International Classification:

A61M 500

US Classification:

604 8, 604200, 604159

Abstract:

A shunt and method of use for maintaining distal blood flow during an arteriotomy procedure is disclosed. The shunt includes a first tubular member having a proximal end, a distal end, and a lumen therebetween. The proximal end has an opening in communication with the lumen, and the proximal opening is adapted to receive blood from a first region of an artery. The distal end has an opening in communication with the lumen, and the distal opening is adapted to release blood into a second region of the artery. The shunt includes a second tubular member having a proximal end, a distal end, and a lumen therebetween which either merges and communicates at its distal end with the lumen of the first tubular member, or rides separate and parallel to it. The shunt also includes a hemostatic valve attached to the proximal end of the second tubular member, the valve acting to prevent loss of blood from the lumen of the second tubular member and to permit the introduction of a medical device into the lumen of the second tubular member and into the artery. In use, the distal opening of the shunt is inserted into the second region of an artery and secured to the lumen of the artery.

International Classification:

A61M 2900

US Classification:

606200

Abstract:

An ablation catheter system for capturing and removing necrotic tissue and thrombi generated during an ablative procedure is disclosed. The catheter typically includes an elongate member, a filtration assembly disposed within the distal region, and an ablation instrument at the distal end. Alternatively, the ablation instrument is carried on the distal end of an ablation catheter, which is disposed within a lumen of the catheter system. The catheter may further include an aspiration port and lumen. Methods of using the devices in preventing distal embolization during ablative procedures are disclosed.

Abstract:

A method for carotid endarterectomy. A blood filter is positioned within a carotid artery downstream of an atheromatous plaque. The filter is expanded. The carotid artery is clamped upstream and downstream of the atheromatous plaque while the filter is expanded. An endarterectomy procedure is performed on the region of the carotid artery having the atheromatous plaque. The carotid artery is unclamped while the filter is expanded. In certain cases a shunt is positioned in a region of the carotid artery having the atheromatous plaque and secured to the shunt by clamping, the shunt comprising a tubular member having a proximal opening, a distal opening, and a lumen therebetween.

Abstract:

A medical device and related method of use for cutting tissue is described. The device includes an elongate tubular member having a proximal end, a distal end, and first and second lumens extending between the proximal and distal ends. The device further includes a first elongate arm having a third lumen extending distally from the first lumen and a second elongate arm having a fourth lumen extending distally from the second lumen. A cutting element extends from the third lumen of the first arm to the fourth lumen of the second arm, such that the cutting element is slidably disposed in at least one of the third and fourth lumens.

Abstract:

A stent delivery device has a handle and a sliding body, the sliding body is slidable with respect to the handle. The handle has a grip and a guide. The sliding body has at least two flange portions extending from the sliding body. The flange portions are offset from one another along the length of the sliding body. The operator can thereby deploy a relatively long stent by first gripping the nearest flange portion and pulling the sliding body toward the handle; subsequently, the operator can reposition his/or finger on the next-nearest flange portion and continue deployment of the stent by pulling the sliding body further toward the handle.
