  • Patent number: 9427143
    Abstract: A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, adjacent chambers being fluidly connected, and a fluid source attached to one end of the set, such that the chambers inflate sequentially. The chambers are constructed of an elastic material and have a wall thickness and dimensions such that they have a characteristic with a non-monotonous relationship between the inflation pressure within the chamber and the chamber's inflated size. The characteristic is such that after an initial inflation pressure peak, the non-monotonous relationship adopts a negative slope, such that the volume of the chamber increases more rapidly than the volume of fluid flowing into it, and the inflation pressure of the chamber falls. This effect causes the chamber to inflate and anchor rapidly, while essentially slowing down the inflation of the succeeding chamber until inflation of the first is complete.

  • Patent number: 9415234
    Abstract: The accuracy of tissue heating in a body when using a phased array hyperthermia system can be improved by using, in conjunction with the hyperthermia system, a program for predicting heating patterns within the tissue based upon a selected E-field value at each of the antenna energy feedpoints. The hyperthermia system includes circuitry necessary to provide information for calculating the complete EM field at each of the antenna feedpoints during treatment, and such calculated actual feedpoint EM fields are feed to the program to be used in place of the otherwise program generated e-fields in predicting the heating pattern produced by the hyperthermia system during treatment. Further initial operating parameters of the hyperthermia system can be set to produce calculated actual EM fields at the antenna feedpoints which approximate the E-field values used by the program in pretreatment optimizing of the heating pattern.

  • Patent number: 9339660
    Abstract: An implantable medical device (IMD) is disclosed having one or more magnetic field sensors for measuring a strength of a magnetic charging field provided by an external charger and used to provide operational power to the IMD, for example, to charge its battery. The measured field strength data, or derivations of such data, are telemetered to the external charger, which further process the received data if necessary and can inform a user whether alignment between the external charger and IMD is sufficient, a misalignment direction, and/or a misalignment distance, so that the user can attempt to improve the alignment of the external charger. The one or more sensors are preferably placed at or equidistantly around a center axis of the IMD's charging coil. However, the sensors may be placed at any number of locations in the IPG, and at different distances from the center axis.

  • Patent number: 9277969
    Abstract: Disclosed is a system and method for enabling user preview and control of the size and shape of an electromagnetic energy field used in a surgical procedure. The disclosed system includes a selectively activatable source of microwave surgical energy in the range of about 900 mHz to about 5 gHz in operable communication with a graphical user interface and a database. The database is populated with data corresponding to the various surgical probes, such as microwave ablation antenna probes, that may include a probe identifier, the probe diameter, operational frequency of the probe, ablation length of the probe, ablation diameter of the probe, a temporal coefficient, a shape metric, and the like. The probe data is graphically presented on the graphical user interface where the surgeon may interactively view and select an appropriate surgical probe. Three-dimensional views of the probe(s) may be presented allowing the surgeon to interactively rotate the displayed image.

  • Patent number: 9174024
    Abstract: A steering handle for a catheter. The steering handle includes a thumb knob arrangement for driving a cam assembly that in turn actuates a pull wire or pull wires. In some embodiments, the cam assembly includes a set of dual pins that actuate the pull wire in a quasi-linear relationship between cam rotation and axial displacement of the wire. In certain embodiments, the second set of dual pins imparts a reverse action on a second pull wire, also in quasi-linear fashion. That is, when one wire is released by the cam assembly, the other wire is taken in by the cam assembly. In various embodiments, the quasi-linear action can cause release of more pull wire than is taken in, thereby helping prevent the released pull wire to act as an unwanted counter force to the actuated pull wire.

  • Patent number: 9041616
    Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

  • Patent number: 9031667
    Abstract: A method and device for inducing anaesthesia in mammals by the application of RF energy to create hyperthermia derived neural anaesthesia. An RF generator drives a plurality of electrodes placed in tissue surrounding the target nerve fiber to desiccate the desired length of nerve fiber to be desiccated in a single deployment. The device allows high-speed selection/de-selection of bipolar electrode pairs or sets under continuous RF excitation. Activation of electrode pairs is adapted in response to sensed current density and temperature (by electrodes not in the current discharge activation phase) in order to create lesions of complex and well defined shape necessary for the production of hyperthermia derived neural anaesthesia.
