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 |
20090099577 | Implant System - A system and method for inserting an implant into soft tissue. The system may include an elongate arm having an implant at a first end of the elongate arm and an actuator at a second end of the elongate arm. The implants may be contained in a cartridge assembly. Methods of inserting an implant may be used during nasal septum reconstruction. | 04-16-2009 |
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 |
20090306586 | LATERALLY-EXPANDABLE ACCESS CANNULA FOR ACCESSING THE INTERIOR OF A HIP JOINT - A laterally-expandable access cannula comprising:
| 12-10-2009 |
20100036440 | COLLAPSIBLE BONE SCREW APPARATUS - A collapsible bone screw for healing bone fragments across a bone fracture includes an externally threaded inner screw member and an externally threaded outer screw member. The inner screw member is initially screwed into an inner bone portion. An unthreaded portion of the outer screw member is movably joined to the inner screw member. The outer screw member is screwed until it gains purchase in an outer bone portion. As impaction occurs over time, the collapsible bone screw apparatus may shorten in length as the two screw members slide, telescope or otherwise axially move toward each other to shorten the overall length, thereby preventing any portion of the screw apparatus from protruding out of the bone. A bone screw kit of multiple inner and outer screw members are provided as well as a method of surgically fastening bone fragments. | 02-11-2010 |
20100268241 | METHOD AND APPARATUS FOR ACCESSING THE INTERIOR OF A HIP JOINT, INCLUDING THE PROVISION AND USE OF A NOVEL TELESCOPING ACCESS CANNULA AND A NOVEL TELESCOPING OBTURATOR - A telescoping access cannula comprising:
| 10-21-2010 |
20100280526 | Medical Device With Articulating Shaft Mechanism - A medical device with an articulating shaft assembly includes at least one slat member which has a cross section that allows it to be substantially flexible in a first plane and relatively stiff in the plane perpendicular to the first plane. A bendable section located at the working end of the device includes at least a portion of one or more slat members, such that the bendable section will articulate in the first plane in response to tensive and/or compressive forces applied to the bendable section. The device also includes a shaft section which is coupled to and supports the bendable section, and at least one control mechanism arranged to cause the tensive and/or compressive forces needed to articulate the bendable section to be applied to the bendable section. | 11-04-2010 |
20110066165 | METHOD AND APPARATUS FOR TREATING A HIP JOINT, INCLUDING THE PROVISION AND USE OF A NOVEL SUTURE PASSER - A suture passer comprising:
| 03-17-2011 |
20120010670 | METHOD AND APPARATUS FOR ACCESSING THE INTERIOR OF A HIP JOINT, INCLUDING THE PROVISION AND USE OF A NOVEL INFLOW ACCESS CANNULA - An inflow access cannula system for allowing an instrument to access a remote surgical site, wherein the instrument comprises a distal portion having a smaller diameter and a proximal portion having a larger diameter, the system comprising:
| 01-12-2012 |
20120123448 | METHOD AND APPARATUS FOR PASSING SUTURE THROUGH TISSUE - A suture passer comprising:
| 05-17-2012 |

| 02-14-2013 |
20130218173 | SURGICAL INSTRUMENT FOR MANIPULATING AND PASSING SUTURE - A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. | 08-22-2013 |

20140222033 | SURGICAL INSTRUMENT FOR MANIPULATING AND PASSING SUTURE - A suture manipulating instrument for passing and retrieving suture through a tissue includes a handle mechanism, an elongate shaft extending from the handle, and a working distal end. The working distal end includes a needle body, a lumen defined by the needle body, a tissue penetrating distal tip, and a lateral slot. A preformed inner member is movably disposed within the lumen of the needle. The handle mechanism is used to extend the wire from the lateral slot of the needle, and to retract the wire into the lateral slot, allowing the working end of the instrument to grasp and manipulate suture by pinning and/or trapping the suture against the needle. In embodiments the inner member is further retracted within the needle lumen, drawing a length of suture into the needle lumen. The suture is subsequently ejected from the needle lumen to form a suture loop. | 08-07-2014 |
