Abstract: A bioabsorable stent is disclosed. The stent is made of a polymer and/or non-polymer material and has an elongated body having a proximate end, a distal end, and at least one open channel formed on the exterior surface of the elongated body to provide fluid communication between the proximal end and the distal end. Also disclosed is a bioabsorable stent having an elongated center rod having a proximate end and a distal end and a plurality of leaflets extending outward from the center rod and forming channels between two neighboring leaflets to provide fluid communication between the proximal end and the distal end.

Abstract: The present invention, in an exemplary embodiment, provides a delivery system and novel handle configuration for the delivery system that facilitates repeatable placement of implantable devices. In particular, in optical embodiments, the handle allows for the reversible coupling of scopes directly to the handle to enhance physician control during placement. The delivery system also allows for one-handed manipulation as finger action can be used to engage and disengage the scope as well as actuate the extent of implantable device deployment. Exemplary delivery systems are flexible, durable and/or assure proper installation of one or more implantable devices in a single procedure. Moreover, the preferred embodiments of the delivery system provides for the reloading of the delivery device with additional implantable devices for additional interventional procedures, resulting in a substantially reusable delivery device.

Abstract: The invention is relative to a stent with a tubular support frame consisting of axially successively following, interconnected annular segments which support frame is surrounded on its outside by a thread. The thread ends are guided via a deflection from the outside into support frame, where they are coupled by a connector consisting of a material visible in x-rays. Deflection is realized by two deflection elements in the form of eyelets provided on annular segments. Deflection elements are arranged on the circumference of support frame at an interval from one another and are provided on end-side annular segments, viewed in longitudinal direction of the stent.

Abstract: A lumen measuring device generally includes a central member dimensioned to extend into a lumen and an elongate outer member having a flexible region configured to flex outward from the central member in response to retraction of the central member. In measuring a lumen, the flexible region is caused to contact the lumen. The lumen may be contacted by linear segments that hinge or by members that bow arcuately. A polygon, such as a triangle, may be defined by portions of the outer member and the central member. A handle assembly may be provided by which the disposition of the central member relative to the outer member may be adjusted. Indicators may be defined by the central member and outer member by which the disposition of the central member and by which the diameter of a lumen may be determined.

Abstract: A delivery device for positioning and deploying an implantable device within a lumen is provided. The device includes a longitudinal outer tube having proximal and distal ends, wherein the implantable device is positioned proximate to the distal end of the outer tube. The device also includes a longitudinal inner tube slidably disposed within the outer tube and having proximal and distal ends, wherein at least a portion of the distal end of the inner tube is configured to underlie at least a portion of a proximal end of the implantable device. The distal end of the inner tube is located proximally of the distal end of the outer tube to define a gap for accommodating at least a portion of the implantable device. A mechanism is coupled to the inner and/or outer tubes and is operable to deploy the implantable device within the lumen.

Abstract: A delivery device for positioning and deploying an implantable device within a lumen is provided. The device includes an inner tube positioned within an outer tube and capable of sliding therein, wherein the inner and outer tubes have proximal and distal ends. A side opening is defined in each of the inner and outer tubes, wherein each side opening is defined proximate to the implantable device and is capable of substantially aligning with the other side opening. The device includes an optical device capable of viewing at least a portion of the lumen prior to deploying the implantable device when the side openings are aligned with each other. A mechanism is coupled to at least one of the inner and outer tubes and is operable to deploy the implantable device within the lumen.

Abstract: The present invention, in an exemplary embodiment, provides a stent deployment apparatus comprising excellent safety and stent placement and deployment features. An exemplary stent deployment apparatus in accordance with the present invention can facilitate the precise delivery of stents in a safe and repeatable fashion. In particular, a preferred deployment apparatus allows the physician to concentrate on correct placement without having to estimate extent of deployment by providing a physical safety mechanism that limits deployment to the critical deployment point. Moreover, to exceed this threshold, an audible and/or tactile indicator informs the physician that she can no longer retract the stent beyond this point. The stent deployment apparatus guidewire may also be extended rather than retracting the outer catheter to deliver the stent.

Abstract: The present invention provides a lumen measuring device and method that allows the user to calculate the exact length and diameter of a suitable interventional prosthesis as well as the height and length of stenosis during the same exploratory procedure.
