摘要:
Disclosed herein are implantable medical device, and in particular, vascular stent having a biocompatible scaffold seeded with endothelial cells. The stent can provide structural support to maintain the openness of a vessel lumen following angioplasty while the biological scaffold seeded with endothelial cells can provide a new, healthy blood vessel wall.
摘要:
A movable-core guidewire including a proximal portion and a distal portion. The proximal portion includes a proximal hollow tube. The distal portion includes a coil coupled to the proximal hollow tube and an elastomeric distal tube disposed within the coil. A core wire is disposed within the hypotube. The core wire is movable between a distal position wherein a portion of the core wire is disposed in the distal tube and a proximal portion wherein the core wire is removed from the distal tube. A method is also disclosed for advancing the guidewire to the treatment site.
摘要:
A catheter and guide wire exchange system including a catheter that has a guide wire lumen with a guide way extending along a length of the proximal shaft. A guide member is slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. A transition section joins the trilumen proximal shaft to a coaxial distal shaft.
摘要:
A package is provided for a catheter which comprises an elongate tube, having a proximal end and a distal end, for receiving a catheter shaft. The proximal end includes a sleeve element sized to accommodate one or more catheter shaft accessories located on the proximal end of the catheter, and a retainer portion for releasably retaining the catheter and catheter shaft accessories. The retainer portion is engageable with the sleeve element and is axially slidable relative thereto, between a storage state in which the retainer portion and the retained catheter shaft accessories are located substantially within the sleeve element and a usable state in which the retainer portion and the retained catheter shaft accessories are withdrawn from the sleeve element.
摘要:
A drug delivery device comprising an elongate flexible tube having a proximal end and a distal end, the elongate flexible tube being adapted to be slidably movable in a lumen of a catheter and guide wire exchange System; the elongate flexible tube having a lumen extending therethrough, the lumen of the tube being open at the proximal end and distal end and the lumen being adapted to receive liquid under pressure; the drug delivery device also comprising means for engaging the drug delivery device with the catheter and guide wire exchange System, whereby, in use, the drug delivery device is in fluid communication with the catheter and guide wire exchange System and a medication in liquid form is delivered from a reservoir through the elongate flexible tube to the distal end thereof for delivery of the medication to a desired site.
摘要:
An assembly for packaging a catheter includes flexible tubing capable of being coiled, and tubular retainer having a passageway extending therethrough. The tubular retainer includes a distal section for coupling to a proximal end of the tubing. A proximal end of the tubular retainer includes an opening for receiving a luer of the catheter assembly. A keyway is provided at a proximal end of the tubular retainer, the keyway being adapted to receive an inflation port of the luer. The keyway may include a snap point at a proximal end thereof, wherein the snap point is dimensioned such that a force is required to pass the inflation port past the snap point, thereby resulting in a snap fit. The keyway may include an entry portion beginning at the proximal end of the tubular retainer, and a nose portion disposed distal of the entry portion, with a snap point disposed therebetween. Depending on the length of the entry portion, a portion of the luer may be protected by the tubular retainer. The snap point provides a snap fit for the luer within the tubular retainer.
摘要:
A vascular treatment device delivery system includes an elongated protective sheath having a distal end and a proximal end, a delivery catheter disposed within an axial lumen of the elongated protective sheath, and a luer fitting operably connected to a proximal end of the delivery catheter. The system further includes a sealable container attached to the proximal end of the protective sheath, the sealable container surrounding the luer fitting and a sterility barrier attached to a portion of the sealable container.
