AI Technical Summary

Benefits of technology

The securement device effectively compensates for recoil crimping, ensuring a stable stent position on the catheter, reducing the risk of dislocation and trauma to vessel walls, and facilitating precise deployment of the stent.

Problems solved by technology

During delivery, the stent can thus tend to slip and dislocate from its desired position on the catheter or even become separate from the catheter, requiring further intervention by the physician.

Embodiment Construction

[0063]The present invention relates to stent securement devices, most notably positioned between the balloon and the inner shaft of the catheter. Individual elements of the below disclosed embodiments are generally interchangeable if desired. Referring to FIGS. 1-4 an angioplasty and stent delivery catheter system generally indicated at 10 includes a balloon catheter 12 having a balloon 14 on a distal end portion generally indicated at 16. FIG. 1 shows a proximal portion of the catheter at 12a and a distal portion 12b in enlarged view. FIGS. 2 and 3 show the distal end portion 16 in an even more enlarged view. The illustrative catheter 12 is of the type known as a rapid exchange or single operator catheter. However, other types of catheters may be used, such as over the wire and fixed wire types. The balloon 14 is fixed to the catheter 12 by standard means. The balloon is shown in its contracted state in. A stent 18 is fixed about the balloon by crimping thereto. The stent has a lar...

Abstract

A system / assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.
