Abstract: Provided herein are implants and methods for producing implants. In at least one embodiment, the implants include sheet-based, triply periodic, minimal surface (TPMS) portions. According to one embodiment, the TPMS portions include a gyroid architecture that provides for improved osseointegration and mechanical performance over previous implants due to novel ratios of porosity to compressive strength, among other features. In one or more embodiments, the gyroid architecture is organized into unit cells that demonstrate anisotropic mechanical performance along an insertion direction. In various embodiments, the present methods include novel selective laser melting (SLM) techniques for forming the TPMS portions of implants in a manner that reduces defect formation, thereby improving compressive performance and other implant properties.

Abstract: Embodiments relate to the use of auxetic geometries to construct the pores of membranes. Auxetic geometries expand in the transverse direction when stretched along the longitudinal direction. This behavior is counterintuitive as most materials contract in the transverse direction when stretched longitudinally. A mesh with pores that are auxetic has the potential to overcome the primary limitation of most prolapse meshes—pore collapse with tensile loading.

Abstract: Various examples are provided related to a cardiac valve repair device. In one example, the device includes an outer structure with outer blocks, and inner blocks. Each outer block can include an outer magnet pack disposed within in outer block void, at least one tension wire channel extending through the outer block between a first end and a second end and along the outer block void, a connection point on each of the first end and the second end, and attachment openings on each of a first side and a second side extending between the first end and the second end. The outer structure can also include tension wires extending through corresponding tension wire channels and connectors that can couple the outer blocks. Each inner block includes an inner magnet pack disposed within an inner block void and attachment openings that correspond to the attachment openings of the outer blocks.

Abstract: Intravascular membrane oxygenator catheter systems and methods are disclosed, along with methods of making and using the same. A catheter system includes a catheter shaft having a wall that extends from a proximal end to a distal end along a longitudinal axis to define a lumen, a plurality of hollow fiber membrane loops each having a proximal portion positioned within the lumen of the catheter shaft and a distal portion extending beyond the lumen of the catheter shaft, the hollow fiber membrane loops are nonporous with solid walls; a pneumatic source in pneumatic communication with the hollow fiber membrane loops. The pneumatic source provides a gas containing oxygen at a pressure sufficient to cause a diffusive flux of the gas containing oxygen from an interior of the hollow fiber membrane loops to a fluid exterior to the hollow fiber membrane loops in a region of interest of a subject.

Abstract: An orthopedic implant device has a bone-replacement contour that replicates a healthy bone surface contour. An exterior surface of the device has elution pores. Interior surfaces of the device define a reservoir that is spaced inward from the exterior surface. The reservoir stores a therapeutic agent delivery medium impregnated with a therapeutic agent. The interior surfaces further define elution channels communicating the reservoir with the elution pores to convey a therapeutic agent from the reservoir to the exterior surface. A solid therapeutic agent delivery medium is stored in the reservoir, and is biodegradable under the influence of synovial fluid.
