An apparatus for deploying and retrieving a self-expanding intravascular stent includes an intravascular delivery wire and floating marker band movably retained over the intravascular stent delivery wire and releasably mounting the self-expanding intravascular stent. The floating marker band is movably retained to a fixed marker band, and a distance between the fixed marker band and the floating marker band is variable and self-adjusting. One or more struts of the self-expanding intravascular stent are releasably constrained between a catheter wall and one or more sides of the floating marker band.

A delivery mechanism for deploying a closure device includes several slidable members, a plunger, and attachments to tension members of the closure device. Deployment of the closure device includes controlling placement and expansion of the device within tissue using the tension members, the plunger, and the slidable members.

Closure medical device and delivery mechanism

A closure device for closing a puncture wound has a distal section that can be placed against the interior wall of a vessel and a proximal section that bunches in the tissue tract to close the wound.

The vasoocclusive apparatus can be used in a method of interventional therapy and vascular surgery by inserting the apparatus into a portion of a vasculature, for treatment of a body vessel such as an aneurysm in conjunction with a secondary vasoocclusive device to be placed within the vessel. The vasoocclusiveVasooclusiveapparatus includes a plurality of strut members connected together at a central hub that extend from a collapsed position to an expanded configuration to cross the neck of the aneurysm, dividing the neck into smaller openings, allowing the deployment of the secondary vasoocclusive device within the aneurysm but preventing migration of the secondary vasoocclusive device from the aneurysm. The strut members can be made from a twisted cable of strands of a superelastic material, such as a shape memory nickel titanium alloy, with at least one radiopaque strand. A shape memory collar is provided for detachably mounting the vasoocclusive apparatus to a pusher member and for detaching the vasoocclusive apparatus for deployment when a desired placement within an aneurysm to be treated and out of a parent vessel is achieved.

A closure device for closing a puncture wound has a distal section that can be placed against the interior wall of a vessel and a proximal section that bunches in the tissue tract to close the wound. One variation of the device provides for removing the distal section from the vessel so that it resides also in the tissue tract after the proximal section has been securely bunched and lodged within the tissue tract in order to provide unobstructed fluid flow in the vessel.

An extraction device for the removal of clots and foreign bodies from vasculature. The extractor device is connected to an elongate mandrel and is located within a longitudinally extending lumen defined by a catheter. A clot or foreign material extracted from a vessel by moving the extraction device and catheter proximally until the clot or foreign material does not perfuse a critical organ.

A vasoocclusive helical coil having a proximal end that carries a coupling member for attaching the coil to the distal end of a wire and a proximal winding that has a smaller diameter than adjacent windings whereby the proximal end of the coil is positioned radially inwardly of the main body of the coil.

This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm in the vasculature. In general, it is a device used to stabilize the presence of vaso-occlusive devices (such as helically wound coils) in the aneurysm. The device preferably is delivered by a core wire which terminates in an electrolytically severable joint. The core wire will often be insulated. The retainer assembly itself is also attached to the electrolytic joint and typically has a number of array elements which are intended to be resident within the aneurysm after the device is deployed from the distal end of a catheter. After deployment of this retainer, the aneurysm is at least partially filled with a vaso-occlusive device such as helically wound coils.

This invention is a surgical device. It is a composite guidewire for use in a catheter and is used for accessing a targeted site in a lumen system of a patient's body. The composite guidewire assembly is especially useful for accessing peripheral or soft tissue targets. The invention includes multi-section guidewire assemblies having (at least) super-elastic distal portions and super-elastic braided reinforcements along the mid or distal sections. A variation of the inventive guidewire includes the coating of the wire with a tie layer and then with a one or more lubricious polymers to enhance its suitability for use within catheters and with the interior of vascular lumen.

The invention provides methods, devices and systems for collecting breast ductal fluid comprising cellular material and other useful markers for analysis. The methods typically comprise access of at least one breast duct and collecting materials from that duct separate from all other ducts in the breast. The devices comprise ductal access devices that provide the opportunity to collect fluid from a single duct separate from all the other ducts in the breast. The systems employ the methods and devices that used together provide systems for analysis of a breast condition in a patient specific to accessed breast ducts. The methods, devices and systems are particularly useful for indentification of breast precancer or cancer in patient.

The occlusion balloon catheter includes an elongated tubular catheter body having a fluid lumen for inflation of an occlusion balloon detachably mounted to the catheter body by a tubular shape memory collar. The occlusion balloon includes a valve for sealing the occlusion balloon when it is inflated, and the collar of shape memory material clamps onto a stem of the valve. The shape memory collar can be heated by a fiber optic pusher member threaded through the catheter body to cause the collar to assume an enlarged configuration disconnecting the occlusion balloon. A method of detaching the occlusion balloon from the occlusion balloon catheter involves the steps of placing the occlusion balloon catheter within a guiding catheter, and placing the guiding catheter within the vasculature so that the distal opening of the guiding catheter extends into an aneurysm or other deformation to be treated. The fiber optic pusher is then used to expel the device into the aneurysm.
