  • Publication number: 20050288550
    Abstract: This invention relates generally to lung access devices and methods of using the devices to gain access to the interior of a lung or to the mediastinal space around the lung. In particular, the invention relates to auxiliary access devices and tools for use with conventional bronchoscopes or other endoscopes to enable the delivery of more and larger devices to a target site than is currently possible through a typical endoscope or bronchoscope.

  • Publication number: 20050272969
    Abstract: An intravascular support device includes a support or reshaper wire, a proximal anchor and a distal anchor. The support wire engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed. The anchors and support wire are designed such that the vessel in which the support is placed remains open and can be accessed by other devices if necessary. The device provides a minimal metal surface area to blood flowing within the vessel to limit the creation of thrombosis. The anchors can be locked in place to secure the support within the vessel.

  • Publication number: 20050261704
    Abstract: An assembly for effecting the condition of a mitral valve of a heart includes a mitral valve therapy device, a guide wire, and a guide tube. The mitral valve therapy device is configured to reshape the mitral valve annulus of the heart when placed within the coronary sinus adjacent the mitral valve annulus. The guide wire is configured to be fed into the coronary sinus of the heart adjacent the mitral valve annulus. The guide tube has a distal end, a proximal end, and a lumen extending between the distal end and the proximal end. The guide tube further includes a side port, intermediate the distal and proximal ends which communicates with the lumen. This permits the guide tube to be slidingly received on the guide wire with the guide wire extending from the distal end, through the lumen, and out the side port. In use, the guide tube is slid along the guide wire into the coronary sinus.

  • Publication number: 20050216077
    Abstract: A device affects the mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and anchored to the coronary sinus of the heart adjacent the mitral valve annulus within the heart and a second anchor configured to be positioned within the coronary sinus of the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart. The second anchor, when deployed, anchors against distal movement and is moveable in a proximal direction. The device further includes a connecting member having a fixed length permanently attached to the first and second anchors. As a result, when the first and second anchors are within the coronary sinus with the first anchor anchored in the coronary sinus, the second anchor may be displaced proximally to affect the geometry of the mitral valve annulus and released to maintain the effect on the mitral valve geometry.

  • Publication number: 20050065598
    Abstract: A mitral valve therapy device effects the condition of a mitral valve annulus of a heart. The device includes an elongated member dimensioned to be placed in the coronary sinus of the heart adjacent the mitral valve annulus. The elongated member is flexible when placed in the heart in a first orientation to position the device in the coronary sinus adjacent the mitral valve annulus and relatively inflexible when rotated into a second orientation after the device is positioned in the coronary sinus adjacent to the mitral valve annulus to substantially straighten and increase the radius of curvature of the mitral valve annulus.

  • Publication number: 20040249403
    Abstract: This invention is a surgical device for producing a generally circular, interlamellar pathway within the corneal stroma of the eye. The device is made up of three major components: a vacuum centering guide having an inner bore which fits at one end against the front of the eye, a barrel which fits within the inner bore of the centering guide and to which is attached the third major component, a generally circular dissecting ring. The dissecting ring is shaped in such way that when an eye surgeon twists the barrel to which the ring is attached, the ring moves through the interlamellar space in the stroma producing the desired channel or pathway. The centering guide may optionally include a ring having one or more pins which firmly engage the cornea's epiphilium. The constituent parts of the surgical device, particularly the dissecting ring, also form a part of this invention.

  • Publication number: 20040133240
    Abstract: A system for treating cardiac valve dysfunction includes a lead with electrodes in electrical communication with muscle tissue proximate to a cardiac valve to be treated. Electrical energy is delivered to the lead electrodes to stimulate contraction of the muscle tissue and thereby constrict the cardiac valve. The lead may be received within a blood vessel in the patient. Detection circuitry may detect a physiological signal in the patient for controlling the timing of delivery of electrical energy. The lead may have one or more undulations. The lead may also be combined with a prosthesis to provide a combined electromechanical cardiac valve therapy. The lead can be attached to the prosthesis or formed integrally with the prosthesis. One embodiment implanted in the coronary sinus is used to treat dilated cardiomyopathy of the mitral valve.
