Abstract: A medical clip dispenser apparatus for the pinching of a medical clip or staple about a portion of a mammalian body tissue. The apparatus comprises an elongated support beam having a distal end with a stationary lower housing thereon, and a distally movable hollow cinch slidably disposed on the lower housing. The cinch has a portion of a pair of closable jaws squeezably arranged therewithin. An elongated pusher has a generally cross-shaped pusher member on a distal end thereof in slidable engagement with the jaws, to keep the jaws apart from one another after a new clip has been pushed into position between the jaws.

Abstract: A trigger lockout device for a clip applying instrument. The lockout device includes a displaceable slider actuable by squeezing a trigger slidable in first and second directions a longitudinal axial direction within the barrel, and a block disposed within the barrel. When a first number of clips have not been applied and when the trigger is squeezed, the slider slidably engages and displaces the block and slides along a path in the axial direction to retrieve a clip of the first number of clips, and to insert the clip into the pair of jaws, and when a second number or none of the clips have not been applied, the slider engages the block to substantially prevent the slider from sliding along the path in at least one of the first or second directions such that the triggery cannot be unsqueezed.

Abstract: An indicating system for a clip applying device. The system has an indicator operatively connected to a trigger, wherein the indicator provides a signal when the trigger is moved to a position to operate jaws of the device to partially crimp the clip.

Abstract: A ladder for use with a clip applying device may include first and second protrusions extending from an end of the ladder along a lateral plane generally coplanar with the ladder or an orthogonal plane generally orthogonal to the ladder, in which the ladder may serially urge a clip outward from the surgical stapler, and the first and second protrusions may abut a cartridge in which the ladder is disposed.

Abstract: A medical clip applying device for crimping a clip. The device has a body assembly having a handle and a squeezable trigger, a barrel having a first end extending into the body assembly, a pair of jaws arranged on a second end of the barrel, the jaws actuable by squeezing action of the trigger, the second end of the barrel and the pair of jaws configured to be inserted into a body cavity, and a loading port in communication with the barrel. The barrel is configured to alternatively accept the insertion, through the loading port, of (a) a first cartridge type containing a plurality of clips of a first size or (b) a second cartridge type containing a plurality of clips of a second size, the first size being different from the second size.

Abstract: An advancement block for a clip applying device. The advancement block includes a body that proximally slides in the axial direction when a trigger is squeezed, and further distally slides in the axial direction when the trigger is released, and a toggle pivotably connected to the body, the toggle pivoting in a first direction about a pivot axis generally orthogonal to the axial direction and to a first position when the body proximally slides in the axial direction, the toggle further pivoting in a second direction about the pivot axis and to a second position when the body distally slides in the axial direction. When in the second position, the toggle engages and distally moves the ladder member such that the ladder member distally moves the rearmost clip in the axial direction.

Abstract: A clip applying device for the insertion and pinching of a medical clip within a mammalian body portion. The device comprises a housing supporting a proximal end of a delivery tube of the device. A pair of pinchable jaws are movably arranged at a distal end of the delivery tube. The device contains a plurality of preformed clips of a first width, the clips having leg portions, the clips also being movably disposed within the delivery tube between the housing and the jaws. A tool adjacent the jaws is arranged to enlarge the clips from a first width to a wider second width, as the clips emerge from the delivery tube.

Abstract: An elongated medical clip applying device having a handle grip assembly on a proximal end thereof and an elongated channel with a pair of squeezable jaws on a distal end thereof. A push rod arrangement is included having a distal end and a proximal end. The push rod arrangement is utilized for advancing a plurality of clips in a sequential manner between the jaws. The push rod includes a multiplier extender arrangement to increase the distance of travel of the distal end of the push rod arrangement a multiple of the distance of travel of the proximal or input end of the push rod arrangement.

Abstract: A medical clip applying device for crimping a clip onto a mammalian tissue. The clip applying device comprises a handle grip assembly having a handle and a pivotable trigger arranged onto the handle grip assembly. An elongated cartridge support channel is arranged onto a distal end of the handle grip assembly and extending through the handle grip assembly. A pair of jaws is pivotably arranged on a distal end of the elongated channel. A displacable cinch is arranged to slide onto and back from the pair of jaws to squeeze the jaws closed and to permit the jaws to bias open, respectively. A loading port is arranged on a proximal end of the handle grip assembly to permit the clip applying device to be loaded with a clip laden cartridge from the proximal end thereof.

Abstract: A balloon and method of manufacture for use in catheters for medical procedures, in particular percutaneous translumenal coronary angioplasty and other cardiovascular interventions. The balloon incorporates an inflatable membrane having a number of perpendicular ribs which have a higher resistance to collapse during deflation. A number of longitudinal ribs are provided which are preferably equidistantly spaced about a longitudinal axis and which extend between a proximal and distal end of the balloon. A number of triangular indentations are provided, wherein each triangular indentation is preferably equidistantly positioned between adjacent longitudinal ribs and each triangular indentation extends along a portion of the balloon between the proximal and distal ends. Each triangular indentation may extend through a perpendicular rib to reduce the resistance of the perpendicular rib to collapse during deflation.
