Embodiment Construction

[0030] definition

[0031] The term "elongated medical device (EMD)" refers to, but is not limited to, catheters (eg, guide catheters, microcatheters, balloon / stent catheters), wire-based devices (eg, guidewires, embolic coils, stent retrievers, etc. ), and medical devices including any combination of these. Wire-based EMDs include, but are not limited to, guide wires, microwires, proximal pushers for embolic coils, stent retrievers, self-deploying stents, and flow diverters. Typically, wire-based EMDs do not have a hub or handle at their proximal end. In one embodiment, the EMD is a catheter having a hub at the proximal end of the catheter and a flexible shaft extending from the hub toward the distal end of the catheter, wherein the shaft is more flexible than the hub. In one embodiment, the catheter includes an intermediate portion that transitions between the hub and the shaft, the intermediate portion having an intermediate flexibility that is less rigid than the hub and...

Abstract

The invention relates to a torquer for an elongate medical device. A torquer for an elongate medical device includes a body having a cavity defining a passageway. The first jaw is movable within the cavity. The first jaw includes a shim having compliant properties. A biasing member separate from the first jaw biases the first jaw relative to the body. An actuator movable relative to the body moves the first jaw to clamp and / or loosen the elongate medical device within the passageway with the first shim.

Description

Background technique [0001] Catheters and other elongated medical devices (EMDs) can be used in minimally invasive medical procedures to diagnose and treat a variety of vascular diseases, including neurovascular intervention (NVI) (also known as neurointerventional procedures), percutaneous coronary intervention (PCI) ) and peripheral vascular intervention (PVI). These procedures typically involve guiding a guidewire through the vasculature and advancing a catheter through the guidewire to deliver therapy. The catheterization procedure begins with an introducer sheath into an appropriate blood vessel, such as an artery or vein, by using standard percutaneous techniques. The sheath or guide catheter is then advanced through the introducer sheath over the diagnostic guidewire to a primary location, such as the internal carotid artery for NVI, the coronary ostium for PCI, or the superficial femoral artery for PVI. A guidewire suitable for the vasculature is then guided through ...
