An intravascular stent and method for inhibiting restenosis, following vascular injury, is disclosed. The stent has an expandable, linked-filament body and a drug-release coating formed on the stent-body filaments, for contacting the vessel injury site when the stent is placed in-situ in an expanded condition. The coating releases, for a period of at least 4 weeks, a restenosis-inhibiting amount of a monocyclic triene immunosuppressive compound having an alkyl group substituent at carbon position 40 in the compound. The stent, when used to treat a vascular injury, gives good protection against clinical restenosis, even when the extent of vascular injury involves vessel overstretching by more than 30% diameter. Also disclosed is a stent having a drug-release coating composed of (i) 10 and 60 weight percent poly-d/-lactide polymer substrate and (ii) 40-90 weight percent of an anti-restenosis compound, and a polymer undercoat having a thickness of between 1-5 microns.

A small diameter delivery device capable of delivering a tissue loaded scaffold arthroscopically to a tissue defect or injury site without reducing the pressure at the injury site is provided. The scaffold delivery device of the present invention comprises a plunger system that includes two main components: an insertion tube and an insertion rod. The insertion tube has a flared proximal end for holding a tissue scaffold prior to delivery. An elongate, hollow body extends from the flared proximal end to a distal end of the insertion tube, and defines a passageway that extends through the body for delivery of the tissue scaffold. The insertion rod has an elongate body that extends into a handle at a proximal end and a tip at a distal end. The insertion rod is configured to be removably disposed within the insertion tube for sliding along the passageway to effect delivery of the tissue scaffold through the insertion tube.

A topical cooling compressive hemostasis wound healing device and methods thereof for affecting a percutaneous access site wound or an acute surgical wound. The device delivers and transports cooling to affect and control vasculature and musculoskeletal motions surrounding the injury site during the blood coagulation, hemostasis, and wound healing phases. The device comprises a viscoelastic and thermally conductive surface to deliver and transport an adjustable compressive pressure to resist outward blood flow, thus improving patient safety and clinical outcomes. The device is anatomically conforming and treats not only the specific injury site, but also its surrounding anatomical structures together as means to prevent unpredictable delayed hemostasis breach. The device provides comfort to the patient by allowing mobility upon wound healing, thus reducing back pain and strain resulting from being in constrained position for a prolonged period of time which is known to cause additional medical events. The device reduces pain, inflammation, swelling, and scar formation on the injury site of a patient and promotes hemostasis, sustains hemostasis, and improves overall wound healing quality.
