  • Patent number: 11160657
    Abstract: An exemplary implantable prosthetic device has a coaption element and at least one anchor. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaption element can have a structure that is impervious to blood and that allows the native leaflets to close around the coaption element during ventricular systole to block blood from flowing from the left or right ventricle back into the left or right atrium, respectively. The coaption element can be connected to leaflets of the native valve by the anchor.

  • Patent number: 10932899
    Abstract: The present disclosure is directed to Myointegration, the improvement of breast implant apparatus, system and methods for a design that extends the breast implant centrifugally, or in which a separate device is utilized in combination with a breast implant, that has one or more straps originating from the breast implant extension or from the separate device. The one or more straps are looped through the pectoralis major muscle then back into the implant extension or the separate device repeatedly. The straps are eventually attached in some manner to themselves, to the implant extension, or to the separate device. Since the pectoralis major muscle contains neuromuscular spindles that sense length, velocity and acceleration, when the user changes position from supine to vertical, the gravitational force generated by the mass of the breast implant pulls on the strap or straps, which pulls the muscle and stimulates the neuromuscular spindles, thereby generating lift of the implanted breast insert.

  • Patent number: 10736991
    Abstract: Provided are methods for preparing non-gelling, solubilized extracellular matrix (ECM) materials useful as cell growth substrates. Also provided are compositions prepared according to the methods as well as uses for the compositions. In one embodiment a device, such as a prosthesis, is provided which comprises an inorganic matrix into which the non-gelling, solubilized ECM composition is dispersed to facilitate in-growth of cells into the ECM and thus adaptation and/or attachment of the device to a patient. In another embodiment, the composition is delivered intraarticularly, intrathecally, intraoccularly, intracranially, and into pleural space.

  • Patent number: 10695093
    Abstract: A novel posterolateral inter-muscular approach has been developed to access the cervical spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises: i) an anterior superior border of the trapezius muscle; ii) an anterior inferior border of the splenius capitis muscle, and iii) a posterior superior border of the levator scapulae muscle. Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

  • Patent number: 10588648
    Abstract: A clot retrieval device 1 for removing occlusive clot from a blood vessel, the device comprises an inner elongate body 3 having a collapsed delivery configuration and an expanded deployed configuration and an outer elongate body 2 at least partially overlying the inner elongate body 2. The outer elongate body 2 is expandable to a radial extent which is greater than the radial extent of the inner body 3 in the deployed configuration to define a clot reception space 11. The outer elongate body 2 comprises a distal end portion 24,49 and the inner elongate body 3 comprises a main body portion 10 and a distal portion which extends in the deployed configuration towards the outer elongate body 2 to a greater extent than the main body portion. The distal portion 10 of the inner elongate member 3 and the distal end portion 24,49 of the outer elongate body 2 together define a three dimensional protective structure to substantially prevent distal egress of clot or clot fragments from the device.

  • Patent number: 10555734
    Abstract: Systems and methods for releasably coupling an adjunct material to an end effector for a surgical instrument are provided. The adjunct can be configured to be releasably retained on a jaw, such as a cartridge or anvil, using a contractible attachment feature configured to be transitioned from an original, non-contracted configuration to a contracted configuration under application of heat. The attachment feature, such as one or more strands of a shrinkable polymer, can be engaged with the adjunct, and contraction of the attachment feature is effective to couple the adjunct with retaining members formed on the jaw. Another type of an adjunct has at least one portion configured to be reversibly stretched using application of a force such that, when the force is removed, the portion transitions from a stretched configuration to a contracted configuration and thereby causes the adjunct to be engaged with retaining members formed on the jaw.
