Abstract: The present disclosure provides a method, system, and apparatus that adds rotational functionality to a conventional clot maceration device. The rotational functionality can be imparted by a wide variety of mechanical devices, such as by a hand operated rack and pinion type gear system or an electrically driven motor. An outer member (such as a catheter) of a declotting apparatus may be rotated while an inner member remains substantially fixed in position. The degree of rotation of the inner member may be between 60 and 180 degrees in a clockwise and counterclockwise rotation. In one embodiment, the rotating mechanism is coupled to a sliding and/or lateral mechanism to impart both lateral and rotational movement to the declotting apparatus. The deformable members of a basket or jacket of the declotting apparatus may form a helical structure and/or each comprise a bundled wire.

Abstract: This disclosure provides a self-expandable, woven stent in a variety of anatomical structures, including vessels in the arterial and venous system. The disclosed stent may comprise a body portion with a flange portion at one of its ends. The flange stent may also be a part of a modular stent assembly and/or utilized with other stents that are not flanged. In use, a first stent may be placed in a first vessel and a second stent (which may be a flanged stent) may be placed in a second vessel through a wall of the first stent. The flange stent may be created by bending shape memory wires around a template with a flanged portion or heat treating a substantially straight stent around a template with a flange or forming a stent with a tighter mesh on a portion of the stent over a substantially straight template.

Abstract: This disclosure provides a self-expandable, woven intravascular device for use as a stent (both straight and tapered) in a variety of anatomical structures, including vessels in the arterial and venous system. The stent provides enhanced structural modifications to conventional woven stents by varying the wire(s) utilized in the woven stent. The stent may be formed from shape memory metals such as nitinol. The stent may utilize multiple, parallel wires instead of a single wire, an increased number of wire pairs and/or pins to vary the mesh size, and/or a bundle of wires (e.g., a plurality of individual wires coupled together) instead of a single wire. The wire mesh may comprise two rows of wire or three rows of wire. The individual wires may each be twisted to provide an overall twist to the wire bundle. The bundle of wires may comprise different sized wires and wires of different materials.

Abstract: A method, system, and apparatus for retrieving, snaring, hooking, and/or grasping foreign bodies and retrieving them from the body of a patient. The retrieval device includes a catheter open at both ends such that one or more wires may extend at or near the distal end of the catheter and be used to retrieve the foreign body. A first, retrieval wire may be manipulated to form a loop or bend external of the catheter and around a portion of the foreign body. A second, looping wire may be manipulated to form a loop external of the catheter and around a portion of the retrieval wire, which may then be used to securely couple the foreign body and/or retrieval wire to the catheter for removal of the foreign body from the patient. The wires may extend from a side opening of the catheter and/or the end hole of the catheter.

Abstract: Self-expandable, woven intravascular devices for use as stents (both straight and tapered), filters (both temporary and permanent) and occluders for insertion and implantation into a variety of anatomical structures. The devices may be formed from shape memory metals such as nitinol. The devices may also be formed from biodegradable materials. Delivery systems for the devices include two hollow tubes that operate coaxially. A device is secured to the tubes prior to the implantation and delivery of the device by securing one end of the device to the outside of the inner tube and by securing the other end of the device to the outside of the outer tube. The stents may be partially or completely covered by graft materials, but may also be bare. The devices may be formed from a single wire. The devices may be formed by either hand or machine weaving.

Abstract: An occlusion method and apparatus. The occluder includes a elastically deformable members and a jacket. The elastically deformable members are secured in spaced relation and extend in arcuate conformation therebetween. The jacket covers at least a portion of the elastically deformable members.

Abstract: A coil-type vasoocclusion device (10) for establishing an embolus or vascular occlusion in a human or veterinary patient is adapted for introduction into the patient via a catheter (32). The device (10) first includes a coil (12) having proximal and distal coil ends (16,18) and a coil lumen (20). The device (10) also includes a core (22) disposed in at least part of the coil lumen (20), the core having proximal and distal core ends (24,26). Only one core end (24 or 26) is directly affixed to a respective end (16 or 18) of the coil (12); the other core end (26 or 24) is not directly connected to either end (16 or 18) of the coil (12). The core (22) is preferably nitinol in a superelastic state, being in other than its stress induced, martensitic condition. The device (10) can include a thrombogenic material (38) connected to or carried by the coil (12). The coil (12) is preferably adapted to achieve a suitable secondary shape (60) when deployed from the catheter (32).
