  • Publication number: 20080086155
    Abstract: Apparatus and methods for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

  • Publication number: 20070129720
    Abstract: Methods and apparatus are provided for non-continuous circumferential treatment of a body lumen. Apparatus may be positioned within a body lumen of a patient and may deliver energy at a first lengthwise and angular position to create a less-than-full circumferential treatment zone at the first position. The apparatus also may deliver energy at one or more additional lengthwise and angular positions within the body lumen to create less-than-full circumferential treatment zone(s) at the one or more additional positions that are offset lengthwise and angularly from the first treatment zone. Superimposition of the first treatment zone and the one or more additional treatment zones defines a non-continuous circumferential treatment zone without formation of a continuous circumferential lesion. Various embodiments of methods and apparatus for achieving such non-continuous circumferential treatment are provided.

  • Publication number: 20060178560
    Abstract: Systems, devices and methods for endoscopic procedures are provided involving accessing and manipulating tissues beyond the capabilities of traditional endoscopic instruments. Embodiments of the systems include an elongated main body which has one or more independently shape-lockable sections and a variety of instruments which are either built in to the main body or advanceable through lumens which extend through the main body. Such instruments may include scopes, suction instruments, aspiration instruments, tool arms, plicators, needles, graspers, and cutters, to name a few. The ability to steer and shapelock specific sections of the main body enables access to target locations which are typically challenging to reach and provides a stabilized platform to perform a desired procedure at the target location.

  • Publication number: 20060155330
    Abstract: Apparatus (10) is provided for sealing a vascular puncture tract by forming the autologous plug within the puncture tract, and extruding that plug into the puncture tract. The apparatus of the present invention forms an autologous blood plug by drawing blood into the apparatus from a vessel, mixing a blood congealing agent with the drawn blood, and ejecting a plug formed from the clotted blood within the puncture tract. Also provided are various closure elements (22) to isolate the drawn blood from the vessel during mixture with the blood congealing agent, and to facilitate placement of the apparatus relative to the vessel.

  • Publication number: 20060127595
    Abstract: The present invention provides methods and apparatus for selectively patterning surfaces using radical species generated with a photocatalyst. The photocatalyst may comprise a photocatalytic semiconductor or a photosensitizer. The radical species are brought into contact with an oxidizable coating disposed on the surface, thereby locally oxidizing and selectively patterning the surface. The photocatalyst is preferably disposed on a delivery device, such as a stamp, mask, or scanning probe, that is brought into close proximity or contact with the coated surface. The photocatalyst is then excited in a manner capable of generating radical species, for example, oxygen-containing radical species, in appropriate media. It is expected that these radical species will be transferred to the coated surface along a substantially shortest distance path, thereby locally oxidizing and patterning the surface.

  • Publication number: 20060116756
    Abstract: A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

  • Publication number: 20060100665
    Abstract: Apparatus is provided for sealing a puncture in a blood vessel using at least one device that applies an internal compressive force upon a distal surface of the vessel. The devices preferably are deployable distal of the distal surface of the vessel, then retracted proximally to provide the internal compressive force, e.g., to promote coagulation and facilitate sealing of the puncture. Additionally, the devices of the present invention optionally may be used in combination with known techniques that provide an external compressive force upon an exterior surface of a patient's skin to expedite sealing of the puncture.

The apparatus includes a replacement valve and an expandable anchor configured for endovascular delivery to a vicinity of the patient's heart valve. In some embodiments, the replacement valve is adapted to wrap about the anchor, for example, by everting during endovascular deployment. In some embodiments, the replacement valve is not connected to expandable portions of the anchor. In some embodiments, the anchor is configured for active foreshortening during endovascular deployment. In some embodiments, the anchor includes expandable lip and skirt regions for engaging the patient's heart valve during deployment. In some embodiments, the anchor comprises a braid fabricated from a single strand of wire. In some embodiments, the apparatus includes a lock configured to maintain anchor expansion. The invention also includes methods for endovascularly replacing a patient's heart valve.

  • Publication number: 20050277981
    Abstract: Apparatus and methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

  • Publication number: 20050251208
    Abstract: Linear anchors for anchoring to tissue are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor, which may be a ribbon, flattened wire, etc., is adapted to be delivered in an elongate straightened configuration through or against the tissue and then compressed along a longitudinal direction such that a tissue plication may be cinched between anchors. The elongate anchor defines a plurality of holes along its length in any number of patterns. A length of suture is routed through these holes such that tensioning the suture urges the elongate anchor to compress into its expanded anchoring configuration. A locking mechanism facilitates the cinching of the anchor against the tissue surface.
