Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism either within the anchor itself of positioned proximally of the anchor may allow for the uni-directional translation while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This unidirectional anchor locking mechanism facilitates the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.

A device is described that can be used by surgeons to provide accurate tissue-lifting and tightening maneuvers that uses minimal external incisions, enhances accuracy, reduces inadvertent consequences while speeding the procedure. The device is comprised of a shaft with a relatively planar but possibly lenticulate or even slightly curved tip that can divide and energize various tissue planes causing net contraction via the fibrous tissue modification. Various forms of energy can also be delivered to cause desirable tissue alterations.

Connectors for interconnecting rods, fixed to vertebrae and other bones of a subject include a body portion and two recesses or pockets for receiving the rods. These connectors are generally able to be secured to the rods by a tightening a fastener or retaining member from above the spine, which can facilitate the procedure for the surgeon. The connectors can include rotatable or stationary pockets, mating members that pivot and/or translate within the coronal plane of the subject to adjust to the positions of the rods, and extension shafts that pivot to adjust for rod angle.

The invention provides a thin-wall sliding sleeve disassembling fixture. The thin-wall sliding sleeve disassembling fixture comprises a puller nut and a puller screw. The puller screw is in threaded connection with the puller nut. One end of the puller screw is provided with a clamping jaw. The puller screw is in threaded connection with the clamping jaw. A bracket and a hydraulic system are installed between the puller nut and the clamping jaw. The bracket and the hydraulic system are sheathed on the puller screw. The bracket is adjacent to the clamping jaw. The hydraulic system is adjacent to the puller nut.

The thin-wall sliding sleeve disassembling fixture is small in volume, light in weight, smooth and steady in movement, and safe and convenient in operation, and capable of preventing the deformation of the thin-wall sliding sleeve and thescratching of a hole wall in an disassembling process.

A method is described for modifying at least one property of a tissue of or near a nasal valve of a nose, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in a nasal airway. The method may involve contacting a treatment element of a treatment device with the at least one tissue inside the nasal airway, with sufficient force to at least temporarily deform the at least one tissue, applying energy to, or removing energy from, the at least one tissue, using the treatment element, and removing the treatment element from the nostril.

A shoelace reel includes a support seat, a spool rotatably mounted in the support seat, a shoelace having two distal ends each secured to the winding zone of the spool, a limit sleeve mounted on the support seat, a drive member rotatably and movably mounted in the limit sleeve, and a control knob rotatably and movably mounted on the limit sleeve and connected to the drive member. Thus, the user only needs to rotate the control knob to tighten the shoelace and to pull out the control knob to loosen the shoelace. In addition, the user only needs to operate the control knob to tighten or loosen the shoelace, so that the user can tighten or loosen the shoelace by his one hand only.

A body brace for a wearer has a combination of adjustment mechanisms and fasteners to help fit the body brace to a wearer. A wearer first fastens the body brace about his abdomen and lumbar regions to generally fit the body brace around the wearer's waist. The wearer then adjusts one set of adjustment mechanisms that adjust an upper and lower circumference of the brace to allow the brace to fit both straight and pear-shaped bodies. Lastly, the wearer adjusts a second set of adjustment mechanisms that tighten a rear panel of the body brace against a lumbar region of the wearer. Preferably, the adjustment mechanism that is used to tighten the rear panel is an advantaged adjustment mechanism to allow for fine-tuning and a snug fit.

A tourniquet band is made of an elastic material and has a plush surace on one side and a series of hook fastener material patches on the reverse side. The woven structure includes a series of parallel elastic threads covered by a dense yet loosely coiled bundle of non-elastic threads. The non-elastic threads are oriented to form the plush surface while allowing the elastic core thread to elongate for applying pressure to a body part by elastic compression when the tourniquet is wrapped around the body part and secured by joining the hook material with the plush surface.

A clamp for a sanitary fitting includes a first and a second semicircular part that are circumscribed by a flexible cable tie. Each semicircular part has a concave side and a convex side. A channel is formed in each concave and each convex side. The concave channels accommodate a flange of a sanitary fitting when the first and second semicircular parts are disposed in confronting relation to one another. The cable tie positioned in the convex channels circumscribes the confronting semicircular parts. A cable tie catch slidingly receives a free end of the cable tie when the cable tie circumscribes the first and second semicircular parts. A marker on the cable tie registers with the catch or another marker on the cable tie when the cable tie is under a predetermined amount of tension to ensure that the same amount of tension is consistently applied to the cable tie.

A harness clamp tie includes a locking head and a flexible strap extending outwardly from the locking head. The strap is insertable through the locking head to form a loop that can be used at least one item. A pawl in the locking head secures the strap. Nonslip rails formed along the outer edge of the strap face and clamping rails formed on the locking head aid in securing small items. Conic friction points are formed on both sides of the strap surface to provide a mechanical grip for pulling the strap through the locking head. A mounting fastener extends from the locking head in the opposite direction. The fastener secures the tie to a mounting structure such as an aperture in a panel. The fastener includes a pair of flexible winged springs which help to stabilize the tie and hold the tie perpendicular to the panel.

A clamp for aligning the confronting ends of two or more workpieces, preparatory to their permanent joining. This clamp utilizes a chain of cruciform cross-section, and one or more alignment apparatuses, to encompass and secure the first workpiece, and align the remaining connecting workpiece(s). The chain may be fitted to the first workpiece, using color coding to select added chain-link sections for larger workpieces. Each alignment apparatus is slid on the chain, and secured by a spring-biased detent. The chain is then secured about the first workpiece. The alignment apparatus overlies the connecting workpieces, which are then aligned for joining, using one or more adjustable fasteners mounted on the alignment apparatus.
