Limited flow cups are provided which deliver a metered amount of fluid to a user during a drinking motion.

A fluid displacement device, particularly for use of the device to pressurize balloon catheters, or the like. The device includes a plunger which is displaceable through a housing, and an actuating mechanism which engages the plunger. The actuating mechanism includes a nut member that is biased into engagement with a threaded portion of the plunger. The device has a press-to-release feature wherein the plunger is instantly releaseable by simply depressing a control surface to overcome a restorative spring force. Subsequently, the plunger can be translated using macro movements (i.e., by pushing or pulling the plunger).

Actuating mechanism for fluid displacement and pressurizing device

A fluid displacement device, particularly for use of the device to pressurize balloon catheters, or the like. The device includes a plunger which is displaceable through a housing, and an actuating mechanism which engages the plunger. The actuating mechanism includes a nut member that is biased into engagement with a threaded portion of the plunger. The device has a press-to-release feature wherein the plunger is instantly releaseable by simply depressing a toggle lever of the nut member to overcome a restorative spring force. Subsequently, the plunger can be translated using macro movements (i.e., by pushing or pulling the plunger).

An improved contact lens case which includes domes that are provided on hinged members. Preferably, the contact lens case is configured to efficiently utilize space and volume such that no more than 10 cc's of contact lens solution are required to disinfect contact lenses in the case. The hinged members are preferably non-planar which allows the domes to be provided on the hinged members, and allows the use of deep larger diameter, back-to-back cages on the stem, without having to resort to using more than 10 cc's of fluid to immerse contact lenses that are disposed on the domes, between each of the domes and a respective cage. Each of the hinged members has a cylindrically-curved shell form in which the axis of its curve is approximately parallel to the central axis of the central planar stem member.

Contact lens case

A tissue punch which is configured to operate by utilizing a spring force to compress tissue between a rotatable cutter blade and a tissue piercing element. The tissue punch is configured such that once the spring force is applied, the cutter blade can be selectively rotated by the user. The rotation of the blade, assisted by the compression from the spring force, causes the cutter blade to cut through the tissue. Three different methods for creating an anastomosis for locating a bypass graft are disclosed. In each method, bypass graft material is installed on a tissue punch and then sutured. Depending on the method, the tissue is punched either before or after the suturing.

An actuating mechanism for rapidly and selectively moving a threaded screw and nut member combination into or out of threaded engagement, particularly for use to pressurize angioplasty balloon catheters, or the like. The mechanism includes a housing and a threaded screw structure slidably displaceable through the housing. A nut member having partial threads is selectively engageable and disengageable with the threaded screw structure. The mechanism includes a carrier member and is designed to be assembled from the rear. The carrier member is preferably configured to be retainably engaged with the housing via a bayonet arrangement, such as a quarter-turn bayonet arrangement, and is configured to provide an audible indication when it is, in fact, properly and fully installed. Preferably, the housing is configured to receive a pressure gauge directly into a threaded bore on the housing. An improved method of assembling an actuating mechanism is also provided.

Inflator housing

A lancet device for lancing skin with a lancing needle of a lancet. The lancet device includes a housing and a lancet holder within the housing which is engageable with the lancet and moveable along a longitudinal axis of the housing. The device also includes a cam which has an end surface engageable with the lancet holder, cocking structure, biasing means between the cocking structure and the cam, and a trigger which is engageable with the cam for preventing rotation of the cam during actuation of the cocking structure. Actuation of the cocking structure causes the biasing means to become loaded between the cam and cocking structure, wherein upon disengagement of the trigger from the cam, the cam rotates, causing the lancet holder to move generally along the longitudinal axis of the housing. The lancet holder includes a cam follower member which contacts the end surface of the cam. The cam follower member rides along the end surface of the cam when the cam rotates in the housing.

Lancet device

A suturing device includes a housing having an axial lumen therethrough, at least one needle having a tip and being attached to the housing and being capable of traversing along a non-linear path from a first position wherein each such needle is substantially within the housing, to a second position wherein each such needle is substantially extended from the housing, and a suture releasably attached to the housing. The suture can be captured by the tip when each such needle is in the second position and pulled from attachment to the housing when each such needle is moved to the first position. Thereafter, the suture can be released from each such needle and a knot can be formed in the suture to close a wound.

Suturing device

A novel lancet device is disclosed, and the lancet device is compact and is designed to be held like a writing instrument during use. The device has a trigger relatively close to a firing end so the device can be easily maintained in the desired position while the device is being fired. A cocking knob on the device is rotated one hundred eighty degrees in order to cock the device and prepare the device for use. Only a relatively small amount of rotational force is needed to rotate the cocking knob. The device provides that a lancing needle does not extend and become exposed when the device is cocked. A thumb button is provided on the device, and the thumb button doubles as a depth adjustment knob and an ejector button. The thumb button can be pressed in order to simultaneously eject a tip platform along with the lancing needle, and can be turned in order to set the depth at which the lancing needle will pierce the fingertip when the device is fired. The thumb button can be pushed or rotated without applying an excessive amount of force.

Actuating mechanism for rapidly and selectively moving a threaded screw and nut member combination into or out of threaded engagement, particularly for use of the screw as a control fluid plunger to pressurize angioplasty balloon catheters, or the like, which mechanism includes a housing and a threaded screw slideably displaceable through the housing, and a nut member having partial threads engageable and disengageable with the threaded screw structure. A carriage structure is secured to the nut structure and arranged to enable reversibly translating motion together with the nut member relative to the screw structure to enable the selectively threaded engageability of the partially threaded nut member with the screw structure.
