Abstract: A soft tissue biopsy device including: an elongated handle including a gripping member; an elongated flexible shaft mechanically comprising a hollow distal sampling portion with an internal lumen and a distal opening facing a soft tissue; a driving unit configured to rotate the sampling portion with a speed in a range of 100 rounds-per-minute (RPM) to 10,000 RPM while the sampling portion axially advances into said soft tissue.

Abstract: A biopsy assembly, including: a biopsy tube defining a lumen; a tissue penetrator having a distal tip shaped to penetrate through tissue, wherein the tissue penetrator is positioned within the lumen and comprising: an elongated flexible body shaped and sized to move within the biopsy tube lumen; a collapsible distal cutting portion coupled to the body and extending out from the lumen in an expanded state, and configured to collapse to a width smaller than an inner width of the lumen in a collapsed state, wherein the collapsible distal cutting portion comprises a distal sharp cutting edge, configured to perform a thin cut through the tissue, wherein in an expanded state a maximal width of the cutting portion is larger than an inner width or an inner diameter of the biopsy tube lumen.

Abstract: An embodiment of the invention relates to an apparatus for determining a location of a surface of an internal organ of a body, the apparatus comprising: a marker support (12) having proximal and distal ends, an axis, a collapsed state and a deployed state, the marker support (12) comprising: at least three flexible filaments, which in the collapsed state lie within a relatively small radial distance from the axis of the marker support (12), and in the deployed state, each filament forms a loop, the loops each configured to abut a surface of an internal body tissue at an abutment region of each filament; and at least three tissue markers (28), each tissue marker (28) located at an abutment region of a filament; wherein projections of each of the abutment regions on a plane perpendicular to the axis of the marker support (12) each lie along a side of a polygon.

Abstract: A fastener assembly including an existing polyaxial pedicle screw that has been previously installed in a spinal structure, the polyaxial pedicle screw including a polyaxial head to which a prosthetic member is secured, a fastening portion fastened to the polyaxial head over the prosthetic member, and a connector element that extends from the fastening portion, the connector element being connected to another spinal structure.

Abstract: A system including a positioning member (10) including a flexible member (12) which is reversibly deformable between a first deployment configuration and a second deployment configuration, at least one vasculature abutment member (40) located on the flexible member (12) for abutting against structure (17) in a vasculature of a patient, and a delivery system (22) connected to the positioning member (10) for delivering the positioning member (10) to the structure (17) in the vasculature of the patient and for deforming the flexible member (12), wherein in deforming between the deployment configurations, the flexible member (12) undergoes eversion.

Abstract: A fastener assembly including an existing polyaxial pedicle screw that has been previously installed in a spinal structure, the polyaxial pedicle screw including a polyaxial head to which a prosthetic member is secured, a fastening portion fastened to the polyaxial head over the prosthetic member, and a connector element that extends from the fastening portion, the connector element being connected to another spinal structure.

Abstract: A method including affixing an anterior mechanical supportive fastener to anterior portions of adjacent spinal structure by introducing the fastener from a posterior portion of a vertebra and passing the fastener through a curved portion to the anterior portions and fastening the fastener to the anterior portions.
