An assembly including a deployment device for deploying a stent device into an aorta of a patient is provided. The deployment device includes a rod translatable within an aorta of a patient and a first release wire configured for releasing one or more radially constraining members, wherein the radially constraining members are configured to constrain a diameter of the stent device. The stent device is at least partially permeable and engaged with the deployment device in an initial configuration, wherein a diameter and a length of the stent device in a deployed configuration can be altered by axial translation of the rod and releasing one or more of the radially constraining members by translation of the first lease wire. A related method is also disclosed.

A method of deploying a stent device into an aorta of a patient includes positioning a distal portion of the stent device at least beyond the left subclavian artery into the descending aorta by axially translating a distal end of a rod of a deployment device into the aorta. The stent device is engaged with the deployment device in an initial configuration about the rod. The axial translation occurs in a direction extending from the aortic arch into the descending aorta. The stent device further includes a stent portion in fluid engagement with the distal portion. The stent portion and the distal portion define an uncovered open cell surface. The stent device further includes a proximal portion in fluid engagement with the stent portion. A collar is defined at a terminal end of the proximal portion.

The introducer sheath can be loaded onto a vasoocclusive device after removal of the vasoocclusive device from a microcatheter, to permit the vasoocclusive embolic coil assembly to be used again during a clinical procedure. The sheath includes a hollow, elongated tubular member with a longitudinal slot formed in the upper wall of the elongated tubular member and extending along the length of elongated tubular member. The upper wall of the elongated tubular member adjacent to the slot has an angled configuration to accept the vasoocclusive device. The sheath may include wing members extending outwardly from the angled configuration on the outside surface of the hollow, elongated tubular member to facilitate insertion of the vasoocclusive device into the sheath. The elongated tubular member may also consist of a segment with no slot attached to a flexible pusher member to facilitate initiation of loading of the vasoocclusive device into the sheath.

A vasoocclusive coil is reinforced with a stretch resistant member to improve safety during retraction of the coil. The stretch resistant member is fixedly attached at one end to the vasoocclusive coil, and the other end of the stretch resistant member is detachably mounted to an elongated pusher member to allow for placement and release of the vasoocclusive coil within the patient's vasculature. The stretch resistant member may be formed from a therapeutic and/or bioactive non-metallic material to enhance the therapeutic properties of the vasoocclusive coil.

Apparatus and methods for percutaneously performing myocardial revascularization are provided using a catheter having an end region that is directable to contact a patient's endocardium at a plurality of positions. A cutting head is disposed within a lumen of the catheter and coupled to a drive tube that rotates and reciprocates the drive shaft. One or more stabilizing elements are disposed on the distal end to retain the catheter in position when the cutting head is actuated. The cutting head and drive tube include a lumen through which severed tissue is aspirated. Mechanisms and methods are provided for providing the operator with information to assess the desirability of treating a proposed site. Mechanisms also are provided for controlling the maximum extension of the cutting head beyond a distal endface of the catheter, independent of the degree of tortuosity imposed on the catheter.

Apparatus for percutaneously performing myocardial revascularization having means for sensing tissue parameters and method of use

An implantable vascular prosthesis is provided for use in a wide range of applications wherein at least first and second helical sections having alternating directions of rotation are coupled to one another. The prosthesis is configured to conform to a vessel wall without substantially remodeling the vessel, and permits accurate deployment in a vessel without shifting or foreshortening.

Vascular prosthesis and methods of use

The vasoocclusive device for use in interventional therapy and vascular surgery adapted to be inserted into a portion of a vasculature, includes a vasoocclusive coil disposed about an inner reinforcement coil wherein said vasoocclusive coil is helically wound and the inner reinforcement coil forms a reverse helical winding opposite the vasoocclusive coil winding, thereby forming a biplex wound coil. The vasoocclusive device biplex winding provides improved mechanical properties to the device. An inner reinforcement stretch resistant member attached within the biplex windings limits coil stretchability.

A catheter assembly includes a catheter, including an inner member and a sheath, extending from a handle. The handle includes a housing, a braking assembly, a carriage and a carriage driver. The braking assembly comprises a braking element within the housing interior and a braking element rotator. The carriage comprises at least one carriage braking surface engaging the braking element. The carriage driver, such as a spring, biases the carriage towards the proximal end of the handle. The inner member has a proximal end secured to the housing. The sheath has a proximal end secured to the carriage. Rotating the braking element causes the carriage to move proximally as the carriage braking surface slides along the braking element. This causes the sheath to move proximally relative to the inner member.
