摘要： Devices and methods for locking and/or cutting tethers during a tissue modification procedure are described. In some variations, a tether may be used to tighten tissue by bringing two pieces or sections of the tissue together. The tether, which may be under tension, may be locked to maintain the tension, and excess tether may be severed, using one or more of the devices and/or methods. The devices and/or methods may be used, for example, in minimally invasive procedures.

摘要： Described herein are devices, methods and kits for assessing and/or enhancing the accessibility of a subvalvular space of a heart, accessing the subvalvular space of the heart (e.g., to provide access for one or more other devices), and/or positioning one or more devices in the subvalvular space of the heart. The devices described herein may, for example, comprise catheters that may be used to manipulate one or more chordae tendineae, diagnostic catheters having different sizes and/or shapes (e.g., different curvatures), guide catheters having different sizes and/or shapes (e.g., different curvatures), and visualization catheters. In some variations, the devices, methods, and/or kits may be used to visualize a target site, such as a subannular groove of a heart valve. In certain variations, the devices, methods, and/or kits may be used to manipulate chordae tendineae to provide additional space in a ventricle of a heart (e.g., enhancing the accessibility of the ventricle).

摘要： Surgical treatment of tissue includes electrocauterization of blood vessels interposed between spaced sets of electrodes of opposite polarity, and includes transection of such tissue by a cutter that is mounted between the spaced sets of electrodes for translational and lateral movement relative to the sets of electrodes. Orientations of the sets of electrodes within a range of angles about an elongated axis of a supporting body are controlled by manual movement of an actuator mounted near a proximal end of the body for movement through a smaller range of angles via linkage connecting the actuator to the electrodes. Tissue dissection with gas insufflation to form an anatomical space in tissue is facilitated by a fluid outlet port located near the tissue-dissecting tip at the distal end of the elongated body that delivers through the tissue-dissecting tip to the dissected tissue a fluid under pressure that is supplied along a lumen within the elongated body.

摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis skewed relative to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when the surgeon locates a vessel and side branch of interest, the surgeon extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to the surgical tool. Removable, transparent tips are selectively positioned at the distal end of the cannula for performing dissection and transection via a single cannula. Additionally, the tips are configured to align the apices of the tips with the central axis of the endoscope to maximize the visual field through the tips via the endoscope. Wing-like protrusions on an alternate tip for the cannula facilitate tissue dissection in forming a tunnel in tissue along a target vessel. Swept back forward edges on the wing-like protrusions promote easy tissue dissection using reduced force to advance the cannula and alternate tip through tissue surrounding the target vessel.

摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis that can be skewed relative to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, a surgeon locates a vessel and side branch of interest and extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be deflected to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to the surgical tool. Removable, transparent tips are selectively positioned at the distal end of the cannula for performing dissection and transection via a single cannula. Additionally, the tips are configured to align the apices of the tips with the central axis of the endoscope to maximize the visual field through the tips via the endoscope. Wing-like protrusions on an alternate tip for the cannula facilitate tissue dissection in forming a tunnel in tissue along a target vessel. Swept back forward edges on the wing-like protrusions promote easy tissue dissection using reduced force to advance the cannula and alternate tip through tissue surrounding the target vessel.
摘要翻译：牵开器和手术工具定位在套管内，并且牵开器的解剖支架位于套管的远端。牵开器包括具有大致平行于套管轴线的轴线的第一部分和具有相对于套管轴线可偏斜的轴线的第二部分。解剖支架位于牵开器的第二部分的远端，并且可以包括两个基本上平行的间隔开的腿，其中牵开器成形为相对于腿的轴线倾斜的平面之间的环中，并且与环路远离手术工具。因此，在操作中，外科医生定位感兴趣的血管和侧支，并且将牵开器延伸到支架中，以将解剖支架中的血管摇动。一旦收起，收缩器可能被偏转以促使血管远离套管的轴线以隔离侧分支以暴露于外科手术工具。可移除的透明尖端选择性地定位在套管的远端，以通过单个插管进行解剖和切断。另外，尖端被配置成将尖端的顶点与内窥镜的中心轴线对准，以通过内窥镜通过尖端最大化视野。用于插管的备选尖端上的翼状突起促进组织解剖，以沿着靶容器在组织中形成隧道。在翼状突起上扫掠前部前缘，通过减小力促进组织夹层，从而使插管和交替的尖端通过围绕目标血管的组织。
