Title:
非外傷性カップリングおよびそれを使用するカテーテル
Document Type and Number:
Japanese Patent JP6674548
Kind Code:
B2
Abstract:
A catheter includes a proximal shaft and a distal shaft having differing diameters; often, the distal shaft will have a smaller diameter than the proximal shaft. A coupling joins the distal shaft to the proximal shaft. For example, a proximal portion of the distal shaft can be inserted into the coupling through its distal end, while the proximal portion of the coupling can be inserted into the proximal shaft through its distal end. To provide an atraumatic transition from the distal shaft to the proximal shaft, coupling can taper towards its distal end, for example by using a dome- or frustoconical-shape for the distal portion of the coupling. The exterior of the coupling can be ribbed to facilitate bonding to the proximal shaft. The distal shaft can be formed into at least a partial loop having a fixed or variable radius of curvature.
