Abstract: A kit for implanting a woven retention device into bone includes a woven retention device, a delivery tube, and a push rod. The woven retention device includes a distal end that is tapered to a distal tip, a proximal end for receiving a fastener, and a sleeve body between the distal and proximal ends. The delivery tube includes distal and proximal openings, and a compression portion over at least a distal end of the delivery tube. The push rod can be slideably received within the delivery tube and has a distal end for pushing the woven retention device through the distal opening of the delivery tube.

Abstract: A system for preparing and inserting a woven retention device into bone is provided. The system includes a woven retention device having a distal end, a proximal end for receiving a fastener, and a sleeve body between the distal and proximal ends. A longitudinal axis extends between the distal and proximal ends. The system also includes a measuring device surrounding at least a portion of the woven retention device and defining a cutting position at which the woven retention device is to be cut for insertion into a hole in the bone. The measuring device measures a distance from the distal end of the woven retention device to the cutting position. The woven retention device is movable relative to a least a portion of the measuring device that defines the cutting position such that the woven retention device can be cut to a desired size.

Abstract: A method of inserting a woven retention device into a bone hole includes providing a woven retention device with a tapered distal end and a proximal end to receive a fastener, providing a delivery tube with distal and proximal openings, and providing a push rod to push the woven retention device through the distal opening of the delivery tube. The delivery tube includes a compression portion over at least a distal end of the delivery tube. The method also includes positioning the distal opening of the delivery tube near an opening of the bone hole and advancing the woven retention device through the compression portion of the distal opening of the delivery tube and into the bone hole by pushing on an interior of the tapered distal end of the woven retention device using the distal end of the push rod.

Abstract: An endo-surgical device, system and method are provided. The endo-surgical device includes a flared prow that limits the displacement and rotation of the cannula to keep the knife away from tissues that are not intended to be cut. The endo-surgical tool can be utilized as part of a system for performing an endo-surgical procedure.

Abstract: A bone cutting and injecting device for cutting maxillary bone and injecting a filler through the maxillary bone under a subantral membrane to separate the subantral membrane from the maxillary bone and fill the space formed therebetween. The device includes a hollow tubular element having a diameter sized to be inserted into a pilot hole in the maxillary bone, a piston longitudinally displaceable within the hollow tubular element, and a cutter mounted to the piston and operably disposed adjacent the distal end of the hollow tubular element. A fluid path is defined through the hollow tubular element for guiding the filler, and the cutter is configured to redirect the filler in a transverse or radial direction relative to the longitudinal axis of the tubular element.

Abstract: Tooling and methodologies for separation and dissection of the subantral membrane from the floor of the maxillary sinus, and for packing bone and bone substitutes under the subantral membrane. The tooling and associated methodology employ a handle and one or more support structures extending therefrom. A thin member extends from the distal end of the support structure(s). The thin member has a first peripheral region disposed opposite a second peripheral region. The first peripheral region is joined to or integrally formed with the distal end of the support structure(s). The second peripheral region defines a thin blade-like section for dissecting the subantral membrane from the floor of the maxillary sinus. In the preferred embodiment, the blade-like section is angled downward away from the distal support structure, which aids in positioning the blade-like section on the floor of the maxillary sinus.

Abstract: A device includes a tubular element, and a cutter spring-biased relative to the tubular element. In an unloaded configuration the cutter is displaced relative to the tubular element by a displacement distance, and when the cutter is in a loaded configuration the displacement distance is reduced. A first structure is longitudinally fixed relative to the cutter and rotationally engaged relative to the tubular element. A length of the first structure extends proximally in the unloaded configuration. A second structure is longitudinally displaceable relative to the first structure. In the loaded configuration, a driver engages and rotates both the first and second structures, and thus the tubular element and cutter together. Once the cutter breaks through the bone, the cutter spring-biased into the unloaded configuration, resulting in disengagement of the first structure from the driver to prevent rotation of either the tubular element or the cutter.

Abstract: A wheelchair has a frame which includes a right fore member and a left fore member, and a footrest between them. The footrest includes a right supporting arm extending rearwardly from the right fore member, a left supporting arm extending rearwardly from the left fore member, and a panel upon which may rest a users feet and which pivotably attaches to the right supporting arm at a rearward portion thereof and pivotably attaches to the left supporting arm at a rearward portion thereof. The panel is pivotable upwardly and rearwardly from a first position in which it is generally horizontally oriented for supporting the user's feet to a second position behind the user's feet whereby to allow the user to stand unencumbered by the panel.
