer...
