The invention relates to an implant for local active ingredient release having an upper wall (1), which is closed and disk-shaped and consists of a material which is pierceable with an injection cannula using a force of less than 100 N, is self-sealing and is elastically deformable, a lower wall (2) which is arranged opposite the upper wall (1), is disk-shaped, is elastically deformable and has at least one liquid-permeable feed-through (3) through the lower wall (2), a hollow space (4) which is arranged between the upper wall (1) and the lower wall (2), and an anti-piercing means (6), which is disk-shaped, between the upper wall (1) and the lower wall (2), wherein the anti-piercing means (6) consists of a material which is not pierceable with an injection cannula (100) using a force of less than 100 N.

The invention also relates a method for filling such an implant with a liquid.

An implantable device used in a gastric band system includes an access port, a tube coupled to the access port, and a shielding device covering a portion of the tube. The shielding device is positioned adjacent to the access port and covers the end of the tube coupled to the access port. The shielding device is made from a puncture resistant material, to protect the tube from puncture by a misplaced syringe needle inserted by a physician.

An access port for subcutaneous implantation is typically connected to a catheter, a distal portion of which is disposed within a vein or other vessel of the patient. The access port described herein is configured with enhanced fluid handling features to improve fluid flow therethrough while reducing the likelihood of clotting or occlusions in the attached catheter, thus improving system patency. The access port includes a body defining a reservoir, a needle-penetrable septum covering the top opening of the reservoir, a stem including a lumen in fluid communication with the reservoir, and a volume control device positioned in the reservoir. The volume control device includes a floor designed to move from a first position below the side opening to a second position adjacent the bottom surface, and a spring element positioned between the floor and the bottom surface, the spring element biasing the floor in the first position.

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.

A vascular access device with vessel accommodation includes a top portion and a bottom portion. The top portion includes a top vascular housing for encasing a top portion of a vessel when implanted and at least one hollow male member extending from the top vascular housing. The bottom portion includes a bottom vascular housing for encasing a bottom portion of the vessel when implanted and at least one female member disposed at an upward-facing coupling edge of the bottom vascular housing. The at least one female member receives the at least one hollow male member of the top portion to couple the top portion and the bottom portion together such that the top and bottom portions can move vertically with respect to one another but rotation and movement in the horizontal/longitudinal directions are inhibited.

A therapeutic agent injection device including an injection device for delivering a therapeutic agent to a patient having a body, the body having a patient face and a port face opposite the patient face, the port face having an introducer port including an introducer channel and an injection port including an injection channel, the introducer channel being in fluid communication with the injection channel through a cross channel, the injection channel defining an injection axis; a delivery tube for subcutaneous delivery of the therapeutic agent to the patient, the delivery tube projecting from and being generally perpendicular to the patient face, the delivery tube defining an introducer axis and being in fluid communication with the injection port; and a patch, the patch being attached to the patient face and being operable to adhesively attach to the patient; wherein the injection axis is parallel to the introducer axis.

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.

Dural repair devices that are configured to effectively and reliably repair the damage of a dural tear due to incidental durotomies are provided, along with methods of use. The devices and methods enhance the ability of a surgeon to repair a patients dura mater, or dura, during surgery of the central nervous system. The dural repair device has a multi-layer structure configured to exert a pressure or tamponade effect to compress a patient's dura to its state prior to the spinal surgery. Thus, the dural repair devices and methods of use may reduce the patients risk morbidity, further surgery, spinal headaches, or other injuries and discomforts.

A venous access port assembly having a housing base with a discharge stem, a cap, and an interior reservoir. The port assembly is provided with X-ray discernable indicia to identify an attribute of the assembly 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. The indicia are cuts in a reservoir lining of radiopaque material such as metal where the cuts having narrow slot width are in the form of one or more sets of alphabetical letters such as CT in the lining's side wall or bottom wall.
