A three-dimensional printed swab may include a shaft defining a longitudinal axis of the swab, and a tip portion integrally formed with the shaft. The tip portion may include a plurality of protrusions each extending outward from the shaft and transverse to the longitudinal axis. A method for fabricating a three-dimensional printed swab may include receiving a digital three-dimensional model corresponding to the swab, and integrally forming, via three-dimensional printing and based at least in part on the digital three-dimensional model, a shaft and a tip portion of the swab. The shaft may define a longitudinal axis of the swab. The tip portion may include a plurality of protrusions each extending outward from the shaft and transverse to the longitudinal axis.

Three-dimensional printed swabs for diagnostic testing

Disclosed herein is a 3D printed heart model with simulated cardiac stroke volumes. It involves an inner membrane conforming to the shape of the inner lining of the ventricle. This results in the creation of a compression pouch with a potential space (compression sac) bordered by the inner surface of the simulated ventricle and the outer surface of the inner membrane. The inner membrane also defines a neo-ventricular chamber that is in contact with blood simulating fluid. A pulsatile flow pump can serve as a hydrodynamic driver for inflow and outflow into and out of the compression sac. This can exert a concentric force that compresses the inner sac and displaces the simulated blood residing in the neo ventricular cavity simulating systole. The fluid can then return back from the compression sac to the pump allowing the neo-ventricle to distend to accommodate returning simulated blood from the atrium simulating diastole.

Swab

An off-the-shelf oral splint that is operatively secured to the maxilla and mandible to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous patient. The oral splint is fabricated into a plurality of standardized sizes. These sizes are determined by imaging a population of jaws, measuring dimensions thereof, manipulating (e.g., calculating the mean) these dimensions, and generating a size that is representative of a subset of that population. This can be done for all sizes that would represent individuals in that population. The splint itself is fabricated virtually by creating 'U-shapes', splitting them horizontally into halves, creating an evacuation channel, and generating a coupling mechanism to hold the halves together. The splint can then be printed or otherwise manufactured.

Reduction splint for edentulous patients

Aspects of the present invention provide implants for augmentation, stabilization, or defect reconstruction of bone tissue, comprising a scaffold portion structured to provide shape to the implant, the scaffold portion comprising one or more of the following: one or more polylactic acid isomer; one or more polyglycolic acid isomer; and/or allogenic bone material, or similar compound.

In one embodiment, a reversible anchoring device includes a base having a threaded shaft and an internal passage that extends through the base along a longitudinal direction of the base and a cap having a top surface, a bottom surface, a threaded circular opening formed in the bottom surface adapted to thread onto the threaded shaft of the base, and a suture opening that extends from the top surface of the cap to the threaded circular opening through which a suture can pass.

Reversible anchoring devices

A custom oral splint that is operatively secured to the maxilla and mandible of a subject/patient to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous subject/patient. In this difficult patient population, there are very limited options for maxillomandibular fixation, and none provide stable reduction of fractures. The novel device minimizes operative time and equipment, as well as offers the ability to transition the patient from rigid fixation to elastics postoperatively. The novel device is custom-designed for each patient's degree of bone atrophy, ensuring a high quality, and effective product.
