Abstract: A stent delivery catheter comprises a catheter body having a proximal end, a distal end, and a guidewire lumen extending from the distal end to at least part way between the proximal end and the distal end. A balloon is disposed over the catheter body near the distal end, and a stent is positioned over the balloon. The stent has a proximal end, a distal end, and a side opening between the proximal end and the distal end. A side sheath is coupled to the catheter body and has a proximal end, a distal end, and a guidewire lumen extending between the proximal end and the distal end. The proximal end of the side sheath is located between the proximal end of the catheter body and the balloon, and the side sheath exits out of the side opening of the stent.

Abstract: A stent and stent catheter for intra-cranial use. The stent is a rolled sheet stent and is releasably mounted on the distal tip of the catheter by means of a non-sliding retention and release mechanism. The non-sliding release mechanism is operated remotely at the proximal end of the catheter by means of a linear translator. The stent is rolled tightly on the distal tip of the catheter and flexibility of the tightly rolled stent is promoted by ribbed or slatted construction (or, alternatively, slotted construction) in which the various layers of the stent are provided with numerous slats which counter align when the stent is expanded to form an imperforate wall from a plurality of perforate layers.

Abstract: An apparatus for sucking out an object stuck in a person's throat, comprising hollow first and second bellows elements each having an orifice with a one-way valve and an exit valve, a tube structure comprising first and second legs having free distal ends outside the first and second bellows element respectively and proximal ends extending into at least the respective orifices, the first leg and the second leg joined at their respective free distal ends to form a double hose having a pliable sealing structure integral thereto at a distal end to seal the trachea and esophagus, and a handle element connected to a top portion of the first and second bellows elements to contract the first and second bellows elements. When the handle is released a sucking of air through the tube structure occurs and the first and second bellows elements expand back to their original size.

Abstract: There is described method and apparatus for taking a biopsy wherein the apparatus is formed of a biocompatible cylindrical member with an outer wall and a hollow core, the cylindrical member having a longitudinal axis. An opening in the outer wall of the member is provided and a cutting device cuts tissue entering the opening as it travels along the opening. Cut tissue is treated with a coagulating agent or member so that the coagulation occurs concurrently or just after the tissue is cut wherein the coagulation occurs at a trailing edge of the opening as it travels.

Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for treating an area of vulnerable plaque. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by straight links. Alternatively, the cylindrical rings of the distal section and the cylindrical rings of the proximal section are connected directly to adjacent cylindrical rings. The stent has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. A central section is positioned between distal and proximal sections and is aligned with the area of vulnerable plaque to enhance growth of cells over the fibrous cap of the vulnerable plaque to reinforce the area and reduce the likelihood of rupture.

Abstract: A method of and apparatus for sealing access openings into blood vessels using an expandable member in the blood vessel on a control member that extends out through the access opening and an applicator which inserts a preformed sealing material into the access opening over the control member to keep the control member and expandable member centered in the access opening and withdrawing the collapsed expandable member back through the sealing material after the access opening is sealed.

Abstract: Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by a removable tubular restraint. In one application, the sheath is utilized to introduce a formed in place orthopedic fixation rod such as for use in spinal fixation procedures.

Abstract: An expandable stent for percutaneous procedures comprises a tubular structure disposed about a longitudinal axis and a plurality of fingers. The plurality of fingers, upon expansion of the stent, extends from the tubular structure about a second longitudinal axis which is angularly offset from the first longitudinal axis. At least one of the plurality of fingers has a length that is greater than that of the other fingers.

Abstract: A bifurcated or straight intravascular folded tubular member is deliverable percutaneously or by small cutdown to the site of a vascular lesion. Its inserted state has a smaller nondeployed diameter and a shorter nondeployed length. The intravascular tubular member has a folded tubular section that is unfolded following insertion into the blood vessel. The length of the intravascular folded tubular member is sized in situ to the length of the vessel lesion without error associated with diagnostic estimation of lesion length. The folded tubular member is self-expandable or balloon-expandable to a larger deployed diameter following delivery to the lesion site. An attachment anchor can be positioned at the inlet or outlet ends of the intravascular folded tubular member to prevent leakage between the tubular member and the native vessel lumen and to prevent migration of the tubular member. The attachment anchor has a short axial length to provide a more focal line of attachment to the vessel wall.

Abstract: The present invention relates generally to the field of embolic protection and, more particularly, to systems for locking a shaft relative to a hub assembly. In addition, a method for securing a shaft relative to a hub assembly is disclosed.

Abstract: The present invention is directed to a flexible expandable stent for implantation in a body lumen, such as a coronary artery. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of links which be polymeric or metallic. Varying configurations and patterns of the links and rings provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis and providing a low crimp profile, enhanced stent security and radial stiffness.

Abstract: An active cannula which does more than merely maintain a passage is usable to create and/or enlarge a passage, to position a scope or instrument, to move or locate tissue, etc. The cannula can vary in size or shape as needed, intraoperatively. Because a cannula of the present invention is expandable, the surgeon can make a relatively small incision, stretch the tissue with the expandable cannula, contract the cannula and remove it, allowing the skin to come back to its unstretched condition. Thus, a smaller incision can be made to fit the same size instrument. The cannulas can assume such a non-circular shape, to fit into a natural skin opening and cause less trauma. The devices can be used to seal off a space, expand an existing space or a potential space for working or visualization, move tissue (for example, to stretch an incision), or protect tissue.

Abstract: An improved multi-bite bone cutting rongeur with an ultrathin foot plate and a disposable cutting element and storage chamber unit is disclosed. The present invention has an integrated cutting element and storage chamber unit that is truly disposable, rather than merely replaceable. The present invention requires the use of no tools or special assembly. The chamber is simply placed onto the shaft whereby it is immediately locked into place by the use of the instrument.
