  • Patent number: 10702384
    Abstract: A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.

  • Publication number: 20190159785
    Abstract: The present disclosure relates generally to apparatuses and methods for delivering an occlusion device to a paravalvular leak. In some embodiments, a paravalvular occlusion apparatus includes a catheter having main body including a proximal end and a distal end, a visualization element disposed in the distal end of the main body, and a working channel extending from the distal end of the main body. The catheter further includes an elongate shaft extendable from the working channel, wherein an occlusion device is coupled to the elongate shaft. In some embodiments, an occlusion device includes a leading end including a first section, and a trailing end opposite the leading end, the trailing end including a second section. The first section and the second section of the occlusion device are operable to be positioned along a perimeter of a prosthetic valve for blocking the paravalvular leak.

  • Publication number: 20190159770
    Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as an atrioventricular valve, may include an anchor delivery device including a sheath for at least partially retaining an anchor in a collapsed form. The anchor delivery device may be configured to deliver the anchor to the atrioventricular valve. The anchor and an adjacent anchor may be connectable to each other in an expanded form, to link a series of anchors implanted at least partially around the atrioventricular valve. In some embodiments, the anchors may be connectable by a connecting member, such as a pledget, or a material disposable on a bulb of the anchor. In other embodiments, a bulb of the anchor and a bulb of the adjacent anchor may be configured to be directly interlocked.

  • Patent number: 5716360
    Abstract: A patella recession instrument (10) and method provides a guide for producing an oval, tri-oval, or elliptically shaped recess on the posterior surface of the osteotomized patella for receiving a similarly shaped backing portion of a patellar implant. The apparatus includes a guide bushing (12) and a bushing positioning mechanism (14) for securing the bushing against the posterior of the osteotomized patella, with a guide opening (54) formed through the bushing covering the total area to be recessed. A reamer guide structure, which may be a separate structure (16) received in the bushing guide opening (54) or integrally formed with the bushing (12), receives one or more rotary reamer tools (18) in a plurality of reaming positions. The cutting face (80) of the rotary reamer tool (18) in each different reaming position covers a different portion of the total area to be recessed.

  • Patent number: 5271737
    Abstract: A tibial prosthetic implant includes a base or base plate with an offset tibial stem. The base includes an inferior surface adapted to abut a resected surface of a patient's tibia and forms a base for articulating surfaces adapted to articulate with the patient's femoral condyles. The longitudinal center axis of the tibial stem extends from the inferior surface of the base and is offset from a center of the base. The offset places the stem in position to extend into the central canal of the tibia so that it does not substantially interfere with the cortical bone when the inferior surface of the base substantially abuts and aligns with the resected surface of the tibia.
