Minimally invasive implantable devices
A minimally invasive implantable device has a generally cylindrical device body that includes: a first end having a first element; a second end having a second element; a wall disposed between the first end and the second end, and having an inner surface and an outer surface, wherein the inner surface defines a lumen extending between the first end and the second end; and at least one protruding element protruding from the outer surface, wherein an outermost diameter of the first element and an outermost diameter of the second element is larger than a diameter of the outer surface of the wall, and the at least one protruding element does not protrude beyond the outermost diameter of the first element or the outermost diameter of the second element.
1. A minimally invasive implantable medical device for treating benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS), comprising:
a first end portion having a first end;
a second end portion having a second end;
a mid-body portion having a mid-body first end and a mid-body second end, wherein a diameter of the mid-body first end is smaller than a diameter of the first end and a diameter of the mid-body second end is smaller than a diameter of the second end;
a first wall disposed between the first end and the mid-body first end, configured in a funnel-shape extending from the first end to the mid-body first end, and having a first inner surface;
a second wall disposed between the mid-body first end and the mid-body second end, and having a second inner surface; and
a third wall disposed between the mid-body second end and the second end, configured in the funnel-shape, and having a third inner surface,
wherein the first inner surface, the second inner surface, and the third inner surface define a continuous lumen extending between the first end and the second end, wherein the mid-body portion includes a mid-body unit, wherein the mid-body unit includes a mid-end having a diameter that is larger than the diameter of the mid-body first end or the diameter of the mid-body second end, and wherein there is a first taper extending from the mid-body first end to the mid-end and a second taper extending from the mid-end to the mid-body second end.
2. The minimally invasive implantable medical device of claim 1 , wherein the first wall, the second wall, and the third wall are integrally formed or are separately attached to each other.
3. The minimally invasive implantable medical device of claim 1 , wherein the mid-body unit includes:
a first unit portion configured in a first funnel shape, and having a first mid-body inner surface; and
a second unit portion configured in a second funnel shape, and having a second mid-body inner surface,
wherein a first end of the first unit portion and a first end of the second unit portion together form the mid-end, and the first mid-body inner surface and the second mid-body inner surface form at least a portion of the second inner surface of the second wall.
4. The minimally invasive implantable medical device of claim 1 , wherein the diameter of the mid-end is not larger than the diameter of the first end.
5. The minimally invasive implantable medical device of claim 1 , wherein the diameter of the mid-end is not larger than the diameter of the second end.
6. The minimally invasive implantable medical device of claim 1 , wherein the first end portion and the second end portion are made of a first material, wherein the mid-body portion is made of a second material, and wherein the first and the second materials are different.
7. The minimally invasive implantable medical device of claim 1 , further comprising a removal component configured to enable removal of the minimally invasive implantable medical device from a patient's body.
8. A minimally invasive implantable medical device for treating benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS), comprising:
a first terminal end;
a second terminal end; and
a wall disposed between the first terminal end and the second terminal end, and having an inner surface and an outer surface, wherein the inner surface defines a lumen extending between the first terminal end and the second terminal end,
wherein the wall has a mid-body portion having a mid-body first end and a mid-body second end, wherein a diameter of the mid-body first end is smaller than a diameter of the first terminal end and a diameter of the mid-body second end is smaller than a diameter of the second terminal end, and
wherein the mid-body portion includes a mid-end having a diameter that is at least equal to the diameter of the first terminal end or the diameter of the second terminal end.
