The invention relates to a vascular access device (10) for implantation onto a vessel wall, the access device comprising an tubular structure (12) to provide an access passage into the vessel via a hole in a vessel wall, a connector arrangement (20; 21) for attaching the tubular structure at said hole in the vessel wall, and a membrane structure (16A; 16B) sufficiently flexible to be collapsed for insertion through said hole and to be expanded to lie at least partially against an inner vessel surface thereby to surround the hole. The membrane structure comprises a membrane aperture (18) to provide a passage from inside the vessel into the tubular structure. The vascular access device further comprises a closing mechanism capable of closing the membrane aperture while the membrane structure is expanded against said inner vessel surface. There is also provided a method of implanting a vascular access device.

An access device for placing a medical article within a body space includes a syringe, a needle, and a sheath which are employed together with a guide wire. The sheath can be coaxially and slideably disposed about the needle. During insertion of the sheath over the needle, guide wire and into the body space, the syringe provides a negative pressure to ensure that any air located between the inside diameter of the sheath and the outside diameter of the needle is drawn into the needle rather than into the body space. In certain embodiments, a dilator is coaxially and slideably disposed about the needle and within the sheath.

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.

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.

The present invention relates to surgical access devices (or surgical access ports) and related methods. More particularly, the present invention relates to such devices that are advantageously adapted for use in single-incision laparoscopic surgical (“SILS”) procedures The present invention also relates to kits and methods involving such surgical access devices.

An implantable device includes a low-profile housing having a cavity defined in a side thereof, and an element insertably removable with respect to the housing in a direction substantially parallel to a surgical plane of the implantable device. The element has a first portion adapted to be received in the housing cavity. The element further includes a second portion adapted to protrude from the housing upon insertion of the element into the housing cavity. The second portion includes at least one surface adapted for engagement with a surgical instrument for insertion and removal of the element with respect to the housing. A method for servicing the implantable device includes, at an incision proximate an implant location of the implantable device, insertably and removably accessing the element in a direction substantially parallel to a surgical plane of the implantable device.

An intraosseous access device can include a device body, a trocar needle, and an intraosseous catheter removably disposed on the trocar needle. The device body can be configured to enable a user of the access device to manually insert a distal tip of the trocar needle through a skin surface of a body of a patient to an external surface of a bone of the patient. The intraosseous access device can include a first advancement member configured to provide a first distal advancement force sufficient to distally advance a distal tip of the trocar needle and the catheter through a skin surface to an external surface of a bone of a patient, and a second advancement member configured to provide a second distal advancement force sufficient to distally advance the distal tip of the trocar needle and the catheter through the external surface of the bone.
