A method and apparatus for the provision of a coating for application to a medical device results in a medical device having a bio-absorbable coating. The coating includes a bio-absorbable carrier component. In addition to the bio-absorbable carrier component, a therapeutic agent component and solvent can also be provided. The solvent is removed from the coating before the coating is applied to the medical device. The coated medical device is implantable in a patient to effect controlled delivery of the coating, including the therapeutic agent, to the patient.

An expandable cage used in conjunction with an embolic filtering device has a strut configuration including a proximal strut assembly coupled to a distal strut assembly. A filter can be attached to the distal strut assembly which has an inlet opening. The proximal strut assembly is “offset” from the distal strut assembly in that these proximal struts extend substantially along the vessel wall of the patient, rather than being “centered” in the body vessel when the cage is expanded in a body vessel. As a result, there is little cage structure directly in front of the opening of the filter, resulting in a virtually unobstructed opening for the filter.

A wound closure including a wound bridging portion that has sufficient dimensional stability to hold the wound edges in proper alignment, even in the face of substantial stretching of the wound closure as a whole, is disclosed. The wound closure is dimensionally stable directly over the wound. The remainder of the wound closure is preferably substantially more extensible and elastic than the wound bridging portion to improve conformability and adhesion of the wound closure to the patient. The wound closures may include opposing end portions of unequal lengths yielding an asymmetric shape that facilitates close placement of the wound closures along a wound.

An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The lengths and positioning of the first and second control arms of each half frame can be varied to create an expandable frame which conforms to the size and shape of the body vessel in which the filtering device is deployed. Additionally, the radius of the partial loops, along with the length of the arc of the partial loops, can be varied on each of the frames to create a composite filtering assembly that can easily adapt to the size and shape of the body vessel. Additionally, the control arms of the half frames can be disposed either proximally or distally of the composite loop to create a distinct filtering structure.

A self-expanding cage for use in conjunction with an embolic filtering device includes a circumferential member adapted to expand from an unexpanded position to a expanded position within the patient's body vessel. A proximal strut and distal strut are attached to the circumferential member to form the cage. A plurality of proximal and distal struts may be attached the circumferential member. Additionally, a second circumferential member can be attached to the first circumferential member. Each circumferential member can be connected by a single or a plurality of connecting struts. One embodiment of the cage utilizes a single wire to form to the cage. A delivery system attached to the single wire cage moves the cage and its associated filter element between the expanded and unexpanded positions through relative movement of the distal delivery system. This can be accomplished by either torquing the guide wire onto which the expandable cage is mounted or by longitudinally moving a tubular member which forms part of the delivery system longitudinally in relation to the guide wire.

A self-expanding basket for use in conjunction with an embolic filtering device has a proximal set of struts which are connected to a distal set of struts by a bending region which provides enhanced bending characteristics to the basket. The bending region can be formed by intermediate links which are extremely flexible and bendable to allow the basket to be delivered through tortuous anatomy. The intermediate links are extremely flexible and create a mechanical hinge-like connection between the proximal and distal strut assemblies. The basket thus is capable of substantial bending when being delivered through the patient's vasculature and will bend and conform to the patient's anatomy once positioned for filtering purposes. The intermediate links can also lengthen, when needed, when positioned in a curved vessel in the patient's vasculature, when needed. As a result, the basket will easily conform to a curved body vessel to maintain proper wall apposition of the filtering element with the wall of the body vessel.
