Embodiment Construction

[0055] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail in order not to obscure the present invention.

[0056] One approach to treating aneurysms is to provide an occlusion device intraluminally in the vicinity of the aneurysm to reduce the likelihood of aneurysm rupture. One such occlusive device is a coil. One type of existing delivery system for implanting an occlusive device in a patient includes a "ripple" locking device. A "wave" locking device has a series of undulations or "waves" within the sheath of the delivery system. An elongated delivery member disposed within the sheath is contacted by undulations within the sheath to help secure the de...

Abstract

Medical devices and systems for treating a vascular condition are described. One such device (10) includes a sheath (12), an elongate delivery member (29), and a lock (26). The sheath has a wall that includes an inner surface and an outer surface. The inner surface defines a lumen (14) along the sheath. An access opening (30) is in a proximal portion of the wall and is in fluid communication with the lumen. The delivery member is at least partially disposed within the lumen. The delivery member passes through the access opening. The lock is slidably disposed on an outer periphery of the wall. The lock slidably moves from a first position (22) to a second position (24) along a longitudinal axis of the sheath. The lock positioned in the first position restricts movement of the delivery member.

Description

technical field [0001] The present application relates generally to a delivery system for an implantable device in a patient, and more particularly, to a delivery system for an implantable device in a patient's vasculature. Background technique [0002] Lumens in the body can vary in size, shape and / or patency, and these changes can introduce complications or affect related bodily functions. For example, the walls of blood vessels, particularly arteries, can develop pathological dilations known as aneurysms. An aneurysm is observed as an outward bulge of the wall of an artery. This is the result of the walls of blood vessels being weakened by disease, injury, or congenital malformations. Aneurysms have thin, weak walls and are prone to rupture, often caused or exacerbated by high blood pressure. Aneurysms can be found in different parts of the body; the most common are abdominal aortic aneurysms (AAA) and brain or brain aneurysms. The mere presence of aneurysms is not al...
