A hemostatic device is disclosed. The hemostatic device according to an embodiment of the present invention includes: a balloon which is expanded by a fluid supplied therein; a blood discharge pipe which includes a blood inflow hole at one end and exposes the other end to a lower side of the balloon wherein a certain section of a lower side of the blood inflow hole is surrounded by the balloon; and a fluid flow pipe communicating with the inside of the balloon for supplying or discharging the fluid and extending to a lower side of the balloon. The balloon includes a plurality of protrusions that are formed to protrude outward when the balloon is expanded by the fluid.

Devices, systems, and methods may be used for dilating implants utilizing dilation devices. An implant deployment system may include an inflatable body having a central body configured to press an inner surface of the implant to dilate the implant and having a profile that decreases in diameter along a length of the central body. An inflatable body may include a plurality of segments with varying expansion characteristics.

A constraining structure for use with a balloon catheter can include multiple longitudinal struts and multiple, sinusoidal shaped radial rings. The constraining structure can expand to form a pattern of channels including substantially square windows. The constraining structure can modify, restrict, and control a shape and/or size of the balloon when inflated. Inflating the balloon catheter within the constraining structure can provide nonuniform pressure on a vessel wall adjacent the balloon.

Systems and methods for separating native heart valve leaflets attached together by a fixation device. The system has elongate shaft including a proximal end portion, a distal end portion and a longitudinal axis extending therebetween. The elongate shaft is configured for transvascular delivery of the distal end portion to a native heart valve. A balloon is disposed at the distal end portion of the elongate shaft, and the balloon is inflatable from a collapsed condition to an inflated condition. At least one snare lumen extends along at least a portion of the balloon, the at least one snare lumen having an exit port defined therein. A snare is deployable through the exit port from a delivery position within the at least one snare lumen to an extended position extending beyond the exit port. The snare in the extended position is configured to capture the fixation device.

An implant delivery system includes a catheter, an implant, and a push body. The catheter extends from a first proximal end to a first distal end. The catheter defines an inner lumen extending through the first distal end. The implant includes a second proximal, a second distal end, and a plurality of resilient barbs. The implant is slidably housed within the inner lumen. The implant is compressed in the inner lumen such that the implant bears against an inner diameter of the inner lumen and the implant is retained within the inner lumen by friction. The push body is slidably housed within the inner lumen of the catheter. The push body is adjacent to the second proximal end of the implant.

A catheter having a multilumenal tube surrounded by a slotted hypotube is provided. The catheter has a tube holder that houses the multilumenal tubing and slidably engages the hypotube, and has internal passages configured to receive one of more tubes from the multilumenal tube. The multilumenal tubing separates into one or more tubings, each comprising a lumen, such that the tubings exit the tube holder at different locations. The slotted hypotube slidably engages a key in the tube holder that prevents the multilumenal tubing from rotating relative to the tube holder and the one of more tubings that separate from the multilumenal tubing. Advantages provided by the slotted hypotube/tube holder assembly are described.
