Problems solved by technology

[0013] In addition, there is a risk that the patch (even if it is correctly positioned over a dural ostium or perforation) may migrate distally towards the interior of the dural sac, come into contact with the LCR, and travel caudally or towards the brain
In addition to preventing proper sealing of the dural injury, this may pose neurological risks

Embodiment Construction

[0058] In the following, a number of specific examples of the invention are described with reference to the accompanying drawings, without limiting character. In the drawings, the same reference numerals have been used to designate components having the same or similar functions.

[0059] exist Figure 1 to Figure 3 , a dural seal assembly 100 according to a first embodiment of the present invention is shown comprising an implant bonded to a guide wire 20 of section D1 (gauge 4 / 0, approximately 0.15-0.2 mm). Entry 10. In the case of a barbed guide wire 20, the diameter may be 0.4mm, where the size of the barb or needle-like structure is calculated.

[0060] The implant 10 has a long piece shape with rounded ends, and is provided in its center portion with a hole for attaching a guide wire 20 . In this embodiment, the dimensions of the implant 10 are, but are not limited to, a length of 3.5 mm, a width of 0.8 mm, a thickness of 0.35 mm, and a central hole diameter of 0.3 mm....

Abstract

The present invention relates to a dural sealing system (100) comprising: an implant (10) joined to a guiding wire (20); a transfer device (30) provided with a gripping portion (30a) and a hollow portion (30b), one end of the hollow portion (30b) ending in a nozzle (30c) couplable to an epidural needle (200), and the second end of said hollow portion (30b) being provided with an entry region (30d); and an introducer device (70) comprising a tube (70a) that has a hollow interior section and is provided with a first free end and a second closed end fixed to a stop (70b).

Description

technical field [0001] The invention belongs to the technical field of implants and medical instruments. [0002] More specifically, the device of the present invention relates to a system for sealing the dura mater of a patient who has previously undergone a medical procedure in an epidural region involving a puncture or perforation of the dura mater. Background technique [0003] The human spinal cord is bathed in cerebrospinal fluid (LCR), which in turn is contained in a complex called the dural sac: This meningeal sac is made up of meninges, the outermost part of which is the dura mater. The epidural space surrounds the dural sac and is the space adjacent to and outside the dura mater. It is occupied by connective tissue, epidural fat, and blood vessels. [0004] In many medical procedures, the human epidural space must be accessed through the use of needles. This is the case when, for example, local anesthetics or corticosteroids are injected at the site for chronic ...
