An intraluminal stent made of a zig-zag or sinusoidal member defining a successive series of struts connected by apex sections and formed into a series of axially displaced hoop members wherein at least one of the hoop members has at least 5 one strut connected to a strut of an adjacent hoop. The connected struts may be connected by spot welding, continuous welding, or suturing, for example, or by a bridging member connected to each strut, and may be spaced along the length of the stent in a pattern to form a connective spine. The number of zigs of the zig-zag member in each hoop member may be varied, as can the zig length. A plurality of 10 connective spines may also be included.

An endoluminal prosthetic delivery system provides a delivery sheath possessing a yield strength capable of allowing implantation of the prosthesis with increased efficiency. An endoluminal prosthesis is inserted in a body in a radially compressed condition, and expanded at an implantation site, whereby a delivery sheath or the prosthesis itself possesses a yield strength sufficient to allow radial expansion of the prosthesis. A method of implanting an endoluminal prosthesis is also herein provided.

Medical device retaining sheath and medical device delivery system employing same

A stent delivery system deploys a stent having an inner periphery that defines an interior space extending lengthwise along at least a part of the stent and comprising at least one segment having relatively low column strength. The stent delivery system comprises a stabilizer which is disposed within the stent interior space and has a surface element adapted to engage the stent inner periphery in a region containing the low-column-strength segment. The surface element may comprise a sleeve or a coating having a high friction surface adapted to transmit adequate shear force to the stent to move the stent relative to the outer sheath upon deployment. Alternatively, or in addition, the surface element can include at least one radial protuberance. The protuberances may comprise rings of various cross-sections, axial lengths, or space sizes therebetween, or may be in the form of discrete barbs, bumps, or inflatable knobs arranged in a ringed configuration or helical pattern about the stabilizer. The stabilizer may also comprise an inner core and a heat-moldable compression sleeve surrounding the inner core, the heat-moldable compression sleeve having an outer surface comprising a plurality of protuberances defined by a thermal imprint of the stent inner periphery on the compression sleeve outer surface. A method for delivering a stent using a stent delivery system as described herein is also disclosed, as is a method for loading a stent and stabilizer having a heat-moldable compression sleeve into a stent delivery system.

Stent delivery system with nested stabilizer and method of loading and using same

A composite stent-graft tubular prosthesis includes an inner PTFE tubular structure, an outer PTFE tubular structure positioned about the inner PTFE tubular structure and a diametrically deformable stent interposed between the inner and outer PTFE tubular structures. The interposed stent is formed from an elongate wire helically wound with a plurality of longitudinally spaced turns into an open configuration. Each of the turns includes successive aligned upper and lower wave-like peaks. Selective ones of said upper and lower peaks are exposed exteriorly of the outer PTFE structure to render the composite prosthesis longitudinally flexible.

Mesh graft and stent for increased flexibility

An improved endoluminal prosthesis is described which possesses increased flexibility and longitudinal compliance with a stent/graft/stent securement member combination.

Tubular structure/stent/stent securement member

This invention is an intraluminal stent ( ) made of a zigzag or sinusoidal member defining a successive series of struts ( ) connected by apex sections ( ), and formed into a series of axially displaced hoop members ( ) wherein at least one of the hoop members has at least one strut ( ) connected to a strut ( ) of an adjacent hoop. The connected struts ( ) may be connected by spot welding, continuous welding, or suturing, for example, or by a bridging member ( ) connected to each strut ( ), and may be spaced along the length of the stent in a pattern to form a connective spine ( ). The number of zigs of the zigzag member in each hoop member ( ) may be varied, as can the zig length (L ). A plurality of connective spines ( ) may also be included.

Stent delivery system with nested stabilizer

Balloon yielded delivery system and endovascular graft design for easy deployment

An implantable microporous ePTFE tubular vascular graft exhibits long term patency, superior radial tensile strength and suture hole elongation resistance. The graft includes a first ePTFE tube and a second ePTFE tube circumferentially disposed over the first tube. The first ePTFE tube exhibits a porosity sufficient to promote cell endothelization tissue ingrowth and healing. The second ePTFE tube exhibits enhanced radial strength in excess of the radial tensile strength of the first tube. The stent provides patency to the endoprosthesis.

PTFE vascular prosthesis and method of manufacture

A tissue everting apparatus includes at least one elongated frame, at least one actuator slidably mounted to the frame and longitudinally movable between proximal and distal positions, a tissue everting bulbous tip, and at least two prongs which are laterally movable between open and closed positions. The bulbous tissue everting tip is positioned, for example, in the lumen of a vascular segment to evert the edge and the prong is closed to capture the everted edge of the vascular segment. The edge of a second vascular segment is everted and captured in a similar manner with the edges being brought together to form a flange-like structure to which one or more surgical clips may be applied to fasten the segments together.

Tissue everting apparatus and method

A device for securing a suture loop about bodily tissue includes a bead member having a longitudinal bore and an anchor member adapted to be slidably inserted within the bore of the bead member. The anchor member includes at least two axial compressible sections which define a passageway to receive two end portions of a suture loop. The axial sections collapse radially inwardly upon insertion of the anchor member within the bore of the bead member to securely wedge the suture end portions received within the passageway. The device has application in conventional and endoscopic surgical procedures including laparoscopic procedures.

Suture loop locking device

A strap assembly for surgical repair of split portions of tissue to retain the tissue portion in adjacent contacting relation during healing, which includes an elongated strap member and a buckle member for securing the strap member in a looped tensioned condition about the tissue portions. The buckle member is fabricated from a bioabsorbable material selected from the group consisting of polymers or copolymers of glycolide, lactide, trimethylene carbonate, lactone, dioxanone, and caprolactone. The preferred buckle member includes a housing member defining a longitudinal channel therethrough for reception of the strap member and a wedging member insertable within the longitudinal channel of the housing member to securely wedge the strap member against at least one bearing surface of the housing member.
