  • Patent number: 10518064
    Abstract: A catheter assembly for use in accessing a vasculature of a patient is disclosed. In one embodiment, the catheter assembly includes a catheter body that includes a flattened oval outer surface and defines first and second lumens. The catheter body defines a distal tip region that includes a venous lateral opening that is in fluid communication with the first lumen and includes a distal-facing portion. The distal tip region further includes an arterial lateral opening that is in fluid communication with the second lumen, includes a distal-facing portion, and is substantially un-staggered with respect to the venous lateral opening. A distal end opening is in fluid communication with a power injectable third lumen. In another embodiment, the first and second lumens each generally include a reniform cross-sectional shape. In yet another embodiment, a dual-lumen catheter includes first and second lumens that each define a modified ellipse cross-sectional shape.

  • Publication number: 20190231172
    Abstract: Disclosed herein are connection systems for establishing electrical connections across a sterile field. An example connection system includes a sensor connector, a probe connector, and a tether having a first end connected to the sensor connector and a second end connected to the probe connector. The sensor connector includes a piercing element. The piercing element is configured to pierce a sterile side of a drape and establish a first electrical connection with a receptacle of a sensor when the piercing element is inserted into the receptacle. The probe connector includes a probe-connecting means configured for a user to establish a second electrical connection between an electrical contact of the probe connector and a wire probe. The tether is configured to convey electrical signals between the sensor connector and the probe connector. Also disclosed herein are methods of connection systems for establishing electrical connections across a sterile field.

  • Publication number: 20190217054
    Abstract: A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. One method for curving a catheter tube of a catheter assembly includes constraining the catheter tube into a curved configuration using the tube constraint, heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature, and releasing the catheter tube from the tube constraint after the heating is complete.

  • Publication number: 20190134373
    Abstract: A power-injectable access port and methods of making are described. One method of making includes forming a power-injectable access port housing, creating a screen including one or more apertures through the screen in the shape of one or more alphanumeric characters, suspending a radiopaque material in a silicone material to form a radiopaque suspension, and depositing the radiopaque suspension onto a surface of the power-injectable access port housing through the one or more apertures of the screen to create at least one radiopaque identification feature. The at least one radiopaque identification feature may have a thickness protruding from an outer surface of the port base such that it is perceivable by sight and touch prior to implantation of the power injectable access port, and is observable via imaging technology subsequent to subcutaneous implantation of the power-injectable access port.

  • Publication number: 20190111242
    Abstract: An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.

Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. In one embodiment, therefore, a catheter assembly is disclosed, comprising an elongate catheter tube defining at least one lumen, and a tube constraint. The tube constraint is included with the catheter assembly and is configured to temporarily constrain the catheter tube in a curved configuration during a heating procedure of the catheter assembly so as to permanently form the catheter tube in the curved configuration after the heating procedure is complete and the catheter tube is released from the tube constraint.

  • Patent number: 10179230
    Abstract: An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is included on an insert that is incorporated into the access port so as to be visible after implantation via x-ray imaging technology.
