    摘要： A stent deployment device (110) is provided for deploying a stent in a lumen of a patient. The device can include a catheter (112), a first balloon (122) positioned near a distal end of the catheter and a second balloon (123) adjacent to the first balloon. Alternatively, the second balloon can be positioned over the first balloon. The device also includes an expandable stent (210) positioned over the first balloon and the second balloon. The first balloon comprises a semi-compliant material, a noncompliant material or a compliant material. Similarly, the second balloon comprises a semi-compliant material, a noncompliant material or a compliant material. The first balloon is expandable to a first diameter, while the second balloon can be expandable to a second diameter.

    摘要： A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

    摘要： An apparatus and method for inserting an article into a body opening. A radially expandable introducer sheath is delivered in a non-expanded condition into a body opening. A release mechanism releases the introducer sheath from the non-expanded condition into a condition that permits radial expansion of the introducer sheath upon introduction of a medical device through the sheath into the body opening. An optional handle having a circumferential opening may be provided for withdrawing the sheath from the body opening, while leaving the medical device in place.

    摘要： A medical device (10) includes a catheter shaft (11) including inner and outer catheter shafts (12 and 14), and an expandable balloon (18) carried by the catheter shaft (11). The balloon (18) is made from an irradiation cross-linked mixture of a polyamide elastomer and at least one additional cross-linking reactant. The polyamide elastomer can be a polyester amide, a polyether ester amide or a polyether amide, and is preferably a nylon block copolymer. The cross-linking reactant can be: (a) a difunctional material, (b) a trifunctional material, (c) a tetrafunctional material, or (d) an aromatic molecule containing at least two ring substituents, each of the ring substituents having labile hydrogens at a benzylic site therein. The cross-linking reactant can also be diallyl phthalate or meta-phenylene dimaleimide. Irradiation is carried out by exposure to an electron beam or to ultraviolet, X- or gamma radiation, preferably at a total fluence of about 0.5 to about 20 megarads. The amount of the cross-linking reactant is selected to avoid the formation of gelling during the process by which the balloon (18) is made, and the amount of the cross-linking agent and the irradiation fluence are selected to give the balloon a strength generally about equal to that which would be obtained by mere irradiation.
