Abstract

Utility Model Patent for a true and temporary endovascular distal occluder guide microcatheter which is comprised of a (flg 1) balloon guide microcatheter body 3 distal occluder 2 endowed with mandrel 5 of similar or different material and distal end with connection 4 for occlusion or extension with or without mandrel simultaneously.

Description

"EMBOCA PROTECTION SYSTEM"

The present utility model patent aims at a catheter model serving as a guide and occluder simultaneously for endovascular procedures. This catheter can serve as a distal protection system for embolization prevention during endovascular surgeries to improve efficiency and minimize existing deficiencies in all other distal protection guides and types.

Current guides of various shapes and sizes are already known.

However, the current guidelines for being free in the vascular lumen allow lesions in the vascular endothelium due to direct trauma of the own movement as the system due to instability. They do not prevent embolization, and may even be responsible for complications.

In view of all the above drawbacks and with the purpose of enabling endovascular procedures with due and necessary safety, a new guide model was developed which consists in the creation of a true and temporary distal occlusive guide microcatheter whose basic principle of action for protection against occlusal and thus stabilization of the whole system.

This type of device consists of a family of microcatheters of different sizes and materials that can be used in any type of endovascular surgery using current endovascular guides.

Initially the suggested diameters of this family are 0.0010 ", 0.0014", 0.0018 "and 0.0035" compatible with the current ones.

The endovascular occlusal distal balloon guide microcatheter will cause temporary occlusion and guide the overlying endovascular systems throughout the procedure. Its compatibility with all tabs allows its use by all existing ones.

This solves the problems of system instability and direct guide trauma in addition to the lower risk of vasospasm.

The accompanying drawing shows the distal endovascular occlusive guide microcatheter object of the present invention in which: Figure 1 shows the endovascular distal occlusal guide microcatheter in longitudinal and transverse (A-A).

As illustrated by the related figure, the deutility model of the present invention consists of a family of catheters being of similar structure differing in the profile (scale) and type of material used in the confection.

Figure 1 represents the endovascular distal occluder guide microcatheter consisting of a body 3 with a distal balloon 1 at the inner (or proximal) end provided with a light 2 enabling insufflation of the distal balloon 1. The outer (or distal) end has a connection 4 of said catheter that enables light 2 to inflate balloon 1, occlude the end and / or allow its extension 5 with or without light filling2. In this way it configures greater flexibility or tracing to the catheters that will over this during the procedure with the necessary stability. Occlusion of the treated site simultaneously prevents embolization.
