Publication number: 20190247136Abstract: Devices and methods for protecting and transporting medical probes including, but not limited to, ultrasound transducers and more specifically ultrasound transducers designed for transesophageal echocardiography (TEE). A transport apparatus may include a housing for protecting a control housing of a medical probe and an elongate member extending from the housing. The elongate member may be configured to engage the insertion tube of the probe and maintain an arch shape of the insertion tube during transport to prevent damage from over-flexing of the insertion tube.Type: ApplicationFiled: February 9, 2018Publication date: August 15, 2019Inventors: LEVI MOORE, PETER LEONHARDT

Publication number: 20190247137Abstract: In some examples, a medical device package may include a backing card that is configured to secure a medical device to a major surface of the backing card. The backing card is configured to be assembled from an open state into a closed state in which flaps on one or more ends of a central region of the backing card move over some of the central region and cover some of the secured medical device. The closed state defines a reduced footprint relative to the unfolded state. The backing card may be sealed in a pouch, which may then be housed in a carton. The carton includes exterior walls that enclose the sealed backing card and spacing elements that receive the sealed backing card at a relative location within the carton and holds the backing card a threshold distance from the exterior walls of the carton.Type: ApplicationFiled: February 15, 2018Publication date: August 15, 2019Inventor: John Gallagher

Publication number: 20190247138Abstract: A tissue expander is disclosed herein. The tissue expander may comprise a shell defining a chamber, and having a flexible wall and a port disposed through the flexible wall. The shell may also include a channel disposed through the flexible wall. A first syringe containing a first volume of a liquid may be connected to the chamber of the tissue expander via the channel. A second syringe containing a second volume of the liquid may be connected to the chamber via the port at least approximately one week after the first volume of liquid is injected. The first volume of liquid may be injected more quickly than the second volume of liquid.Type: ApplicationFiled: February 9, 2018Publication date: August 15, 2019Inventors: Gordon Lamar KIRCHHEVEL, David Henry TAFFE

SYSTEM(S), METHOD(S) AND DEVICE(S) FOR THE PREVENTION OF ESOPHAGEAL FISTULA DURING CATHETER ABLATION
Publication number: 20190247139Abstract: The present invention is directed to systems, devices and methods for trans-septally delivering carbon dioxide through a minimally invasive catheter to create a gaseous pocket or emphysema between the posterior wall of the left atrium and the esophagus during cardiac ablation of the left atrium. This pocket of gas expanded tissue serves to thermally insulate and separate the esophagus from the left atrium during ablation to prevent the formation of an atrial-esophageal fistula. The system comprises a control system to precisely deliver the gas to a desired location through a needle-based catheter assembly.Type: ApplicationFiled: September 11, 2018Publication date: August 15, 2019Inventors: William Cohn, Colin Brahmstedt, Matthew Kuhn, Fergus Wong -
Publication number: 20190247140Abstract: A disposable material, pre-cut to various shapes or able to be cut or shaped at the time of use, to protect non-target tissue, excluding the eyes, during treatment of the skin is disclosed. The disposable material comprises a flexible material comprising at least one first layer comprising a material that mitigates the transmission of electromagnetic radiation from an radiation source; a backing layer that is located on top of the first layer and is configured to diffusively reflect the electromagnetic radiation without direct specular reflection; and an adhesive for removably attaching the disposable material to the skin. There is also disclosed a method of protecting non-target tissue, excluding the eyes, by applying the disclosed material to a desired location.Type: ApplicationFiled: February 8, 2019Publication date: August 15, 2019Inventor: Eric F. BERNSTEIN

Publication number: 20190247141Abstract: An electrosurgical assembly that includes one or more electrodes, and one or more AC conductors electrically connecting the one or more electrodes to a power source that is configured to generate and output an AC power signal to the one or more electrodes via the one or more AC conductors. A rectifier is electrically connected to the one or more AC conductors, and configured to convert the AC power signal into a DC power signal. A light source is electrically powered by the DC power signal.Type: ApplicationFiled: February 12, 2018Publication date: August 15, 2019Inventors: Kester J. Batchelor, Riyad Moe, Huisun Wang

Publication number: 20190247142Abstract: The invention relates to an image processing method and a medical observation device (1) such as a microscope (2) or endoscope. The device and method are used for displaying output image data (54) of soft biological tissue (12). In image-guided surgery, pre-operative three-dimensional image data (6) of the soft biological tissue (12) are elastically matched to interoperative image data (14) which are acquired during surgery. By displaying the elastically matched pre-operative three-dimensional image data (6) together with the interoperative image data (14), the surgeon may be made aware of the consistence of the soft biological tissue (12) below the visible surface layer. Existing systems for image-guided surgery need to be manually readjusted if surgery is done on soft biological tissue (12), which may deform and shift.Type: ApplicationFiled: February 7, 2019Publication date: August 15, 2019Inventor: George THEMELIS
