A catheter assembly comprises a catheter having a distal end and a longitudinal axis, a stent disposed about the distal end of the catheter, and a stent protector. The stent protector has a stent covering portion disposed about the stent and a catheter engagement portion that removably engages the stent protector to the catheter assembly. The stent covering portion is disposed about the stent without substantially engaging the stent.

Stent protector design

Described herein are implantable medical devices for delivering a therapeutic agent to the body tissue of a patient, and methods for making such medical devices. In particular, the implantable medical devices, such as intravascular stents, have a coating which includes at least one coating composition and has an exposed abluminal surface and an exposed luminal surface or exposed side surface.

Coating for medical device having increased surface area

A stent assembly comprises a second stent body and a substantially tubular first stent body defining a first lumen and containing a side branch opening. In an undeployed state, the second stent body is at least partially comprised of rings having peaks and valleys at least some of the valleys of adjacent rings being interconnected by bridges. In an expanded state, the rings of the second stent body define a second lumen opening in fluid communication with the first lumen. The second lumen has superior body vessel coverage and is flexible enough to form an oblique angle relative to the longitudinal axis of the first stent body.

Connectors for bifurcated stent

A stent assembly comprises a proximal stent and a distal stent. Each stent has a tubular body defining a stent lumen and a circumference. A proximal flap extends from the distal end of the proximal stent and a distal flap extends from the proximal end of the distal stent. Each flap defines only a portion of the circumference. In an expanded state the proximal flap and the distal flap form a side branch support having a side branch support lumen. The side branch support lumen is in fluid communication with the stent lumen and has a longitudinal axis different from that of the stent lumen.

Crown stent assembly

A stent may comprise a plurality of serpentine bands connected by connector struts. The stent may further comprise a side branch cell having a plurality of outwardly deployable petals. Each serpentine band may have an approximate longitudinal axis. A portion of the serpentine bands may be flared in the unexpanded state, wherein a portion of the axis of each flared band is oriented helically about a portion of the stent. The bands may reorient during stent expansion, whereafter the axis of each band is oriented in a circumferential direction.

Bifurcation stent pattern

An endoprosthesis includes a brittle layer, e.g. a ceramic and an underlayer to accommodate dimensional changes as the endoprosthesis is flexed.

Deformable underlayer for stent

A bifurcated stent that uses turning segments to reduce the strain at regions which bend at extreme angles. The turning segments can be placed on side branch petals or on connectors connecting the petals to the stent body. Combining the turning segments with connectors of different length and tethers provides for a stent with high flexibility that can accommodate various shaped body vessels. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the problems of angularly strained side branch.
