摘要:
A method and apparatus for printing a pattern on a substrate, by applying a photoresist layer over the substrate; locating a laser direct-imagining exposure head to print the pattern on the substrate by the application of one or more laser beams to the photoresist layer on the substrate while relative movement is effected between the exposure head and the substrate; and controlling the drive and the exposure head to cause the exposure head to print a first portion of the pattern on a first portion of the substrate at a first (normal) resolution, and a second portion of the pattern on a second portion of the substrate at a second (higher) resolution.
摘要:
Apparatus is provided, including first and second longitudinal members coupled at respective first portions thereof to tissue surrounding the ventricle. The first portion of at least the first longitudinal member is coupled to a tissue anchor, and respective second portions of the first and second longitudinal members are coupled to respective first and second leaflets of a cardiac valve. The longitudinal members are arranged with respect to the tissue anchor and the portion of tissue surrounding the ventricle in a manner which facilitates adjustment of a degree of tension of the first and second longitudinal members to draw the first and second leaflets together. A longitudinal-member-coupling device is coupled to the first and second longitudinal members, and is advanceable toward a ventricular surface of the first and second leaflets, and responsively to draw together the first and second longitudinal members. Other applications are also described.
摘要:
A steering tool including an internal tube disposed inside an external tube, the internal and external tubes being arranged for longitudinal axial movement relative to one another, wherein a distal end of the internal tube is fixedly joined to a distal end of the external tube, and at least one of the internal and external tubes is slotted near the distal end thereof, and wherein the longitudinal axial movement causes bending of the distal ends of the tubes.
摘要:
Apparatus for use with an implant configured to be coupled to cardiac tissue of a patient, the apparatus including: a tissue anchor including: a distal tissue coupling element configured to couple the tissue anchor to the cardiac tissue of the patient, and a proximal implant-receiving element configured to receive at least a portion of the implant and facilitate coupling of the implant to the tissue anchor. The proximal implant-receiving element includes an implant-restraining element coupled to a portion of the implant-receiving element, the implant-restraining element being configured to restrain the implant from separating from the implant-receiving element. Other applications are also described.
摘要:
Apparatus is provided for use with at least one tissue-adjustment device, including a tissue-engaging element having a distal portion configured to engage at least a first portion of tissue of a patient, and having a proximal portion. At least one docking station is coupled to the proximal portion of the tissue-engaging element and is configured to be coupled to the at least one tissue-adjustment device. The docking station includes a locking mechanism configured to lock the tissue-adjustment device to the tissue-engaging element. At least one guide member is reversibly coupled to the at least one docking station and is configured for facilitating slidable advancement of the at least one tissue-adjustment device toward the tissue-engaging element. Other applications are also described.

摘要:
Apparatus is provided, including a locking mechanism, an implant, and a flexible strip within the implant having a plurality of recesses. A perimeter of the strip shortens and expands when the first end of the strip is advanced bidirectionally with respect to a second end of the strip. The locking mechanism includes a moveable recess-engaging portion, a mechanical support removably coupled to the recess-engaging portion, and a force applicator which maintains the recess-engaging portion in a position in which the recess-engaging portion is not disposed in any of the recesses. Upon decoupling of the mechanical support from the recess-engaging portion, the force applicator restricts motion of the plurality of recesses of the strip with respect to the second end of the strip, by facilitating positioning of the recess-engaging portion in one of the plurality of recesses. Other embodiments are also described.
摘要:
A needle assembly adapted for fluid communication with a vial containing a substance to be delivered to a subject, the needle assembly including a needle held in a needle holder, the needle holder confined to move in a housing, and an activation mechanism for activating delivery of the substance through the needle, the activation mechanism including a safety latch that initially impedes movement of the needle holder, wherein when the safety latch is placed on the subject, the safety latch moves to a position that permits moving the needle holder to cause the needle to protrude outwards of the housing to pierce the subject to allow administration of the substance to the subject, characterized by a biasing device arranged to apply a biasing force on the needle to cause the needle to protrude outwards of the housing to pierce the subject, and needle release apparatus including a needle arrestor that initially blocks movement of the biasing device and which releases the biasing device when the safety latch moves to the position that permits moving the needle holder to cause the needle to protrude outwards of the housing.
