Abstract: A tubular body for a medical device for insertion within a body passageway of a patient. The tubular body includes a tubular inner liner. A braided member is disposed along an outer surface of the liner. The braided member includes intersecting filaments and cells defined by the filaments. A securement mechanism, such as radiopaque solder, is disposed along a circumferential region of the braided member. The securement mechanism is attached to portions of the filaments and spans the cells that correspond to the circumferential region to inhibit relative movement of filament ends. An outer surface of the securement mechanism is sized to extend radially outward to a position up to an outer surface of the braided member to not add to the overall wall thickness of the tubular body. An outer jacket is positioned longitudinally around the braided member and connected to the inner liner.

Abstract: A sheath for deploying a medical device to a target site in the body of a patient. A tubular inner liner has a proximal portion, a distal portion, and an outer surface. An outer jacket has a proximal portion, a distal portion, and an inner surface. A reinforcing member is received within a length of the outer jacket. The outer jacket is positioned longitudinally around the inner liner and bonded to the outer surface of the liner. The reinforcing member, which may be a triaxial braid, or an encapsulated longitudinal reinforcing wire, extends along the outer jacket length and is configured for inhibiting elongation of the sheath upon deployment of the device.

Abstract: A fluid vessel is disclosed and includes a multiple disposable liners where each of the disposable liners includes a bottom floor and side walls extending away from and substantially perpendicular to the bottom floor such that a cavity is formed therein. The bottom floor includes an aperture defined therein and the bottom floor slopes in a plurality of directions to facilitate a movement of a fluid disposed in a top one of the plurality of disposable liners toward the aperture.

Abstract: A spring action medical device includes a spring that may propel a hammer component in a distal direction when the spring is released from a loaded state. When propelled forward by the spring, the hammer component makes contact with a distal tip of the medical device. The distal tip may then transfer a force to an external object, such as an occlusion in a body lumen.

Abstract: Certain aspects of the present invention provide devices for occluding vascular vessels. In some preferred forms, these devices are able to move from a first condition to a less compact, second condition in a vascular vessel so as to fully or partially prevent fluid from passing through the vessel. One such device includes a frame and a flexible sheet material. The device also includes an occluding material that is located in an interior region of the frame. The flexible sheet material and frame are associated with one another such that when the device is in the second condition in the vascular vessel, the sheet material is positioned in the vessel lumen so as to block fluid flow through the lumen.

Abstract: A closure device for closing a bodily passageway is provided. The device includes first and second frames and first and second crossbars. A sheet of biocompatible material is attached to one or more of the frames. The first crossbar extends across the first frame and has terminal crossbar ends connectively linked to separate sites on the first frame; the second crossbar is similarly linked to the second frame. The crossbars are attached to each other at a connection point, and they are each configured to bend away from the connection point when the closure device is deployed to close a bodily passageway. A method of making the closure device is provided, as well as a method for closing a bodily passageway using such a device. Further, a closure device assembly is provided, including a closure device, a delivery catheter housing, and a delivery release member.

Abstract: An anchor assembly is used with a medical device to engage the medical device against a body wall. The anchor assembly includes a pivotable anchor and a filament. The anchor is seated in a longitudinal orientation within a recessed channel located at the distal end of the medical device. Pulling on a proximal free end of the filament causes the anchor to pivot from a longitudinal orientation to a perpendicular orientation. The anchor in the perpendicular orientation engages against a body wall to immobilize the medical device.

Abstract: A medical wire guide may include a mandrel and a cannula disposed about a portion of the mandrel. A spring may be coupled with the mandrel. The spring may be placed in a loaded state in response to relative displacement between the mandrel and the cannula. Upon release from the loaded state, the spring is configured to bias the mandrel in a distal direction relative to the cannula.

Abstract: In at least one embodiment of the present invention, a retrieval device for entrapping and retaining a foreign object located in a body vessel for its extraction therefrom is provided. The device comprises a cage having a proximal end and a distal end and a longitudinal axis extending between the proximal and distal ends. The cage is radially expandable about the longitudinal axis to define an expanded state and to form an opening at the distal end for receiving the foreign object. The cage is collapsible to define a collapsed state and to retain the foreign object therein such that the foreign object is substantially aligned with the longitudinal axis. Extending proximally from the proximal end of the cage is a cable for retrieval of the device in the collapsed state.

Abstract: In at least one embodiment of the present invention, a drainage catheter for draining part of patient's body is provided. The catheter comprises an elongated member having a proximal portion extending to a distal portion and a lumen formed therethrough for fluid communication with the patient's body. The distal portion is formed of a polymer material having a first phase transition temperature and a second phase transition temperature that is less than the first phase transition temperature but is greater than about body temperature. The distal portion has a first configuration when at about body temperature for at least one of moving and anchoring the distal portion within the patient's body. The distal portion self-configures to a second configuration when at a temperature of at least the second phase transition temperature for retrieval of the distal portion from the patient's body.
