摘要:
A control system for allowing a physician to control the orientation of a medical device or a medical instrument in a variety of directions with one hand. An actuator selectively tensions one or more control cables having ends secured at or adjacent a distal tip of the medical device in order to bend the distal tip in a desired direction. In one embodiment, a physician can adjust the movement of the distal tip in a desired direction without affecting the orientation of the medical device in other directions.

This invention is directed to a flexible device, a first elongate member configured to move the flexible device in a first direction, and a second elongate member configured to move the flexible device in a second direction. The flexible device can include a plurality of articulation links, wherein at least one of the plurality of articulation links can include a body configured to receive the first elongate member and the second elongate member. A cinching element may engage the first elongate member to substantially limit movement between the plurality of articulation links when a tensile force is applied to the first elongate member and may disengage the first elongate member to permit movement between the plurality of articulation links when a tensile force is applied to the second elongate member.

Embodiments of the invention are directed to apparatuses for securing and sealing apertures in tissue and related methods of use. An exemplary apparatus for collapsing an aperture in a wall of tissue can include a base biased to collapse into a collapsed state from an expanded state. The apparatus can also include a plurality of collapsible fingers extending from the base, wherein the collapsible fingers can be configured to collapse about tissue adjacent to and defining the aperture so as to close the aperture in the wall of tissue.

This invention is directed to a medical device having an elongate shaft having a distal end and a controller coupled to the shaft. A control member can extend through at least part of the elongate shaft and at least part of the controller, wherein the control member in a tensioned configuration can be moveable by the controller to control the distal end of the shaft and the control member can be slack in an untensioned configuration. A tensioning mechanism can be configured to move relative to at least one of the elongate shaft and the controller to tension the control member and automatically lock the control member in the tensioned configuration.

This invention is directed to a medical device with a handle and a catheter. The handle can include a body having a proximal end and a distal end, an actuator moveably coupled to the body, and a handle control member coupled to the actuator, wherein the actuator can be configured to move relative to the body to move the handle control member. The catheter can include a shaft having a proximal end and a distal end, wherein the proximal end of the shaft and the distal end of the body can be configured for releasable coupling. The catheter can also include a steering section located along the shaft and a catheter control member coupled to the steering section. A securing member may move relative to at least one of the handle and the catheter to releasably couple the handle control member to the catheter control member.

Drive systems and methods of use are disclosed herein for performing medical procedures on a patient. The drive systems include various handle types and triggers for controlling catheters and end effectors. The various handle types include a flexible handle and ambidextrous handles that can alter the handedness of the handle for particularized use. The handles drive articulation sections of the catheter and end effectors with various degrees of freedom, and include locks for holding the catheter and/or end effector in place. The catheter systems include structures for allowing degrees of freedom, such as notches, mechanical interlocks, and articulation joints. In addition, the catheters articulate via cables or fluids.
