244 results about "Clavicle" patented technology

The clavicle or collarbone is a long bone that serves as a strut between the shoulder blade and the sternum or breastbone. There are two clavicles, one on the left and one on the right. The clavicle is the only long bone in the body that lies horizontally. Together with the shoulder blade it makes up the shoulder girdle. It is a touchable bone and in people who have less fat in this region, the location of the bone is clearly visible, as it creates a bulge in the skin. It receives its name from the Latin: clavicula ("little key") because the bone rotates along its axis like a key when the shoulder is abducted. The clavicle is the most commonly fractured bone. It can easily be fractured due to impacts to the shoulder from the force of falling on outstretched arms or by a direct hit.

Device for treatment of acromioclavicular joint dislocations

A surgical fastener system for acromioclavicular (AC) joint dislocations, includes a first fastener having an elongate body, and an inner pair of openings centered on the long axis of the body. A closed loop stitch passes through the openings, and the length of the stitch corresponds to the depth of a passage defined between the top of a first hole bored through a patient's clavicle, and the bottom of a second hole bored through the coracoid in axial alignment with the first hole. A second fastener has an elongate body arranged to slide under a portion of the loop stitch that protrudes from the top of the hole in the clavicle, after the first fastener is set beneath the coracoid and the stitch is pulled upward through the passage. In an alternate embodiment, the second fastener also has an inner pair of openings for passing and engaging the loop stitch.

Methods and devices for treating aortic atheroma

A method for treating both sessile and mobile aortic atheroma is described. A radially expanding device, such as a stent or compliant cast, comprising a generally cylindrical member expandable between a compressed state and an enlarged state is provided. The cylindrical member has a proximal opening, a distal opening, a lumen therebetween, and at least one side opening in the wall of the generally cylindrical member. The methods comprise imaging the aorta to identify position and extent of atheroma. The stent is then advanced into the aortic arch and positioned so that the at least one side-opening is aligned with the takeoff of one or more of the right brachiocephalic artery, the left common carotid artery, or the left subclavian artery. The stent is expanded into contact with the endoluminal surface of the aorta and atheroma is trapped between the stent and the endoluminal surface of the aorta.

Devices and methods for reducing cardiac valve regurgitation

ActiveUS20130338763A1Reduce refluxAvoid blood stagnationBalloon catheterBall valvesRight atriumClavicle
The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valve—i.e., the mitral valve and the tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. Finally, there is a proximal anchoring feature to fix the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets.

Clavicle Bone Plate

A bone plate for treating clavicle fractures. The bone plate may include an elongated body having one or more curved portions that roughly conform to the surface and / or anatomical curvature of the clavicle. One or more openings may be provided for receiving an anchoring member, such as a bone screw, for fastening at least a portion of the bone plate onto the clavicle. The bone plate may provide at least one rail member extending along a portion of the body of the bone plate. The bone plate, when affixed to the clavicle, permits the rail member to rest upon the outer surface of the clavicle, thus providing an area defining a cavity formed between an outer surface of the clavicle and a bottom surface of the body of the bone plate, and thus allowing blood to circulate against and around the clavicle.

Minimally-invasive devices and methods for treatment of congestive heart failure

A method of treatment of congestive heart failure comprises the steps of introducing an aortic occlusion catheter through a patient's peripheral artery, the aortic occlusion catheter having an occluding member movable from a collapsed position to an expanded position; positioning the occluding member in the patient's ascending aorta; moving the occluding member from the collapsed shape to the expanded shape after the positioning step; introducing cardioplegic fluid into the patient's coronary blood vessels to arrest the patient's heart; maintaining circulation of oxygenated blood through the patient's arterial system; and reshaping an outer wall of the patient's heart while the heart is arrested so as to reduce the transverse dimension of the left ventricle. The ascending aorta may be occluded and cardioplegic fluid delivered by means of an occlusion balloon attached to the distal end of an elongated catheter positioned transluminally in the aorta from a femoral, subclavian, or other appropriate peripheral artery.
