A dedicated collection of manual invasive devices intended to provide percutaneous vascular access to enable the introduction, and safe retrieval, of a thrombectomy wire-net (not included) during a thrombectomy procedure. It includes a non-steerable sheath typically with an expanding distal funnel to facilitate wire-net retrieval, an obturator/dilator, a haemostatic valve to control blood loss, and a side port. It is typically also designed to allow removal of residual clotted blood, trapped in the sheath funnel upon retrieval, through manual suction (aspiration). This is a single-use device.
