A biodegradable flow diverting device (BFDD) that will regulate blood flow into an aneurysmal sac, act as a scaffold for endothelization at the neck of an aneurysm, and degrade after successful dissolution of aneurysm and remodeling of blood vessel. This BFDD and associated fabrication method have the following features: (1) This is a non-braided FDD. The pore shapes, sizes, architectures (especially at the inlet and outlet of the pores), pore densities and porosities can be controlled for the optimum performance depending on the blood vessel and aneurysmal morphologies from patient MRI images, (2) BFDD is developed on a rotary arm with programmable variable speed and diameter in conjunction with a micromotion stage (3) Fabrication system can take any material including blended/composite biomaterials by adjusting temperature of the electro-melt extruder/needle and (4) Fabrication system is compatible with CAM (computer aided manufacturing) software and able to operate based on the adapted G-code.

A system and method for planning and simulating a surgical operation to create a patient-specific spinal implant are disclosed. The system comprises a remote server configured to receive patient-specific medical image data and generate a 3D mesh model of the patient's spine using algorithms that separate vertebral bodies, remove artifacts, and smooth surfaces. A doctor's computer receives the 3D mesh model and allows real-time manipulation of intervertebral spaces to achieve a desired spinal curvature. The server generates a spinal implant design with surface-mapped endplates matching the patient's vertebral anatomy, which is transmitted to a 3D printer for manufacturing. The method includes steps of receiving image data, generating and updating the 3D mesh model based on doctor input, generating the final implant design, and transmitting it for production. The invention enables the creation of patient-specific spinal implants with improved conformity and surgical outcomes.

A wearable wound management system integrating a flexible microfluidic assembly and real-time electrochemical sensing to autonomously sample, transport, and analyze wound exudate. A Janus membrane, formed by selective deposition of perfluoroalkyl-functionalized silica nanoparticles and O2 plasma etching on a PET film, may collect fluid via its superhydrophobic wound-facing side and deliver it to a curved, wedge-shaped microfluidic channel that enhances capillary flow. Downstream, a graded PDMS micropillar array refreshes a sensing region by unidirectional fluid movement. A drop-on-demand inkjet-printed, CO2 laser-patterned flexible sensor patch may measure nitric oxide, oxygen, hydrogen peroxide, pH, temperature, and other relevant metrics. An encapsulated wireless electronic module may transmit health data for wireless monitoring. This system, combined with machine-learning analytics, may enable continuous, in situ monitoring and predictive wound classification, supporting proactive and personalized chronic wound care.

A band wrapping device forms a length of band material into a loop for automatically applying the band to a limb (e.g., wrist) of a user. The band wrapping device may receive the length of band material from a cassette receivable in the band wrapping device and can include a band transport mechanism for transporting the band material, a sealer module for sealing the band material to itself and cutting the band material to a length, and/or a ring module for reception of the limb of the user for band application. The device and its constituent components can help reduce the contact between the individual requiring a band and those applying the band, can help reduce waste by using a more precise amount of band material sized to the limb, and can help reduce the staffing requirements in areas in which the bands are to be applied.
