  • Publication number: 20180125570
    Abstract: An electrosurgical device can be delivered to a tissue site to provide supplemental sealing of vessels and/or vascular tissue that include suturing, stapling, or the like. The electrosurgical device is generally in the form of forceps, and includes an end effector assembly including opposing movable jaws. Each jaw includes a deformable pad or cushion including an electrode array positioned thereon. Each deformable cushion is configured to deliver a fluid, such as saline, during activation of the electrode array, thereby creating a virtual electrode which couples radiofrequency (RF) energy emitted from the electrode array into tissue in which the RF energy is converted into thermal energy. The deformable cushion and electrode array provide a controlled degree of compression upon the target tissue or vessel to maintain integrity of a suture, staple, or clip, as well as controlled energy emission for sealing, cauterizing, coagulating, and/or desiccating the target tissue or vessel.

  • Publication number: 20180117251
    Abstract: A wearable drug delivery device has a needle assembly and a drug vial arranged side-by-side. This arrangement makes the device compact so that it can be easily worn around a user's wrist, for example. When the user triggers the device to inject a dose of medication like epinephrine, in an orchestrated sequence, a first spring drives the needle assembly downward and inserts a needle into the user while connecting the needle assembly to the drug vial. A second spring then delivers the dose from the drug vial through the needle and into the user. Advantageously, the small form factor encourages the user to wear the device and have lifesaving medication at the ready.

  • Publication number: 20180104004
    Abstract: The present invention is directed to a medical device for providing treatment to diseased tissue and cells. The medical device is configured to ablate a target tissue surface, optionally within a resection cavity, and further deliver a therapeutic that targets diseased (e.g., cancer) cells via a marker whose expression is upregulated by the ablation. The ablation directly kills diseased cells associated with the tissue surface. While some diseased cells evade direct ablation, those cells nevertheless upregulate certain cell surface markers in response to the ablation, even while other, healthy or normal cells do not upregulate expression of the marker in response to the ablation. Devices and methods disclosed herein are used to deliver a therapeutic that uses the upregulated cell surface marker to cause the death of those diseased cells.

  • Patent number: 9814519
    Abstract: A tissue ablation probe comprises an electrically conductive probe shaft, at least one electrode, and an electrically insulative sheath disposed on the probe shaft. The insulative sheath has thickened regions forming alternating ribs and depressions that longitudinally extend along the probe shaft. The ribs allow the ablation probe to be delivered through a tightly toleranced delivery device. While the ribs may shear off during the delivery process, the underlying probe shaft will remain covered by the remaining portion of the insulative sheath. The tissue ablation probe may be used in a tissue ablation assembly that additionally comprises a delivery cannula having a lumen in which the tissue ablation probe may be removably disposed. In this case, the sheath has an outer periphery having a size substantially the same as the diameter of the lumen, so that the inner surface of the delivery cannula cooperates with the depressions to create lumens that longitudinally extend within the cannula.
