Embodiment Construction

[0031] figure 1 The lumen occluding device 10 is shown after the entire device has been deployed into the fallopian tube 12, the lumen occluding device 10 comprising a narrow cylindrical circular frame structure 15 to which the anchor portion 25 is attached proximally . Fallopian tubes 14 are very narrow tube-shaped lumens through which the ovum or eggs pass into the uterus. The device can be implanted such that a portion of the anchor portion is in the uterus, such as figure 1 shown in .

[0032] figure 2 The device 10 is shown comprising two main components: a low profile circular frame in the form of a slotted tubular section 15; and an impermeable, expandable sheath 20 which Enclosed with a slotted tube frame. The slotted tube comprises four to six longitudinal members 18, thereby forming four to six slots having a generally convex or convex configuration, which in turn facilitates the frame in a twist-free position when the obturator is deployed. The case deforms...

Abstract

An occlusion device has spaced struts connected by end members and is covered with a sheath. An actuator runs through the frame defined by the struts and end members. The struts are delivered in tension and allowed to relax to flex outwardly for fixation. The struts can also be placed in a relaxed condition and then flexed with relative movement of the end members when coming closer together. The set position of the struts is locked. The actuator can be at least in part removed after the struts flex. An anchor can be placed proximally to the frame and it contains spaced elongated members connected into a tubular shape with circumferential bands that have bends for flexibility to collapse for insertion and expand when placed in the lumen.

Description

technical field [0001] The present invention relates to an internal lumen occlusive device which, when implanted in a bodily lumen (eg, artery, vein, fallopian tube), will facilitate direct occlusion of the lumen. In this way, it is possible to directly cut off the blood supply to tumors, necrotic tissue and aneurysms and help heal the affected area of ​​concern. Similarly, direct blockage of the fallopian tubes would prevent the movement of sperm, thereby preventing the egg from being fertilized, and thus would provide a means of direct female sterilization. Background technique [0002] The present invention relates to a method and device that will directly occlude a body lumen without relying on tissue growth to occlude the body lumen. Occlusion of body lumens for various medical procedures as well as for female sterilization is very common practice and is often performed all over the world, except in most cases the procedure relies on tissue growth (closing due to tissu...
