  • Patent number: 10646359
    Abstract: Tubular casting processes, such as dip-coating, may be used to form substrates from polymeric solutions which may be used to fabricate implantable devices such as stents. The polymeric substrates may have multiple layers which retain the inherent properties of their starting materials and which are sufficiently ductile to prevent brittle fracture. Parameters such as the number of times the mandrel is immersed, the duration of time of each immersion within the solution, as well as the delay time between each immersion or the drying or curing time between dips and withdrawal rates of the mandrel from the solution may each be controlled to result in the desired mechanical characteristics. Additional post-processing may also be utilized to further increase strength of the substrate or to alter its shape.

  • Patent number: 10639233
    Abstract: The treatment of various sensitive organs with low energy acoustic shockwaves has been proposed. However, the prior art is lacking in guidance as to what constitutes an efficacious minimum dosage or a safe maximum dosage for various target organs and tissues. Through extensive experimentation with cultured cells, live animals, and animal disease models, the inventors of the present disclosure have determined safe and efficacious shockwave energetic dosage ranges for vital and sensitive organs, including the brain, pancreas, kidneys, liver, and spleen, as well as for skin and subcutaneous tissues, peripheral nerves, and skeletal muscles.

  • Patent number: 10639026
    Abstract: Methods and systems are provided for securing tissue to bone. A surgical system can include a driver having a proximal handle and a driver shaft extending therefrom, a distal awl shaft, a proximal awl shaft separate from the distal awl shaft and movable with respect to the distal awl shaft, a suture anchor, and a dilator feature distal to the suture anchor. The distal and proximal awl shafts are receivable in at least part of a lumen of the driver. In a bone forming configuration of the system, in which the distal awl shaft is driven into bone, a distal end of the proximal awl shaft abuts a proximal end of the distal awl shaft. The proximal awl shaft can be moved proximally, such as by activating an awl handle coupled thereto, with respect to the distal awl shaft to move the system in a suture anchor insertion configuration.
