20100161043 | IMPLANTATION OF REPAIR CHORDS IN THE HEART - Apparatus is provided for adjusting at least one dimension of an implant, including a rotatable structure having first and second openings and a channel extending between the first and second openings. The channel allows passage therethrough of an elongate tool. The second end of the structure has a lower surface having one or more recesses along a circumference thereof. A mechanical element provides a protrusion that is disposed within one of the recesses of the rotatable structure during a resting state of the mechanical element, in a manner that restricts rotation of the rotatable structure. The mechanical clement comprises a depressible portion coupled to the protrusion disposed in communication with the second opening of the lower surface, and configured to dislodge the protrusion from within the recess in response to a force applied thereto by the elongate tool. Other applications are also described. | 06-24-2010 |
20110295146 | REMOTE PRESSURE SENSING SYSTEM AND METHOD THEREOF - The present invention relates to a monitoring system and method for use with a body of a subject. The system comprises a medical device, having a portion thereof configured to be placed inside the subject's body, said portion of the medical device being configured to be propelled by fluid pressure through a body lumen; at least two pressure sensors accommodated remotely from the subject's body at two different spaced-apart positions outside the subject's body and configured and operable to detect pressure at the two spaced-apart remote positions; said at least two pressure sensors being in fluid communication with at least one site inside the subject's body, a relation between the pressure at said at least one site and the pressures at said two spaced-apart remote positions being thereby indicative of the fluid pressure at said at least one site. | 12-01-2011 |
20120136436 | ADJUSTABLE ANNULOPLASTY DEVICES AND ADJUSTMENT MECHANISMS THEREFOR - Apparatus is provided including an implant structure ( | 05-31-2012 |
20120330411 | CLOSED BAND FOR PERCUTANEOUS ANNULOPLASTY - An implantable structure includes a flexible sleeve, having first and second sleeve ends, and a contracting assembly, which is configured to longitudinally contract the sleeve, and includes a contracting mechanism, which is disposed longitudinally at a first site of the sleeve, and a longitudinal contracting member, having (a) a first member end, (b) a second member end, which is coupled to the sleeve longitudinally at a second site longitudinally between the first site and the second sleeve end, exclusive, and (c) a first member end portion, which is coupled to the contracting mechanism. The sleeve is arranged in a closed loop, such that first and second portions of the sleeve together define a longitudinally overlapping portion of the sleeve. The implantable structure is configured such that the contracting assembly longitudinally applies a longitudinal contracting force only between the first and the second sites, and not along the overlapping portion. | 12-27-2012 |
20130096672 | APPARATUS AND METHOD FOR GUIDE-WIRE BASED ADVANCEMENT OF A ROTATION ASSEMBLY - Apparatus is provided, comprising (1) a guide member, (2) a tissue-adjustment mechanism having (a) an upper surface and a lower surface, (b) at least one first opening at the upper surface, (c) at least one second opening at the lower surface, and (4) a channel extending between the first and second openings, the channel facilitating advancement of the tissue-adjustment mechanism along the guide member; and (3) at least one repair chord coupled at a first portion thereof to the tissue-adjustment mechanism and having at least a first end that is configured to be coupled to a portion of tissue of a patient, the repair chord being configured to adjust a distance between the portion of tissue and the tissue-adjustment mechanism, in response to adjustment of the repair chord by the tissue-adjustment mechanism. Other embodiments are also described. | 04-18-2013 |
20130116776 | EXTERNAL AORTIC RING AND SPOOL MECHANISM THEREFOR - A method for repairing an aortic valve of a heart of a patient is provided, the method comprising (1) placing around a portion of an aorta of the patient in a vicinity of the aortic valve, an adjustable implant structure comprising an adjusting mechanism coupled to a first portion of a flexible contraction member; and (2) adjusting a dimension of the aortic valve by adjusting a dimension of the implant structure by rotating a rotatable structure of the adjusting mechanism. Other embodiments are also described. | 05-09-2013 |
20130116780 | IMPLANT HAVING MULTIPLE ROTATIONAL ASSEMBLIES - Apparatus is provided, comprising (1) an annuloplasty structure, shaped to define a perimeter, and configured to be disposed at the annulus of the native valve of the patient; (2) a first adjusting mechanism, coupled to the annuloplasty structure, and configured to adjust the perimeter; (3) at least one longitudinal flexible member, having a first end portion, and a second end portion that is configured to be coupled to tissue of the ventricle of the heart of the patient; and (4) at least a second adjusting mechanism, coupled to the annuloplasty structure such that the second adjusting mechanism is slidable around at least part of the perimeter, coupled to the first end portion of the longitudinal flexible member, and configured to adjust a distance between the second adjusting mechanism and the second end portion of the longitudinal flexible member. Other embodiments are also described. | 05-09-2013 |
20140142695 | CONTRACTIBLE ANNULOPLASTY STRUCTURES - Apparatus is provided including an implantable structure ( | 05-22-2014 |
20140243963 | ANNULOPLASTY RING DELIVERY CATHETHERS - Apparatus is provided, including a first catheter having a distal end portion transluminally advanceable to a vicinity of an anatomical site, a second catheter having a distal end portion advanceable through a first lumen and out of the first lumen, and a longitudinal implant, advanceable through the second lumen and out of the second lumen. The first and second catheters are assembled to facilitate sliding of the first and second catheters and of the implant, to configure them to assume a multi-bend formation having first and second bends separating first, second, and third domains. The first domain includes parts of the first and second catheters. The second domain includes the distal end portion of the second catheter, part of the implant, and none of the first catheter. The third domain includes part of the implant and none of the first nor second catheters. Other embodiments are also described. | 08-28-2014 |
