  • Patent number: 10307179
    Abstract: Pericardial modification devices and methods can be used for the treatment of heart conditions. For example, this document describes devices and methods for treating heart failure with preserved ejection fraction, including diastolic heart failure, by performing a pericardial modification procedure. In one example embodiment, a method for treating diastolic heart failure includes creating an opening in a patient's pericardial tissue, or removing a portion of the patient's pericardial tissue. The creation of the opening or the removing of the pericardial tissue reduces pressure exerted by the pericardial tissue on the patient's heart. The pericardial modification procedures are performed while avoiding trauma to the epicardial surface of heart as well as the phrenic nerves.

  • Patent number: 10195366
    Abstract: An injection analgesia system advantageously numbs a patient's skin around an injection site. An injection window guides a caregiver's injection placement to a relatively small area while allowing standard injection procedures to be followed, such as stretching the skin and puncturing the site with a jabbing motion. The injection analgesia system has a needle shield and an analgesia, which are layered together and applied to a skin surface. A needle shield window and a analgesia window align to form the injection window. Advantageously, the needle shield may fold and/or wrap around the injection needle for sharp object protection during and after needle disposal.

  • Patent number: 8801665
    Abstract: An injector for delivering an injectate into the myocardium of the heart may be implemented as a catheter or a handheld unit. The injector includes a body, a stabilizer secured to a distal end of the body, and a needle that may be controllably advanced from the distal end of the body. The stabilizer stabilizes the distal end of the body relative to the myocardium while the heart beats. An enlarged region disposed along the needle prevents the needle from being advanced into the myocardium beyond a desired penetration depth. To make an injection, the physician brings the distal end of the body in proximity to the myocardium, actuates the stabilizer to stabilize the distal end relative to the myocardium, and advances the needle into the myocardium. Advancement of the needle is impeded by the enlarged region, thereby placing the needle tip at the desired penetration depth for the injection.

  • Patent number: 8603031
    Abstract: A device and method for accessing a pericardial space of the heart includes a shaft having a cavity at a distal end, a suction lumen terminating in a distal port within the cavity and a hollow needle having a distal tip extending into the cavity. The cavity may be a recess in the shaft into which the distal tip of the needle fixedly protrudes. In other embodiments, the cavity is formed by an inflatable member positioned at the distal end of the shaft and the needle is slidable relative to the shaft. Suction is applied at the cavity to draw a pericardial bleb. The needle pierces the pericardial bleb for accessing the pericardial space and also facilitates delivery of payloads into the pericardial space.

  • Patent number: 8579862
    Abstract: Provided is a microneedle device which protects microneedle, has an easily portable shape, is free from such problems as breakage of small needles in the step of puncturing the skin with the microneedle, and ensures appropriate skin puncture for administering a drug. By studying the relationship between a device to be pressed to the skin and the height of an elevation on the skin surface under the pressing and thus producing a device equipped with microneedle that are embedded in a concave part having a definite depth, the microneedle can be surely and easily inserted and punctured into the skin while avoiding such problems as breakage of the small needles of the microneedle. Thus, a microneedle patch formulation, which is easily portable and ensures convenient drug administration to the skin, can be produced.

  • Patent number: 8545444
    Abstract: A system for administering pain-free injections includes an electric current source having at least two electrodes attached adjacent an injection site, the electric current source producing a variable numbness pattern and providing a frame of reference for identifying a plurality of sub-areas of the injection site; and a probe applied to the plurality of sub-areas of the injection site for pain-response testing, wherein one or more areas of numbness in the variable numbness pattern are identifiable according to the plurality of sub-areas of the injection site. A fence may be removably applied to the injection site and provide a frame of reference for identifying a plurality of sub-areas of the injection site, and may aid in identifying one or more areas of numbness in the variable numbness pattern. The fence may be removably applied to the injection site via a belt or manual pressure.

  • Publication number: 20130231612
    Abstract: An injection device that comprises a chamber configured for containing a substance to be injected and a needle operatively associated with the chamber and having a length sufficient to deliver the substance to an intradermal injection site. A collar surrounds the needle, defining a collar cavity. The collar also has a peripheral forward skin-contacting surface that surrounds and is radially spaced from the needle and injection site by an area that is sufficiently large to allow a patient's skin to move into the collar cavity to properly position the needle for intradermal delivery of the substance to the injection site to allow spread of the injected substance under the skin while inhibiting or preventing backpressure within the skin from forcing the substance out through the injection site.

  • Patent number: 8523894
    Abstract: The present invention relates to a compression device for stimulating the efflux of a body fluid from a body part. The device has a compression unit with a pressure-application region made of a deformable material, the region being formed to generate a repulsive force between the body part and the compression unit. The repulsive force passes through a force maximum then decreases to serve as an indication that the body part is guided sufficiently firmly and far enough onto the compression unit.

  • Patent number: 8388579
    Abstract: Apparatuses and methods for performing and aiding venipuncture. The apparatuses of the present invention provide the medical practitioner with an improved tool for performing venipuncture methods. The apparatus preferably includes a handle that is connected to a plurality of tines that run roughly parallel to one another. During use, the tines of the apparatus are pressed against the skin of the patient such that they sit astride the vein to be accessed. The distance between the various tines of the present apparatuses varies so as to be able to accommodate a variety of vein widths. The apparatuses of the present invention may have tines at either one or both ends of the body of the apparatus. The apparatuses of the present invention may be used with a variety of vein accentuating devices, such as those that employ light to accentuate the vein to be punctured.
