Methods of making conditioned cell culture medium compositions

Novel products comprising conditioned cell culture medium compositions and methods of use are described. The conditioned cell medium compositions of the invention may be comprised of any known defined or undefined medium and may be conditioned using any eukaryotic cell type. The medium may be conditioned by stromal cells, parenchymal cells, mesenchymal stem cells, liver reserve cells, neural stem cells, pancreatic stem cells and / or embryonic stem cells. Additionally, the cells may be genetically modified. A three-dimensional tissue construct is preferred. Once the cell medium of the invention is conditioned, it may be used in any state. Physical embodiments of the conditioned medium include, but are not limited to, liquid or solid, frozen, lyophilized or dried into a powder. Additionally, the medium is formulated with a pharmaceutically acceptable carrier as a vehicle for internal administration, applied directly to a food item or product, formulated with a salve or ointment for topical applications, or, for example, made into or added to surgical glue to accelerate healing of sutures following invasive procedures. Also, the medium may be further processed to concentrate or reduce one or more factors or components contained within the medium.

Method and apparatus for performing minimally invasive surgical procedures

A system for performing minimally invasive cardiac procedures. The system includes a pair of surgical instruments that are coupled to a pair of robotic arms. The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may also have a robotically controlled endoscope which allows the surgeon to remotely view the surgical site. A cardiac procedure can be performed by making small incisions in the patient's skin and inserting the instruments and endoscope into the patient. The surgeon manipulates the handles and moves the end effectors to perform a cardiac procedure such as a coronary artery bypass graft.

Methods and apparatus for safe application of an intubation device

Intubation is a potentially dangerous invasive procedure with many plausible errors, such as over-inflation of a cuff and insertion of an intubation tube in the wrong lumen, potentially resulting in a patient's internal bleeding, suffocation, or even death. An intubation aide according to example embodiments of the present invention allows intubation of a patient, while eliminating potential injury to the patient, increasing accuracy and reliability of the placement of the intubation tube, and drastically decreasing procedural time. Within moments of insertion of the device into a patient, the medical caregiver knows, with complete certainty, the location of the intubation device without applying traditional time-consuming tasks. Embodiments also provide patient safety, if intubated for a prolonged periods, by regulating an inflation pressure of the cuff. The intubation aide can also be used for training purposes and is ideal for intubation in hospital and field settings.

Externally applied RF for pulmonary vein isolation

A resonant circuit is incorporated in a stent, which implantable in a pulmonary vein using known cardiac catheterization techniques. When an external RF field is generated at the resonant frequency of the stent, RF energy is re-radiated by the stent toward electroconductive tissue in the wall of the pulmonary vein, and produces a circumferential conduction block. The stent can be made of biodegradable materials, so that it eventually is resorbed. Following an ablation procedure, the stent may be left in situ. Repeated ablation can be performed using the inserted stent until it has been determined that the desired lesions have been formed. Furthermore, the same stent can potentially be used even years after being inserted should the treated arrhythmia reoccur or a new arrhythmia develop, thereby possibly obviating the need for an invasive procedure at that future time.

Biomarkers for neurological conditions

Low molecular weight (LMW) peptides have been discovered that are indicative of neurological conditions, such as Alzheimer's Disease (AD), cognitive impairment and brain microhemmorhages. Evaluating patient samples for the presence of such LMW peptides is an effective means of detecting neurological conditions and monitoring the progression of the disease. The LMW peptides are particularly useful in detecting neurological conditions during the early stages without invasive procedures.
