A medical power supply system includes: a medical device including an elongated insertion section, a power receiving unit including a power receiving member and movable relative to the insertion section in a longitudinal direction of the insertion section, and a biasing unit biasing the power receiving unit toward a distal end side of the insertion section; and a guide unit including a power transmitting unit including a power transmitting member, the insertion section being inserted into the guide unit. When the insertion section is inserted into the guide unit to a predetermined amount, the power receiving unit comes in contact with the power transmitting unit with being biased by the biasing unit, and the power transmitting member and the power receiving member face each other in an axial direction of the insertion section and have a positional relation in which wireless power transmission is possible.

A catheter may be used for treating chronic venous insufficiency (CVI) by remodeling a venous valve within a vein. The catheter is advanced through the vein to a position proximate the venous valve, the catheter including a hollow needle extendable out a first side wall of the catheter and an inflatable balloon located on a second, opposing, side wall of the catheter. The inflatable balloon is inflated in order to urge the catheter towards a vessel wall opposite that of the inflatable balloon. The hollow needle is advanced at least partially into the vessel wall opposite that of the inflatable balloon and a bulking agent is injected near the venous valve in order to remodel the venous valve. The bulking agent may be injected within a subintimal space within the vessel wall, or into an advential space outside of the vessel wall.

The present teachings relate generally to a medical flexible needle assembly (10), comprising a needle portion (20) disposed at a distal end (12) of the assembly; a stiff portion (30) disposed at a proximal end 14 of the assembly; an flexible portion disposed between and interconnecting the needle portion and the stiff portion, including a flex distal portion (42), a flex proximal portion (44); and a jacketing member (50) disposed about the assembly (10) over at least part of the flexible portion (40); characterized in that the jacketing member (50) includes one or more coupled regions (60) and one or more decoupled region (70), wherein in at least one or more of the one or more coupled regions (60) are located proximally, distally, or both of the flexible portion (40).

The disclosed invention provides a handle for controlling movements of a transseptal insertion shaft which is suitable for facilitating precise and safe transseptal puncture of a cardiac interatrial septum, and a transseptal puncture system that include a transseptal insertion shaft and a handle to control movements of the transseptal insertion shaft. The handle includes two twister thread half shells, a nut inner and nut outer placed inside the two twister thread half shells, a first pull wire connected to a first side of the transseptal insertion shaft and coupled to the nut inner, a second pull wire connected to a second side of the transseptal insertion shaft and coupled to the nut outer. The nut inner and nut outer rotate in opposite directions to each other when the two twister thread half shells are turned in a direction.

Systems, devices and methods for performing medical procedures in the intestine of a patient are provided. A medical device for performing a treatment and/or a diagnostic procedure can include an elongate shaft assembly comprising at least a shaft assembly first section comprising a distal section of the shaft assembly, and a shaft assembly second section proximal to the first section, and a functional assembly positioned on the shaft assembly first section. Additional sections of the shaft assembly can be included, and each section can comprise a different construction, such as to achieve a different stiffness as described herein. Variable stiffness along the length of the shaft assembly can be provided to aid in translation of the device through the patient's GI tract (e.g. through the stomach and into the small intestine), as described herein.

An apparatus is for an elongated sheath assembly configured to receive, at least in part, an elongated dilator assembly. The apparatus includes a dilator-receiver device configured to be installed to the elongated sheath assembly. A dilator-receiver mover is configured to be mounted, at least in part, to the elongated sheath assembly. The dilator-receiver mover is configured to be operatively connected to the dilator-receiver device. The dilator-receiver mover is also configured to selectively move the dilator-receiver device along a predetermined distance.

An apparatus is disclosed for an optimized transseptal procedure that reduces the number of devices that are used in order to minimize procedural time, complexity and cost. The apparatus comprises a hybrid dilator that comprises the combined functionality of a transseptal sheath and dilator assembly. The hybrid dilator comprises: a dilator shaft defining a lumen for receiving a crossing device therethrough, a distal tip having an outer diameter which tapers down to an outer diameter of the crossing device for providing a smooth transition and a hub coupled with a side arm coupled to the dilator shaft.

Devices, systems, and methods for use with suction within a mammalian body. In an exemplary embodiment of a device of the present disclosure, the device comprises one or more of the following: an inner tube, an outer tube, and a foldable portion, whereby movement of the two tubes relative to one another causes the foldable portion to form a suction cup, and conversely causes a suction cup to form a foldable portion, depending on the direction of relative movement.

A transseptal needle or punch. The transseptal punch includes a stylet with a tube with a side window and a cutting wire disposed within the tube, with a sharp cutting segment disposed proximate the window. The sharp cutting segment can be expanded radially outwardly from the window by translation of the cutting wire proximal end within the tube.

A needle apparatus having a sheath with a protective hypotube insert and a method of making the needle sheath. An example needle apparatus includes a handle, a needle having a proximal end connected to the handle and a sheath. The sheath is configured to receive of the needle. The sheath includes a proximal end connected to the handle, a distal end, a lumen and the protective insert. The lumen passes from the proximal end to the distal end of the sheath. The protective insert is received within the lumen at the distal end of the sheath when force and/or heat are applied.
