Fixation and protective components for use with implantable medical devices, such as access ports and catheters, are disclosed. In one embodiment, a protective sleeve is employed about a catheter so as to distribute compressive loads and ensure patency of the catheter lumen, even in areas prone to pinch-off. A catheter assembly in one embodiment thus comprises an elongate catheter tube that defines at least one lumen. A protective mesh sleeve is disposed about an external portion of the catheter tube so as to cover at least a portion of the longitudinal length of the catheter tube. The protective sleeve is configured to distribute a compressive load on the catheter tube so as to ensure patency of the at least one lumen of the catheter tube.

The present disclosure provides an apparatus for intracranial drug injection including a body unit having a through-hole extending between a first opening in a topmost surface and a second opening in a bottommost surface, a cap unit having a shape corresponding to at least a part of an inner surface of the through-hole and being inserted into the first opening to cover the first opening, and a tube unit having one end coupled to the second opening and another end extending toward an affected brain lesion.

Disclosed herein are medical device systems, and methods thereof. Exemplary medical devices can include intraosseous (IO) access device systems, or similar medical devices that include a motive force. Embodiments include replaceable and rechargeable batteries that are configured to store one or more performance characteristics of the medical device and transfer the performance characteristic to a base station when the battery is removed from the medical device and coupled with the base station for recharging. The base station can then store performance characteristics from one or more batteries and/or medical devices. The performance characteristics can be transferred from the base station to one or more external computing devices or networks.

The present invention relates to a an anti-thrombotic medical instrument and catheter medical instrument comprising: base with a port for connection to an infusion set; a catheter extending from the base, and comprises a main body of tubular configuration. a plurality of lateral conduits distributed along the length of the catheter; an elastomeric cover over each lateral conduit, said elastomeric cover opens with a fluid flow inside the catheter and closes when the fluid flow stops. Said lateral conduits have an angle in the range of 15° to 60° to the longitudinal axis of the catheter.

A flexible portal cannula for use in arthroscopic surgery. Distally positioned flaps extend radially outwardly from the outer surface of the cannula and are resiliently foldable to lie against the outer surface of the cannula during insertion into a surgical portal, and resiliently biased to return to the radially outwardly extending position when unconstrained. A clip disposed on the cannula outer surface outside of an arthroscopic workspace acts to clamp tissue disposed between the clip and the flaps. The clip has an extension to receive pairs of slots to sort and engage the sutures.

Disclosed is a vascular access port selectively changeable subcutaneously from delivery configuration to deployed configuration. The vascular access port includes a port body and a port body extension being partly or wholly disengaged in the delivery configuration, and fixedly connected to form a unified structure of the vascular access port, greater in volume than the port body, in the deployed configuration. Methods and kits for deploying the vascular access port in a body of a subject are also disclosed.

The present disclosure provides an apparatus for intracranial drug injection including a body unit having a through-hole extending between a first opening in a topmost surface and a second opening in a bottommost surface, a cap unit having a shape corresponding to at least a part of an inner surface of the through-hole and being inserted into the first opening to cover the first opening, and a tube unit having one end coupled to the second opening and another end extending toward an affected brain lesion.

Apparatus for delivering therapeutic agents to the central nervous system of a subject is described. The apparatus includes at least one intracranial catheter and a percutaneous access device. The percutaneous access device includes a body having at least one extracorporeal surface and at least one subcutaneous surface, the body defining at least one port for connection to an implanted intracranial catheter. The port is accessible from the extracorporeal surface of the device, but is provided with a seal such as a rubber bung between the lumen of the port and the extracorporeal surface. The percutaneous access device may have more than two ports and/or a flange. A method of implanting the percutaneous access device is also described.

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.

The disclosure relates to a subcutaneously implanted port device for establishing access to the vascular system of a patient requiring multiple blood treatments over an extended period of time. The systems, devices and methods disclosed herein may reduce miscannulation, promote intra-session hemostasis, and decrease the incidence of bacteremia and sepsis among other improvements and advantages. The devices include a port with a tapered seat for receiving an access tube, the first tapered seat having a proximal portion, a distal portion, and a conical section extending between the proximal portion and the distal portion; and an interface surface configured to engage a blood vessel or a vascular access catheter. The proximal portion of the tapered seat is configured to receive the access tube therethrough, and the tapered seat creates a mismatch fit with a diameter of the access tube when in use for an increase in flow during treatment.
