摘要： A biopsy specimen gathering system has been developed which includes a biopsy needle having an aspirating chamber operatively coupled thereto. An elongated tubular sleeve forming a sleeve guard is provided, the sleeve guard having a closed base and an open top with the inner periphery of the upper end of the sleeve having a surface for sealingly engaging the outer periphery of the base of the aspirating chamber. The outer circumference of the shank of the sleeve guard has a plurality of spaced-apart circumferential grooves formed therein to provide spaced score grooves to a depth sufficient to permit the shank to be broken upon flexure thereof, thereby leaving an open ended sleeve firmly attached to the aspirating chamber and exposing a desired length of the tubular needle.

摘要： Pressure-sensitive adhesives which possess absorptivity and/or permeability properties to remove transepidermal wager loss and/or other bodily fluids that come into contact with the adhesive, in combination with a fine balance of cohesion and adhesion properties, can be formulated by controlling the crosslinking of a polyurethane polymer having excess hydroxyl functionality, a glass transition temperature of less than about 0.degree.C, a moisture absorption of at least about 20% of its weight and/or a moisture vapor transmission rate of at least about 300 grams/meter2/24 hours measured at 37.degree.C and a 90% relative humidity gradient. Adhesives of these polymers possess a peel adhesion to human skin of between about 0.3 and 4 newtons/cm width of the polymer or adhesive.

摘要： A biopsy aspirating device for gathering soft tissue samples comprising a syringe having a barrel, with a plunger sealingly received within the barrel to form a chamber with a controllably variable volume, and with a hollow sample-receiving needle mounted on a needle mounting boss attached to the barrel. The needle mounting boss has a bore formed therein to provide communication between the needle bore and the barrel with sample blocking means having an abutment surface thereon being provided to engage the sample and retain the sample in a position to prevent direct contact between the sample and the bore formed in the boss. The plunger is secured to the conventional gripping shaft, and the gripping shaft has means for releasably engaging the proximate end of the barrel at controllable axial dispositions therealong, in use, the needle Is used to puncture the body, and the tip of the needle is advanced until it reaches a point adjacent the organ from which the tissue is to be collected. At this point, the plunger is withdrawn and locked into engagement with the barrel, so as to form a partial vacuum within the barrel. The advancement of the needle is continued, thereby gathering a sample of tissue from the desired organ, with the tissue sample moving the needle shank until contact is made with the abutment surface.

摘要： Means for obtaining muscle tissue specimens from a body and comprising a generally cylindrical shaft having a tapered and pointed distal puncturing and cutting tip, and with coaxially disposed sheath means having a sharpened forward cutting edge slidably enveloping the shaft. A sample receiving cavity is formed in the shaft and is provided with a generally sharpened hook in the forward portion of the cavity. The hook has a point directed toward the proximate end of the shaft and comprises an overhanging barb forming a portion of the sample retaining cavity. The sheath is slidable over the shaft between retracted and extended dispositions, with the forward edges of the sheath enclosing the barb when the sheath Is In its forward predetermined disposition, and with the sharpened tip of the barb being exposed when the sheath is in retracted disposition. The forward sharpened cutting edge of the sheath forms a cutting edge which separates that portion of the sample retained within the sample receiving cavity from the bulk of the tissue, with the separation being in the form of a clean extraction cut. For removal of the sample, simple retraction of the device is possible.
