Anchors for securing a medical device relative to a body portal, wherein the anchors may accommodate most any implantation trajectory through the portal. Such anchors may further secure the device along any such trajectory without imparting undesirable biasing forces that may shift the device from its intended implanted location. In some embodiments, the anchor is configured as a burr hole anchor including a spherical member contained in a socket of the anchor such that orientation of the spherical member is permitted about three mutually perpendicular axes.

A neurosurgical apparatus includes a guide device and a neurosurgical instrument is disclosed. The guide device includes a tube for insertion into the brain and a head attached to the proximal end of the tube for affixing the guide device to a hole formed in the skull. The head has a passageway therethrough in communication with the bore of the tube such that the bore of the tube and the passageway through the head define an internal channel through which a neurosurgical instrument can be passed into the brain of the subject. The neurosurgical instrument is for insertion to a desired brain target through the internal channel of the guide device. The apparatus includes one or more sealing elements for providing a fluid tight seal between the internal channel of the guide device and the exterior of the neurosurgical instrument to prevent fluid leakage from guide tube.

Some embodiments of an anchor device may include bendable anchor mechanism that is deployable in a subcutaneous layer to releasably secure the anchor device to a patient's body. Certain embodiments of the anchor mechanism may include one or more barbs that flexibly bend in response to an insertion or removal force. As such, the anchor mechanism may be inserted into a subcutaneous layer, and removed from the subcutaneous layer, without the need for a separate actuation device to extend or retract the barbs.

Methods and apparatus for anchoring a catheter to a patient's skin using a catheter anchoring device are described. The catheter anchoring device includes one or more pairs of sharps with a sharpened end configured to pierce the surface of the skin. A locking mechanism for the sharps is used as a failsafe mechanism. The catheter anchoring device further includes a catheter clamp for securing a catheter to the catheter anchoring device. Releasing the clamp allows an operator to reposition and secure the catheter at the new position without moving the catheter anchoring device.

The present disclosure provides a wound closure device including: (a) a first opposing member and a second opposing member disposed on opposing sides of a central axis, each resiliently moveable between a closed position and open position relative to each other, each of the opposing members having a distal edge; (b) skin penetrating means for anchoring the device; (c) a pressure bar along each distal edge; (d) releasable locking means for biasing or maintaining the device in the closed position; and optionally (e) an accessory component.

The invention relates to a fixing device for fixing a medical, cosmetic, decorative or other article to the skin of a living being, the fixing device comprising the following features: a) a first retaining element having a first piercing point, which is designed to pierce the skin, b) a second retaining element having a second piercing point, which is designed to pierce the skin, the second piercing point being arranged at a distance from the first piercing point, c) a bridge, to which the first and the second retaining element are fastened, d) a fixing portion, which is connected to the bridge or is part of the bridge, the fixing portion being designed to fix the article that is to be fixed.

An attachment device used to attach appliances to tissue can incorporate microstructures. A medical device system can comprise a coupling device comprising a base layer, a coupling attached to an air side of the base layer, a microstructure attached to a skin side of the base layer and a patient interaction feature, and an appliance comprising a structure mounted to the coupling to interface with the patient interaction feature. An appliance device comprises a base layer, an appliance structure attached to an air side of the base layer, and a microstructure attached to a skin side of the base layer. An appliance attachment system comprises an appliance, a first component comprising an adhesive backing containing microstructures that are configured to attach to skin, and a second component configured to attach the appliance to the first component.

Some embodiments of a medical device anchor system include an anchor device that receives a medical instrument (such as a catheter or the like) and secures the instrument in place relative to a skin penetration point. In some circumstances, the anchor device may allow the anchor device to be used after medical instrument is already in place without the need for a second penetration point for the anchor device.

A method of making a barbed microcatheter having fluid egress openings includes obtaining a barbed microcatheter blank having a hollow tube with a proximal end, a distal end, and an elongated lumen that extends between the proximal and distal ends of the hollow tube, and first and second flattened regions that extend along opposite sides of the hollow tube. The method includes removing material from the first and second flattened regions of the barbed microcatheter blank to form barbs projecting outwardly from the opposite sides of the hollow tube, and using cutting elements for forming fluid egress openings in a wall of the hollow tube that are in fluid communication with the elongated lumen of the hollow tube. The method includes forming a tissue anchor that is connected with the proximal end of the hollow tube, and securing a surgical needle with the distal end of the hollow tube.

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.
