    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： 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： 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： The present disclosure generally provides a multiple balloon assembly used as part of the distal region of a medical device that is capable of delivering a therapeutic agent into a body vessel having bodily fluid. The multiple balloon assembly comprises an inner balloon and an outer balloon. The outer balloon further comprises a proximal taper region, a middle region, and a distal taper region. The inflation of the inner balloon causes the middle region of the outer balloon to contact the inner wall of the body vessel, thereby, occluding the flow of fluid through the body vessel. The proximal taper region and the distal taper region are configured such that they do not touch the inner wall of the body vessel. One of the distal taper and proximal taper regions has a plurality of apertures configured to allow for the therapeutic agent to be delivered into the body vessel at a predetermined rate. A medical device that incorporates the multiple balloon assembly of the present disclosure, as well as a method for using the medical device and multiple balloon assembly are further disclosed.
