摘要:
An apparatus for closing an aperture comprising a horizontally extending member and elongated strand portions having extremity portions curving inwardly. The extremity portions have shape memory characteristics seeking to cause the extremity portions to curl to retain tissue engaged thereby when delivered from a delivery member. A central portion extends between the horizontally extending member and the elongated strand portions.

Clip apparatus for closing a vessel aperture resulting from insertion of a surgical implement comprising an elongated strand comprising a central portion and extremity portions extending from said central portion. The tips of said extremity portions remote from said central portion are shaped to retain tissue encountered thereby. The extremity portions have memory characteristics seeking to cause said extremity portions to curl with respect to said central portions to retain tissue engaged thereby when said strand is in an unconstrained disposition.
摘要:
A surgical apparatus for removing deposits from an interior of a vessel comprising a rotatable shaft and a rotatable tip mounted to the rotatable shaft which is rotatable about its longitudinal axis upon rotation of the shaft to remove deposits from the interior of the vessel. The tip has a distal portion, a proximal portion and an intermediate portion between the distal and proximal portions. The intermediate portion is defined by a plurality of transverse cross-sectional areas, wherein each transverse cross-sectional area defines first and second axes substantially perpendicular to each other to define a width dimension along a first axis and a height dimension along the second axis. The height dimension is greater than the width dimension.

Display cards are provided for displaying sunglass attachments for eyeglasses, specifically inexpensively produced mountings to display a drop-on sunglass attachment from a display rod that allow a prospective purchaser to sample the drop-on sunglass attachment prior to purchasing without removal of the drop-on sunglass attachment from the display card. An upper and lower substantially rectangular, planar members slightly greater in width than a drop-on sunglass attachment are provided, including a horizontal slot located in the upper member for receiving a molded hook in the top of the drop-on sunglass attachment. The lower member has essentially equal dimensions as the upper member, and hingedly connects to the upper member through a thin segment only as wide as the nosepiece of the drop-on sunglass attachment. Upon engaging the horizontal slot of the upper member with the molded in hook of the sunglass attachment, the lower member can be folded through an arc, engaging the bridge of the sunglass attachment through the thin segment of the base planar member, and mating with the upper member, securing the sunglass attachment between the lower and upper members. Thus attached, the display card does not interfere with the test fitting of the sunglass attachment. The display card contains a hole that can be selectively engaged with a cantilevered merchandising display rod.
摘要:
A device for closing an aperture in a vessel wall comprising an elongated member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture. The elongated member has a dimension to prevent egress of fluid through the aperture. A material forms two curved legs having ends positionable external of the vessel. The legs curve in different directions and a retention portion is formed in the material to retain the legs during placement of the elongated member inside the vessel.
摘要:
A device for closing an aperture in a vessel wall comprising a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. Two curved legs are provided having portions positionable external of the vessel and curving in different directions. At least one retention member is positioned between the covering member and curved legs and positionable external of the vessel.
摘要:
A method of locating a vessel lumen to enable placement of a vascular hole closure device comprising the steps of providing a syringe containing a fluid therein, connecting the syringe to an elongated instrument, exerting a force on the syringe plunger as it is inserted through the tissue towards the vessel wall, and detecting movement of the syringe to eject the fluid to determine entry of the elongated instrument into the vessel lumen.

摘要:
A device for closing an aperture in a vessel wall comprising an elongated member positionable inside the vessel against an internal opening of the aperture and having a dimension exceeding a dimension of the internal opening of the aperture to prevent egress of fluid through the aperture, and at least two curved legs positionable outside the vessel to help retain the elongated member in position.
