An end-side anastomosis system including a fitting including a base for attachment to a graft, the base be configured to form a seal with an opening in a host vessel wall a leading petal having a cross-section with a radius of curvature approximating a radius of curvature of the host vessel, the leading petal being configured to dilate the host vessel wall opening while advancing the fitting through the opening and a rear petal, the rear petal being deflectable to be advanced through the host vessel opening.

Anastomosis systems

An end-side anastomosis system including a fitting comprising: a base for attachment to a graft, said base be configured to form a seal with an opening in a host vessel wall; a leading petal having a cross-section with a radius of curvature approximating a radius of curvature of the host vessel, said leading petal being configured to dilate the host vessel wall opening while advancing said fitting through the opening; and a rear petal, said rear petal being deflectable to be advanced through the host vessel opening.

A stent crimping apparatus for crimping a deformable radioactive stent onto a deployment device which includes a first jaw member defining a shielded first compression surface, and an opposed, second jaw member defining a shielded second compression surface oriented opposite the first compression surface. The first and second compression surfaces are adapted to collectively form an elongated guide bore formed for axial receipt of the deformable stent and the deployment device therein. To protect against exposure to the radioactive stent, a shield assembly is provided defining an opening into a bore therein which is formed and dimensioned for longitudinal receipt of the deformable stent in an uncrimped condition. A shield assembly defines an opening into the bore, and cooperates with the first and second jaw members to substantially prevent radioactive particles emitted by the radioactive stent from passing out of the crimping apparatus. An operating mechanism is operatively coupled to the first and second jaw members for selective movement between a loading condition and a crimping condition. In the loading condition, the uncrimped stent and the deployment device may be inserted through the opening and into the bore. In the crimping condition, the deformable stent is radially compressed onto the deployment device between the first and second compression surfaces.

Stent crimper apparatus with radiation shied

A variety of improved thermal mapping catheters are disclosed which are capable of sensing and mapping thermal variations within body vessels. In embodiments directed at vascular applications, the catheters are capable of detecting temperature variations in atherosclerotic plaque, on the atherosclerotic plaque surface, and on the arterial wall of aneurysms and other vascular lesions of the human vasculature. In one aspect of the invention, a combined thermal mapping and drug delivery catheter is provided. In this embodiment a plurality of thermal sensors are combined with at least one infusion port suitable for delivering therapeutic agents into a vessel. In some embodiments, at least some of the infusion ports are located between adjacent thermal sensors. The described catheters may be used in a variety of new applications and medical diagnostic and treatment techniques.

Thermography catheter

A radiation shield assembly (,) for a radioactive stent (,) mounted onto a deployment portion (,) of a delivery apparatus (,) including a relatively thin, elongated tube member (,) having a wall (,) defining a receiving passage (,) formed and dimensioned for axial receipt of the stent mounted onto the deployment portion therein to substantially prevent direct contact with the stent (,). A removal structure (,) cooperating with the wall (,) of the tube member (,) for longitudinal severing thereof to enable selective removal of the tube member from the delivery apparatus (,) for deployment use thereof.

Shield assembly with removable inner-tube apparatus for radioactive stents

A radiation shield assembly (30) for a radioactive stent (11) which includes a first shield member (31) having a first mating surface (32) and a second shield member (33) having an opposed second mating surface (35). When the two shield members are removably coupled to one another, the first mating surface (32) cooperates with the opposing second mating surface (35) to substantially radially enclose the stent (11) therebetween, and substantially prevent the direct passage of radioisotopes emitted from the stent radially out of the shield assembly (30).

Shield assembly for radioactive stents

A stent loading apparatus for loading a self-expanding radioactive stent into a bore of a deployment device in a compressed condition including a storage device defining an elongated first passage formed and dimensioned for sliding receipt of the stent therein. The first passage extends through the storage device and terminates at a stent transfer opening of a proximal coupling end thereof. A radiation shield defines an elongated second passage which terminates at a distal opening of a distal coupling end thereof. The distal coupling end of the radiation shield and the proximal coupling end of the storage device cooperate to align the distal opening of the shield in receiving communication with the stent transfer opening of the storage device. The second passage of the shield is formed and dimensioned for receipt of the deployment device therein in a manner positioning a mouth of the deployment device bore substantially adjacent the stent transfer opening of the storage device. Upon urging of the stent in a direction toward the shield, the radioactive stent may be slideably transferred from the first passage and into the mouth of the bore for retainment therein in the compressed condition.

Stent loading assembly for a self-expanding stent

A stent loading apparatus for loading a deformable stent onto a deployment device. The stent loading apparatus includes an elastic member defining a passage therein formed for longitudinal receipt of the deformable stent in an uncrimped condition. A first member includes a first compression region; and a second member includes a second compression region positioned substantially adjacent the first compression region at a first position. At this first position, the elastic member and the deformable stent in the uncrimped condition may be received between the opposed first and second compression regions. The first compression region and the second compression region are further configured to provide rolling support and compression of the elastic member during relative movement between the first position and a second position for rolling radial compression of the deformable stent onto the deployment device.

Cylindrical roller stent crimper apparatus with radiation shield

An intravascular catheter system capable of mapping thermal variations in the temperature of athrosclerotic plaque, on the athrosclerotic plaque surface, and in the arterial wall of aneurysms and other vascular lesions of the human vasculature is provided. The catheter system incorporates a plurality of thermal sensors fixedly attached along the catheters multi-lumen flexible tubular member which is adapted for insertion into the human body. Optionally, the thermal mapping catheter of the present invention is combined with other features such as intravascular ultrasound, and localized drug delivery, to provide integrated device functions.
