20100228280 | METHODS AND DEVICES FOR TREATMENT OF LUMENAL SYSTEMS - The invention provides a variety of catheters and methods for using such catheters. An exemplary catheter includes an elongate body having a proximal end a distal end. The elongate body defines a longitudinal axis of the catheter. The exemplary catheter further includes at least one inflatable member disposed on the elongate body proximate the distal end of the elongate body. The interior of the inflatable member is in fluid communication with an inflation lumen in the elongate body. The exemplary catheter also includes a first filter adapted and configured to capture emboli in a patient's bloodstream as the bloodstream passes through the first filter along a first direction. The exemplary catheter further includes a second filter adapted and configured to capture emboli in a patient's bloodstream as the bloodstream passes through the second filter along a second direction, wherein the second direction is generally opposite to the first direction. | 09-09-2010 |
20110251487 | Apparatus and Methods for Intravascular Ultrasound Imaging and for Crossing Severe Vascular Occlusions - An intravascular ultrasound catheter system is provided and enables a simplified, economical technique for ultrasound visualization of a blood vessel. The catheter may include a park ablation system for crossing chronic total occlusions and severe stenoses. The catheter is advanceable and is oriented entirely under manual control of the clinician and the application of radiofrequency energy for spark erosion of the stenosis also is controlled manually by the clinician. The system enables the clinician to observe an ultrasound image sufficiently to determine where to orient the ablation electrode so as to reduce the risk of dissection or perforation of the blood vessel. The ultrasound image is generated in response to manual rotation of the catheter and the ablation spark is generated only when the physician is satisfied as to the orientation of the electrode within the vessel. | 10-13-2011 |

20140188108 | Energy Assisted Tissue Piercing Device and Method of Use Thereof - An energy assisted tissue piercing device that enables a tissue piercing wire to puncture heart tissue percutaneouly. The energy assisted tissue piercing device includes an outer delivery catheter, an inner tissue piercing wire, and an energy source. The inner tissue piercing wire is disposed longitudinally through the lumen of the outer delivery catheter during delivery. The inner needle has a flexible portion that allows the wire to bend when it is free from the constraint of the outer delivery catheter. The inner tissue piercing wire is conductive and connected to an energy source and the piercing of the heart tissue is done with the aid of the energy from the energy source. | 07-03-2014 |
20140277054 | DEVICES, SYSTEMS, AND METHODS FOR PERCUTANEOUS TRANS-SEPTAL PUNCTURE - The present teachings provide devices for puncturing the atrial septum percutaneously. Specifically, one aspect of the present teachings provides a trans-septal puncturing device comprising one or more of a locating element, a stabilizing element, a puncturing element, a safety element, and optionally a monitoring element, each of which is disposed in a lumen of a sheath. The locating element and the stabilizing element locate a desired puncture site and stabilize the trans-septal puncturing device at or near the site. The puncturing element of the trans-septal puncturing device has a limited puncturing distance due in certain instances to the safety element. The present teachings provide methods of using such device for percutaneously locating a fossa ovalis, stabilizing such device at the fossa ovalis, and piercing tissue across the fossa ovalis. | 09-18-2014 |
