    Abstract: A medical device includes an incision device operably coupled to a distal end of an elongate catheter. The incision device includes an incision channel, and a retractable cutting apparatus disposed within the incision channel. The retractable cutting apparatus includes a first cutting apparatus link that is rotatably fixed proximate to a distal end of the incision channel and a second cutting apparatus link that is attached to the first link proximal end of the first cutting apparatus link. The first cutting apparatus preferably includes a first cutting surface proximate to the first link proximal end of the first cutting apparatus link and the second cutting apparatus link includes a second cutting surface. The retractable cutting apparatus also includes a guide member coupled to cause the retractable cutting apparatus to move between a retracted position and a deployed position.

    Abstract: A medical device for creating elongated incisions within a pericardium is provided. The device also includes an incision device operably coupled to a distal end of a catheter. The device also includes a retractable cutting apparatus disposed within an incision channel of the incision device. The retractable cutting apparatus includes a gear-actuated blade structured to move between a retracted and a deployed position. In an instance in which the gear-actuated blade is in the retracted position, the gear-actuated blade is disposed within the incision channel. In an instance in which the gear-actuated blade is in the deployed position, the gear-actuated blade at least partially protrudes from the incision channel. The retractable cutting apparatus also includes a torsion gear mechanism attached to the gear-actuated blade. The retractable cutting apparatus also includes a rotatable gear actuator that is structured to move the torsion gear mechanism.

    Abstract: A medical delivery sheath assembly can comprise a first hub portion comprising a first delivery lumen configured to slidably receive at least a portion of a first medical device, and a second hub portion comprising a second delivery lumen configured to slidably receive at least a portion of a second medical device. A longitudinal axis of the first delivery lumen and a longitudinal axis of the second delivery lumen can form an acute angle where a distal portion of the first hub portion and a distal portion of the second hub portion merge. A joint hub portion can be coupled to the distal portion of the first hub portion and the distal portion of the second hub portion. The joint hub portion can comprise a third delivery lumen configured to slidably receive corresponding portions of each the first medical device and the second medical device.

    Abstract: A tapered medical access sheath can comprise an access sheath hub and an access sheath shaft extending distally from the access sheath hub. The access sheath shaft can comprise a first delivery lumen extending from a proximal end of the access sheath shaft to a side opening on a distal portion of the access sheath shaft, the first delivery lumen having a width configured to slidably receive a distal portion of a medical device disposed around a guidewire. The access sheath shaft can comprise a tapered distal end portion disposed distally of the side opening. A recess can extend along a longitudinal dimension of the tapered distal end portion from a proximal end to a distal end of the tapered distal end portion. The recess can be in fluid communication with the first delivery lumen and have a width smaller than the diameter of the first delivery lumen.

    Abstract: A medical device for creating elongated incisions within a pericardium is provided. The medical device includes an incision device operably coupled to a distal end of a catheter. The incision device includes an incision channel defined along the incision device. The medical device further includes a retractable cutting apparatus disposed within the incision channel. The retractable cutting apparatus includes a blade structured to move between a retracted position and a deployed position. In an instance in which the blade is in the retracted position, the blade is disposed within the incision channel. In an instance in which the blade is in the deployed position, the blade at least partially protrudes from the incision channel. The medical device further includes a cutting apparatus actuation mechanism structured to move the blade between the retracted position and the deployed position within a human body.
