Definitions

  • FIG. 3D illustrates the portion assembly of FIG. 2 in a third state of insertion into a patient, in accordance with some embodiments.
  • proximal portion or a “proximal-end portion” of, for example, a portion disclosed herein includes a portion of the portion intended to be near a clinician when the portion is used on a patient.
  • proximal length of, for example, the portion includes a length of the portion intended to be near the clinician when the portion is used on the patient.
  • proximal end of, for example, the portion includes an end of the portion intended to be near the clinician when the portion is used on the patient.
  • a “distal portion” or a “distal-end portion” of, for example, a portion disclosed herein includes a portion of the portion intended to be near or in a patient when the portion is used on the patient.
  • a “distal length” of, for example, the portion includes a length of the portion intended to be near or in the patient when the portion is used on the patient.
  • a “distal end” of, for example, the portion includes an end of the portion intended to be near or in the patient when the portion is used on the patient.
  • the distal portion, the distal-end portion, or the distal length of the portion can include the distal end of the portion; however, the distal portion, the distal-end portion, or the distal length of the portion need not include the distal end of the portion. That is, unless context suggests otherwise, the distal portion, the distal-end portion, or the distal length of the portion is not a terminal portion or terminal length of the portion.
  • the proximal section 120 may be configured to be manually inserted into a lumen of a portion.
  • the proximal section 120 may be configured for manual handling by a clinician and may comprise a flexural stiffness that facilitates manual displacement of the proximal section 120 distally into the portion without plastic deformation, kinking, and/or breaking.
  • the stiffness of the proximal section 120 may enhance a stiffness of the portion, i.e., provide a column strength to the portion to aid insertion of the portion into the patient.
  • the proximal section 120 may comprise a diameter 124 consistent with disposition of the proximal section 120 within the portion.
  • the diameter 124 may be the same, larger, or smaller than a diameter 114 of the distal section 110.
  • the proximal section 120 may be configured to be at least partially disposed within the vasculature of a patient. In some embodiments, a length 125 of the proximal section 120 may be longer than the length 123 of the distal section 110.
  • the proximal section 120 may include indicia 128.
  • the indicia 110 may be indicative of a distance to a distal end 126 of the proximal section 120.
  • the distal end of the portion may not be visible to a clinician, such as an instance where the distal end is disposed within the patient.
  • a location of indicia 128 with respect to a proximal end of the portion may indicate a position of the distal end 126 of the proximal section 120 with respect to the distal end of the portion.
  • the indicia 110 may also be indicative of a distance to the distal end 101 of the section 100.
  • a clinician may observe the indicia 128 to assess the position of the distal end 101 along the vasculature of the patient.
  • FIG. 2 illustrates a portion assembly 200 including the section 100 of FIG. 1A.
  • FIG. 2 illustrates the portion assembly 200 in a ready-to-deploy state.
  • the portion assembly 200 includes a portion 202 and an introducer 206 coupled together.
  • the portion 202 may be a monoluminal or multiluminal portion including at least a primary lumen 208 extending through the portion 202.
  • the portion 202 includes a soft portion tube 220, a portion hub 222, and one or more extension legs 224 corresponding with one or more lumens extending at least partially through the soft portion tube 220.
  • the primary lumen 208 corresponds with a primary leg 228.
  • the portion tube 220 includes a distal tip 230 about a distal-end portion of the soft portion tube 220 corresponding to the distal end of the portion 202.
  • the introducer 206 includes an introducer portion 232 and an introducer needle 226.
  • the introducer portion 232 includes an introducer-portion tube 234, an introducer-portion hub 236 about a proximal-end portion of the portion tube 234, and a distal tip 238 at a distal end of the introducer-portion tube 234.
  • the introducer 206 is coupled to the portion 202, such that the introducer-portion tube 234 is disposed within the primary lumen 208. When coupled together, the introducer-portion tube 234 extends 1) distally beyond the distal tip 230 of the portion and 2) proximally beyond a proximal end of the primary leg 228.
  • the portion 202 includes a side aperture 204 extending through a wall of the soft portion tube 220 into the primary lumen 208 and further through a wall of the introducer-portion tube 234 into a single lumen of the introducer portion 232.
  • the introducer needle 226 is disposed through the side aperture 104 and into the single lumen of the introducer portion 232 such that a beveled tip 246 of the introducer needle 126 extends past the distal tip 238 of the introducer portion 232 for establishing a percutaneous puncture.
  • the side aperture 204 may be omitted and the introducer needle 226 may be inserted into the introducer portion 232 via the introducer-portion hub 236.
  • the length 125 of proximal section 120 may be sufficiently long to extend from a proximal end of the portion to a distal end of the portion. In some embodiments, the length 125 may be sufficiently long so that, when the distal end 126 of the proximal section 120 is disposed adjacent the distal end of the portion, a portion of the proximal section 120 extends proximally away from the proximal end of the portion. The extending portion of the proximal section 120 may be sufficiently long such that the clinician may grasp and manipulate the proximal section 120.
  • FIG. 3B illustrates a second state of insertion wherein the portion 202 remains at the same position as illustrated in FIG. 3 A.
  • the process of inserting the portion 202 as illustrated in FIGS. 3B and 3D may be repeated multiple times during insertion of the portion 202.
  • the steps of 1) inserting the portion a distance and 2) proximally retracting the section 100 relative to the portion 202 a corresponding distance, so that the distal end 126 remains in adjacent the blood vessel puncture site 312, may be repeated one or more times as the portion 202 is inserted to its intended final position.
  • Any methods disclosed herein include one or more steps or actions for performing the described method.
  • the method steps and/or actions may be interchanged with one another.
  • the order and/or use of specific steps and/or actions may be modified.
  • sub-routines or only a portion of a method described herein may be a separate method within the scope of this disclosure. Stated otherwise, some methods may include only a portion of the steps described in a more detailed method.
  • a method may further include a step of establishing a needle tract from an area of skin 300 to the blood vessel 310 of the patient with the beveled tip 246 of the introducer needle 226.
  • the method may include advancing the introducer needle 226 through the side aperture 204.
  • the introducer needle 226 may extend through the side aperture 204 of the soft portion tube 220 of the portion 202, extend through the side of the introducer-portion tube 234 of the introducer portion 232, and exit out of the distal tip 238 of the introducer portion 232.
  • a method may further include a step of withdrawing the introducer needle 226 from both the blood vessel 310 and the portion assembly 200 leaving the access section 248 and the introducer portion 232 inserted within the blood vessel 310.
  • a method may further include a step of advancing the portion 202 through the vasculature along the section 100.
