Abstract

A medical catheter for the transvascular deployment of a collapsible medical device such as a filter has a tubular body formed by an inner tubular core surrounded by an outer thin-walled tube which is fixed to the core. The outer thin-walled tube extends outwardly beyond a distal end of the core to form a fixed thin-walled medical device embracing pod. The filter is carried on a guidewire which is slidably engagable within a central lumen of the core and the filter can be collapsed against the guidewire for loading within the pod. With the filter thus loaded within the pod the distal end of the catheter can be manoeuvred through a patient'"'"'s vascular system to a desired deployment site where the filter is discharged from the pod allowing the filter to expand within the blood vessel for use filtering blood flowing through the blood vessel.

Claims

1. A medical catheter for the transvascular deployment of a medical device, the catheter comprising an elongate tubular body having a proximal end and a distal end, a tubular housing being formed at the distal end of the body for reception of the medical device, a deployment means for engagement with the medical device, being movable through the housing to move the medical device between a stored position within the housing and an in-use position externally of the housing, characterized in that the housing comprises a tubular thin-walled medical device embracing pod fixed at the distal end of the body, the pod extending outwardly from the distal end of the body and forming an integral extension thereof.
