Systems and methods of using a braided implant

Abstract

The disclosure relates to a braided implant, which is configured as a flow diverter for treating an aneurysm. The implant can include a braided mesh configured to maintain a substantially consistent target porosity over up to a 1 mm vessel diameter range over a predetermined length in a tapered vessel.

Description

technical field [0001] The present disclosure relates to implants within blood vessels of the body, and more particularly, to flow diverters, stents, and related methods including braided implants formed from strands of material. Background technique [0002] Vascular diseases and defects such as aneurysms and other arteriovenous malformations are particularly difficult to treat when they are located near critical tissues or where the malformation is not readily accessible. These two difficulties are especially true for intracranial aneurysms. Surgical treatment of intracranial vasculature defects is challenging and often dangerous due to the sensitivity and limited access of the brain tissue surrounding intracranial vessels. [0003] Typically, a delivery catheter is first used to guide the stent-like revascularization device under the aneurysm to be treated. One commercially available reconstitution product is CERENOVOUS as described above Vascular reconstruction devic...

Problems solved by technology

[0006] Furthermore, the weak and non-linear nature of the neurovasculature limits the applicability of such stents in surgery, for example, in the repair of neurovascular defects

Additionally, known delivery methods are less useful in vaso-occlusive surgery, especially when it is necessary to treat tiny blood vessels such as those found in the brain
