A low-profile access port for subcutaneous implantation within a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable catheter-bearing needle access to the port without difficulty. In one embodiment, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end, and a receiving cup. The receiving cup is funnel shaped to direct a catheter-bearing needle into the conduit via the inlet port. The conduit is defined by the body and extends from the inlet port to an outlet defined by a stem. A bend in the conduit enables catheter advancement past the bend while preventing needle advancement. A valve/seal assembly is also disposed in the conduit and enables passage of the catheter therethrough while preventing fluid backflow. The body includes radiopaque indicia configured to enable identification of the access port via x-ray imaging.

Disclosed are a subcutaneous port and method of implantation thereof. The subcutaneous port comprising a rigid inner member and an outer member comprising of flexible material connected to the inner member along at least one lateral periphery portion of the inner member, thereby forming a predetermined spatial shape of the subcutaneous port when in an elastically relaxed state. The subcutaneous port is configured to squeeze into a subcutaneous void when pushed through a surgical opening greater than a maximal cross-sectional circumference of the inner member and smaller than a maximal cross-sectional circumference of the predetermined spatial shape.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.

A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.

A medical anchor device (1) for securing a medical article to a subject comprising an upper medical article attachment portion (2) and a lower insertion portion (3) for securing the medical anchor device (1) to the subject wherein the insertion portion (3) comprises a spiral anchor (5) so that the medical anchor device (1) is securable to and detachable from the subject by rotating the medical anchor device (1) in a clockwise or an anti-clockwise manner as required by the direction of the spiral anchor (5).

The device includes a manipulation mechanism for maneuvering a base into position proximate a subcutaneous port. Arms extending from the base enable the device to receive the port and substantially immobilize the port relative to the device. The manipulation mechanism also enables a user to substantially immobilize the device relative to a patient. With the subcutaneous port substantially immobilized by the device, the user has greater confidence and accuracy when inserting a needle into the port. Further, embodiments of the device provide protection to the user to prevent inadvertent sticking of the user as the needle is introduced.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.

An inflatable port including a housing, a chamber in the housing, a septum over the chamber, a hollow stem extending from the housing, and a bladder around at least a portion of the housing. The chamber has a major opening and a minor opening. The septum is positioned over the major opening of the chamber and is fixed to the housing. The stem fluidly connects to the chamber by way of the minor opening of the chamber. The bladder is configured to increase a size of the inflatable port upon inflation of the bladder and decrease the size of the inflatable port upon deflation of the bladder. Also disclosed herein is a catheter assembly including the inflatable port, as well as a method related to the foregoing inflatable port and catheter assembly.

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.
