The present invention concerns an implantable access device and a method for preparing the device. According to the invention the device comprises a shape memory base structure with a biological substructure suitable for cell adhesion, cell engraftment and proliferation for use in transferring and transporting fluid mixtures (blood, suspensions, drug formulations, emulsions, cell suspensions) in/into/out of a human or animal body.

Some embodiments of a medical device anchor system include an anchor device that secures a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors. In some implementations, the anchor device can be installed using a technique in which the subcutaneous anchors undergo relatively little or no flexing when being inserted through the skin into the subcutaneous region between the skin and underlying muscle tissue which may be occupied by fatty tissue.

In certain systems disclosed herein, one or more of a first vascular access port and a second vascular access port can be selected by a customer. Each of the first and second vascular access ports can be implanted subcutaneously within a patient, and each can include a base configured to be attached to a vessel, a body that extends away from the base, and a guidance passageway that extends through the body and the base and includes a funnel region. A maximum height defined by the base and body of the second vascular access port can be greater than a maximum height defined by the base and body of the first vascular access port.

Ports for accessing a vessels within a patient include passageways that can guide needles or other access devices directly into the vessels. The ports can be implanted subcutaneously within a patient. Some ports may be used in the creation and use of vascular access buttonholes.

An implant for the sustained subcutaneous release of an active ingredient, which implant comprises a housing, which is delimited on a first side by a septum, and an outlet on a second side for the release of an active ingredient, and a reservoir, which is arranged in a cavity of the housing and is designed to receive a liquid containing an active ingredient.

Various embodiments of an intraosseous port configured for subcutaneous placement within a patient. Some embodiments include a pair of cavities, each cavity including a septum for receiving a needle. Other embodiments include a graft extending between the cavities. Each cavity is coupled with a lumen extending into a cavity of a bone during use, e.g., a medullary cavity. A method includes extracting a bodily liquid from the bone cavity and returning the bodily liquid back to the bone cavity. Some methods include performing hemodialysis via the intraosseous port.

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.

A skull implant medication injection port comprises: a mounted portion placed on an upper section of a port insertion hole in a patient's cranium and a medication inlet on a top surface; a medication injection diaphragm that seals the medication inlet of the mounted portion where a needle for injecting a medication is inserted; a medication storage portion coupled with a bottom of the mounted portion stores the medication injected through the medication injection diaphragm; a medication discharge pipe connected to the medication storage portion discharges the medication stored in the medication storage portion; and a rib formed on a perimeter between the mounted portion and the medication storage portion that has a diameter larger than an inner diameter of the port insertion hole. A height of the mounted portion is generally about 4 to 7 mm, and a height of the medication storage portion is generally about 2 to 4.2 mm.

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.
