  • Publication number: 20240238558
    Abstract: A vascular treatment device for use in a vessel includes a catheter and a microvalve occluder. The occluder includes braided elastic strands, each with a proximal portion, a central portion, and a distal portion, that are fixed to the outer surface of the catheter. The elastic strands. In an embodiment, the distal portions are attached circumferentially about an outer surface of the catheter at a location toward the distal end of the catheter, the central portions extend proximal and radially outward from the distal end, and the proximal portions of the strands are inverted back radially within the central portions are and coupled circumferentially about the outer surface of the catheter at a location proximally displaced from the distal portions. The proximal portion of the microvalve is coated in a fluid-impermeable membrane, and the distal portions of the strands are substantially uncoated.

  • Publication number: 20240100777
    Abstract: A light polymerizable composition for use in the additive manufacturing of medical devices may include a first photo-initiator and a second photo-initiator. The first photo-initiator activates to initiate curing of the composition when exposed to light of a first wavelength in an additive manufacturing device and the second photo-initiator limits the transmission of the light of the first wavelength that activates the first photo-initiator in the additive manufacturing device. The second photo-initiator is activated to further cure the composition when exposed to a light of a second wavelength different from the first wavelength by activating the second photo-initiator to produce free radicals at a higher rate when exposed to the light of the second wavelength than when exposed to the light of the first wavelength.

  • Patent number: 11865785
    Abstract: A process for additive manufacturing of a resorbable implant to be implanted into a patient includes providing a biocompatible resin including a liquid light-polymerizable material that is resorbable after polymerization and an initiator. The process further includes actuating an additive manufacturing apparatus to expose an amount of the biocompatible resin to light to at least partially cure the exposed amount of biocompatible resin to form a layer of the resorbable implant and actuating the additive manufacturing apparatus to expose at least some additional amount of biocompatible resin to light to at least partially cure the exposed additional amount of biocompatible resin to form an additional layer of the resorbable implant and to at least partially overcure previously cured layers to cause at least some interlayer binding between the previously cured layers and the additional layer.

  • Publication number: 20230380877
    Abstract: A device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress/strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient. A method of 3D printing nitinol to create a patient-specific device to facilitate the establishment of a normal stress-strain trajectory in grafted bone.
