| 20080228261 | Intravascular stent with integrated link and ring strut - An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The stent includes a plurality of rings connected by links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since links are integrally formed from a portion of the struts forming the rings. The stent is constructed so that the cylindrical rings are very close together in order to provide maximum scaffolding, and if the stent has a drug coating, to provide a uniform drug delivery over the length of the stent. The connecting links are integrally formed from a portion of the struts forming the rings so that the links can have a maximum length thereby providing increased longitudinal flexibility of the stent. | 09-18-2008 |
| 20080269868 | STENT DELIVERY CATHETER SYSTEM AND METHOD OF IMPLANTING A SELF-EXPANDING STENT WITH EMBOLIC PROTECTION - A catheter system and method for implanting an i such as a stent at a treatment site in a patient's body lumen. The catheter provides a complete system for stent delivery, dilatation, and delivery and/or recovery of an expandable device, such as an embolic protection device, adjacent to the treatment site in the body lumen. | 10-30-2008 |
| 20090099641 | DELIVERY SYSTEM FOR MEDICAL DEVICES - The invention is directed a delivery system for implantation a self-expanding medical device in a body which includes a control handle and a catheter portion. The catheter portion includes an outer restraining member which covers the collapsed, medical device, an inner catheter member having a distal end including a region upon which the medical device is mounted, and an outer sheath which is removably attached to the control handle. The outer sheath creates a conduit for the catheter portion to prevent the inner catheter member from moving axially when the outer restraining member is retracted. The control handle has a rotatable thumbwheel to actuate a retraction mechanism attached to the proximal end of the outer restraining member which moves the restraining member in a proximal direction to deploy the medical device. | 04-16-2009 |
| 20100125322 | STENT DELIVERY CATHETER SYSTEM WITH HIGH TENSILE STENGTH - A stent delivery catheter system having a reinforcing tether member secured to the catheter such that the catheter is provided with an improved combination of an enhanced tensile strength together with other catheter performance characteristics such as low profile and high flexibility. | 05-20-2010 |
| 20100145431 | DELIVERY SYSTEM FOR MEDICAL DEVICES - The invention is directed a delivery system for implantation a self-expanding medical device in a body which includes a control handle and a catheter portion. The catheter portion includes an outer restraining member which covers the collapsed, medical device, an inner catheter member having a distal end including a region upon which the medical device is mounted, and an outer sheath which is removably attached to the control handle. The outer sheath creates a conduit for the catheter portion to prevent the inner catheter member from moving axially when the outer restraining member is retracted. The control handle has a rotatable thumbwheel to actuate a retraction mechanism attached to the proximal end of the outer restraining member which moves the restraining member in a proximal direction to deploy the medical device. | 06-10-2010 |
| 20100145433 | ENDOPROSTHESES FOR DEPLOYMENT IN A BODY LUMEN - Example embodiments include an endoprosthesis that has a first annular segment that is radially expandable and a second annular segment that is also radially expandable. An axial segment, which includes one or more struts, is operatively associated with the first annular segment and the second annular segment to maintain a specified distance between the first annular segment and the second annular segment. | 06-10-2010 |
| 20100193485 | METHODS AND SYSTEMS FOR LASER CUTTING AND PROCESSING TUBING TO MAKE MEDICAL DEVICES - Methods for making devices include providing a tubular member to be formed into a device, placing a removable sacrificial block material in the lumen of the tubular member and laser cutting the tubular member. A doping material can be added to the melted portion of the tubular member to promote the formation of brittle slag. A fixture can be used to hold a cut workpiece in order to ream sacrificial material from the surface of the workpiece. Pressurized gas can be supplied to the inner lumen of the tubular member to cause slag to form on the outside surface, rather than the inner surface, of the tubular member. A tubular member made from nickel-titanium alloy can be tightly adhered to a sacrificial sleeve utilizing the phase changes associated with nickel-titanium. A rotating mandrel can be placed within the lumen of the tubular member during laser cutting. A mandrel which includes an enlarged diameter section causes the workpiece to expand slightly within its elastic deformation range to dislodge islands from the workpiece. Such a mandrel could be formed from a tubular member which has a central lumen that can be used to deliver a pressurized medium to “blast” islands from the workpiece. | 08-05-2010 |
