Publication number: 20150173778Abstract: Low profile reamers and methods of use are provided which can, in general, allow a hole to be drilled in bone. In one embodiment, a low profile retractable bone reamer is provided having an elongate shaft with a cutting element disposed on a distal end of the elongate shaft that can be configured to drill a hole in bone. The elongate shaft and cutting element can have first and second longitudinally separated portions that are movably coupled to each other. The reamer can be configured to move between a retracted configuration, in which a the reamer has a reduced, low profile configuration, and a non-retracted configuration, in which both longitudinally separated portions of the cutting element can be positioned adjacent to one another to form a single cutting element.Type: ApplicationFiled: March 5, 2015Publication date: June 25, 2015Inventors: Gregory R.

Publication number: 20150157308Abstract: Various exemplary methods and devices are provided for improved surgical sutures, suture systems, and methods for suturing. In general, the sutures, suture systems, and methods can allow a suture to form a secure, closed loop without tying a knot. The suture can include a barbed portion configured to be threaded through a hollow portion. The barbed portion can have a plurality of barbs thereon, which can grasp onto an inner wall of the hollow portion when disposed therein to help secure the loop at a desired size. The barbs can all be oriented in one direction that corresponds to a direction of movement of the suture when the loop is being tightened. Thus, the barbs can be configured to allow for a size of the loop to be easily reduced to any desired size to approximate tissue, but can be configured to resist subsequent expansion of the loop to ensure that the tissue remains in place.Type: ApplicationFiled: December 11, 2013Publication date: June 11, 2015Inventor: Mehmet Z.

Patent number: 9011472Abstract: Systems and methods are provided for passively dissipating a rotational speed of a fluid-driven rotatable shaft. In particular, a dissipation member is provided for dissipating the rotational speed of a shaft having an end effector formed thereon. As the rotational speed of the shaft increases, the dissipation member will apply a counter-torque to the shaft, thereby limiting the rotational speed of the shaft. In an exemplary embodiment, the counter-torque has a non-linear dependence on the rotational speed of the shaft, such that the counter-torque increases at a rate greater than a rate of increase in the rotational speed.Type: GrantFiled: January 24, 2006Date of Patent: April 21, 2015Assignee: DePuy Mitek, LLCInventors: Kevin J. Ranucci, Mehmet Z. Sengun

Publication number: 20140257346Abstract: A device having one or more adjustable loops or coils associated with an implant body for use in soft tissue reconstructions is provided. One exemplary embodiment of a device includes a body and a suture filament, with the filament being used to form a self-locking sliding knot disposed on a top side of the body and a plurality of adjustable coils that are substantially disposed on the body's bottom side. Terminal ends of the filament located above the body's top side can be passed through an opening of a Lark's Head knot from opposite sides, thus forming a self-locking sliding knot, and then the terminal ends can be tensioned to adjust a circumference of the coils. Changing a coil's circumference changes a location of a ligament graft disposed on the coil. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.Type: ApplicationFiled: March 11, 2013Publication date: September 11, 2014Applicant: DePuy Mitek, LLCInventors: Mehmet Z.

Publication number: 20140081320Abstract: Methods and devices are provided for securing tissue to bone. In general, a suture leader can have leading and trailing ends, and an inner passageway configured to receive a strand of suture therein. More specifically, the trailing end of the leader can be configured to receive the strand of suture therein to form an overlapping region of suture leader and suture. When the suture is positioned in the leader, an outer diameter of the leading end of the leader can be less than an outer diameter of the over lapping region. The leader can have a lower bending stiffness than the suture so that the leader can be more easily folded into a bend. In certain aspects, the suture leader can be formed from a substantially flexible, braided material so that the leader can be configured to contract when a pulling force is applied to the leader. In another embodiment, the suture leader can have a pre-formed crease configured to mate with a threading tool.Type: ApplicationFiled: September 20, 2012Publication date: March 20, 2014Applicant: DePuy Mitek, LLCInventors: Mehmet Z.

Patent number: 8425517Abstract: A high pressure fluid jet system is provided, which is useful for cutting hard material during a surgical procedure. The cutting of hard material is more efficient as the system delivers abrasive solid particles with the high pressure fluid. A method of effecting cutting during a surgical procedure is also provided. In an exemplary embodiment, a surgical tool that is effective to deliver a pressurized stream of fluid through a nozzle is provided, and the pressurized stream of fluid is delivered through the surgical tool and out of the nozzle to hard material within a patient to effect cutting of the hard material within the patient in a desired pattern. The fluid that cuts the hard material can include a delivery liquid having a plurality of abrasive solid particles that are formed from an organic material. The abrasive solid particles can be entrained in the pressurized fluid stream or the pressurized fluid stream can erode a solid or suspension form of the abrasive particles.Type: GrantFiled: July 22, 2011Date of Patent: April 23, 2013Assignee: DePuy Mitek, Inc.Inventors: Mehmet Z.
