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.
Core Innovation
The invention describes an orthopedic kit for implanting a woven retention device into bone. The kit includes a woven retention device having a distal end tapered to a distal tip, a proximal end configured to receive a fastener, and a sleeve body between the distal and proximal ends. The kit further includes a delivery tube having a distal opening and a proximal opening.
The delivery tube has a compression portion over at least a distal end of the delivery tube. The compression portion comprises a narrowed region at or near the distal opening of the delivery tube, where the narrowed region has an inner diameter less than a first outer diameter of the sleeve body. The push rod is configured to be slideably received within the delivery tube, with a distal end configured to push the woven retention device through the distal opening.
The kit also relates to measurement and cutting arrangements for determining a desired length of the woven retention device to be inserted into the bone hole. A measuring device includes indicia arranged to indicate a distance from the distal tip of the woven retention device to a reference point at which the woven retention device is able to be cut. The indicia are arranged on the package in a predetermined relationship to the woven retention device, or are provided on a slidable measuring surface with a cutting indicator that indicates a location on the woven retention device where cutting is to be performed.
Claims Coverage
The document provides three independent claims (clm-00001, clm-00023, clm-00024). Across the independent claims, the coverage focuses on the kit structure for implanting a woven retention device using a delivery tube with a compression portion and a slideable push rod, and on measuring/cutting coordination via indicia and package features.
Woven retention device with sleeve body and tapered distal tip
A woven retention device having a distal end that is tapered to a distal tip, a proximal end configured to receive a fastener, and a sleeve body between the distal and proximal ends.
Delivery tube with distal/proximal openings and compression portion
A delivery tube including a distal opening and a proximal opening, the delivery tube having a compression portion over at least a distal end of the delivery tube.
Compression narrowed region defined by inner diameter less than sleeve outer diameter
The compression portion comprises a narrowed region at or near the distal opening of the delivery tube, the narrowed region having an inner diameter that is less than a first outer diameter of the sleeve body.
Slideable push rod configured to advance device through distal opening
A push rod configured to be slideably received within the delivery tube and having a distal end configured to push the woven retention device through the distal opening of the delivery tube.
Measuring device with indicia using distance from distal tip to cut reference point
A measuring device arranged to measure a desired length of the woven retention device to be inserted into the bone hole, the measuring device comprising indicia arranged to indicate a distance from the distal tip of the woven retention device to a reference point, the reference point being a point at which the woven retention device is able to be cut to achieve the desired length.
Package with predetermined relationship of indicia to mounted woven retention device
A package containing the woven retention device, wherein the indicia are arranged on the package, and the woven retention device is mounted on the package in a predetermined relationship relative to the indicia.
Package with slidable measuring surface and fixed cutting indicator
A package comprising a mounting surface to which the woven retention device is mounted, a measuring surface including at least one set of measuring indicia, the measuring surface being slidable relative to the mounting surface, and a cutting indicator fixed to the measuring surface, the cutting indicator being configured to indicate a location on the woven retention device where cutting is to be performed.
The independent claims collectively define an implanting kit with a woven retention device, a delivery tube having a compression portion including a narrowed region with an inner diameter less than the sleeve body outer diameter, and a slideable push rod to push the woven retention device through the distal opening. Two independent claims further add coordinated measurement and cutting structures using measuring devices with indicia and package arrangements, including predetermined indicia relationships and a slidable measuring surface with a fixed cutting indicator.
