    摘要: The present invention utilizes a balloon with three or more folds to more evenly distribute the frictional forces on the inside of a stent during stent deployment thus improving the uniformity of stent cell expansion. Ideally one would like to have the same number of balloon folds as the number of stent cells distributed circumferentially around the stent. Matching the number of balloon folds to the number of cells of each cylindrical segment of the stent provides better size uniformity for the stent cells after they are expanded against the wall or other vessel within a human body.

    摘要: The present invention is a stent delivery catheter system for placing a stent within a stenosis in a vessel of a human body. The stent delivery catheter system utilizes a slideable sheath with a thin-walled distal portion that is situated coaxially over a stent that is placed onto a balloon located at the distal portion of a balloon angioplasty catheter. The distal end of a central portion of the sheath has an interior shoulder which is capable of exerting a distally directed push force on the balloon angioplasty catheter at a point that is just proximal to the stent. This push force is then transferred through the non-deployed stent to a gradually tapered, highly flexible, lubricity coated distal tip of the balloon angioplasty catheter. The structure of a continuous outer surface extending backward from the distal tip and onto the distal section of the sheath, plus the lubricity coating of the outer surfaces of the distal tip and the sheath, plus the increased stent delivery catheter system pushability provided by the sheath and the stent itself makes it possible for the stent delivery catheter system to be pushed through even very tight stenoses.

    摘要: This invention is directed to an integrated catheter system (60) including a stent catheter (65) and a balloon angioplasty catheter (20). The balloon angioplasty catheter (20) has an inflatable balloon (23) mounted near the catheter's distal end which is initially used for dilation of a vessel at a low balloon pressure to partially inflate the balloon (23). The stent catheter (65) contains a stent (15) within a stent containment cavity (69) and the stent (15) is displaced over the balloon (23). The stent (15) is held in place over the partially inflated balloon (23) and an outer tube (62) of the stent catheter (65) is pulled back. The stent (15) is deployed and the balloon (23) is reinflated to a higher pressure to embed the stent (15) into the wall of the vessel.

    摘要: The present invention is a method for using an improved guiding catheter that eliminates the need for an introducer sheath or a separate Tuohy-Borst "Y" adaptor, thus reducing the time and expense for performing artery opening procedures. Furthermore, the guiding catheter with straightening dilator as described herein allows the hole in the wall of the femoral artery in the groin, or even more advantageously, the radial artery in the arm to be approximately 2 French sizes smaller in diameter as compared to the hole that would be created if an introducer sheath is also used. The advantages of the present invention are accomplished by utilizing a guiding catheter with a dilator that has a stiffened and/or curved distal section that can be used to straighten the distal section of the guiding catheter as it is advanced through the arterial system. The guiding catheter plus dilator can then be used in a manner similar to an introducer sheath to percutaneously enter the artery by being advanced over a previously placed guide wire. Once the distal ends of the dilator and the guiding catheter are placed near the ostium of the coronary artery, the dilator and guide wire are withdrawn which allows the guiding catheter to assume its normal bent shape (e.g., a Judkin's bend) near its distal end. The cardiologist can then, by well known techniques, place the guiding catheter's distal end in the ostium of a coronary artery. Any of several well known procedures can then be performed including angiography, balloon angioplasty, atherectomy or stent placement.

    摘要: The present invention is a means for accessing blood vessels for the insertion of a guide wire while preventing the free release of blood. Specifically, a hollow, thin-walled metal tube typically having a sharp point at its distal end is joined at its proximal end to a transparent viewing section. The viewing section has a distal narrow lumen and a proximal chamber which has a cap at its proximal end. The cap encloses a pressure sealing means through which a guide wire can be passed. After the distal end of the metal tube is placed in an artery, blood will rush through the metal tube and into the viewing section. The air in the air-tight proximal chamber will alternatively be compressed between diastolic and systolic blood pressure. Feedback to the operator that the distal end of the metal tube is properly placed within an artery can be achieved by observing the reciprocating pulsatile motion of the blood column within the distal narrow lumen of the viewing section. When the proper pulsatile motion is observed, a guide wire can be passed through the sealing means in the cap, through the viewing section, through the metal tube and finally the guide wire will enter the lumen of the artery.

    摘要: The present invention is a uniquely shaped divided bowl that has two separated sections: 1) a cereal section, and 2) a milk and fruit section. These sections are approximately the same size. The consumer places the dry cereal into the cereal section and then places milk and fruit into the milk and fruit section. It should be understood that the consumer might chose to have only milk in the milk and fruit section. An important feature of the design of the milk and fruit section is a groove at its bottom surface into which the last of the milk and fruit goes so that the last bites can be consumed without titling the bowl.

    摘要: Disclosed is a system for placing an elongated permanent magnet into a volume of tissue within a human body that is suspected of being cancerous. The magnet's position is then detected by a magnet locating system that is used by a surgeon to find and remove the suspected tissue volume including a margin of tissue to assure that any and all cancer cells have been excised. The magnet locating system includes a wireless probe that sends a signal to a range indication device that indicates the range from the end of the probe to the magnet implanted in the human body. This indication of distance to the magnet is preferably accomplished by an audio signal or a visual display.

    摘要: Disclosed is a check valve for placement near the distal end of a catheter. A continuously smooth outer surface for the catheter with check valve system assures that there is no propensity for a blood clot to form in cracks on the system's outer surface. The check valve is a formed from a low durometer, highly elastic, elastomer cylindrical tube that is shrunk into a cylindrical groove that would typically be located near the catheter's distal end. When pressurized fluid is injected through the catheter, the cylinder that is placed over one or more holes in the cylindrical groove in the catheter is forced to expand radially outward which allows the fluid to be injected into the blood vessel. When the pressure is removed, the elastomer tube retracts to its normal position which position tightly covers the holes thereby preventing any blood from entering the catheter.

    摘要: Disclosed is a stent delivery system consisting of a stent delivery catheter, a guide wire over which the stent delivery catheter is advanced and a balloon angioplasty catheter that is placed over the guide wire and within the stent delivery catheter. The stent delivery catheter is an elongated cylindrical tube with a radioisotope stent placed at a distal section of the tube. Just proximal and just distal to the stent there is a proximal radioactive marker band and a distal radioactive marker band each of which are fixedly attached to the delivery catheter. After the stent has been properly positioned at the site of a vascular blockage such as an arterial stenosis, a balloon angioplasty catheter can be advanced over the guide wire and inside the delivery catheter. The balloon at a distal section of the balloon angioplasty catheter is then inflated which expands the stent and both radioactive marker bands radially outward against the wall of the blood vessel. By the use of this device, the regions of the vessel wall that are just proximal and just distal to the edges of the stent are given a sufficient dose of radiation so that the cells in that region become incapable of producing growth factor. By this method, the edge effect that is frequently encountered with a radioisotope stent is avoided.
