Abstract: A biopsy assembly including a biopsy catheter having a proximal portion and a distal portion, a navigation catheter configured to receive the biopsy catheter for positioning the biopsy catheter adjacent target tissue, wherein the biopsy catheter is configured to be received within the navigation catheter, a coring component, and an anchoring component configured to anchor the biopsy catheter to target tissue. The coring component includes a proximal region and a distal region, the distal region formed of one or more distally extending blades and the proximal region being coupled to the distal portion of the biopsy catheter and the one or more blades are configured to penetrate target tissue and sever a tissue sample from the target tissue.

Abstract: Method and apparatus for quantitative and qualitative determination of heart rate, stroke volume, cardiac output, and central fluid volume. Phonocardiography based technique using multiple transducers and multi-sensor processing algorithms provides a non-invasive method of evaluating the output of the heart. This basic system coupled with additional sensor elements provides a wide range of potential capabilities. A system comprising these techniques in a wearable form provides a non-invasive method of determining hydration status and blood volume status. Phonocardiography augmented with multi-sensor signal processing techniques improves signal quality to analyze heart sounds and associated features (e.g. S1 and S2, amongst others). Noise compensation and cancellation techniques for phonocardiography further improve signal to noise ratio to reject external disturbances.

Abstract: An implantable device and method are disclosed for stenting an occlusion of an airway. The implantable device includes a cylindrical tube shaped proximal region, a flared distal region, and a non-bifurcated single lumen extending through the device. The proximal region defines a proximal portion of the lumen and the distal region defines a distal portion of the lumen. The distal region may flare outward laterally at a first angle and anteroposterior at a second angle, thereby forming an elliptically shaped distal opening to the lumen. The distal edge of distal opening may lie entirely in a plane orthogonal to a longitudinal axis of the device. Alternatively, the distal edge may be non-planar, such as concave or convex, when viewed in an anteroposterior direction. The implantable device may be formed of a scaffolding structure.

Abstract: Aspects of the present invention are generally directed to a biopsy device configured to engage target tissue within a patient and to remove a sample of the target tissue from the patient. The biopsy device comprises an elongate catheter configured to be inserted into a patient. A coring component is disposed at the distal end of the catheter to sample the target tissue.

Abstract: An endoscope securement device for coupling an endoscope to the body of a practitioner. The endoscope securement device includes a base capable of being coupled to a practitioner and an articulable arm extending from the base configured to be coupled to an endoscope. The device allows a practitioner to manipulate the endoscope through his or her body movements, leaving his or her hands free to manipulate accessories to the device or other tools.
