Abstract
An intraluminal stent comprising fibrin is capable of reducing the incidence of restenosis at the site of vascular injury such as that produced by an angioplasty procedure.
Claims63
An intraluminal device comprising:
- (a) means for percutaneous, transluminal delivery of a stent into a body lumen and through the body lumen to a portion of the body lumen having a luminal restriction;
- (b) a stent attached to said delivery means, the stent having preformed fibrin thereon;
- and
- (c) means for expanding the stent and preformed fibrin thereon into contact with the body lumen.
A method for preventing restenosis in a body lumen treated to open a luminal restriction, the method comprising the steps of:
- (a) delivering a stent having preformed fibrin thereon percutaneously and transluminally into a body lumen and through the body lumen to the portion of the body lumen having the luminal restriction;
- and
- (b) expanding the stent and preformed fibrin thereon into contact with the body lumen.
An intraluminal device comprising:
- (a) means for percutaneous, transluminal delivery of a stent into a body lumen and through the body lumen to a portion of the body lumen having a luminal restriction;
- (b) a stent attached to said delivery means, the stent having preformed fibrin thereon, the preformed fibrin made with a coagulating protein in which residual coagulating protein has been neutralized;
- and
- (c) means for expanding the stent and preformed fibrin thereon into contact with the body lumen.
A method for preventing restenosis in a body lumen treated to open a luminal restriction, the method comprising the steps of:
- (a) delivering a stent having preformed fibrin thereon percutaneously and transluminally into a body lumen and through the body lumen to the portion of the body lumen having the luminal restriction, the preformed fibrin made with a coagulating protein in which residual coagulating protein has been neutralized;
- and
- (b) expanding the stent and preformed fibrin thereon into contact with the body lumen.
An intraluminal device comprising:
- (a) means for percutaneous, transluminal delivery of a stent into a body lumen and through the body lumen to a portion of the body lumen having a luminal restriction;
- (b) a stent attached to said delivery means, the stent having a preform of fibrin intermixed with at least one polymeric material thereon;
- and
- (c) means for expanding the stent and preform of fibrin and polymeric material thereon into contact with the body lumen.
A method for preventing restenosis in a portion of a body lumen treated to open a luminal restriction, the method comprising the steps of:
- (a) delivering a stent having a preform of fibrin intermixed with at least one polymeric material thereon percutaneously and transluminally into a body lumen and through the body lumen to the portion of the body lumen treated to open the luminal restriction;
- and
- (b) expanding the stent and the preform of fibrin thereon into contact with the body lumen.
