20080287989 | Tissue holding implants - Tissue holding implants which enable two or more layers of tissue to be held in approximation for an extended period. One and two-piece implants are described, made from materials that are biocompatible, and may also be biodegradable. Some embodiments include a portion which is deformed to capture the tissues to be held, and others are made from a super-elastic or shape memory material and hold the tissues in approximation when the implant is reverted to a known preformed shape. | 11-20-2008 |
20090048683 | Tissue positioning device - A tissue positioning device comprising a biocompatible member having a size and shape suitable for placement within a space adjacent to a tissue to be positioned and which acts to maintain the tissue in a desired position. The member may be a rigid or flexible spacer having a defined shape, or a bladder capable of receiving and being at least partially expanded by a filler material. The device can made from a variety of materials or a composite of materials as needed, and may include one or more attachment means by which it can be secured to nearby tissues such that it is maintained in a desired spatial location. The filler material can be any of a number of substances, including liquids, gases, a curable liquid such as bone cement or urethane foam, or a spring. | 02-19-2009 |
20090125071 | SHAPE-CHANGING ANATOMICAL ANCHOR - A shape-changing anatomical anchor includes an activation means arranged to convert the anchor from a de-activated state to an activated state, and one or more members which extend away from the activation means and thereby change the shape of the anchor when the anchor is activated. The anchor is installed within bone and/or soft tissue when de-activated; when activated, the shape change acts to increase the force with which the anchor is retained within the tissue in which it is installed. Both piloted and non-piloted versions are described. | 05-14-2009 |
20090254102 | DELIVERY MECHANISM FOR TISSUE HOLDING IMPLANTS - A delivery mechanism for delivering tissue holding implants through tissues to be held in approximation includes a shaft having a tip at its distal end, and which is loaded with one or more implants. A wire channel which contains a driving wire is also located within the shaft. When the mechanism is actuated, the driving wire exhibits a proportional longitudinal displacement in the wire channel, such that the wire engages an implant, conveys it along the shaft's longitudinal axis towards the tip, and forces it through the tip. The implants are oriented such that they lie along or nearly along the shaft's longitudinal axis when being conveyed along the axis. The mechanism may optionally include an opposing jaw arranged such that, when actuated, the distal end of the jaw is moved towards the tip, such that tissues placed between the jaw and tip are pinned between them. | 10-08-2009 |
