St. Jude Medical | Date: 2017-01-26

Insertion tool for a medical closure device for the sealing of an opening in a wall of a bodily organ, comprising a tamping force source adapted to deliver a first member to a position at the opening on one side of the wall subsequently to a second member being positioned at the opening on the opposite side of the wall. The tamping force source, which is energized prior to the tamping procedure, can be a spring, an elastic band or a pressurized gas container. A tamping spring can be compressed or extended upon loading. The tamping force source can be released in response to a manual operation or be triggered by retraction of the insertion tool.


A tissue puncture locator device includes an anchor assembly and a sealing member. The anchor assembly includes an anchor portion, a tube portion, and a filling member. The anchor portion is positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel. The anchor member has an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision. The filling member is retained in the tube portion and adapted for insertion from the tube portion into the anchor member to provide the expanded configuration, and adapted for retraction from the anchor member into the tube portion to provide the unexpanded configuration. The sealing member is configured for placement adjacent the vascular incision outside the vessel.

A tissue puncture access assembly that includes a sheath and a dilator. The sheath is operable between an expanded position with a first maximum outer diameter, and a collapsed position with a second maximum outer diameter that is less than the first maximum outer diameter. The dilator is insertable through the sheath and has a leading end positionable distal of a distal end of the sheath. The sheath is operated into the collapsed position prior to and during insertion with the dilator into a tissue puncture. The sheath is operated into the expanded position once positioned in the tissue puncture.

A prosthetic heart valve includes a stent having a collapsed condition and an expanded condition, the stent having a proximal end, a distal end and a plurality of commissure features. The heart valve further includes a valve assembly secured to the stent, the valve assembly including a cuff and a plurality of leaflets, each of the leaflets having a free edge having a first end and a second end, and a second edge secured to the cuff, the second edge having a first end, a second end, a first folded portion adjacent the first end, a second folded portion adjacent the second end, and an unfolded portion between the first and second folded portions. The first and second folded portions couple the leaflet to ones of the commissure features.


A medical device for the diagnosis or treatment of tissue in a body and method for fabricating the same are provided. The device includes comprises a first shaft and a second shaft. The first shaft includes a longitudinal axis, and the second shaft includes a second shaft axial end disposed within the first shaft. The second shaft is connected to the first shaft by a first nested lap joint formed between the first shaft and the second shaft.


The present invention pertains to multiple piece irrigated ablation electrode assemblies wherein the irrigation channels are insulated or separated from at least one temperature sensing mechanism within the distal portion of the electrode assembly. The present invention further pertains to methods for improved assembly and accurate measurement and control of the electrode temperatures while effectively irrigating the device and target areas.

A prosthetic heart valve (300) includes a collapsible and expandable stent (302) extending from an inflow end (330) to an outflow end (332) and a plurality of prosthetic valve leaflets (308) coupled to the stent. The prosthetic heart valve may also include a sealing ring (350) coupled to the inflow end of the stent, the sealing ring comprising a tube (400) extending circumferentially around the inflow end of the stent. The tube may be formed from a wire coiled into a repeating shape, such as a rectangle or a diamond, so that the tube is collapsible. A covering (500) may at least partially surround the tube. The sealing ring may include a first filler (620) positioned within the tube and/or a second filler (610) positioned between the tube and the covering.

A prosthetic heart valve (400, 500) may include a stent (450, 550) having an inflow end (410, 510) an outflow end (412, 512), a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly (460, 560) disposed within the stent and having a plurality of leaflets (462, 562). The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar (480, 490) and/or nonplanar (580, 590) annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks (790, 790, 890, 990, 1090, 1190) extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction to facilitate resheathing of the stent if desired.

A collapsible and expandable stent (320) extends in an axial direction from a proximal end to a distal end. The stent may include a plurality of first cells (324), each first cell having an open space defined by a first plurality of struts (322). The stent may further include a second cell (330) nested in the open space of one of the first cells, the second cell being defined by a second plurality of struts (330a-d). The stent may additionally include first and second connecting struts (332, 334) connecting the second cell to the one first cell. The second cell may be configured to pivot about the first and second connecting struts with respect to the one first cell. The pivoting may create a clearance space between the second cell and an outer perimeter of the stent in which portions of a native valve structure may be clamped.

A method of manufacturing a catheter shaft includes extruding an inner polymeric layer having a main lumen and two or more side lumens spaced about the main lumen; forming an outer polymeric layer about the inner polymeric layer; and inserting at least one elongate member, such as a wire, through each side lumen of the inner polymeric layer. The side lumens are less than about 1/5 the size of the main lumen. The method may further include the step of forming a braided layer between the inner polymeric layer and the outer polymeric layer. In an alternate embodiment, the method includes co-extruding an inner polymeric layer and a multi-lumen layer, the multi-lumen layer having two or more side lumens; forming an outer polymeric layer about the multi-lumen layer; and inserting at least one elongate member through each side lumen. Catheter assemblies made according to the described methods are also disclosed.
