The present invention relates to an apparatus and method for securing a connector conduit to a hollow organ. The method comprises forming a hole in a wall of the organ; inserting a connector conduit through the hole in the wall of the organ until a flange element comes into contact with the wall of the organ, the flange element being positioned on the connector conduit; and engaging a retention means with the wall of the organ to prevent movement of the connector conduit relative to the wall of the organ, the retention means being positioned on the connector conduit. Exemplary retaining means include a plurality of retaining pins positioned circumferentially around the connector conduit, a plurality of prongs positioned circumferentially around the connector conduit, a balloon positioned on the connector conduit, a torsion spring positioned on the connector conduit, a spiral spring positioned on the connector conduit, or combinations thereof.

An improved bolt and bolt carrier with integral gas key having an extension nozzle threadedly secured and pinned to the gas key for use with a direct gas operated firearm is provided. The extension nozzle is designed to receive a portion of the host firearms gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pins annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end and an extractor recess. The extractor recess is constructed to accommodate an enlarged extractor claw while not undercutting the bolt lugs adjacent thereto. The extractor engages approximately 57% more of a seated ammunition cartridges rim as compared to some prior art AR15/M16 type extractors used with automatic firearms chambered in 6.8 SPC. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

A spine implant for a TLIF surgical procedure is configured to be steered into place during implantation in conjunction with a complementary insertion instrument. The cage of the implant is constrained to a limited range of rotation about a post carried by the cage. The insertion instrument is configured to hold the post while controllably rotating the cage relative to the post in order to angularly position the implant during implantation. Range of rotational motion is controlled by the configuration of a groove in the post. A retaining pin of the implant extends from the cage into the groove of the post to rotationally connect the cage to the post.

A surgical instrument is adapted for applying a plurality of surgical fasteners to body tissue. The surgical instrument includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end. The end effector is shaped and dimensioned for supporting a cartridge housing and an anvil, the cartridge housing and anvil being relatively movable by actuation of a closure mechanism. The surgical instrument further includes a firing mechanism associated with the end effector and the cartridge housing for selective actuation of the surgical fasteners features. The surgical instrument also includes a retaining pin for enclosing tissue between the anvil and the cartridge housing. The retaining pin is moved by actuation of the closure mechanism from an open first position to a closed second position. A manual actuator is associated with the retaining pin for moving from the second position back to the first position and alternatively moving the retaining pin from the first position to the second position.

A connector for a windshield wiper, and a wiper blade assembly including same, that accommodates multiple pin-type windshield wiper arms having varying pin lengths and locking mechanisms. The connector for connecting a windshield wiper assembly to a wiper arm may have a peripheral wall having at least two opposing peripheral side walls and a top surface extending from one of the two opposing peripheral side walls to the other. The opposing peripheral side walls may each have a retaining pin aperture aligned with one another and sized to be capable of slidably accepting a retaining pin of at least one pin-type windshield wiper arm.

A spring loaded quick release pin and tubular receiver with a retainer pin configured to secure the quick release pin in a shackle, clevis, yoke or forked rod end. The receiver is welded to a shackle or cast with the shackle as a single body. One end of the quick release pin has aligned J slots that engage the retainer pin positioned in the receiver with a clockwise twist. The other end of the quick release pin has a cap and a spring loaded sleeve that biases the cross pin against outside of the second leg of the shackle. The spring bias keeps the short leg of the J slot engaged with the retaining pin. The quick release pin is removed with a push and counter clockwise twist. The invention includes a kit with a receiver, a bushing and a quick release pin for installing or retrofitting existing shackles.

The present invention is directed toward overcoming the disadvantages associated with previously known hairstyling devices, including but not limited to flexible snap clips. The apparatus incorporates a combination of a snap clip closure mechanism and a comb-like bottom with elongated teeth for gathering and holding hair.

A suspension system includes a composite leaf spring having an arcuate segment that is located between a retaining pin and a bumper. The retaining pin includes a shank surrounded by a resilient tube. The bumper is located adjacent a rear wall of the bracket opposite the retaining pin. The bumper includes an arcuate face to engage the outer arc of the arcuate segment while the pin is at least partially surrounded by the arcuate segment. The end of the composite leaf spring is thereby securely yet resiliently retained within the front leaf spring attachment system without penetrating fasteners.

The invention relates to a fixation device with clamping jaws and with rods connecting the clamping jaws, said rods being adjustable axially and angularly for positioning relative to the clamping jaws and clampable in the desired position, and with fixation and retaining pins that are receivable in a clampable fashion in the clamping jaws. According to the invention, a fixation pin applicator can be connected in a releasable fashion to the clamping jaws. A fixation pin can be brought into a desired position by means of the fixation pin applicator.

The present invention provides methods, compositions, and kits comprising snap-back primers used for forming 3′ hairpin structures, 5′ hairpin structures, and double hairpin structures. The hairpin structures may be used for detecting target sequences (e.g., such as small RNA target sequence), for detecting polymorphisms in target sequences (e.g., such as polymorphisms located near the 5′ or 3′ ends of the target sequence), or other nucleic acid characterization methods. In certain embodiments, the hairpin structures form invasive cleavage structures (e.g., in combination with a probe or upstream oligonucleotide) which may be cleaved by structure-specific enzymes in order to detect the presence or absence of a particular nucleotide or nucleotide sequence.

A cylindrical cotton module handling device includes an attachment having a pair of selectively spreadable, powered cylindrical tines adapted for supporting and rotating a module. Each powered tine is constructed from a cylindrical tube supported from a conventional L-shaped fork by a tubular sleeve received on, and dimensioned for fitting closely to, the horizontal leg of the conventional fork. The tubular sleeve is held in place by an L-shaped bracket forming a rearward extension of the sleeve and formed for embracing a region of the convention fork at the junction of its vertical and horizontal legs, with a retaining pin extending through vertical side plates of the bracket at a location just to the rear of the junction. An endless roller chain bearing arrangement is secured in encircling relationship to the tubular sleeve and supports the associated cylindrical tine for rotation. A hydraulic motor drive arrangement is mounted to the sleeve and has a shaft borne chain sprocket meshed with a drive chain carried by a rotating drive plates that are keyed to the cylindrical tube. A hydraulically retractable spike assembly is located inside a forward end section of the cylindrical tube and includes a plurality of spikes mounted for being selectively extended outwardly through holes in the tube for engaging a module wrapping during removal of the wrapping from the module.
