The haemostatic valve assembly () includes a housing () with a chamber () therewithin. A flexible valve element () is located in the chamber () and supported by the housing (). A resilient element (), for example of foam, is located in the chamber () and applies a constant closing force on the valve element (). The valve () can be opened by aspirating fluid held within the chamber (), for example by means of a pump or syringe, thereby to create a vacuum therein which compresses the resilient element (). Removal of the vacuum allows the resilient element () to expand again and to close the valve ().

Haemostatic valve assembly

A thrombus retrieval device () includes a flexible catheter (), a retrieval wire () fixed to the distal end () of the catheter () and which extends out of the catheter () at first and second apertures in the wall of the catheter (). A trap element () typically made of a porous fabric material, is attached to the catheter () from the distal end () across the location of the apertures. The trigger wire () can be pulled in a proximal direction, which causes the catheter () to twist so as to form a loop. The trap element (), attached to the catheter at location in which it loops, forms a net for trapping thrombi or other obstructions within a patient's lumen.

Obstruction capture and removal device

A driver assembly () for an introducer assembly () for the deployment of an implantable medical device () includes a sprung element () coupled to a yoke (). The yoke () is coupled to a gripper element (). The yoke () is coupled to a first handle unit () of the introducer (). The sprung element () is coupled to a proximal handle unit (). A brake element () acts to prevent operation of the sprung element () when no manual force is being applied to attract a sheath () and the assembly (). When manual retraction force is applied to the assembly () the gripper element () the brake element () releases a sprung element () so that the lighter can apply a force assistance to assist in the retraction of the sheath () and thereby to assist in the deployment of a medical device.
