    摘要: A medical device for endoscopic access of a body cavity and a method of percutaneously placing inner and outer access sheaths of the device into the body cavity. The medical device includes inner and outer access sheaths and a dilator which is inserted into the outer sheath and has a shoulder or a shoulder piece for abutting against the proximal end of the outer sheath. The device also includes a wire guide that is percutaneously inserted into the body cavity via an introducer needle. The dilator and outer sheath are placed over the wire guide to dilate the puncture site and introduce the dilator and outer sheath into the body cavity. The dilator comprises an elongated cylindrical member having a passageway opening distally from the conically-shaped distal end and from an outside lateral wall of the dilator about the proximal end. The dilator also includes an end cap which is utilized to force the dilator and the outer sheath through the puncture site and into the body cavity. After positioning in the body cavity, the dilator and wire guide are removed through the outer sheath. The inner sheath is then inserted through the outer sheath into the body cavity. The proximal ends of both the inner and outer sheaths include seals for maintaining insufflation of the body cavity. The inner sheath includes a shoulder piece having a chamber and a side port for connection to an insufflation gas line.

    摘要: A medical device (10) for localizing a nonpalpable breast lesion (20). The device includes a tubular introducer needle (11) and a wire guide (14) positioned therein for inserting into a breast (25) to the site of the lesion. The wire guide includes a distal portion (16) which is preformed into a resilient helical coil configuration for locking into position about the lesion. The distal portion includes a superelastic metallic alloy for maintaining the helical coil configuration after repeated extensions from and retractions into the needle passageway. With a visualization aid such as an X-ray film or ultrasound, a radiologist typically inserts the needle with the wire guide positioned therein into the breast to the site of the lesion and extends the distal portion of the wire guide from the needle. The distal end of the needle includes a plurality of indentations for enhancing the ultrasound visualization thereof. As the distal portion of the wire guide emerges from the needle, the acuate distal end (17) of the wire guide cuts into and scribes a helical path about the tissue distal to the lesion. The remainder of the distal portion of the wire guide follows the path scribed by the acuate distal tip and locks about the tissue distal to the lesion. Should the needle and wire guide not be appropriately positioned, the distal portion of the wire guide is retracted into the passageway of the needle to reposition the needle and guide. After desired positioning, the needle is removed with the wire guide remaining in a locked position distally about the lesion for guiding guides the surgeon to the lesion site during subsequent surgery.

    摘要: An apparatus (10) for filtering blood in a blood vessel of a patient comprises a catheter (30) which is introduced into the blood vessel and advanced to a desired location within the blood vessel, a positioning means (12) having a filter (13) distally attached thereto to be guided through the catheter. In use, the filter is positioned at a location beyond the distal end of the catheter within the blood vessel with the positioning means. The positioning means is then locked to the catheter. The catheter is then anchored to an object located outside of the blood vessel. Thereafter, an amount of blood is filtered within the blood vessel with the filter. The filter can be readily repositioned by unlocking the positioning means from the catheter, repositioning the filter within the blood vessel with the positioning means and then relocking the positioning means to the cather.
