    Abstract: Disclosed is a pericardiocentesis needle component (10), comprising a guide wire (13) and a puncture needle (12). The guide wire (13) extends into and through the puncture needle (12), and the guide wire (13) comprises a bent section (32) at the distal end and a straight section at the proximal end. The bent section (32) at the distal end is formed by bending the guide wire (13), and the end of the bent section is a pointed-shape structure. The guide wire (13) is made of a highly elastic material. The pointed end rotates at least 90 degrees within a range of no more than 3 mm starting from the pointed end at the bent section (32) of the guide wire. The pericardiocentesis needle component (10) of the present disclosure is less likely to damage a heart during a pericardiocentesis procedure.

  • Publication number: 20170303960
    Abstract: A surgical access port for passage through body tissue to provide access to an underlying tissue site is provided. The access port has a working channel dimensioned for receiving a surgical instrument and a seal assembly for providing a substantial seal before, during and after insertion of a surgical instrument. The seal assembly includes an instrument seal and a zero seal. The instrument seal includes a proximal base that is interconnected to a distal instrument engaging portion by an elongate supporting portion. The engaging portion has a lateral dimension larger than the lateral dimension of the supporting portion forming a bulbous, mushroom-like head. The lateral dimension of the engaging portion decreases toward a distal opening of the instrument seal such that the distal end of the engaging portion is substantially perpendicular to the seal axis. The supporting portion closely conforms to an inserted instrument and serves to align the distal end of the seal.

  • Publication number: 20170303998
    Abstract: A microwave ablation system incorporates a microwave thermometer that couples to a microwave transmission network connecting a microwave generator to a microwave applicator to measure noise temperature. The noise temperature is processed to separate out components of the noise temperature including the noise temperature of the tissue being treated and the noise temperature of the microwave transmission network. The noise temperature may be measured by a radiometer while the microwave generator is generating the microwave signal or during a period when the microwave signal is turned off. The microwave ablation system may be configured as a modular system having one or more thermometry network modules that are connectable between a microwave applicator and a microwave generator. Alternatively, the modular system includes a microwave generator, a microwave applicator, and a microwave cable that incorporate a microwave thermometry network module.

  • Publication number: 20170304002
    Abstract: The present disclosure describes methods for intracellular electromanipulation of proteins using nanosecond pulsed electric fields (nsPEFs). The nsPEFs have effects on proteins in addition to permeabilizing cellular membranes. The nsPEFs induce a Ca2+-dependent dissipation of the mitochondria membrane potential (??m), which is enhanced when high frequency components are present in fast rise-fall waveforms. Ca2+ is shown to have little or no effect on propidium iodide uptake as a measure of plasma membrane poration and consequently intracellular membranes. Since Ca2+-regulated events are mediated by proteins, actions of nsPEFs on proteins that regulate and/or affect the mitochondria membrane potential are possible. Given that nsPEF-induced dissipation of ??m was more effective when high frequency components were present in fast rise time waveforms, the effects on proteins are due to these high frequency components.

  • Publication number: 20170304003
    Abstract: Disclosed herein are optical assemblies having thin, low profile shapes. These optical assemblies may be used with fiber coupled lasers and other light sources, including high power sources, to irradiate tissue at a wavelength suitable for inducing ablation or coagulation to a target depth, denaturation, thermal modification of a tissue, and/or preferential injury to a target tissue structure. Example optical assemblies can produce substantially uniform illumination patterns that are useful for treating superficial tissue, including the internal or luminal (e.g., esophageal) tissue. Some examples may have capability for cooling superficial tissue or skin, such as a detachable, reusable heat sink for active cooling without consumables, fluid pumps, or other cooling equipment.

    Abstract: Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.
