| 20080287862 | Drive systems and methods of use - Drive systems and methods of use are disclosed herein for performing medical procedures on a patient. The drive systems include various handle types and triggers for controlling catheters and end effectors. The various handle types include a flexible handle and ambidextrous handles that can alter the handedness of the handle for particularized use. The handles drive articulation sections of the catheter and end effectors with various degrees of freedom, and include locks for holding the catheter and/or end effector in place. The catheter systems include structures for allowing degrees of freedom, such as notches, mechanical interlocks, and articulation joints. In addition, the catheters articulate via cables or fluids. | 11-20-2008 |
| 20080287988 | Tissue aperture securing and sealing apparatuses and related methods of use - Embodiments of the invention may be directed to apparatuses for securing and sealing apertures in tissue and related methods of use. | 11-20-2008 |
| 20090182200 | MEDICAL DEVICE - Apparatuses of the type broadly applicable to numerous medical applications in which it is desirable to insert one or more steerable or non-steerable catheters or similar devices into a working channel of an associated device, such as an endoscope, catheter, etc., or passageway of a patient, are disclosed. The apparatuses may include catheters having a dedicated guide wire channel and one or more of the following: viewing capabilities, a working channel, and auxiliary channels, such as insufflation/irrigation channels. The catheters may include a guide wire channel that is configured to provide the catheter or other device with rapid exchange capabilities. | 07-16-2009 |
| 20090192518 | APPARATUS AND METHOD FOR LOADING AND DELIVERING A STENT HAVING IMPROVED HANDLES TO CONTROL RELATIVE CATHETER COMPONENT MOVEMENT - A catheter handle assembly for delivering stent includes a proximal handle attached to an axially elongated inner member with a distal tip and an intermediate handle attached to an axially elongated intermediate tube with a stent basket at its end. The intermediate tube overlies at least a portion of the inner member. A distal handle is attached to an axially elongated external member overlying at least a portion of the intermediate tube are disclosed. | 07-30-2009 |
| 20090287188 | STEERING SYSTEM WITH LOCKING MECHANISM - A steerable device, such as a steerable catheter, may include a control handle and an insertion shaft extending outwardly therefrom. In use, the insertion shaft is navigated to an area of interest for examination and/or treatment thereof. The steerable device may include a steering system that controls the deflection angle of the distal end of the insertion shaft in two or more non-planar directions for navigating the insertion shaft to the area of interest. The steering system may also include a locking mechanism for arresting or partially arresting the movement of the distal end of the insertion shaft in a first direction independent of arresting or partially arresting the movement of the distal end in a second non-planar direction. | 11-19-2009 |
| 20100114116 | Medical Device Control System - A control system for allowing a physician to control the orientation of a medical device or a medical instrument in a variety of directions with one hand. An actuator selectively tensions one or more control cables having ends secured at or adjacent a distal tip of the medical device in order to bend the distal tip in a desired direction. In one embodiment, a physician can adjust the movement of the distal tip in a desired direction without affecting the orientation of the medical device in other directions. | 05-06-2010 |
| 20110077621 | LOCKING MECHANISM FOR A MEDICAL DEVICE - A locking mechanism for a medical device to selective lock a first elongate member from longitudinal movement relative to a second elongate member of the medical device. The locking mechanism includes a flexible tubular member disposed in a bore of a handle assembly of the medical device, and an actuator, such as a cam member having a cam or eccentric surface. Pivotable movement of the actuator from a first position to a second position compresses or deforms the flexible tubular member against the first elongate member to lock the first elongate member from longitudinal movement relative to the handle assembly. | 03-31-2011 |
| 20110224575 | Needle with Helical Grooves Converting Axial Movement to Rotational Movement - A device for penetrating tissues within a living body, comprises a shaft extending from a proximal end which, in an operative position, remains outside the body to a distal end which, in the operative position, is within a living body, the shaft comprising a channel extending therethrough from the proximal end to an opening at the distal end. The device also comprises a needle extending within the channel and comprising a tissue penetrating tip. A portion of an outer surface of the needle includes a first structure wrapping therearound and configured to mate with a second structure formed on a corresponding portion of an inner wall of the shaft. The first and second structures mate with one another so that, as the needle is urged axially through the channel, the mating causes the needle to rotate about an axis of the channel. | 09-15-2011 |
