摘要:
A pressure injection syringe with an actuator that includes a plunger for pressurizing viscous fluid material within a chamber. The plunger distal tip includes a high pressure seal defined by a seal member within a seal seat. The high pressure seal is viscoselective to permit air passage therepast for aspiration, and to prohibit viscous material passage therepast during actuation of the actuator wherein high pressure is applied to the material within the chamber. The viscoselective seal may be defined for example by small axial openings in the seal seat that permit aspiration of air therepast during initial plunger insertion into the chamber, but fluid escape is prohibited by the seal member when the seal member is pressed firmly against a collar of the plunger proximally adjacent the seal seat by initial engagement of the seal member with the viscous material, thus completely sealing the chamber at the proximal end thereof.

A locker for securing one or more tensioning members includes a locker body having a first aperture, a second aperture, and a passageway extending therebetween. A pin is coupled to the locker body so as to traverse the passageway and is movable between a latent condition wherein the tensioning members are movable with respect to the locker body, and an activated condition wherein the tensioning members are prevented from moving relative to the locker body. A method of using a suture locker includes delivering the suture locker to a surgical site via a catheter assembly and actuating the pin so as to move the locker from the latent condition to the activated condition.

An athletic shoe cleaning device includes cleaning teeth affixed to a handle. Pairs or opposed cleaning teeth are provided which have a first section and a second section joined by an angle suitable for cleaning golf shoe spikes having multiple nubs or flanges. The cleaning teeth are especially suited for removing debris from circular or softer type golf spikes.

The present invention provides an underdrain having an improved spout. The underdrain has particular utility in the construction of both single-well and microarray filtration devices. In a principal embodiment, the underdrain is characterized by its incorporation of a straight-walled, roughly-textured spout, the spout being provided with microhole(s) at a terminal end thereof for the discharge of fluid conducted through the underdrain. An array comprising several of such underdrains can be mated with a corresponding array of wells, with separation material (e.g., membrane material) provided therebetween. The resultant microarray filtration device can be used for conducting several fluid assays contemporaneously with, for example, good “pendant drop” control and low “cross-talk”.
摘要:
A simple, golf swing training device and method of training which provides a lightweight, completely portable device for teaching and practicing a proper golf swing, and more particularly to a golf swing practice device and method to train a golfer to rotate his body throughout the golf swing and thereby train the body to know the feel of a correct golf swing by air swinging. The device comprises a rod of predetermined length and diameter having a distal end and a proximal end; a utility belt attached to the proximal end of the rod for positioning the rod on a golfer; a club receptacle attached to the distal end of the rod for receiving a golf club shaft, wherein the golf swing training device facilitates the training of the golfers body to know the feel of a correct golf swing.
摘要:
A simple, lightweight, portable golf swing training device to fix the rear knee of a golfer in the correct position at setup and to restrict its lateral movement away from the target during backswing, with no interference of the forward movement of the knee, hips or body during the downswing, impact or follow through. The device comprises a base unit with a vertical rod, which has a height that extends at least to the rear knee, affixed thereto. A golfer uses the device by positioning his rear foot on the base rearwardly of the vertical rod and his rear knee forwardly of the vertical rod. By restricting the knee's freedom to over rotate or slide laterally away from the target or collapse away from the target line; the golfer's hips are prevented from either over rotating and/or sliding laterally away from the target. A video camera may be used to videotape a golfer before and during the use of the golf swing training device to compare knee positions.

摘要:
A plate liner detachably engageable onto a microarray plate (or underdrain plate component thereof), suited for preventing or confining pendant drop formation. It is provided either as a stand-alone item, or—preferably—in kit form, within a sanitary package, together with other pre-matched microarray filtration components.
摘要:
A golf putting training system for a golfer is disclosed generally comprising a linear measurement device that is placed on the ground such that a golf ball is placed at one end and a stopper for engaging a putting head is positioned along the measurement device at a desired distance from the ball. A golfer putts the golf ball, taking a backswing that moves the putter head to the surface of the stopper prior to accelerating towards the ball. The golfer then compares the distance between the end of the measurement device and the stopper to the distance between the end of the measurement device and the final destination of the golf ball. In this way, the golfer can calculate a backswing-to-putt ratio to quickly determine the required backswing distance for any desired putt distance for a given stroke acceleration rate.

Abstract of the DisclosureA dilator (10) for creating tracheostomies in one pass. Dilator (10) includes a generally linear shaft (12) extending from a proximal end (14) and beginning at a distance therefrom, gradually and continuously through a curved distal portion (16) of continuously decreasing diameter (from about 38 french) to a distal tip portion (18) of small diameter of about 12 french at distal end (20). The outer surface of the insertable portion is treated or hydrophilically coated to minimize friction, and the gradual taper gradually widens the tracheal entrance opening (44) between tracheal rings (46,48) with minimal trauma. The wall thickness gradually decreases from the linear shaft (12) to the soft distal tip portion (18). The continuing curve of the distal portion (16) enables the increasingly longer inserted portion of the dilator to remain situated in the trachea (50) during insertion and for the distal tip portion to clear the posterior tracheal wall.
