Abstract
According to one aspect, a medical device including a shaft having a proximal and a distal end. The medical device may also include a handle coupled to the proximal end of the shaft. The medical device may further include a body at the distal end of the shaft. The body may have a wall defining a lumen within the body, and the lumen may have a longitudinal axis. The wall may include a protrusion at the distal end of the body, and the protrusion may be defined by a gap in the wall and may have a sharp portion configured to grasp tissue. The gap may extend proximally from the distal end of the body, and edges of the wall defining the gap may be transverse to the longitudinal axis.
Claims19
A medical device, comprising:
- a shaft having a proximal end and a distal end;
- a handle coupled to the proximal end of the shaft;
- and
- a body at the distal end of the shaft, the body having a wall defining a lumen within the body, the lumen having a longitudinal axis, wherein the wall includes a protrusion at a distal end of the body, the protrusion being defined by a gap in the wall and having a sharp portion configured to grasp tissue, wherein the gap extends proximally from the distal end of the body, and a first edge of the wall defining the gap meets a second edge of the wall defining the gap at an obtuse angle, and wherein each of the first edge and the second edge faces a proximal direction, wherein the gap in the wall has an open distal end at a distal most end of the body and is defined by distalmost edges of the body, wherein a portion of the body is distal to the second edge.
A medical device, comprising:
- a shaft having a proximal end and a distal end;
- and
- a tubular body at the distal end of the shaft, the tubular body including a wall, wherein the wall includes a protrusion at a distal end of the tubular body, the protrusion defined by a slot in the wall, the slot being transverse to a longitudinal axis of the tubular body, wherein the slot extends proximally from the distal end of the tubular body and defines an apex at an end of the protrusion;
- wherein the slot includes a proximal section and a distal section, the distal section extends proximally from a distalmost end of the tubular body, and the proximal section is defined by a first edge, a second edge, and a third edge of the wall, wherein the first edge and the third edge each extends substantially parallel to a distalmost edge of the tubular body, and wherein the first edge and the third edge face each other.
A medical device, comprising:
- a shaft having a proximal end and a distal end;
- and
- a tubular body at the distal end of the shaft, the tubular body including a wall and a longitudinal lumen, wherein the wall of the tubular body includes (1) a proximal portion having a proximal inner diameter and (2) a distal portion having a distal inner diameter and a plurality of protrusions, where each of the plurality of protrusions is tapered to an apex configured to penetrate tissue, wherein the plurality of protrusions are circumferentially spaced around a distal end of the tubular body, and wherein the proximal inner diameter equals the distal inner diameter;
- wherein the tubular body includes a plurality of slots in the wall of the tubular body that extend proximally from the distal end of the tubular body, wherein each of the slots includes a proximal section and a distal section, the proximal section extending at an obtuse angle relative to the distal section;
- wherein each of the plurality of protrusions is distal to and longitudinally aligned with a distal-facing edge of the tubular body.
