20100114152 | Minimally-Invasive Method and Device for Permanently Compressing Tissues within the Body - The present invention is method for permanently compressing tissues in the body. The method employs a compression device made of a spring and a flexible sheet that cooperate to form a compressive envelope around the desired tissue. The spring is preferably Z-shaped or a coil. The sheet is made of a flexible material and the material is preferably elastic. The sheet is preferably a biocompatible elastic material, such as a mesh made of stainless steel or a woven or non-woven elastomer. The method is minimally invasive because it deploys the compression device through the patient's skin directly to the tissue, as opposed to through catheterization or open invasive surgery, such as open-heart surgery. The preferred use is for compressing the left atrial appendage to prevent clots from forming and circulating, thereby preventing strokes. The device is deployed by making an incision in a patient's chest, inserting the compression device through the incision into the pericardium without piercing the heart, and deploying it around the entire appendage. The device remains in place by its own compressive nature: either the spring, the sheet, or both components compress the appendage and cause the device to stay in place due to friction. Preferably the entire compression device is left in place, but the spring or the sheet may be removed, leaving the remaining component to compress the appendage. | 05-06-2010 |

The delivery system can include an elongate carrier member and an engagement component that can releasably engage the expandable device. The elongate carrier member can have a distal portion, a central axis, and a first notch in the distal portion. The engagement component can be positioned within the first notch. Further, the expandable frame can be coupled to the distal portion of the carrier member and have a first terminal end section. When coupled to the carrier member, the first terminal and section can (i) pass from a first end of the first notch through a space between the central axis and the engagement component and (ii) terminate outside of the first notch, beyond a second end of the first notch. | 01-28-2016 |
20160022445 | Occlusive Device - An aneurysm embolization device can include a body having a single, continuous piece of material that is shape set into a plurality of distinct structural components. For example, the device can have an expandable component and an atraumatic tip portion extending therefrom. Further, the tip portion can be configured to enable the device to be implanted within the aneurysm while tending to mitigate risk of puncturing the aneurysm dome or otherwise assist in framing the aneurysm in advance of placement of additional embolic material. | 01-28-2016 |
20160030049 | REMOVABLE LUNG REDUCTION DEVICES, SYSTEMS, AND METHODS - An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and recollapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by recollapsing the device and pulling the device proximally through a catheter. | 02-04-2016 |
20160051803 | Partial Circumferential Stent With Non-Radial Apposition - A medical device for sealing and repairing defects in a body lumen wall includes a wire frame and a partially-circumferential stent body. In some embodiments, the endolumenal sealing devices provided herein are well-suited for use in the GI tract including the colon. That is the case because the partially-circumferential sealing devices are configured to be compliant with the peristaltic movements of the GI tract. This feature can enable the sealing devices to resiliently remain located in a desired position within the GI tract, such that the defect in the lumen wall is sealed by the presence of the sealing device. | 02-25-2016 |
20160051804 | Partial Circumferential Stent With Non-Radial Apposition - A medical device for sealing and repairing defects in a body lumen wall includes a wire frame and a partially-circumferential stent body.

20160058989 | DEVICES AND METHODS FOR CONTROL OF BLOOD PRESSURE - Apparatus and methods are described including an implantable device shaped to define (a) at least two artery-contact regions, the artery-contact regions comprising struts that are configured to stretch an arterial wall by applying pressure to the arterial wall, and (b) at least two crimping regions that comprise locking mechanisms configured to prevent the crimping regions from becoming crimped due to pressure from the wall of the artery on the artery-contact regions. The crimping regions are configured to be crimped during insertion of the device, via a catheter, by the locking mechanisms being unlocked during insertion of the device. Other embodiments are also described. | 03-03-2016 |
20160074025 | INTRALUMINAL OCCLUSION DEVICES AND METHODS OF BLOCKING THE ENTRY OF FLUID INTO BODILY PASSAGES - An intraluminal occlusion device includes a frame and an attached covering. The frame includes longitudinal struts having concave and convex portions. The intraluminal occlusion devices can be implanted at an opening to a body vessel, such as a blind passage, to block the entry of fluid into the vessel. Methods of blocking the entry of fluid into bodily passages are also described. | 03-17-2016 |
20160095602 | MEDICAL DEVICE - A medical device and treatment method for treating veins. The medical device includes: an elongated outer sheath; an inner member extending through inside of the outer sheath, the inner member protruding distally beyond the outer sheath; an expansion portion positioned between a distal portion of the outer sheath and a distal portion of the inner member, the expansion portion having a plurality of linear material portions extending along an axial direction of the inner member, the expansion portion being expandable in a radial direction of the inner member; a biasing member disposed inside the outer sheath biasing the inner member proximally relative to the outer sheath; and a fixing portion configured to fix the relative positions of the inner member and the outer sheath in a state in which the expansion portion has been expanded. The fixing portion is also configured to be released from the fixed state. | 04-07-2016 |
