摘要:
A medical device and method for the treatment of a sinus opening includes a handle, a guide catheter, a guide wire, a balloon catheter, a guide wire movement mechanism and a balloon catheter movement mechanism. The handle has proximal and distal ends and a longitudinal axis along the length of the handle. The guide catheter is attached to the distal end of the handle and has a catheter lumen. The guide wire and balloon catheter are both disposed at least partially in the handle and catheter lumen. The guide wire movement mechanism and the balloon catheter movement mechanism are both operatively disposed on the handle. In addition, the guide wire movement mechanism is configured for advancement and retraction of the guide wire through the handle and catheter lumen by user operation of the guide wire movement mechanism. Moreover, the guide wire movement mechanism includes an integrated guide wire locking and rotation mechanism configured for rotation of the guide wire and for securely locking and unlocking the guide wire to the guide wire movement mechanism. Furthermore, the balloon catheter movement mechanism is configured for advancement and retraction of the balloon catheter through the handle and catheter lumen by user operation of the balloon catheter movement mechanism.

A medical device for the treatment of a sinus opening includes a handle, a grooming sheath, a rail, a guide wire, a balloon catheter and a balloon catheter movement mechanism. A method for treating a sinus opening includes inserting a medical device for the treatment of a sinus opening partially into a patient's anatomy, positioning a guide wire operatively extending from a rail of the medical device into a sinus opening of the patient, advancing a balloon catheter from an annular lumen of the medical device and along both the rail of the medical device and the guide wire with a balloon catheter movement mechanism, and inflating the balloon catheter.

An irrigation catheter for the treatment of the sinus anatomy is described. The catheter comprises a proximal portion, a rigid middle portion, and a flexible distal portion. The flexible distal portion comprises an irrigation tip and the proximal portion has a stiffness that is intermediate the stiffness of the rigid middle portion and the flexible distal portion. The irrigation tip has a tip opening and one or more radially facing openings. A method for irrigating or suctioning the sinus anatomy includes inserting an irrigation catheter into a patient's anatomy and irrigating or suctioning a target space.

A medical device, and a system and packaged kit containing the medical device for the treatment of a sinus opening is described. The medical device comprises a proximal end, a distal end, and a shaft system having an inflation lumen and an irrigation lumen the proximal and. The shaft system has a proximal shaft section and a distal shaft section. An inflatable balloon is attached to the distal shaft section in a position that is proximal to said distal end. The irrigation tip is distal to the balloon on the distal shaft section and has a tip opening and one or more radially facing openings. A method for treating a sinus opening includes inserting a system that includes the medical device, a sinus guide catheter and a sinus guide element into a patient's anatomy, dilating the sinus opening and irrigating a target in the nasal anatomy.

The invention is an endoscopic method for viewing a target portion of a patient's anatomy with access through the oral or nasal cavity. The method includes adjusting a variable direction of view endoscope to a direction of view of between about 0 degrees and 20 degrees relative to a longitudinal axis of the endoscope and a shaft orientation pointing toward the target portion of the patient's anatomy. The endoscope is then introduced straight into the oral or nasal cavity of a patient until the endoscope is positioned in the back of the cavity. The direction of view is adjusted to view the target portion of the patient's anatomy.
摘要:
The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. The tissue structures can be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment. In one aspect, a structure is deployed in a gutter region of the valve annulus to modify the shape of the valve.

摘要:
The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.
摘要:
Devices, systems and methods are provided for tissue approximation and repair at treatment sites, particularly in those procedures requiring minimally-invasive or endovascular access to remote tissue locations. Fixation devices are provided to fix tissue in approximation with the use of distal elements. In some embodiments, the fixation devices have at least two distal elements and an actuatable feature wherein actuation of the feature varies a dimension of the at least two distal elements. In other embodiments, the fixation devices have at least two pairs of distal elements wherein the pairs of distal elements are moveable to engage tissue between opposed pairs of distal elements. Systems are also provided having fixation devices and accessories.
