| 20080249458 | Intraventricular Shunt and Methods of Use Therefor - Methods and apparatus for treating hydrocephalus caused by obstructions in the ventricular system and subarachnoid space of the brain. Embodiments include medical devices and methods for use within the subarachnoid space of the central nervous system to gain access to and treat an obstruction within the ventricles of the brain or a subarachnoid hemorrhage. The obstruction may be aspirated by an aspiration catheter for use in the subarachnoid space. A subarachnoid delivery catheter may then be used to deliver an intraventricular shunt to the opening in the obstruction via the subarachnoid space. A distal end of the delivery catheter is navigated across the obstruction to deploy the intraventricular shunt therein. The intraventricular shunt so positioned reopens the pathway between the ventricles and permits the return of normal cerebrospinal fluid flow there through. | 10-09-2008 |
| 20080249501 | Methods for Simultaneous Injection and Aspiration of Fluids During a Medical Procedure - Methods for simultaneous injection and aspiration of fluids during a medical procedure are disclosed. Embodiments include methods for operating medical devices within the subarachnoid space of the spinal column to gain access to the ventricles of the brain, as well as the surrounding cranial subarachnoid space. A dual lumen constant volume aspiration catheter is disclosed that injects a volume of injectable fluid to break up an obstruction within the brain or cranial subarachnoid space while simultaneously aspirating a same volume of aspirated fluid from the treatment site. Methods hereof include constant volume re-circulation of cerebral spinal fluid to and from a treatment area within one of the brain and the surrounding cranial subarachnoid space, which may be desirable during a ventriculostomy. | 10-09-2008 |
| 20090248034 | Method of Diagnosing and Treating Benign Prostatic Hyperplasia - A method of diagnosing and treating a patient having benign prostatic hyperplasia caused by insufficient blood flow to the prostate due to atherosclerosis of a pelvic artery is disclosed. A method of diagnosing the patient's condition includes determining if a stenosis exists within a pelvic vessel. A method of treating the patient's condition may include placing a stent within the stenosed pelvic artery. | 10-01-2009 |
| 20090259296 | Gate Cannulation Apparatus and Methods - A representation of a prosthesis opening is created and a device having a marker is tracked through the opening while monitoring the relative positions of the opening representation and the marker on a display. In one alternative, a representation is made on a display of the center of the contralateral stump opening and an electromagnetic marker coil that is secured to an endovascular delivery device, and the marker and delivery device are guided into the opening, while monitoring the relative positions of the opening center and the electromagnetic marker coil representations. In another alternative, one or more markers are positioned in the vicinity of the prosthesis opening and a device having a marker is tracked to the one or more markers and through the opening where the device is one of a guidewire and a catheter, while monitoring the relative position of the markers on a display. | 10-15-2009 |
| 20100036471 | Method of Diagnosing and Treating Lower Urinary Tract Symptoms - A method of diagnosing and treating a patient having lower urinary tract symptoms caused by insufficient blood flow to the urinary bladder, the urethra, a nerve innervating the urinary bladder, or a nerve innervating the urethra due to atherosclerosis of a pelvic artery is disclosed. A method of diagnosing the patient's condition includes determining if a stenosis exists within a pelvic vessel. A method of treating the patient's condition may include placing a stent within the stenosed pelvic artery. | 02-11-2010 |
| 20100129414 | Bioactive Agent Delivery Using Liposomes in Conjunction With Stent Deployment - Described herein are methods for treating aneurysms, vascular occlusions, and vascular lesions. The methods comprise the use of an implantable medical device which includes a bioactive agent substrate associated with its surface. Liposomes are used to encapsulate the bioactive agent and are delivered either systemically or locally to the bloodstream. A means for liberating the bioactive agents from the liposomes is used once an appropriate location is chosen and the liposomes have distributed themselves through the vasculature. Once liberated, the bioactive agent can be sequestered by the bioactive agent substrate associated with the implantable medical device, and slowly released to impart a therapeutic effect on the surrounding tissues. | 05-27-2010 |
| 20100145222 | METHOD AND SYSTEM FOR MONITORING A NERVE - A nerve monitoring system facilitates monitoring an integrity of a nerve. | 06-10-2010 |
