20110264074 | FIVE DEGREE OF FREEDOM ULTRASOUND CATHETER AND CATHETER CONTROL HANDLE - Catheter ultrasound systems including a sheath, a handle, a sheath lumen, and an ultrasound catheter disposed within the lumen of the sheath with ultrasound elements capable of visualizing anatomical regions. The handle allowing the ultrasound catheter to rotate with respect to the sheath using a rotation adjustment knob within the handle or alternatively an separate manipulation handle attached to the proximal end of the ultrasound catheter. The sheath, ultrasound catheter, or both may also include one or more electrodes or other location sensor for both orienting the ultrasound element as well as for diagnostic purposes. | 10-27-2011 |
20110288392 | Kit for Non-Invasive Electrophysiology Procedures and Method of its Use - An electrophysiology catheter for use with a steerable introducer sheath includes a flexible catheter body having a proximal end and a distal end and at least one hollow elongate tip electrode disposed at the distal end of the catheter body. The hollow elongate tip electrode includes a sidewall having at least one elongate gap that provides flexibility allowing the tip electrode to bend relative to a longitudinal axis of the catheter body. The catheter body is an independent, non-steerable structure, and can be moved via movement of the steerable introducer through which it is introduced into a patient. | 11-24-2011 |
20120010490 | Medical devices having flexible electrodes mounted thereon - Medical devices and systems comprising medical devices are provided. The kit includes a catheter-introducer comprising a shaft having a major lumen sized to receive a second medical device and an electrode mounted thereon and a catheter comprising an elongate body and at least two flexible electrode segments on the distal end. The shaft includes an inner liner and outer layer. The system comprises a first medical device having a shaft and an electroanatomical system imaging element mounted thereon and a second medical device having an elongate body and at least two flexible electrodes mounted on the distal end. The shaft has a major lumen sized to receive the second medical device. The system further comprises an electroanatomical navigation system configured to receive signals from the electroanatomical system imaging element and to determine a position of the electroanatomical system imaging element and/or monitor electrophysiological data. | 01-12-2012 |
20120130218 | Medical devices having an electroanatomical system imaging element mounted thereon - Medical devices and systems comprising medical devices are provided. The device comprises a shaft having a major lumen sized to receive a second medical device and an electroanatomical system imaging element mounted thereon.

The shaft has a major lumen sized to receive another device. The system further comprises an electroanatomical navigation system configured to receive signals from the electroanatomical system imaging element and to determine a position of the electroanatomical system imaging element and/or monitor electrophysiological data. | 05-24-2012 |
20120172840 | Hydrophobic catheter and composition - In various embodiments, a surgical catheter is provided. The catheter may comprise one or more hydrophobic barrier layers made from an ethylene-pertfluoroethylenepropylene (“EFEP”) copolymer. Additionally, the catheter may comprise another polymer layer made from a reactive polar polymer. In at least one embodiment, the reactive polar polymer may be a modified-poly(ether block amide) (“PEBA”) copolymer, such as an amine-terminated PEBA. Moreover, in various embodiments, a composition is provided that may comprise a reactive polar polymer bonded to an EFEP copolymer. | 07-05-2012 |
20120221001 | Magnetically guided catheters - A magnetically-guided catheter | 08-30-2012 |
20120283552 | SENSOR ASSEMBLY TETHERED WITHIN CATHETER WALL - A distal tip assembly for an elongate medical device having an axis comprises a shaft having a proximal end portion, a distal end portion, a wall, and a central lumen extending axially between said proximal end portion and said distal end portion. The distal tip assembly further comprises a position sensor disposed in an outer sleeve such that the sensor can shift relative to the sleeve. The sleeve is disposed at least in part in the wall and is substantially fixed thereto. | 11-08-2012 |
20130172786 | CATHETER WITH ATRAUMATIC TIP - A medical device is provided comprising a shaft comprising a first segment and a second segment. The first segment is configured to buckle upon application of a first critical force. The second segment includes an outer surface and an inner surface and is configured to buckle upon application of a second critical force. The second critical force is lower than the first critical force. The medical device further comprises a coil disposed radially inwardly of the inner surface of the second segment. | 07-04-2013 |
20130338467 | Electrode catheter device with indifferent electrode for direct current tissue therapies - An electrode catheter device with indifferent electrode for direct current tissue therapies is disclosed. An example of the catheter device has a flexible tubing with at least one ablation electrode. The catheter device also may also be used with a sheath for introducing the flexible tubing inside a patient's body. An indifferent electrode on the sheath can provide a ground for a direct current (DC) pulse to deliver electrical energy and create an electrical field adjacent a tissue. Various other embodiments are also disclosed. | 12-19-2013 |
