Abstract: The disclosed subject matter relates to a device, system and method for locating and repairing a pulmonary air leak in a patient.

Abstract: A minimally invasive device, containing a pressure channel, camera, and optical fiber imaging probe, to measure the stiffness of tissues in vivo and ex vivo is disclosed. The device is inserted into a patient and navigated to a tissue of interest, where stiffness is evaluated by applying suction and measuring the elongation or by applying compression force and measuring the compression of the tissue. Biopsies can be taken for further analysis, or tissue can be removed using an ablation laser. Small fluorescent molecules or therapeutics can also be delivered for improved visualization and targeted treatment. As such, this technology may be used to evaluate the stiffness of biomaterials as well as tissues and organs that are difficult to access, allowing for simultaneous diagnosis, treatment, and excision of diseased tissues.

Abstract: Medical devices having engineered mechanically functional cartilage from adult human mesenchymal stem cells and method for making same.

Abstract: Described are systems, methods, and devices relating to normothermic extracorporeal support of an organ, tissue, or bioengineered graft comprising cross-circulation (XC) perfusion for prolonged periods (days to weeks) via an XC perfusion circuit in connection with an extracorporeal host (e.g., animal, patient, organ transplant recipient) are disclosed. The XC perfusion circuit comprises auto-regulation of blood flow based on the trans-organ blood pressure difference between arterial and venous pressure. Recipient support enabled 36 h of normothermic perfusion that maintained healthy lungs with no significant changes in physiologic parameters and allowed for the recovery of injured lungs. Extended support enabled multiscale therapeutic interventions in all extracorporeal lungs. Lungs exceeded transplantation criteria.

Abstract: Provided are a system and method to culture human cardiac muscle tissues in a bioreactor comprising a plurality of culture wells arranged linearly between two carbon electrodes that are exposed within each well; and two horizontal parallel flexible pillars extending from each well wherein the pillars in each well are configured to suspend an engineered tissue. Also provided is method for diagnosing myocarditis in a subject by analyzing human cardiac muscle tissues cultured in the bioreactor in the presence of blood serum or antibodies from the subject.

Abstract: A method of detecting or diagnosing squamous cancers in a sample from a subject, including isolating extracellular vesicles from the sample, wherein the extracellular vesicles are cancer specific.

Abstract: Disclosed are systems and methods for culturing systemic bioengineered tumor models, including osteosarcoma cells or breast adenocarcinoma cells derived from patients. The model includes the tumor cells on host tissues such as bone, liver, lung, and heart tissue, wherein the bone, liver, lung, and heart tissue are separated by endothelial barriers. Beneath the endothelial barriers the tissues are connected via circulation containing secreted factors and cells (e.g., tumor/immune cells).

Abstract: The present invention relates to a computer-vision based autonomous steerable catheter device and methods of using the same for targeted delivery of a liquid microvolume into the interior of a lung.

Abstract: The present disclosure relates to a pneumatic microfluidic platform for high-throughput studies of cardiac hypertrophy that enables repetitive (hundreds of thousands of times) and robust (over several weeks) manipulation of cardiac ?tissues. The platform is reusable for stable and reproducible mechanical stimulation of cardiac ?tissues (each containing only 500 cells). Heterotypic and homotypic ?tissues produced in the device were pneumatically loaded in a range of regimes, with real-time on-chip analysis of tissue phenotypes. Concentrated loading of the three-dimensional cardiac tissue faithfully recapitulated the pathology of volume overload seen in native heart tissue. Sustained volume overload of ?tissues was sufficient to induce pathological cardiac remodeling associated with upregulation of the fetal gene program, in a dose-dependent manner.

Abstract: An anatomically-shaped, human bone graft may be cultivated ex vivo using a bioreactor capable of perfusing large complex porous scaffolds. Scaffolds derived from image-based modeling of a target are seeded with human mesenchymal stem cells and cultivated. A bioreactor configured to house complex three-dimensional scaffold geometries provides controlled flow for perfusion of the cells. Dense uniform cellular growth can be attained throughout the entire scaffold as a result of the medium perfusion. In an embodiment, the bioreactor has a mold into which perfusion medium is pumped under pressure and multiple ports through which the medium exits the mold.

Abstract: A bioreactor is provided that permits engineering of multiple different tissues. The bioreactor has a series of flow paths that permit application of tissue-specific media while simultaneously innervating the various different tissues with a common media. The flow paths for the various medias are designed to prevent mixing of the various media as they simultaneously innervate the tissue.
