A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.

Described herein is a medical device including a frame having proximal and distal ends. The frame includes a proximal disc at the proximal end, a distal disc at the distal end, and a connecting segment extending between the proximal end and the distal end and connecting the proximal and distal discs. Each of the proximal and distal discs includes a respective plurality of lobes. Each lobe is defined by a peripheral strut. The medical device also includes at least one patch. The at least one patch is coupled to at least one of the proximal and distal discs of the frame.

An endovascular device, including an elongated flexible sheath defining a lumen with an inner opening sized for enabling selective advancement of an endovascular instrument therethrough, the sheath having at least a first region and a second region; an electrode within the first region of the sheath; and a constrictor associated with the first region of the sheath, the constrictor being configured, while at least the first region and the second region of the sheath are positioned within a body and in response to an input received from outside the body, to reversibly narrow the lumen of the sheath in an area adjacent the electrode to thereby bring the electrode into contact with an adjacent portion of the endovascular instrument.

An endovascular apparatus, including an elongated catheter having an inner lumen extending therethrough; a balloon affixed to the catheter for expansion into the inner lumen of the catheter when the balloon is inflated; and a tube secured relative to the balloon, wherein the tube is configured to enable selective inflation and deflation of the balloon, and wherein an outer diameter of a portion of the catheter adjacent the balloon is substantially the same when the balloon is inflated and when the balloon is deflated.

The present invention introduces a material, i.e. a device, which is insertable into a vein of a outer parts of a sheath, two-sidedly adhesive tubular material with a supporting material and protrusions, either a balong or an inner protective film, and a control cable for the insertion and extraction of the device along the vein. The supporting material may be compressed initially, and after removal of the outer part of the sheath, the supporting material with protrusions will expand towards the vein walls. After removal of the inner part of the sheath and the control cable, the treated vein area can be manually pressed on top of the skin, thus closing the vein through inner and outer adherence of the material. The protrusions may have a barbed shape.

In various embodiments, a system for delivering an implantable device inside a body cavity includes: 1) a core cannula; 2) an access sheath; 3) an injection apparatus for filling the implantable device with one or more fluids; and 4) expanding members operatively connected to the core cannula for preventing the core cannula from advancing through a body orifice once the core cannula and expanding members exist the access sheath. According to particular embodiments, a distal end of the core cannula is pre-attached to the implantable device through a device locking member. In one or more embodiments, upon assessment, an injection apparatus is removed using an injection apparatus handle, the implantable device is detached from the core cannula via a device deployment handle (to be implanted), and the access sheath is removed.

The present application provides an electrode catheter system, comprising an interventional catheter for intervening to one side of an artery blood vessel and provided with an electrode element that can release an electrical signal toward an inner wall of a renal artery blood vessel; a pressure sensor for intervening to an artery blood vessel; and a data processing module, connected with the pressure sensor. The electrode element releases an electrical signal toward the inner wall of the renal artery vessel, and then the pressure sensor monitors a blood pressure change in the renal artery vessel at the other side. A data processing module processes the data monitored by the pressure sensor and determines the blood pressure change, and an activity degree of the nerve can be determined by measuring a signal such as the blood pressure of the human body, so as to screen out the patients with an overactive sympathetic nerve, and a surgical effect of a denervation surgery can also be evaluated before or after the surgery, and can be used to determine whether to perform an ultrasonic ablation again.

A non-transitory computer readable medium containing instructions that when executed by at least one processor, cause the at least one processor to perform operations for monitoring partitioning of a medical instrument during an endovascular procedure. The operations may further be configured to obtain an input to activate a partitioning mechanism associated with a medical instrument within a lumen of a catheter, the catheter being positioned within a body. Further, embodiments may be configured in response to the input, to activate the partitioning mechanism. The operations may further be configured, following the activation, to obtain partitioning outcome data. The operations may determine, based on the partitioning outcome data, whether the medical instrument may be in a severed state or a connected state. The operations may, if the severed state of the medical instrument is detected, output a success notification. Some embodiments may be configured, if the connected state of the medical instrument is detected, to output at least one of (i) a control signal to vary activation of the partitioning mechanism or (ii) an instruction to reposition the medical instrument relative to the partitioning mechanism.

Consistent with disclosed embodiments, systems, devices, methods, and computer readable media for filling a hollow body structure may be provided. In some implementations, an endovascular instrument for filling a hollow body structure may be provided and may include an elongated member configured to exhibit differing coiling properties along a length thereof. The elongated member may include a first region configured to bend within the hollow body structure to form a stabilizing frame. The elongated member may also include a second region located proximal to the first region and configured to bend, after formation of the frame, substantially within the frame, thereby forming a curved mass substantially within the frame. The first region and the second region may be interconnected. The embodiments may further include at least one structural property that differs between the first region and the second region.

The invention relates to a device for closing a vein juncture in the treatment of varicose veins including a catheter which can be inserted into a venous system and at the distal end of which an expandable balloon is arranged, a covering which is arranged circumferentially on the balloon and can be expanded by means of said balloon, wherein the proximal covering end is designed to be open, and at least one adhesion agent for acting on the expanded covering such that it adheres to a vein wall in order to close the vein juncture.
