A guidewire (36) for a medical device is disclosed. The guidewire includes an elongate body (90), a proximal connector assembly (98), a corewire (52), and a sensor assembly (54). The body has an annular wall (94) that defines an interior lumen (96). The proximal connector assembly is coupled to the body and is configured for connection to a medical positioning system (20). The corewire extends through the lumen. The sensor assembly located on a distal end of the corewire is electrically connected to the proximal connector assembly. The sensor assembly is configured to generate an electrical signal indicative of a position of the sensor assembly in a reference coordinate system defined by the medical positioning system being electrically connected by a pair of conductors (74) and, an electrically insulating structure (76) that surrounds the corewire and insulates the corewire from the two pair of electrical conductors.


A medical device assembly (10) comprises a medical device (12) comprising a shaft (22) having proximal (24) and distal (26) end portions. The device further comprises a sensor (28) at the distal end portion of the shaft that comprises first (321) and second (322) leads extending therefrom to the proximal end portion (24) of the shaft. The device further comprises an electromechanical connector (30) having a plurality of pins (40) at a first end thereof. First (401) and second (402) of the pins are electrically connected to the first and second sensor leads, respectively, thereby forming a first partial magnetic loop between the first and second pins. The connector further comprises first and second jumpers (68) electrically connecting the first pin and third (403) pins, and second and fourth (404) pins, respectively, thereby forming a second partial magnetic loop. The partial magnetic loops are configured to combine with partial magnetic loops of a second connector (56), to which the first connector is mated, to form a pair of magnetic noise cancellation loops.

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 prosthetic heart valve for replacing a native valve includes a stent extending between a proximal end and a distal end and including a plurality of struts forming cells, the stent having a collapsed condition and an expanded condition. At least one runner is coupled a cell, the at least one runner being configured to transition from a first configuration to a second configuration when the stent moves from the collapsed condition to the expanded condition, the at least one runner projecting radially outwardly from the cell in the second configuration. A valve assembly is disposed within the stent, the valve assembly including a plurality of leaflets, a cuff at least partially disposed on a luminal surface of the stent, and a covering material disposed on an abluminal surface of the stent and covering the at least one runner in the second configuration.

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.

Improving quality of care has been given too little attention in health economic research in the past although it is the central goal of health care systems in Europe. The proposed ETN on Improving Quality of Care in Europe (IQCE) aims to address this gap and has the following aims: 1) Create new evidence and improve existing health economic research in the field of quality of care. Research gaps are addressed by empirical, theoretical and experimental approaches with a focus on innovative econometric methods using novel access to databases. 2) Establish a close link of the topical PhD projects to health policy and practice ensuring high relevance and practical applicability of results. Implementation of project results can potentially enhance performance of European health care systems. 3) Train PhD fellows to be experts in the field of quality of care and obtain excellent profiles for different career paths in health economic research or practice. 4) contribute to better coordination of currently fragmented health economic research in Europe. This will improve the competitive position of European health economic research. 5) serve as a model for joint doctorate programmes in health economics in Europe. This will drive the development of PhD programmes in health economics in Europe, which currently are scarce. To address these aims, the research programme consists of research clusters: (a) effectiveness & safety, (b) efficiency, (c) access & equitability, and (d) acceptability (WP2-5). Clusters also define secondments and joint research activities of one cluster. Across clusters, scientific training courses, soft-skill-courses and research-in-progress workshops will provide new skills and ensure interaction and exchange between PhD fellows (WP6). The strong participation of the non-academic sector in courses, workshops, acting as hosts, providing research data, or acting as practice mentors for PhD fellows will ensure transfer of research into practice (WP7).
