Abstract: 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.

Abstract: A steerable catheter, such as a dilator, includes an elongated shaft including a proximal end portion and a distal end portion, an end effector disposed at the distal end portion of the shaft, and a handle disposed at the proximal end portion of the shaft. The end effector includes a dilation portion disposed proximate the distal end portion of the shaft, a transition portion disposed distally on the dilation portion, and a distal tip portion disposed distally on the transition portion. The tip portion is movable relative to the dilation portion. The handle includes a tip portion steering actuator enabling a user to steer the tip portion. The tip portion has a tip portion diameter. The dilation portion has a dilation portion diameter which is greater than the tip portion diameter. The transition portion tapers from the tip portion diameter to the dilation portion diameter.

Abstract: A head stabilization system including a head restraint mechanism and a head harness configured to engage a head of a patient. The head restraint mechanism is configured to be operatively disposed on a patient support device and includes a generally vertically upstanding arcuate tilt guide. The head harness is releasably attachable to and at least partially supported by the head restraint mechanism. The head harness is selectively repositionable generally vertically relative to the tilt guide. The head restraint mechanism is configured to stabilize the head harness relative to the patient support device. The head restraint mechanism is configured to selectively allow lateral flexion of a neck of the patient, lateral rotation of the head of the patient, and extension and flexion of the neck of the patient.

Abstract: An enhanced flexibility catheter shaft having an elongate flexible body with a proximal end, a distal end, and at least one lumen extending therethrough.

Abstract: An enhanced flexibility catheter shaft having an elongate flexible body with a proximal end, a distal end, and at least one lumen extending therethrough. A distal, flexible section on the body has a ribbed or corrugated tubular membrane having at least a first reinforcement structure, such as a first helical support, on a radially exterior or interior surface of the tubular membrane and optionally a second reinforcement structure, such as a second helical support, on the other of the radially interior or exterior surface of the tubular membrane.

Abstract: A surgical stapler for use during an open hernia repair comprises an elongated shaft having a handle at its proximal end and a downwardly disposed staple discharge head at its distal end. A squeeze trigger on the handle is operable to cause a supply of staples to be selectively discharged from the port. One or more mesh manipulators are provided on the head and serve to assist in positioning or otherwise manipulating surgical mesh prior to fixation with the staples. In one form, the stapler includes a chamfered portion, a cantilevered portion, and a retention lip to prevent multiple staples from deploying after a single pull of the trigger. Further, in this form, the stapler prevents incomplete staple formation if side load forces are applied during insertion of a staple in tissue thereby reducing waste of staples.

Abstract: A surgical stapler for use during an open hernia repair comprises an elongated shaft having a handle 120 at its proximal end and a downwardly disposed staple discharge head 130 at its distal end. A squeeze trigger 122 on the handle 120 is operable to cause a supply of staples 160 to be selectively discharged from the port. One or more mesh manipulators 150 are provided on the head 130 and serve to assist in positioning or otherwise manipulating surgical mesh prior to fixation with the staples.

Abstract: A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.
