Abstract: Apparatus for positioning of a medical device in body tissue includes an angle indexer which mates in at least two positions with an index-key attached to the medical device. The indexer may be hand held or otherwise secured to a separate device, such as an introducer cannula, with the medical device being rotatable relative to the indexer.

Abstract: Embolic coils, and related components, systems, and methods, are disclosed.

Abstract: An endoluminal device for affixation to a wall of a body lumen having a neck region defined by a relatively narrow width and a shoulder region that diverges from the neck region to a relatively wider width. The device comprises a bulbous portion having a shoulder portion with a diameter profile that conforms to the shoulder region of the lumen, and a converging diameter portion sized not to conform to the body lumen diameter profile. In some embodiments, a plurality of affixation members in an area of the device that typically extends from a distal end of the device through the shoulder portion. In one embodiment, the device comprises an endograft for repair of an aneurysm, such as an abdominal aortic aneurysm (AAA).

Abstract: The present invention includes an introducer sheath. The sheath may comprise a first proximal elongated section having a first outer diameter and a first inner diameter, and a main body elongated section having a second inner diameter and a second outer diameter, wherein the second outer diameter is larger than the first outer diameter. The sheath may further include a distal section having an outer wall that tapers from the second outer diameter of the main body elongated section to a smaller distal outer diameter.

Abstract: A system for treating tissue includes a probe assembly having a cannula, a shaft, and one or more needle electrodes. The shaft has a distal end, a proximal end, and a lumen extending between the distal and proximal ends of the shaft, and is slidable within the lumen of the cannula. Each needle electrode has a lumen that may be placed in communication with a port at a proximal end of the probe assembly, and is configured to deliver an occlusive element to a site. The system may further include an embolization actuator for delivering the occlusive element. A method of treating tissue includes placing an electrode at a site of a treatment region, occluding at least a part of a vessel located adjacent the site by delivering an occlusion element from an electrode, and delivering ablation energy to the site while the vessel is at least partially occluded.

Abstract: A device for introducing an embolic coil into a catheter comprises an elongated body defining a longitudinal passage extending therethrough from a first opening at a proximal end thereof to a second opening at a distal end thereof, the elongated body being including a mating portion for conforming to a size and shape of an opening in a hub of a catheter to mate therewith and an embolic coil introducer sheath including a coil receiving lumen extending therethrough, a distal tip of the introducer sheath being dimensioned to be received within a proximal end of the longitudinal passage. Similarly, a method of implanting an embolic coil, comprises inserting a stabilizer into a catheter hub so that a flexible mating portion substantially conforms to a shape of an inner surface of the hub wherein the stabilizer includes a passage extending therethrough from a proximal opening to a distal opening thereof.

Abstract: An embolic coil comprises an elongated core element formed of a shape memory material treated to define a memorized secondary coil shape and an elongated outer element wound around the elongated core element to define a primary coil shape of the embolic coil. A method of forming an embolic coil, comprises the steps of imparting a memorized shape to a core element formed of a shape memory material, wherein the memorized shape defines a secondary coil of the embolic coil and straightening the core element in combination with the steps of winding an elongated outer element around the straightened core element to form a primary coil of the embolic coil and releasing the straightened core element when the device has been positioned at a deployment location to form the secondary coil of the embolic coil.
