A distal tip of a duodenoscope may comprise: a first side surface; a second side surface; a top surface; a bottom surface; and a distal surface. The first side surface, the top surface, and the distal surface meet at a first junction. The first side surface, the bottom surface, and the distal surface may meet at a second junction. The second side surface, the bottom surface, and the distal surface may meet at a third junction. The second side surface, the top surface, and the distal surface may meet at a fourth junction. The first junction and the fourth junction may be approximately symmetrical. The second junction and the third junction may be approximately symmetrical. The first junction and the third junction may be approximately symmetrical. The second junction and the fourth junction may be approximately symmetrical.

Abrégé

A medical delivery device that includes a body, a fluid source configured to store a pressurized fluid, an enclosure configured to store an agent, the enclosure is movably coupled to the body, and a first actuator configured to release the pressurized fluid from the fluid source into the body. The enclosure is configured to move relative to the body between a first position and a second position. The enclosure is fluidly decoupled from the fluid source when in the first position such that the pressurized fluid released into the body is not in fluid communication with the agent stored in the enclosure. The enclosure is fluidly coupled to the fluid source when in the second position such that the pressurized fluid released into the body is in fluid communication with the agent stored in the enclosure.

Abrégé

A radiofrequency perforation system for accessing a location in or near a patient's heart is disclosed. The system includes a radiofrequency puncture wire having a wire proximal portion and a wire distal portion including an electrically active distal tip. The system further includes an elongated catheter defining a lumen adapted to receive and allow longitudinal translation of the radiofrequency puncture wire therein, the elongated catheter having a proximal portion and a distal portion, the proximal portion including a hub and the distal portion including a distal tip. The distal tip of the elongated catheter includes an inner catheter liner layer, an intermediate flexible heat shielding layer, and an outer radiopaque layer.

Abrégé

A steerable sheath is disclosed. The steerable sheath includes an elongate member, the elongate member having a proximal portion and a distal portion terminating in a deflectable distal tip. The steerable sheath further includes a handle having a handle proximal portion and a handle distal portion that is connected to the proximal portion of the elongate member. The handle of the steerable sheath includes a knob positioned at the distal portion of the handle; a slider running through a portion of the handle having a raised thread and an inverted thread; and a position ring located proximate a position indicator, wherein rotation of the knob acts upon the raised thread to cause a linear movement of the slider which acts upon the inverted thread to cause a rotational movement of the position ring.

Abrégé

An electrosurgical device for use with a radiofrequency (RF) energy source to provide RF energy is disclosed. The electrosurgical device includes a delivery component having an elongate shaft having a distal portion and a proximal portion and forming a lumen. The distal portion includes a delivery component distal end. A crossing member is disposed within the lumen. The crossing member includes a crossing member distal tip extendable from the delivery component distal end to deliver the RF energy from the RF energy source. A handle is coupled to the proximal portion of the shaft. An actuator is coupled to the handle. The actuator extends the crossing member distal tip from the delivery component distal end and couples the RF energy source to the crossing member such that RF energy is delivered to the distal tip of the crossing member.
