Implantable Port Placement System Including Low-Scarring Exterior
Disclosed herein is a system and a method for streamlining the port placement process. The placement system can simultaneously form an incision, dissect tissue, create a tissue pocket of the correct size for the port being placed, and place the port subcutaneously. In an embodiment, the port includes tunneling features for creating a subcutaneous tissue pocket. In an embodiment, the insertion tool includes tunneling features for creating a subcutaneous tissue pocket. Further, the port includes a reinforced, concave septum that allows for a low overall profile of the port, while still capable of withstanding power injection. This results in reduced procedure times, reduced scarring, and minimized wound management.
Implantable Ports, Implantable Port-Detecting Devices, and Methods Thereof
Disclosed herein is an implantable port and an implantable port-detecting device (“IPDD”). The implantable port includes a housing and a septum over a portion of the housing. At least one of the housing or the septum incorporates a contrast agent for locating the septum of the implantable port when the implantable port is implanted in a patient. The IPDD includes a light source, a light detector, and a display configured to display a presence of the implantable port. The light source is configured to emit light in a near-infrared (“NIR”) range of wavelengths as incident light for absorption by the contrast agent. The light detector is configured to detect light in the NIR range of wavelengths including luminescent light emitted by the contrast agent. The display is configured to display a presence of the implantable port when the luminescent light from the contrast agent is detected by the light detector.
Implantable access port including a sandwiched radiopaque insert
An access port for subcutaneous implantation is disclosed. The access port may include a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. The access port may further 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. 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 a molded insert that is sandwiched between base and cap portions of the access port so as to be visible after implantation via x-ray imaging technology.
Access port locator and methods of use thereof
A method of treating a host having an implanted subcutaneous access port, comprising using an access port locater configured to locate a subcutaneous access port located beneath a skin surface of a host.
Apparatus and method for cannulation of vascular access graft
An apparatus for guiding cannulation with a dialysis needle of an arteriovenous dialysis access graft subcutaneously implanted in a body of a subject. The guiding apparatus comprises an elongated body member comprising a base portion terminating in longitudinal edges, a distance between the longitudinal edges of the base portion being substantially equal to a lateral dimension of the aces graft, and an elongated tubular sleeve defining an pocket having a longitudinal dimension and a lateral dimension configured to receive the body member. The body member is adapted to be received in the pocket of the sleeve for securing adjacent the subcutaneous access graft such that the inner surface of the base portion is aligned with a cannulation point of the graft for guiding location of a needle insertion.
Method and Apparatus for Printing Radiopaque Indicia
A method of printing radiopaque indicia on a medical device. The method includes applying radiopaque marking fluid to a surface of a plate comprising one or more etchings having a depth of at least 0.0001 inches, exposing the radiopaque marking fluid on the surface of the plate to air to allow the radiopaque marking fluid to achieve a sufficient level of tackiness, and transferring the radiopaque marking fluid to a medical device. The radiopaque marking fluid comprises a clear ink and tungsten particulates having a particulate size of more than one micron.
MRI safe tissue expander port
Improvements for use with tissue expanders are provided. A tissue expander includes: a selectively inflatable and deflatable shell that is configured to be implanted; and an access port for selectively inflating and deflating the shell, the access port comprising a sidewall, a base at a first end, and a membrane at a second end opposite the first end, wherein the sidewall and the base of the access port are constructed of a material that is non-reactive with a magnetic resonance imaging (MRI) machine. In embodiments, the tissue expander includes a magnet at the access port. In embodiments, the magnet is configured with a physical size and magnetic force such that, when the tissue expander is implanted, the magnet is detectable by an external magnetometer sensor but is not detectable by an external dangle-magnet.
EXTERNAL-MAGNETICALLY CONTROLLED ACCESS TO IMPLANTED FLUID PATHWAY
An implantable medical pump system configured to selectively permit access to a medicament reservoir by way of at least one contactless key, including an implantable medical pump having an medicament reservoir fluidly couple to an access port via a conduit including an access valve, and at least one contactless key configured to impart a magnetic field upon a portion of the implantable medical pump to manipulate the access valve between a closed position isolating the medicament reservoir from the access port, and an open position fluidly coupling the medicament reservoir to the access port.
