Problems solved by technology

However, whether manual or robotic, if the force required to move the tensile member and optional release mechanism is applied in the proximal direction, and the movement of the mechanism is relative to the rest of the medical device, The operator may then apply force to other parts of the medical device in the proximal or distal direction and move the medical device in an unintended manner
When the medical device is a vascular implant delivery device, such forces may axially displace the elongated shaft and coupled implant upon deployment, resulting in imprecise placement of the implant in the vascular system

Embodiment Construction

[0047] The device for pulling the tensile member is coupled to the medical device, and the device is considered part of the medical device when physically coupled to the medical device. Bearing in mind that when the device is described as being coupled to the proximal end of a medical device, reference to the "proximal end" of the medical device to which the device is physically coupled is a convenient way to recognize that a medical device Additional mechanisms may be included via intervening mounts added between the proximal end of the elongated shaft portion of the medical device and the mount by which the device for pulling the wires is physically connected to the rest of the medical device.

[0048] For embodiments of elongate medical devices, the elongate devices have one or more longitudinal axes. If a Y-connector is added to the elongated device such that a second longitudinal axis is formed, if the tensile member extends coaxially with or along the second longitudinal...

Abstract

Mechanisms for pulling a tensile member (24) a predetermined distance from a medical device (10) having an intracorporeal end and an extracorporeal end are disclosed. Such mechanisms may be safely operated using a robot, two hands, or in some embodiments, only one hand. Such mechanisms may include one or more cams, drums, or pulley- like members (34) and a lever (48), and may be physically coupled to an extracorporeal portion of the medical device.

Description

Background technique [0001] Related Patent Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 358197, filed June 24, 2010, the entire contents of which are expressly incorporated herein by reference. [0003] 1. Technical field [0004] The present invention relates to the field of medical devices, and more particularly to manually operated mechanisms for pulling a tensile member from a medical device. [0005] 2. Related devices and methods [0006] Vascular disease is the leading cause of premature death in developed countries. Treatment for vascular disease may include implantation of tissue-supporting scaffolds or prosthetic vasculature, such as grafts, stent-grafts, etc., that are delivered through the vasculature at a reduced size that is easier to navigate and reduces Potential for injury to the tortuous vasculature from the point of entry to the site of disease. These vascular implant delivery devices generally ...
