摘要： An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.

摘要： A surgical instrument is configured to aid in performing a procedure of detaching an internal mammary artery (IMA) and the like, from the connecting tissues and side branch vessels which surround the artery in its native location, wherein the detaching procedure is preliminary to the performing of a coronary artery bypass grafting procedure and wherein the IMA is detached via a minimally invasive thoracotomy. To this end, an elongated slender rod includes a handle at its proximal end and an artery engaging loop, arc, fork configuration, or hook at its distal working end. Embodiments may incorporate electrosurgical capability or electrical insulation. A surgeon thus has means for harvesting an intact and undamaged graft vessel from its native location through a minimally invasive incision with enhanced speed, visibility, and freedom of motion.

摘要： Surgical instruments and methods for making substantially linear incisions, especially through the wall of vessels, such as arteries, specifically designed for coronary artery bypass graft procedures (CABG) on the beating heart. The invention is particularly useful to create the incision in the artery to which a bypass graft is sewn, typically the left anterior descending artery (LAD). The instruments allow incisions to be rapidly made, precisely measured, and cleanly formed so that a bypass graft can be rapidly sewn in place, without undue trauma to surrounding tissue and excessive loss of blood. In one embodiment, a hand-held instrument has a cutting edge formed on the interior edge of a curved blade fixed near the end of the instrument. The tip of the blade has a point for penetrating the vessel wall which may have several alternate shapes to facilitate penetration of the vessel wall while minimizing trauma to the surrounding tissue. In another embodiment the hand-held instrument includes a moveable member which creates an incision by engaging a cutting blade against a stop, cutting tissue therebetween, the stop including a pointed tip similar to the previous embodiment. In another embodiment, the instrument features a motion-canceling member which compensates for the movement of the target surface to be incised. This embodiment has a cutting blade which is manipulated from a handle which is isolated from the movement of the tissue containing or proximate to the target of the incision.

摘要： An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and support pads interconnected to the first blade. A torsional member is operably interconnected to the first blade and the spreader member and is used to vertically displace the first blade in either direction and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor interconnected to the blades is used to draw the soft tissue around an incision away from the surgeon's working area.

摘要： This invention is a microballoon tipped catheter. The catheter has a shaft which is of varying flexibility with the most flexible portion towards the distal tip. The balloon, located near the distal tip of the catheter, is typically of an elastic material, is quite flexible in its own right when deflated, and is quite small. The catheter shaft has a main lumen extending from the proximal end to the distal end so to allow the use of a guidewire in placing the catheter's distal tip in remote regions of the vasculature and for delivery of drugs, diagnostics, and other biologics to those regions. The catheter shaft has a wall that desirably is of a multilayer construction. The wall preferably includes an independent lumen, which may be formed from a small diameter tubing that is placed between layers of the wall, for the inflation and deflation of the microballoon. The inflation lumen proceeds from the proximal end of the catheter and terminates near the distal end of the catheter but within the microballoon. This catheter is especially useful in treating disease within the high pressure vessels of the brain with drugs or other therapeutic agents and permits temporary blockage of blood flow and thereby allow better absorption of those active agents.

摘要： A catheter for accessing a target site along a tortuous, small-vessel pathway. The catheter includes a flexible distal segment which is composed of a flexible polymer tube and a low-friction internal tubular surface. The surface allows the catheter to be advanced over sharp bends and small-diameter loops in a guidewire, in advancing the catheter along a small-vessel pathway. Various embodiments of the catheter are disclosed wherein the internal tubular surface of a distal portion of the catheter include a variety of different constructions and are comprised of a variety of different materials so as to best avoid the jamming, sticking or locking of the distal end or any part of the guidewire against the surface. Braided sleeve-like constructions, surfaces embedded with a plurality of small particles and surfaces comprised of various anti-friction materials are used in order to obtain the object of the invention.

摘要： A liner is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner is advanced through the narrowed region in a collapsed position. A stent is then advanced through the liner and expanded to open the narrowed region. The liner may also have an anchor, which expands an end of the liner before the stent is introduced.
