An intracranial stent includes a proximal end, a distal end, and a tubular sidewall extending there between and a patch covering at least a portion of the sidewall; wherein the patch is capable of diverting blood flow past the neck of an intracranial aneurysm. The patch may be made of a photon-activatable material or a tightly woven metal material with a density greater than a density of the sidewall itself.

A method of removing vascular blockage includes providing a catheter system, comprising an outer catheter, a bypass catheter, and a guidewire. In the catheter system, the bypass catheter is slidably disposed within the outer catheter. The method includes positioning a distal end of the catheter system at a proximal end of an occlusion located within a vessel and moving the bypass catheter through the occlusion so that a medicated treatment solution may be delivered through the bypass catheter to an area of the brain or other tissue served by the vessel blocked by the occlusion. Both during and after the delivery of medicated treatment solution to the blocked part of the vessel with the bypass catheter, the physician may engage the occlusion with the perforated segment of the outer catheter so that a thrombolytic agent can be delivered at the occlusion to disintegrate it and then removing at least a portion of the occlusion from the vessel.

Stroke catheter for use in revascularization procedures and method of using same

The present invention provides a method and system for manufacturing cement wherein ground particles of cement and calcium sulfate are subjected to infrared sensors, laser sensors, or both, so that emanated, irradiated, transmitted, and/or absorbed energy having wavelengths principally within the range of 700 nanometers to 1 millimeter can be monitored and compared to stored data previously obtained from ground cement and sulfate particles and preferably correlated with stored strength, calorimetric, or other data values, such that adjustments can be made to the mill processing conditions, such as the form or amounts of calcium sulfate (e.g., gypsum, plaster, anhydride), or cement additive levels. The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.

A method for increasing collateral circulation includes providing a pharmaceutically acceptable synthetic cerebrospinal fluid that has a density different than that of the patient's naturally-occurring cerebrospinal fluid. The synthetic cerebrospinal fluid includes a vasodilator. The method further includes administering the synthetic cerebrospinal fluid to an intrathecal space of a patient through a lumbar access point to reach the intrathecal space of a patient.

Method and composition for alleviating or preventing ischemic tissue damage

Methods and apparatus for analyzing the material properties and behavior of cement as it hydrates under simulated downhole conditions. A wellbore cement simulator includes a temperature and pressure controlled innermost oil-filled container; an annulus in contact with the innermost container configured to hold a cement sample; a mesh sleeve in contact with the annulus wherein the mesh sleeve is water permeable to permit hydration of the cement sample; a steel sleeve in contact with the mesh sleeve; an elastomeric bladder surrounding the steel sleeve; and a temperature and pressure controlled outermost oil-filled container.

Apparatus and methods for measuring confining pressure, axial strain and radial strain of zonal isolation materials are described. This information is useful for evaluating these materials and predicting seal performance and potential failures of these materials.

Confining pressure measurement for zonal isolation evaluation

A method of removing vascular blockage includes providing a catheter system comprising an outer catheter with a serrated cutting element at its distal end, a bypass catheter, and a guidewire. In the catheter system, the bypass catheter is slidably disposed within the outer catheter. The method includes positioning a distal portion of the catheter system at a proximal end of an occlusion located within a vessel and moving the bypass catheter through the occlusion so that a medicated treatment solution may be delivered through the bypass catheter to an area of the brain or other tissue served by the vessel blocked by the occlusion. Both during and after the delivery of medicated treatment solution to the blocked part of the vessel with the bypass catheter, the physician may engage the occlusion with the cutting element by moving the outer catheter in a clockwise/counterclockwise or forward/backward direction within the outer catheter, cutting and then removing at least a portion of the occlusion from the vessel.

Catheter for use in revascularization procedures and method of using same

A pump for delivering a fluid, created by cooling and pressurizing a fluid, into the intrathecal space of a patient, the pump comprising an input channel, an input reservoir in fluid communication with the input channel, a cooling apparatus configured to remove heat from the fluid and a pressurizing mechanism configured to impart pressure to the fluid, an output reservoir, and an output channel, and wherein the output channel is configured to be in fluid communication with a first lumen of a catheter and wherein the first lumen of the catheter is configured to be disposed within the intrathecal space of the patient.

System for cooling and pressurizing fluid

A localizing apparatus includes a frame, a linear reference marker, and a target marker. The frame includes a first portion fixable to a first anatomical reference point. The linear reference marker is rotatable about the first anatomical reference point to align a second anatomical reference point with the first anatomical reference point. The target marker is rotatable about the first anatomical reference point to establish an angle from the linear reference marker such that the target marker is located in a desired plane.

Localizing device for ventriculostomy

The invention relates to compositions, methods, apparatus, and kits for alleviating or preventing vasoconstriction or vasospasm in a mammal. The compositions, methods, apparatus, and kits are also useful for alleviating or preventing ischemic tissue damage resulting from ischemia associated with cerebral vasoconstriction which follows aneurysmal subarachnoid hemorrhage, with embolic stroke, with coronary artery obstruction, and with other conditions. These compositions, methods, apparatus, and kits generally relate to adventitial (i.e., extra-luminal) administration of a nitric oxide donor compound to a blood vessel in a mammal.
