摘要： A functionalized tip is incorporated into catheters for the cytometric delivery of cells into the brain and other body parts. For use in the brain, the tip forms part of a neurosurgical probe having a proximal end and a distal end. In addition to the functionalized tip, the probe has at least one cell slurry delivery lumen and a plurality of optical fibers configured along the probe, terminating in the tip to provide the photo-optical capability needed to monitor the viability and physiological behavior of the grafted cells as well as certain characteristics of the cellular environment. Details are also presented of the use of a neurocatheter having a cytometric tip of the type disclosed in the invention, as employed within the context of a feedback and control system for regulating the number of cells delivered to the brain of a patient.

摘要： A catheterization device that may be designed by use of an adaptive genetic algorithm computational fluid dynamics approach, as well as other Global Optimization methods that may include simulated annealing, multistart and interval methods, continuous branch and bound methods, evolutionary algorithms, and tabu search and scatter search methods, as well as other available Global Optimization methods that is able to maximize/optimize the dwell time of an infused agent in the vicinity of a vascular lesion. The device may have an internal by-pass channel that allows the blood upstream of the lesion to continue its pulsatile flow through the vessel in the part of it occluded by the lesion, while simultaneously allowing the disbursement and maximal dwell time of an antithrombolytic or other diagnostic or therapeutic agent needed to treat the lesion. Different embodiments of the catheterization device are disclosed and indications for the use of these devices in the treatment of vascular diseases are discussed.

摘要： A system and related method for delivering the anti-tumoral agent carmustine or other types of diagnostic or therapeutic agents into the brain of a patient with a brain tumor includes an insertion device, a skull mount, and a reformulated geometry of the carmustine compound (or other material) optimized for use in the insertion device and for maximized biodegradation time. The insertion device may be front loaded with the carmustine material (or other material) and inserted through the mount on a skull, to the location of the brain tumor, where the carmustine (or other material) is then released. It should be appreciated that the diagnostic and/or therapeutic system and related method thereof are not necessarily limited to the brain of a subject. It may also be used in the organ structures or tubular structures, as well as portions and locations thereof.

摘要： A treatment delivery apparatus comprises a metallic object and a treatment carrier device which is connected by a heat-sensitive biodegradable connector link to the magnetic object. This carrier device contains the treatment, i.e. the drug, to be transported. An electromagnet is positioned outside of the body part for producing a magnetic field which captures the magnetic object. This electromagnet may be either a simple coil system attached to a robotic arm which moves the electromagnet adjacent the body part, or a multicoil electromagnet system surrounding the body part. In either case, the robotically moved electromagnet or multicoil electromagnet system moves the magnetic object within the body part to a desired location. A computer controls either the robotic arm or multicoil current magnitudes and directions. This computer also provides visualization for observing the location and movement of the magnetic object and carrier device. Upon reaching the desired location, the magnetic object is heated, which causes the heat-sensitive biodegradable connector link to melt, which separates the drug-containing carrier device from the magnetic object. The electromagnet means then moves the magnetic object back out of the body part. The treatment-containing carrier device remains in the desired location and the drug is delivered to the specific location.

摘要： An aspect of various embodiments of the present invention system and method provide, but not limited thereto, a novel means for epicardial ablation using a double-curve steerable sheath and a double-curve deflectable open irrigated-tip/suction catheter that can be guided around the apex of the heart and adjusted so as to position the distal tip optimally. The catheter can also both deliver fluid to and withdraw fluid from the pericardial space. Access to the epicardial surface of the heart is via a subxiphoid entry. The method and means presented include, but are not limited to, steering, energy delivery, bipolar mapping, placement and use of electrodes, irrigation, suction of irrigation fluid, and other details of the subject invention.

摘要： Provided is a method and system for delivering a diagnostic agent to a site in the brain of a subject for imaging at least a portion of the brain site on a medical imaging system. The method and system includes a catheter device with associated lumens having diagnostic agent ports for delivering the diagnostic agent (e.g., infusate) through the lumens and advancing the diagnostic agent so as to exit out from the lumens to at least a portion of the brain site and while sealing a portion of the brain site thereby preventing the exited diagnostic agent from travelling proximally beyond the sealing location, and at the same time imaging at least a portion of the brain site during at least a portion of the sealing duration so that the brain site can be visualized on a medical imaging system. The diagnostic agent (infusate) is able to highlight borders and internal patterns of the deep structures of the brain thereby enabling direct targeting. Ultimately this leads to reduced complications, enhanced therapy, and the elimination of the need for awake surgery. The method and system provides the capability heretofore not possible to visualize the small, often indistinct regions, which will greatly improve clinical outcomes with therapeutic interventions.
