  • Publication number: 20160278753
    Abstract: Devices and methods are disclosed herein for accessing the hip joint. A first device can be securely attached to the capsule of a joint. The first device can tent the capsule to increase the volume of the peripheral compartment. A second device can be biased against the first device to pierce the tented capsule and create a portal. Devices and methods are also disclosed herein for distending the capsule of a joint. A distention device may access a portal established within the capsule. The distention device can expand the capsule by applying an expansive force within the peripheral compartment. The distention device can maintain distention of the peripheral compartment while other devices access the joint.

  • Publication number: 20160262901
    Abstract: A shoulder implant device includes one or more fixation features including an acromial intrusion element and an inflatable humeral balloon portion that receives a fluid through the acromial intrusion element. The intrusion element comprises a valve that can receive multiple needle sticks to add or remove fluid to or from the inflatable humeral balloon. The device is implanted in a subacromial space such that the one or more fixation features at least secure the device to the acromion and the inflatable balloon portion rests against the proximal end of the corresponding humerus. Fluid in the balloon portion maintains separation of the acromion and the humerus to reduce or prevent impingement.

  • Publication number: 20160256286
    Abstract: 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.

  • Publication number: 20150223854
    Abstract: A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one of the outer housing or the inner shaft to the first portion of the tibia; coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first porti

  • Publication number: 20140303653
    Abstract: A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.

  • Publication number: 20140228865
    Abstract: A surgical suturing device (10) having an axis extending between a proximal end and a distal end is operable to move a suture (32) through body tissue (34). A handle assembly (110) is coupled to an elongated shaft (14) having a hollow configuration. An actuating rod (16) is disposed to extend between the handle assembly (110) and the shaft (14). A thumb actuation assembly is coupled to a proximal end of the actuating rod (16) for moving the rod both axially and rotationally. A needle assembly (2) at the distal end of the actuating rod (16) is movable with the actuating rod (16) between an extended state and a retracted state and at various angular orientations.

  • Publication number: 20140222033
    Abstract: 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.

  • Patent number: 8795294
    Abstract: 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.

  • Publication number: 20140194906
    Abstract: A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. A suture receiver is disposed adjacent to, or integral with, the opposite jaw to help disengage the suture carried by the bendable needle. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.
