摘要: A radially expandable stent for implantation within a body lumen having a generally cylindrical body with open proximal and distal ends, the cylindrical body comprising a plurality of metal elements joined to allow flexing of the cylindrical body along the longitudinal axis of the body whereby the stent can conform to a curved body lumen and a polymeric film extending between the metal elements of the stent. The stent provides a biocompatible polymeric surface to contact and support a body lumen and also a flexible structure to allow the stent to conform closely to bends in a body lumen. The stent is especially useful for repairing an injury to blood vessels caused during angioplasty procedures.

摘要: A balloon catheter includes a sheath surrounding the balloon, the sheath having a longitudinal line of weakness and a drug-containing viscous matrix material intermediate between the balloon and the sheath such that when the balloon is positioned and inflated in the body lumen it causes the sheath to burst at the line of weakness and release viscous matrix material onto said body lumen. The device provides accurate placement of the dosage required at the location in need of treatment. The catheter is especially useful in balloon angioplasty procedures.

摘要: A model of arterial restenosis in domestic pigs using deep injury to the coronary arterial media resulting in extensive proliferative response. Metal wire coils are delivered percutaneously to the coronary arteries of pigs with an oversized, high pressure (14 atm) balloon and left in place for 5-6 weeks. During placement, the balloon expands the coils and delivers them securely within the arterial lumen causing fracture of the internal elastic lamina by the coil. An extensive proliferative response occurs and is associated with a lumenal area narrowing of at least 50% Immunohistochemical studies confirms the prominence of smooth muscle cells in the tissue. The histopathologic features of the proliferative response are identical to those observed in cases of restenosis post-angioplasty.This model closely mimics the proliferative portion of human restenosis both grossly and microscopically. It may thus be useful for understanding human restenosis and for testing therapies aimed at preventing restenosis after balloon angioplasty or other coronary interventional procedures.

摘要: Balloon catheters are prepared to include body affecting chemicals within microcapsules on the exterior of the balloon either alone or with a stent. The coating releases from the balloon when the balloon is inflated into contact with the lumen to be treated. The device provides accurate placement of the dosage required at the location in need of treatment. A sheath may be employed over the balloon and microcapsules to prevent the microcapsules from being rubbed off during delivery through a body lumen. The catheters are especially useful in balloon angioplasty procedures.

摘要: A stent and catheter device for temporary support of body lumens. The stent has a generally cylindrical continuous winding providing radial support from within a body lumen after implantation which can be implanted and removed by a balloon catheter. The stent is provided with an elongated lead attached to the proximal end of the winding and means at a proximal end of the lead and remote from the winding for uncoiling the winding to facilitate its removal in an opened condition with minimal tissue damage. This stent and catheter device is especially useful as a temporary supporting device for repairing damage to blood vessels caused during angioplasty procedures.
