Estimating a source and extent of fluid leakage during surgery
Systems and methods for analysis of fluid leakage are disclosed. A system may include at least one processor configured to receive in real time, intracavitary video of a surgical procedure; analyze frames of the intracavitary video to determine an abnormal fluid leakage situation in the intracavitary video; and institute a remedial action when the abnormal fluid leakage situation is determined.
INTRAMEDULLARY NAIL WITH WIRE OR MAGNET FOR TARGETING OF A BONE-ANCHOR LOCKING HOLE
In one embodiment, an intramedullary nail has a body that includes proximal and distal ends and an inner surface that defines at least one locking hole that extends into an outer surface of the body so as to receive a bone anchor to lock the nail in a medullary canal of a bone. The body has a first biocompatible material that defines at least a portion of the outer surface. The nail has a second material that is different from, and at least partially encapsulated in, the first material. The second material can produce at least one of an electrical current and a magnetic field, and is supported by the nail body such that a position of the at least one bone-anchor locking hole can be detected based on the at least one of the electrical current and the magnetic field.
Adjustable implant, system and methods
Aspects of the disclosure relate to an adjustable implant configured to be implanted into a patient that includes an adjustable portion moveable relative to a housing. The adjustable implant may include various smart components for enhancing operation of the implant. Smart components may include a controller for managing operations and a transducer for communicating ultrasound data with an external interface device. Additional smart components may include a load cell within the housing for measuring an imparted load; a sensor for measuring angular position of the adjustable portion; a dual sensor arrangement for measuring imparted forces; a reed switch; a half piezo transducer; and an energy harvester.
SYSTEM FOR THE CONTROLLED FRAGMENTATION OF SOLIDS BY MEANS OF VORTEX SOUND BEAMS
The present invention relates to a system for the controlled fragmentation of solids by means of acoustic beams, comprising at least one acoustic beam generation unit (100); and one feedback and control unit (200) of said generation unit (100). Advantageously, the acoustic beams generated by the system are acoustic vortex beams; and the feedback and control unit (200) further comprises a feedback subsystem (12), configured to receive the information relating to the fragmented solids and to utilize it so as to adapt the operation of the acoustic beam generation unit (100). Given that the generation of shearing stresses is more efficient using vortex beams, the amplitudes of the ultrasonic field needed to fragment the calculi are much lower than in current extracorporeal shock wave lithotripsy techniques. Likewise, the system minimizes unwanted effects on soft tissues surrounding the solid.
FEEDBACK DEPENDENT LITHOTRIPSY ENERGY DELIVERY
A lithotripter is provided that includes a lithotripsy apparatus for treatment of a urinary tract stone by fragmentation. The lithotripsy apparatus includes a lithotripsy wave guide shaft configured to transmit an energy form to at least one urinary tract stone. The lithotripter includes a sensing device configured to provide signal data for determining optimal application of energy during treatment with the lithotripsy apparatus. The lithotripter includes a processor configured to collect the signal data and provide feedback to a user. The processor has a control logic configured to determine at least one of: a) if the lithotripsy wave guide shaft is in contact with a tissue; b) if the lithotripsy wave guide shaft is in contact with a stone; c) type of stone; d) if a user is applying force in excess of a predetermined threshold; and e) physical characteristics of a stone. A method is also provided.
ULTRASOUND BASED THREE-DIMENSIONAL LESION VERIFICATION WITHIN A VASCULATURE
A catheter-based ultrasound imaging system configured to provide a full circumferential 360-degree view around an intra-vascular/intra-cardiac imaging-catheter-head by generating a three-dimensional view of the tissue surrounding the imaging-head over time. The ultrasound imaging system can also provide tissue-state mapping capability. The evaluation of the vasculature and tissue characteristics include path and depth of lesions during cardiac-interventions such as ablation. The ultrasound imaging system comprises a catheter with a static or rotating sensor array tip supporting continuous circumferential rotation around its axis, connected to an ultrasound module and respective processing machinery allowing ultrafast imaging and a rotary motor that translates radial movements around a longitudinal catheter axis through a rotary torque transmitting part to rotate the sensor array-tip. This allows the capture and reconstruction of information of the vasculature including tissue structure around the catheter tip for generation of the three-dimensional view over time.
Methods and system for image guided cell ablation
The invention provides systems and method for the removal of diseased cells during surgery.
Pop-up laminate structures with integrated electronics
A multi-layer, super-planar laminate structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations. A layer with electrical wiring can be included in the structure for delivering electric current to devices on or in the laminate structure.
