BRANCH POINT FLOW DIVERSION DEVICE
A flow diversion device for the treatment of intracranial aneurysms and other medical conditions is disclosed. The flow diversion device may include a generally tubular wire stent frame formed from a plurality of zig-zag shaped wire elements that are coupled together. The device further includes a base layer of graft material coupled to the wire stent frame and surrounding at least a portion thereof, the wire stent frame maintaining the base layer in an open condition. In some embodiments, the base layer may be formed of porous graft material having a plurality of slits formed in the longitudinal direction. The slits may have a different shape in a compressed configuration and an expanded configuration. The slits provide a passageway for a small blood flow to maintain the long-term patency of important small side branches, while also reducing blood flow to the aneurysm to promote occlusion and avoid potential rupture.
Stent and securely-installed artificial valve replacement device having same
A stent and a securely-installed artificial valve replacement device having the same, the stent being of a cylindrical structure; the top of the stent is provided with a fixed ear (60); the fixed ear (60) has a neck portion (601) connected to the top of the stent, and a head portion (602) engaged with the fixed head of the stent; the head portion (602) has a bending structure for improving the overall radial thickness; and the artificial valve replacement device is comprised of a stent and a prosthetic valve fixed on the stent. The stent with a bending structure overcomes the problem of easily disengaging from the fixed head of the stent, while not affecting the release of the stent.
Annuloplasty ring for receiving a replacement valve
An annuloplasty ring including elastic features that make the ring optimal for receiving a subsequent prosthetic valve via a “Valve In Ring Procedure.” The elastic features provide a squeezing force on the native valve annulus that both ensures coaptation of the native valve leaflets and also prevents paravalvular leakage around a subsequently-placed prosthetic valve.
APPARATUS FOR USE IN REPAIRING MITRAL VALVES AND METHOD OF USE THEREOF
Apparatus for repairing a heart valve and methods for implanting anchors and repairing a heart valve are provided. The apparatus comprises a body, a member attached to the body at a first end and having a plurality of positioning cords spaced laterally across the member and extending away from a second end of the member opposed to the first end, a tube suspended from the plurality of positioning cords, and an adjustment cord extending through the tube. The method comprises implanting at least one annular anchor in a mitral annulus of the heart valve, implanting a papillary anchor through each papillary muscle of the heart, delivering and positioning an apparatus for repairing a heart valve inside the heart valve using the at least one annular anchor and the papillary anchors, and adjusting the apparatus to adjust the extent of atrial displacement of the heart's mitral leaflets during ventricular contraction.
STENT STRUCTURES FOR USE WITH VALVE REPLACEMENTS
The present embodiments provide a medical device for implantation in a patient comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.
Draining biological patch
The present invention relates to an innovative biological prostheses, equipped with a drainage system, designed for all surgical applications where there is any risk of hematomas or seromas, which not only allows to minimize adverse events arising from its application, but allows also to improve the effectiveness of the functional reconstruction. The prosthesis of the present invention is a surgical prosthesis made of animal derived collagen having a peripheral outline and a drainage portion comprising a plurality of drainage holes which are located in one or more independent groups each of which has a regular body-centered polygon layout.
Multilayer luminal endoprosthesis and manufacturing method
A luminal endoprosthesis (1) at least partially delimits a prosthesis lumen (2), for implantation in an anatomical structure (3) that at least partially defines at least one cavity (4) and includes a pathological portion (13). The luminal endoprosthesis (1) includes two or more layers (5, 6, 7), at least one layer (5, 6, 7) having at least one threadlike element (8) forming an armor (9). The luminal endoprosthesis (1) includes an anchoring portion (10), for anchoring to an anatomical portion (11) of the walls of the cavity (4) of the anatomical structure (3). A working portion (12) faces the pathological portion (13) of the anatomical structure (3). The two or more layers (5, 6, 7) are separated from each other at least in the working portion (12) of the luminal endoprosthesis (1), avoiding connecting elements between one layer (5, 6, 7) and at least one adjacent layer.
Annuloplasty device
An annuloplasty device is provided comprising first and second support rings having a coiled configuration in which the first and second support rings are arranged as a coil around a central axis, the first and second support rings are configured to be arranged on opposite sides of native heart valve leaflets of a heart valve, the first and/or second support ring comprises a plurality of sides forming a non-circular cross-section of the first and/or second support ring, wherein the cross-section varies along a longitudinal direction of the first and/or second support ring.
MEDICAL DEVICES FOR USE ALONG THE BILIARY AND/OR PANCREATIC TRACT
Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.
Tendon repair implant and method of arthroscopic implantation
A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic means approach that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.
