There is disclosed, among other things, embodiments of a biopsy needle for taking a full core sample through soft tissue. In the illustrated embodiments, the needle includes a single monolithic tubular member having a notch cut part-way through a distal portion of the tubular member to form an arch-shaped finger. At least a portion of the finger is bent toward the notch and into the lumen of the tubular member. Methods for using these embodiments are also described.

Rotating full-core biopsy needle

A hemodialysis catheter with a plurality of umbrella-like wire members covered with a film which works as a thrombus blocker and can easily and effectively remove the thrombus is disclosed. The hemodialysis catheter has a proximal lumen, the arterial lumen, and a distal lumen, the venous lumen. An elongate member is longitudinally put in either the proximal lumen or the distal lumen, or two elongate members in both lumens. A plurality of umbrella-like wire members are connected to the end of the elongate member. When the hemodialysis catheter is put in the vessel but not in use, the end of the lumen is capped off by the plurality of umbrella-like wire members covered with a film. When it is ready to use, the doctor can pull the elongate member which connects to the plurality of umbrella-like wire members out off the lumen inverting the plurality of umbrella-like wire members and clearing away any thrombus that has formed.

Among other things, there are disclosed embodiments of full-core biopsy needles having an outer needle component and a middle cannula through a lumen in the outer component, through which a mandrel may be placed. The outer component includes an internal boss that reduces its internal diameter, and the cannula includes fingers that extend distally. When the needle is inserted for biopsy, tissue enters the outer component and cannula. Moving the cannula forward causes the fingers to engage a surface of the internal boss, resulting in the fingers curving into the tissue. The fingers pinch the tissue while reducing or eliminating compression of the sample to provide an easier removal of the tissue from adjacent tissue, as well as providing a block or backstop keeping the tissue within the needle. Gaps are provided between the fingers to further reduce damage to the tissue sample.

Coaxial incisional full-core biopsy needle

A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with dilation elements that extend along a surface of a balloon. The dilation elements may comprise a coil and dilation wire. The coil and wire may be configured in various ways such that inflation of the balloon creates a concentration of forces along the dilating wires which are thereafter transmitted to stenosed regions of a vessel wall. The force exerted by the dilation elements against the stenosed region is sufficient to fracture plaque from the vessel wall.

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.

Spring action medical device

An occluding device for occlusion within a body vessel is disclosed. The device comprises an expandable frame having an occluding portion disposed within a closure area of the frame. An anchoring component is attached to the frame to engage the body vessel. A coupling is attached to the frame for repositioning the device.

Occluding device

A suture retention device is provided for retaining a suture. The device includes a body with a channel and two retention members within the channel. The retention members are movable between an unlocked state to a locked state in which the suture is restrained with respect to the body.

Suture retention device

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.

Vascular plugs

A multi-path catheter includes an elongate tubular member and a withdrawal pathway along which unfiltered fluid is withdrawn in a distal to proximal direction. The withdrawal pathway originates at a distal point and is at least partially defined by the elongate tubular member. The elongate tubular member also defines, at least partially, at least one infusion pathway along which filtered fluid is returned in a proximal to distal direction. The at least one infusion pathway extends distally beyond the withdrawal pathway. First and second legs of the elongate tubular member are positioned on opposing sides of the withdrawal pathway at the distal point, and the at least one infusion pathway is at least partially defined by one of the first and second legs. The first and second legs have outer walls that are unattached to one another at distal ends thereof.

Multi-path catheter

An endoluminal prosthesis that includes a support structure comprising a curvilinear portion having a first strut and a second strut that meet at an apex. Disposed on the support structure is an anchor with an anchor body and one or more barbs extending outwardly from the anchor body and where the anchor body comprises a multi-filar tube fits at least partially about, and conforms to the first strut, second strut, and the apex.
