  • Publication number: 20190374270
    Abstract: Apparatus and methods are provided for the approximation of two bones, the apparatus including a first anchor that is rotationally driven into a first bone by a second bone anchor, which receives driving torque from a driver tool. After the first anchor is secured in the first bone, the second anchor is disengaged from the first anchor but remains connected to the first anchor by a flexible link of a designed length. The second bone anchor is secured in the second bone and has provisions to be lengthened or shortened to adjust the overall length of the implant, thereby adjusting the approximation between the two bones.

  • Publication number: 20070169877
    Abstract: Apparatus and methods are provided for substantially continuously forming thin-walled sleeves that may be incorporated into tubular devices sized for introduction into a patient. In one embodiment, a pair of sheets including coated surfaces oriented towards one another are directed through a cutting apparatus to cut the sheets into multiple pairs of strips. The pairs of strips are bonded together to create a plurality of sleeves having lumens defined by the coated surfaces. In another embodiment, a sheet having a coated surface is fed through a cutting tool to separate the sheet into a plurality of strips, and the strips are formed into sleeves, e.g., by feeding the strips through a die or mandrel using a substantially continuous process. Optionally, the sleeves may be subsequently cut into individual tubular devices and/or further processed, e.g., by providing one or more layers around the sleeves to create catheters, sheaths, or other apparatus.

    Abstract: Splittable tubular devices and methods for making them are provided. In one embodiment, a tubular device includes a proximal end, a distal end sized for introduction into a body lumen, and a lumen extending between the proximal and distal ends. The tubular device includes an outer tubular layer defining a circumference; and a reinforcing layer bonded to the outer tubular layer, the reinforcing layer including a circumferential interruption. To make a tubular device, an elongate tubular reinforcing structure may be folded into itself to define first and second longitudinal edges, and rolled until the longitudinal edges are disposed adjacent one another.

  • Publication number: 20070083187
    Abstract: Apparatus, systems, and methods are provided for delivering stem cells or other agents to cardiac tissue surrounding a cardiac vessel or to tissue adjacent other body lumens. The apparatus includes an expandable member and a source of one or more agents communicating with a lumen extending between proximal and distal ends of the apparatus. The distal end of the apparatus is advanced through one or more body lumens until the distal end is disposed within or adjacent the target body lumen. The target body lumen is sealed, e.g., by expanding the expandable member, thereby isolating the target body lumen. One or more agents are delivered into the target body lumen with sufficient pressure to extravasate the one or more agents into tissue surrounding the target body lumen.

  • Publication number: 20070083217
    Abstract: An apparatus for imaging a body structure within a body cavity includes a catheter including proximal and distal ends, an imaging element on the distal end, and an extension extending distally from the distal end for contacting a surface of a body cavity into which the catheter is introduced. The extension has a length to maintain the optical imaging element away from the surface. Optionally, a transparent member, e.g., an expandable balloon, may be attached to the distal end of the tubular member and the extension to isolate the imaging element from contact with fluid within the body cavity. During use, the catheter is inserted into a chamber of a beating heart, and the extension and/or balloon is placed against the wall of the chamber. Sufficient force is applied to stabilize the imaging element relative to the wall while the heart is beating.

  • Publication number: 20070074805
    Abstract: A method for making a tubular device includes coating a first surface of a thin sheet, rolling the sheet such that side edges of the sheet are disposed adjacent one another with the coating disposed inwardly, creating a longitudinal seam along the side edges to create a sleeve, and attaching a tubular structure around the sleeve. In another embodiment, the method includes coating a first surface of a thin sheet, wrapping the sheet partially around a mandrel with the coating disposed inwardly, positioning a slotted tube around the sheet and mandrel, attaching the tube to the thin, and trimming any excess material of the sheet.

  • Publication number: 20070016130
    Abstract: Apparatus and methods are provided for accessing a body lumen within a patient's body. Generally, the apparatus includes a tubular member including proximal and distal ends, a steering element extending between the proximal and distal ends, and an actuator for directing the distal end between a relaxed configuration and a complex curved configuration. In the relaxed configuration, the distal end may assume a straight or curved shape. In the complex curved configuration, the distal end may assume a curvilinear shape. In one embodiment, the complex curved configuration may include a first curved portion defining an arc within a plane, and a second portion that extends out of the plane. An embodiment with a left hand rule configuration may be introduced into the right atrium of a heart from a superior approach, and the complex curved configuration may facilitate accessing the coronary sinus.

    Abstract: Apparatus and methods are provided for providing access to a body lumen. The apparatus includes a tubular member including a proximal end, a distal end sized for insertion into a body lumen, and a lumen extending therebetween. A pushable stiffening member extends from the distal end of the tubular member. An expandable sheath extends along at least a portion of the stiffening member, the sheath being expandable from a contracted condition to facilitate insertion into a body lumen, and an enlarged condition wherein the sheath at least partially defines a lumen communicating with the tubular member lumen. A distal portion of the sheath is steerable, e.g., using a pull wire disposed within a lumen of the sheath or within the stiffening member. In addition or alternatively, the stiffening member may be biased to a predetermined shape to facilitate introduction.

  • Publication number: 20060084839
    Abstract: Apparatus and methods for locating morphological features within a body cavity using a catheter including proximal and distal ends, a transparent balloon carried on the distal end, and an optical imaging assembly carried on the distal end for imaging through the balloon. The balloon includes a channel extending therethrough to a lumen extending through the catheter. A guidewire or other localization member is received in the lumen that is extendable through the channel. During use, the catheter is inserted into a right atrium of a heart, and the balloon is expanded and placed against the wall of the heart to locate the coronary sinus. Sufficient force is applied to clear blood between the surface and the wall and clear the field of view of the imaging assembly. The catheter is manipulated to locate the coronary sinus, whereupon the localization member is advanced into the coronary sinus.
