    摘要: An introducer sheath for placement of a tubular shaft into the vascular system of a human subject. The introducer sheath has a tubular shaft, a side arm, and a hemostasis valve placed at a proximal portion of the introducer sheath. The hemostasis valve has an adhesive pad formed integral with the shell of the hemostasis valve. The adhesive pad is designed to attach and detach a proximal section of the introducer sheath to and from the skin of the human subject.

    摘要: An Endoluminal Tissue Excision Catheter (ETEC) is described which is capable of excising obstructive tissue from a vessel in a living body. The ETEC system operates by first passing a guide wire through the vessel and beyond the obstructive tissue. The ETEC catheter is then advanced over the guide wire until its distal end lies beyond the obstructive tissue. A closing catheter portion of ETEC is then pulled back from a cut/collect catheter portion of the ETEC thus exposing a cutting edge located at the proximal end of a cylindrical cutting blade located at a distal portion of the cut/collect catheter. A rotating means is then attached to the cut/collect catheters'3 s proximal end. The cut/collect catheter is then pulled back in a retrograde direction while rotating, thus cutting and collecting the excised obstructive tissue into a tissue collection chamber that is formed within the cylindrical cutting blade. The entire ETEC system including the cut/collect and closing catheters and the guide wire is then removed from the vessel. Means are provided to flush the collected tissue out of the tissue collection chamber after the ETEC catheter is outside of the living body.

    摘要: An atherectomy catheter is advanced over a guide wire in the anterograde direction to the site of an arterial stenosis. The distal end of the catheter is centered around the guide wire which has been previously advanced through the stenotic lumen. The catheter is then advanced over the guide wire with its sharpened distal end cutting through the stenosis. The atherectomy catheter can also employ rotation or vibration or an electrocautery current to enhance the catheter's cutting action. Suction applied at the catheter's proximal end is used to enhance the collection of plaque cut from the stenosis at the catheter's distal end so that the cut plaque enters a single passageway that lies between the outer surface of the guide wire and the inner surface of the cylindrical catheter.

    摘要: The present invention is a carotid sheath that has a proximal portion that is stiffer than the distal portion of the sheath as a result of the proximal portion having a higher durometer of the outer plastic coating of the sheath's proximal portion with a lower durometer for the plastic coating on the more flexible distal portion of the sheath. Another means to increase the flexibility of the sheath's distal portion compared to a stiffer proximal portion is by having a slightly smaller outside diameter for the outer plastic coating of the distal portion of the sheath. A more flexible distal portion of the sheath allows easier access for angiography, angioplasty or stenting when the sheath is used to access the tortuous path encountered when entering the carotid arteries.

    摘要: A sheath for percutaneous insertion into an artery includes a manually insertable sealing tab having a flexible hinge molded onto the sheath near its proximal end. The tab includes a cylindrically shaped stopper that can be inserted into the sheath's proximal end to prevent blood loss when there is no catheter inserted into the sheath. The stopper design allows a guide wire to remain in place or be advanced or pulled out of the sheath when the stopper is in place to seal the sheath's proximal end.

    摘要: Intra-arterial stents are frequently used subsequent to balloon angioplasty to maintain arterial patency. The most frequent cause for failure to maintain patency is the rapid growth of the injured arterial tissue through the openings in the stent, which rapid growth is called "intimal hyperplasia." Since irradiation from a radioisotope source is capable of selectively inhibiting the growth of hyperproliferating cells as compared with normal cells, a radioisotope material which forms part of the stent can be used to decrease the rate of arterial reclosure. The radioisotope could be placed inside the stent, alloyed into the metal from which the stent is made, or preferably, it can be coated onto the stent's exterior surface. Beta emitting radioisotopes having a half-life between 1 and 100 days would be best suited as a stent coating because of their comparatively short range of action within human tissue, and because of their comparatively short half-life. An anti-thrombogenic coating placed on the outer surface of the radioisotope stent would further reduce arterial reclosure by decreasing stent thrombogenicity.

    摘要: An atherectomy apparatus and method is disclosed for the purpose of surgical excision of atheromas which typically consist of plaque deposits that cause narrowing (stenosis) of an artery. The apparatus, called a pullback atherectomy catheter, cuts and collects obstructive material into a collection chamber as the catheter is pulled back through obstructive material within a human vessel such as an artery.
