An intracranial intervention system comprises a seeker wire and delivery catheter used to navigate and access a target location within the intracranial subarachnoid spaces (ISAS) of a patient. A microcatheter is then advanced through the delivery catheter to perform a therapeutic procedure, such as installing a shunt within the ISAS to drain cerebral-spinal fluid (CSF). The shunt may be configured to drain CSF from a first and second ISAS, and includes a distal portion which extends into the first ISAS via the second ISAS and a dural venus sinus (DVS) of the patient. The shunt has a main body portion positioned and secured within the second ISAS, a distal portion extending into the first ISAS and the main body portion in the second ISAS have CSF intake opening which allow CSF to flow into a shunt lumen and out through an outflow opening positioned in the DVS.

Perfusion balloon with internal valve

An apparatus for performing a medical procedure and, in particular, an aortic valvuloplasty, in a vessel for transmitting a flow of fluid. The apparatus comprises a shaft, an inflatable perfusion balloon supported by the shaft and including an internal passage for permitting the fluid flow in the vessel while the perfusion balloon is in an inflated condition, and a valve for controlling the fluid flow within the passage. The valve may be connected to the shaft, or may comprise an elongated tube partially connected to the balloon. The balloon may comprise a plurality of cells in a single cross-section, each cell including a neck, and the valve may be positioned in a space between the shaft and the necks for controlling the fluid flow within the passage. A connector may also be provided to control the position of the valve.

DRUG ASSISTED WOUND DRAINAGE LINE

The wound drainage apparatus for drug-assisted removal of bodily fluids includes a double-lumen tubing member connected to a customizable branched tubing member for placement in a wound cavity. A perforated inner tube connected to an anticoagulant drug delivery pump and a solid outer tube connected to a fluid drainage vacuum make up the double-lumen tubing member. The branched tubing member includes a plurality of secondary wound cavity tubes branching away from a primary wound cavity tube. The apparatus disclosed herein improves upon current drainage systems by preventing occlusions produced by blood clots forming in fluid drainage tubes.

A surgical apparatus for treating a blood clot in a vessel of a patient having an elongated member having an outer wall, a first hole at a distal portion and a second hole spaced proximally from the first hole positioned in a side wall. A first lumen is provided within the elongated member for blood flow through the second hole, through the lumen and exiting the first hole to maintain blood flow during treatment of the blood clot. An energy emitter emits energy to the blood clot or hardenings and a connector connects the energy emitter to an external energy source, wherein blood flows into the second hole positioned proximal of the blood clot and exits the first hole distal of the blood clot during activation of the energy emitter. In some instances when the apparatus is introduced from a retrograde ‘upstream” approach blood may flow through the device in the opposite direction.
