Fluid delivery systems and methods of delivering a therapeutic agent are disclosed that include a subcutaneously implantable port that can be easily and efficiently located through the tissue of a patient. The port includes a body that defines a chamber having an open top, a delivery opening, and a catheter connection portion, and a septum disposed on the body, where the septum includes a lower surface extending over the open top of the chamber and an opposite, upper surface. The port further includes a cap of the port that defines an opening extending therethrough and the cap is configured to be coupled to the body to secure the septum within the port with the opening of the cap providing needle access to the septum. The cap includes a downwardly tapered surface that extends around the opening and is configured to direct a needle towards the upper surface of the septum.

A venous access port assembly (10) having a housing base (28) with a discharge port (16), a septum (14) and a cap (48). An interior reservoir (22) is defined by a well (30) in the housing base and a bottom (62) of the septum, and a passageway (20) extends from the reservoir through the discharge port (16). The housing base (28) is provided with radiopaque markings (60) on the bottom wall (44) thereof, including radiopaque indicia (70) that identify an attribute of the assembly (10) after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute.

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.

Subcutaneous access hub embodiments are discussed herein that include housing embodiments having a plurality of cannula ports and a fluid passageway network that allows fluid communication between a fluid source and the plurality of cannula access ports. Such a configuration may allow a user such as a patient or clinician to releasably secure the housing to an outside surface of the patient's skin. Multiple locations on the patient's skin may then be accessed for deployment of one or more delivery cannulas via a plurality of cannula ports for delivery of fluid and from the fluid source to multiple subcutaneous locations below the patient's skin and timely movement of cannula access in the patient's skin without the need for relocating the housing.

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.

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.

A pain management system with a neuromodulation subsystem includes a medication dispenser located external to a patient. A subcutaneous port is placed internally to the patient and receives a quantity of medication. The port can be filled from a syringe or medication dispensing system. An echogenic catheter can be placed in proximity to a patient's nerve or nerve center using a point-of-care ultrasound imaging system. A pain management method includes the steps of placing a subcutaneous port using ultrasound imaging for guidance and administering pharmacologic agents via a catheter connected to the port. Neuromodulation can be applied as an alternative to or in conjunction with medication. Alternative embodiment catheter systems include echogenic tips, a stylet, and multiple internal coil sections to facilitate accurate placement. Alternative embodiment pain management methods include the steps of utilizing such features for optimizing patient outcomes.

A port (1) for a catheter comprises: a housing (10) having a base plate (12); a cavity (140) arranged in the housing (10) for receiving a fluid; a membrane (13) attached to the housing (10) and arranged on an opening (102) of the housing (10) for sealing the opening (102) such that the cavity (140) is enclosed in the housing (10) in a fluid-tight manner; and a connector (15) for connecting a catheter (2) to the housing (10) to provide a fluid connection between the cavity (140) and the catheter (2). The port (1) has an outer shape defined by the housing (10) and the membrane (13) attached to the housing (10). In addition at least one adapter piece (3, 4) is provided, the at least one adapter piece (3, 4) in a preassembly state being separate from the housing (10) and being attachable to the housing (10) to alter the outer shape of the port (1), wherein the port (1) is operational with or without the at least one adapter piece (3, 4) attached to the housing (10). In this way a port is provided which in a uniform manner may be used with different patients.

A dual reservoir access port includes a base having proximal and distal fluid reservoirs. The fluid reservoirs each comprise a bottom and a side wall. A dual prong outlet stem projects from a distal end of the base and comprises a first prong and a second prong. A first fluid channel extends through the first prong to the distal reservoir, and a second fluid channel extends through the second prong to the proximal fluid reservoir. A puncture shield is disposed between at least a portion of the second fluid channel and the bottom of the distal fluid reservoir. A needle-penetrable septum is disposed atop of each of the fluid reservoirs. A cap is placed over and around the port base compressing and sealing the septa against the base. A locking collar may be placed over a dual lumen catheter to lock the catheter to the dual prong outlet stem.

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.
