  • Patent number: 10806348
    Abstract: A method for introducing a shaped portion of an elongate medical instrument into a body of a subject includes at least partially straightening the shaped portion of the elongate medical instrument. A retention element may be introduced into an interior of the shaped portion of the elongate medical instrument to place and/or maintain the shaped portion in an at least partially straightened configuration. Such straightening may be accomplished without application of external force to an exterior of the shaped portion. With the retention element in place, the shaped portion may be introduced to a desired location within a hollow interior of an internal organ. The retention element may then be removed to enable the shaped portion to return to its desired shape. A straightening apparatus includes a retention element that can place and/or maintain a shaped portion of an elongate medical instrument in an at least partially straightened configuration without assistance of external force.

  • Patent number: 10806911
    Abstract: A medical instrument includes a shaft, a distal-end assembly and a puller-wire. The shaft is configured for insertion into a body of a patient. The distal-end assembly, which is coupled to the shaft, includes a telescopic assembly, configured to elongate so as to collapse the distal-end assembly, and to compress so as to expand the distal-end assembly. The distal-end assembly further includes an elastic element, coupled to self-elongate and thus elongate the telescopic assembly. The distal-end assembly also includes an inflatable balloon, which is coupled to the telescopic assembly and is configured to collapse by the telescopic assembly elongating, and to expand by the telescopic assembly compressing. The puller-wire runs through the shaft and is connected to a distal end of the telescopic assembly, and is configured, when pulled, to compress the telescopic assembly.

  • Patent number: 10507307
    Abstract: The present invention is directed to a guidewire configured to reduce the incidence of medical accidents when using guidewires including, but not limited to, the incidence of guidewires accidentally being pushed completely into a patient through a needle in the patient, guidewires accidently being left inside patients after the placement of central venous (and other) catheters, and guidewires accidently being left inside patients after removal of the catheter (at the end of an operation of other medical procedure). In particular, an intermediary portion (either in the form of a new shape (referred to herein as “an obstruction portion”) or an alternate (e.g., more flexible) material) of the guidewire inhibits further advancement into the needle with pushing motion. (The intermediary portion can be implemented as an additional portion connected between the patient-side portion and the doctor-side portion of the guidewire as well.

  • Patent number: 10493234
    Abstract: A catheter has excellent torque transmissivity and excellent flexibility, thus enabling easy insertion of the catheter into a blocked portion of a blood vessel. Additionally, the catheter easily restores to its original form even when the catheter is curved and deformed a large amount. Thus, a break at a border area between a catheter main body part and a distal end tip is prevented when the catheter is bent and deformed. This improves the operability of the catheter with a combination device such as a guide wire. The catheter includes a hollow coil body formed of at least one helically wound stranded wire. The at least stranded wire includes a plurality of wires wound into a helical structure.

  • Patent number: 10433904
    Abstract: Medical devices, systems, and methods for treating patients with tissue ablation include catheter systems having bi-modal steering mechanisms, which are capable of both linear and loop ablation. In other words, the catheter system may have two different steering modes: two-dimensional and three-dimensional. In the first and second steering modes, the steering actuator may cause one or more portions of the catheter shaft to bend in different planes. A steerable ablation catheter may include treatment elements such as electrodes at its distal end and along the catheter shaft, each of which may map, pace, and ablate.
